Black Box vs White Box Testing: What are the Key Differences?

Test plans and test strategies are key parts of a solid software quality assurance (QA) system. While they often work together and support each other, they actually have different goals. 



So, what’s the difference?



A lot of people get confused here since there’s some overlap in how they’re used. This blog will break down the differences between a test strategy and a test plan. We&#8217;ll start by explaining each term and then compare their main differences.

<h2 id="test-strategy-vs-test-plan-overview">Test Strategy vs Test Plan: Overview</h2>



<h3 id="h-what-is-a-test-plan">What is a Test Plan?</h3>



The <a href="https://testsigma.com/blog/test-plan/" target="_blank" rel="noreferrer noopener">test plan</a> (sometimes termed a QA test plan) may be considered the instruction manual or guide for an organization’s testing effort. It lists all the activities in a QA project in one place, creating a schedule, identifying the scope of the project, defining roles and responsibilities, highlighting risks, entry and exit criteria, testing objectives, and so on.



Generally, the test plan is designed based on software requirements. Ideally, test plans should feature the risks foreseen in the <a href="https://www.netguru.com/blog/qa-projects" target="_blank" rel="noreferrer noopener">QA project</a> so that QA managers may prioritize the testing process by risk.



<h3 id="h-what-is-a-test-strategy">What is a Test Strategy?</h3>



Test strategy is a comprehensive document that describes the approach to performing <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a>. It lets the project managers, developers, and testers know of the critical issues of the process. Creating an effective test strategy is a skill one may develop with experience.



The test strategy describes how the risks must be mitigated at the <a href="https://testsigma.com/blog/levels-of-testing/" target="_blank" rel="noreferrer noopener">test level</a>, what criteria are required to apply, and the type of testing that needs to be performed. The testing strategy is shared with the entire team so that everyone onboard follows a common approach and mindset to testing.



<h2 id="h-test-strategy-vs-test-plan-key-differences">Test Strategy VS Test Plan: Key Differences</h2>



The difference between a test plan and a test strategy is that a test plan documents the scope, objective, and key elements of software testing, whereas a test strategy defines the techniques and approaches to testing.



<figure class="wp-block-table"><table><tbody><tr><td>Feature</td><td>Test Plan</td><td>Test Strategy</td></tr><tr><td>Definition</td><td>A document outlining the scope and approach for testing.</td><td>A set of guidelines for testing methods and techniques.</td></tr><tr><td>Key Elements</td><td>ID, Features, Test Types, Criteria, Deliverables, Responsibilities, Schedule</td><td>Scope, Formats, Processes, Tools, Reporting, Communication</td></tr><tr><td>Execution &amp; Management</td><td>Defines who, when, and how testing will be conducted.</td><td>Defines which modules and techniques will be used for testing.</td></tr><tr><td>Specificity</td><td>Detailed specifications for test cases.</td><td>Outlines general testing approaches.</td></tr><tr><td>Updatability</td><td>Can be updated throughout the project.</td><td>Typically remains static for the project.</td></tr><tr><td>Risk Identification</td><td>Identifies potential issues and dependencies.</td><td>Serves as a long-term plan for risk assessment.</td></tr><tr><td>Document Type</td><td>Separate document.</td><td>Often a section within the test plan.</td></tr><tr><td>Definition Level</td><td>Project-specific.</td><td>Defined at an organizational level.</td></tr><tr><td>Source Document</td><td>Software Requirement Specification (SRS).</td><td>Business Requirement Specification (BRS).</td></tr><tr><td>Prepared by</td><td>Test Leads or Managers.</td><td>Project Managers or Business Analysts.</td></tr><tr><td>Development Stage</td><td>Developed after requirement sign-off.</td><td>Created before the test plan is finalized.</td></tr></tbody></table></figure>



<h2 id="h-wrapping-up">Wrapping Up</h2>



When it comes to segregating test strategy from test plan, many find it quite complicated to identify the key differences between the two. A test strategy is generally a static document, while a test plan, on the other hand, specifies what to test, when to test, and how to test.



As described in the blog above, these are two different aspects wherein a test plan is comprehensive and detailed compared to a test strategy. Test plans are used at project levels, whereas test strategies are generally used at the organizational levels.

<h3 id="h-what-is-the-major-difference-between-a-test-strategy-and-a-test-plan">What is the major difference between a test strategy and a test plan?</h3>



The following is the primary distinction between a test strategy and a test plan: A test strategy is a high-level document that specifies the overall testing approach and objectives. It describes the scope, test levels, test kinds, and essential resources, with an emphasis on the overall aspects of testing. 



A test plan is a detailed document that covers the precise activities, tasks, and testing schedules. It includes a test execution plan that includes test objectives, test cases, test data, test environment, and test deliverables.

<h3 id="what-is-a-test-case"><a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">What is a Test case?&nbsp;</a></h3>



A test case is a document that describes the steps, conditions, and expected results for verifying the functionality of a certain feature or component in a software application. It basically acts as a blueprint for how testing should be carried out to ensure that the software meets the specified requirements.



Example of <a href="https://testsigma.com/blog/test-cases-for-login-page/" target="_blank" rel="noreferrer noopener">Test cases for Login</a>



<h3 id="what-is-a-test-scenario"><a href="https://testsigma.com/guides/test-scenario/" target="_blank" rel="noreferrer noopener">What is a Test Scenario?</a></h3>



Test scenarios are high-level descriptions of use cases for the software, or real-world situations. They describe—in general terms how the software will be used and help to identify the functions under test.



<h2 id="key-differences-between-test-case-and-test-scenario">Key Differences Between Test Case and Test Scenario</h2>



Here is a table that explains you simple:

<h2 id="test-case-and-test-scenario-role-in-test-automation">Test Case and Test Scenario &#8211; Role in Test Automation&nbsp;</h2>



Though distinct, Test Case and Test Scenario are very closely interrelated in their role with test automation:



Test Scenario: In <a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">test automation</a>, a test scenario is defined as a high-level testing goal or user flow.&nbsp;



For example, &#8220;Verify that a user can complete the checkout process.&#8221; It outlines what needs to be tested. Scenarios help identify what high-level functionalities or business processes are in need of automation. They drive the overall strategy and planning of automated tests by focusing on end-to-end functionality.&nbsp;



They guide the overall strategy and planning of automated tests by focusing on end-to-end functionality. Their main goal is to ensure that all the requirements for a specific real-time application have been fulfilled.



Test Case: A test case is a detailed, specific set of steps with their inputs and expected results when executing automated tests.&nbsp;



For example, in the checkout process scenario, a test case could be &#8220;Add items to the cart,&#8221; &#8220;Proceed to checkout,&#8221; &#8220;Enter payment details,&#8221; and &#8220;Confirm purchase.&#8221; Test cases are what actual automation scripts are made of, executing these detailed steps. They validate (or ensure) that everything works within a feature.

Manual Testing vs Automation Testing: Which One Should You Choose?

An application can broadly be divided into two categories: frontend and backend. Before releasing a product in the market, it&#8217;s essential to test whether both the frontend and backend of the application are working correctly. Frontend testing is the testing of the user interface visible to the user by which users interact with the application. In contrast, backend testing is about testing the actual database and server logic under the hood, which is not visible to the application users.



In this article, you will learn about fronted and backend testing and the difference between both tests. You will also learn about the various tools and techniques used in frontend and backend testing.

<h3 id="bb0sh"><a href="https://testsigma.com/blog/front-end-testing/" target="_blank" rel="noreferrer noopener">What is Frontend Testing?</a></h3>



The frontend of an application is the visual appearance and user interface that users see and use to interact with the application&#8217;s features and functionality. In the testing life cycle, frontend testing is the process of testing the frontend side of the application to ensure there are no any glitch, functionality breaks, or significant problems present in the application.



A well-driven frontend testing makes your product bug free and ensures the user will get a great user experience.<gwmw style="display: none; background-color: transparent;">

<h2 id="9ns2c">Summary</h2>



To ensure an application’s overall functionality of an application, it’s important to test both the backend and frontend sides of an application. Frontend testing ensures that an application’s overall functionality works as intended in all operating systems and browser combinations. Whereas backed testing ensures the database side of the application is working properly.

Bug Report Template | A Step-by-Step Guide to Reporting Issues in Software

Data is the new asset for any business use case for drawing insights. Similarly, Automation Testing is the new standard that tech companies set for testing their software products.



XPath plays a vital role in any of the uses above, in scraping data from multiple websites or testing products and functionality. XPath allows testers like us to navigate around various locators of the web page with the help of numerous properties such as ID, Tag Name, Group Index, and Predicates.



This blog post walks you through various examples of XPath locators and their definitions.



We have shown the Java implementation of the XPath locator in our cheat sheet for Selenium locators. Let&#8217;s begin with this comprehensive XPath cheat sheet, which will be quite helpful while performing <a href="https://testsigma.com/automated-testing">automated testing</a> or scraping data through Selenium.

<h2 id="a9l6r">What is XPath?</h2>



XPath is the path of elements on the HTML tree. XPath allows us to use different selectors on the HTML page.



We represent the current webpage in XPath by using(.) and (/) to represent child elements to navigate through different elements in HTML and XML documents.



<h2 id="an6t2">The XPath Syntax</h2>



Since we’ve discussed XPath, let’s check how we can generate XPath. The example below shows XPath syntax with single and multiple attributes.



XPath Syntax for Single Attribute



<pre class="wp-block-preformatted">//tag[@AttributeName = ‘Attribute Value’]</pre>



XPath Syntax for Multiple Attributes



<pre class="wp-block-preformatted">//tag[@AttributeName1=’Attribute Value’ and @AttributeName2=’AttributeValue2’]</pre>



<pre class="wp-block-preformatted">//tag[@AttributeName1=’Attribute Value’ or @AttributeName2=’AttributeValue2’]</pre>



<h2 id="5jra6">Different types of XPath in Selenium</h2>



XPath allows us to navigate through the webpage in two different types:



<ol type="1"><li>Absolute XPath</li><li>Relative XPath</li></ol>



<h3 id="ah60n">Absolute XPath</h3>



This locator uses the whole expression from the parent tag and starts with a single tag representing child elements.



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/image21_f18e3ccf352df315c83ba66d2d308d79_800.jpeg_1748948933.jpg" alt="Testsigma - XPath"/></figure>



Below attached is one more example of using a selector with multiple divisions. In such cases, we can use the index in the path. We define the array index inside the bracket according to the node position.



Example:



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/image41_683ed70a11a138af40f1613fc6159b9e_800.png_1748948934.png" alt="Testsigma - XPath"/></figure>



<h3 id="cgcr0">Relative XPath</h3>



Relative XPath can start from anywhere from the HTML structure. We use Relative XPath when we don’t want to write the complete XPath expression from the root node.



The Relative XPath starts from a double forward slash, whereas the Absolute XPath starts from a single slash.



Example:



In the below example, we are choosing the image selector. Unlike Absolute XPath, we need not start from HTML.



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/image51_a4abbc3843692c896c7e258429f40666_800.jpeg_1748948936.jpg" alt="Testsigma - XPath"/></figure>



<h2 id="3v3qt">XPath Expressions in Selenium</h2>



XPath expressions navigate and select appropriate elements in HTML and XML documents.



<figure class="wp-block-table"><table style="border: 1px solid black;border-collapse: collapse;"><tbody><tr style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;"><td style="border: 1px solid black; padding: 10px;

 border-collapse: collapse;">/</td><td style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;">The single forward slash is used for selecting the child element,to create absolute XPath, to select elements from the root node, and to traverse through child elements from the parent node.</td></tr><tr style="border: 1px solid black; padding: 10px;

 border-collapse: collapse;">//</td><td style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;">The double forward slash symbol is used for the descendant child(child,grandchild,etc.)in relative paths to select any elements present in the document.</td></tr><tr style="border: 1px solid black; padding: 10px;

 border-collapse: collapse;">.</td><td style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;">The single dot selects the current node.</td></tr><tr style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;"><td style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;">@</td><td style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;">Select attributes</td></tr><tr style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;"><td style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;">//a/..</td><td style="border: 1px solid black; padding: 10px;
 border-collapse: collapse;">Backward traversing is where we use (.) dot notations to go up the tree or reach the parent node.The expression attached will get the parent element of the anchor tag.</td></tr></tbody></table></figure>



<h2 id="2uro4">XPath Selectors in Selenium</h2>



XPath selectors allow us to select a specific part of HTML documents.



<h3 id="geni">Descendant Selectors</h3>



To select child elements of the current parent node, Descendant selectors are used. We use a double forward slash or single forward slash to select the child or grand-child elements in the HTML.



The Syntax for Descendant selectors:



<pre class="wp-block-preformatted">/tag or //tag</pre>



<h3 id="61apm">Attribute selectors</h3>



Attribute selectors are used for elements based on the attribute present in a single HTML node.



The Syntax for Attribute selectors:



<pre class="wp-block-preformatted">//tag[@AttibuteName= ‘Attribute Value”]</pre>



XPath by Group Index



XPath by Group Index is used to match a single element. We write the index inside the bracket and the elements outside the block element.



It executes the XPath inside the brackets and stores the matching elements in the XPath array. Then, it will identify the elements based on the index from the elements mentioned outside the bracket.



Example: If we follow the XPath by Group index, we can get a single result of our Choice.



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/image11_371c5e1a0c201202c5190835f8a81db5_800.jpg_1748948939.jpg" alt="Testsigma - XPath"/></figure>



<h2 id="3tsg7">Axes in XPath</h2>



Axes represent the relationship between the current element and its relative element. It could be anything, such as a child or sibling, parent nodes etc.



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/AttributeSelectors_e6a2e96fcf9ba933ef65e84902ea3668_800.png_1748948937.png" alt="Testsigma - XPath"/></figure>



<h2 id="cnc5">Functions in XPath</h2>



A set of operations can be used for making Functions in XPath. It could be adding two HTML or getting the count of images present in a webpage.



Node Functions



XPath has several node functions such as name(), text(), position(), last(), comment() and name(). This Function provides the name of the HTML node.



<pre class="wp-block-preformatted">Xpath=//[starts-with(name(), ‘h’)]</pre>



text()



This function is used to locate the HTML elements based on the text of the web element.



<pre class="wp-block-preformatted">Xpath=//td[text()='login']</pre>



comment()



This function selects the elements with comments.



<pre class="wp-block-preformatted">/span/comment()</pre>



last()



This function selects the last element in the current Node.



<pre class="wp-block-preformatted">/span/img[last()]</pre>



position()



This function provides the position of the element.



<pre class="wp-block-preformatted">Ex: (//a)[position() ≤= n]</pre>



<h2 id="cuhf3">Operators in XPath</h2>



We can use operators combined with XPath to check certain conditions and verify requirements. It behaves like the if-else condition. XPath predicates come in square brackets after the parent elements are tested. With the following attached XML below, we’ve provided different examples for the operator:



<ul><li>Greater than(&gt;)</li><li>Less than(&lt;)</li><li>OR operator ( OR )</li><li>AND operator ( AND )</li><li>Not Equal to ( != )</li><li>Equal to ( = )</li></ul>



<pre class="wp-block-preformatted">&lt;eCommerce&gt; &lt;mobile&gt; &lt;Iphone supplier="mother" id="1"&gt; &lt;year&gt;2020&lt;/year&gt; &lt;amount&gt;1000&lt;/amount&gt; &lt;store&gt;ABC&lt;/store&gt; &lt;/Iphone&gt; &lt;Samsung supplier="store" id="2"&gt; &lt;year&gt;2018&lt;/year&gt; &lt;amount&gt;700&lt;/amount&gt; &lt;amount&gt;700&lt;/amount&gt; &lt;store&gt;XYZ&lt;/store&gt; &lt;/Samsung&gt; &lt;/mobile&gt; &lt;/eCommerce&gt;</pre>



Less than operator ( &lt; )



We can use this operator with XPath to check if the result is less than the number



Example:



<pre class="wp-block-preformatted">eCommerce/mobile/iphone[year &lt; 2019]</pre>



Result: In this expression, all the phones are listed with a year Lesser than 2019.



Greater than operator ( &gt; )



We can use this operator with XPath to check if the result is greater than a number.



Example:



<pre class="wp-block-preformatted">eCommerce/mobile/iphone[year &gt; 2019]</pre>



Result: In this expression, all the phones are listed with a year greater than 2019.



Equal to operator ( = )



We can use this operator for comparing or checking if the value is equal to the expected value.



Example:



<pre class="wp-block-preformatted">eCommerce//[@store=’ABC’]</pre>



Result: In this expression, all the stores with the name ABC are listed. Thus, the result will be an iPhone.



Not Equal to operator ( != )



We can use this operator to check if the operator is not equal to the expected value



Example:



<pre class="wp-block-preformatted">eCommerce//[@store!=’ABC’]</pre>



Result: In this, we will have all stores not named ABC. The result will be Samsung.



AND operator ( and )



We use this operator in cases where we want both conditions to be true.



<pre class="wp-block-preformatted">eCommerce//[@store=’ABC and @store=’XYZ’’]</pre>



OR operator ( or )



We use this operator in cases where we want any one of the conditions to be true.



<pre class="wp-block-preformatted">eCommerce//[@store=’ABC or @store=’XYZ’’]</pre>



<pre class="wp-block-preformatted">//input[@value=’A’ or @value=’B’]</pre>



<h2 id="eamk2">Browser console to locate XPath</h2>



We can test our XPath in browsers before checking it programmatically. With the help of debugging tools such as a console, we can test our XPath in the console.



We can write our XPath or with help of an inspector, we can get the XPath of any element on the webpage.



To validate XPath programmatically, follow these steps:



<ol type="1"><li>Visit any website (for example, Testsigma) and press F12 on the keyboard.</li><li>Click on the console as shown in the image below.</li><li>$x(&#8220;//img[@class=&#8217;img-responsive&#8217;]/@src&#8221;)</li><li>Entering the above XPath, we can select the Testsigma logo element on the left top corner as shown in the below image.</li></ol>



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/Testigma_72645294d8e4483227a806635149da97_800.png_1748948932.png" alt="Testsigma - XPath"/></figure>



Validating XPath with help of inspector XPath:



<ol type="1"><li>Visit any website and press F12 on the keyboard.</li><li>Click on Elements and right click element of your choice</li><li>Hover the cursor over Copy and select Copy full XPath.</li></ol>



Once done we can place the copied XPath inside the $x(`place your XPath copied from elements`) and check your results.



<h2 id="bfbuv">Wrapping Up</h2>



XPath is used to select or find elements on a webpage. We can use XPath in combination with other programming languages as well.



XPath allows us to navigate through the webpage in two different types:



<ol type="1"><li>Absolute XPath.</li><li>Relative XPath.</li></ol>



Relative XPath is more reliable and efficient while testing or scrapping a webpage. Since it supports dynamic operations, we can continue to extract data or automate tasks using the same code, even if the website is updated.



<h2 id="ffu0t">Frequently Asked Questions:</h2>



<h3 id="64mh2">What is the easiest way to find XPath?</h3>



The easiest way to find XPath is by using browser developer tools. Follow the below steps to generate XPath quickly.



<ol type="1"><li>Right-click on the element of your choice and select inspect; this will launch the inspector tool for elements HTML code.</li><li>Copy the XPath by right-clicking the HTML element.</li><li>Test the copied XPath to locate the same element in Chrome.</li></ol>



<h3 id="6bbqu">Which XPath is faster in Selenium?</h3>



The Relative XPath is faster in Selenium than the Absolute XPath. Absolute XPath is slow because it starts from the root node. Relative XPath is faster and most preferred because it starts from the middle of the HTML structure.



<h3 id="dek6t">Which XPath is best?</h3>



Relative XPath is best in major scenarios as there&#8217;s minimum code maintenance required if there&#8217;s any update on the website.

<h2 id="software-inspection-vs-software-testing-overview">Software Inspection vs Software Testing &#8211; Overview</h2>



<h3 id="4tbo6">What is Software Inspection?</h3>



Software inspection refers to a peer review of software to identify bugs or defects at the early stages of SDLC. It is a formal review that ensures the documentation produced during a given stage is consistent with previous stages and conforms to preestablished rules and standards.



Software inspection involves people examining the software product to discover defects and inconsistencies. Since it doesn’t require system execution, inspection is usually done before implementation.



<h3 id="f62kk">What is Software Testing?</h3>



Software testing refers to verifying and <a href="https://recruitcrm.io/blogs/questions-to-ask-while-evaluating-applicant-tracking-system/" target="_blank" rel="noopener">evaluating</a> that software does what it is expected to do. It is done to discover bugs, <a href="https://testsigma.com/blog/software-testing-errors-to-look-out-for-with-examples/">errors</a> or defects before the software is used.



When you test a software product or application, you execute a program using artificial data and verify the results of the test run for errors, variations, or information about the program&#8217;s non-functional attributes.



Software Testing enables teams to identify and resolve potential problems before they affect actual users. The QA professionals must test the software with a proper <a href="https://testsigma.com/blog/software-testing-strategy/">Software Testing strategy</a> to ensure the software’s performance, efficiency, and reliability.



Software Testing is part of a more general verification and validation process. It reveals the presence of errors, not their absence.



<h2 id="software-inspection-vs-software-testing-detailed-comparison">Software Inspection vs Software Testing &#8211; Detailed Comparison</h2>



<h3 id="f2b5v">What is the purpose of software inspection?</h3>



Software inspection aims to identify software defects and deviations, ensuring the product meets customer requirements, wants, and needs. In a broader context, the objective of the inspection is to inhibit defective software from flowing down the subsequent operations, thereby preventing loss to the company.



Software inspection is designed to unravel defects or bugs, unlike testing, which is done to make corrections. It is divided into two types:



<ul><li>Document inspection: Here, the documents produced for a given phase are inspected, further focusing on their quality, correctness, and relevance.</li><li>Code inspection: The code, program source files, and test scenarios are inspected and reviewed.</li></ul>



<h3 id="84k44">Who are the key parties involved in Software Inspection?</h3>



<ul><li>Moderator: A facilitator who organizes and reports on inspection.</li><li>Author: A person who produces the report.</li><li>Reader: A person who guides the examination of software; more of a paraphraser.</li><li>Recorder: An inspector who logs all the defects on the defect list.</li><li>Inspector: The inspection team member responsible for identifying the defects.</li></ul>



<h3 id="9o8uk">What is the software inspection process?</h3>



Software inspection involves six steps – Planning, Overview, Preparation, Meeting, Rework, and Follow-up.



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/in-article-33_ca5b036bf79da572a00db450c247de72_800.jpg_1748948678.jpg" alt="What is the software inspection process?" /></figure>



Planning



The planning phase starts with the selection of a group review team. A moderator plans the activities performed during the inspection and verifies that the software entry criteria are met.



Overview



The overview phase intends to disseminate information regarding the background of the product under review. Here, a <a href="https://www.visme.co/presentation-maker/" target="_blank" rel="noreferrer noopener">presentation</a> is given to the inspector with some background information needed to review the software product properly.



Preparation



In the individual preparation phase, the inspector collects all the materials needed for inspection. Each reviewer studies the project individually and notes the issues they encounter.



Meeting



The moderator conducts the meeting to collect and review defects. Here, the reader reads through the product line by line while the inspector points out the flaws. All issues are raised, and suggestions may be recorded.



Rework



Based on meeting notes, the author changes the work product.



Follow-up



In the last phase, the moderator verifies if necessary changes are made to the software product, compiling a defect summary report.



<h3 id="3ltqd">What is the purpose of software testing?</h3>



The purpose of software testing is to identify errors, disparities, or missing requirements contrary to actual requirements.



Software testing identifies bugs and defects in the development process so they&#8217;re repaired before the launch. This is done to ensure that only quality products reach consumers, ensuring customer satisfaction.



<h3 id="9utl6">What is the software testing process?</h3>



Software testing is a process rather than a single activity. Let’s look at the components that make up the whole.



Requirements Analysis



The first step requires the QA team to comprehend the software requirements. They meet different organizations, stakeholders, teams, etc. Once the requirements are understood, the next step is identifying the components or parts of software that ought to be tested.



Test Planning



This stage involves the team planning the strategy and approach. Typically, the test manager carries out this activity to look after certain factors such as how much effort testing requires how much testing costs, and which types of testing to do.



Test Case Designing



The team develops the test case based on specific criteria and scope. Once the test planning is done, the development of test cases begins. Here, the testing team designs the test cases for execution, which are then delivered to the QA team for an examination.



Test Environment Setup



This means setting up all software and hardware resources for the testing team to execute all the test cases. Simply put, this stage decides the conditions on which the software is tested.



Test Execution



The testing team now executes tests based on test planning and marks the test report. If the test case is successfully completed, it is marked as passed. If the test case is failed, it is marked as failed, and the corresponding defect or error is reported to the development team. If the test case is blocked due to a mistake, it is marked as blocked.



Test Closure



This phase ensures the completion of test execution. Several activities are undertaken, such as test completion reporting, collection of test completion matrices, and test results. Once this cycle is completed, the test cycle closure report is prepared.



<h2 id="ec0dg">SDLC without Inspection</h2>



Imagine a software development life cycle without inspection. What possibly could go wrong? Aren’t we testing our software to detect defects?



Usually, we assume that defects or bugs are related to code only, which can be identified by testing! Does that mean there are no other defects? Well, that’s not true.



Defects can occur before coding even starts. Such defects can originate in all stages due to inaccurate specifications, insufficient requirements, or incorrect feature implementation.



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/In-article-35_48d6f05fa91f7cdbd2c5aaca3c75dc21_800.jpg_1748948679.jpg" alt="SDLC without Inspection" /></figure>



As shown above, defects in the previous stages of SDLC get identified in the maintenance stage, which adds stress to the maintenance stage.



This increases costs and time to repair or resolve defects, leading to late delivery, low production, and longer release cycles.



<h2 id="35d0c">SDLC with Inspection</h2>



Imagine where defects found in each stage get removed or fixed before moving on to the next phase. Great, isn’t it? That’s what inspection helps you with.



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/In-article-34_9699058c243c2cb6134d27d984e17d5a_800.jpg_1748948681.jpg" alt="SDLC with Inspection" /></figure>



When inspections are incorporated and applied, they save us from chaos zone and minimize the cost of solving defects. This leads to increased production and shorter release cycles, ensuring software quality.



<h2 id="6ak5b">Key Differences between Software Inspection and Software Testing</h2>



Software inspection involves examining a product to ensure it complies with the end user’s requirements and specifications. In contrast, software testing tests the product to ensure it does what it is supposed to do and is ready to be used by consumers.



To understand the underlying difference between the two, we have listed the types of errors identified by both processes:

<h2 id="9grd2">Conclusion</h2>



In software engineering, quality is the primary focus of any project. As evident, software testing and inspection are two different steps that are carried out when ensuring the overall quality of a product.



However, these processes are not mutually exclusive. Instead, they complement each other, so you shouldn’t ignore one in favor of the other.



<h2 id="b8b3o">Frequently Asked Questions</h2>



<h3 id="9kvlg">What are the similarities between software testing and inspection?</h3>



Both testing and inspection are integral in ensuring that not only is your software of the highest quality, but it also meets customer requirements. Simply put, both processes help detect and prevent quality issues and defects before the product is released to the consumer market.



<h3 id="388do">Why is software inspection more important than testing?</h3>



Software inspection is more involved than testing as it covers a broader context regarding ensuring software quality.



Software testing is the process of evaluating the product and whether it works appropriately per specifications/requirements. Software inspection is testing plus code review to ensure that it is correct, optimized, and maintainable. Simply put, the goal of the inspection is to remove errors and reduce the cost of rework.

Software Inspection v Software Testing: How do they differ? cover

Software Inspection vs Software Testing: How do they differ?

Several testing procedures and techniques find flaws throughout the Software Testing Life Cycle, abbreviated STLC. Defect leakage measures the percentage of problems that leak from one testing stage to the next, demonstrating the efficacy of testing. However, because certain defects, faults, and mistakes are present at the most internal level of the program, even the most well-known and efficient testing processes cannot locate and identify them all.&nbsp;



Leakage is found in the later phases of the software testing life cycle (STLC). Proficient software engineers, therefore, use a method known as defect leakage in software testing to calculate the total number of undetected errors in software systems. This method also helps them validate their testing efforts by allowing them to determine the total number of faults present in a software program.



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/MfpG7dtDvbEnIvO5fsn1CvzIGY-PPDviHW_MdWkxxujyB6MmNEk-znIGCjLUPpWb9y9sFkugBvWcT1sboRZeS7M5Ty2_cAqtBwpEYvY9HZNUfNRzK9CqpdBWLgfs2pdBuON3wzVDrok9S54MwqTnVPnTj1TNHAjGhsz7tNY26bmP2xq00Q-litHb_w_1748948237.png" alt="Defect Leakage in Software Testing"/></figure>







Defect leakage is the metric that confirms the significance of the QA testing procedure. It considers the number of problems found throughout the ongoing process. In the brief term, it is a type of defect that, when put into use, surpasses all team tests and leads to a product that instantaneously affects users.



With a compound annual growth rate (CAGR) of 6.1%, the global market for leak detection and repairs is anticipated to increase from <a href="https://www.businesswire.com/news/home/20220819005138/en/Leak-Detection-and-Repair-Global-Market-Report-2022---ResearchAndMarkets.com" target="_blank" rel="noreferrer noopener nofollow">$14.63 billion in 2021 to $15.52 billion in 2022</a>. At a CAGR of 7.2%, the leak detection and repair market is predicted to reach $20.5 billion in 2026.

<h2 id="h-a-quick-overview-of-defect-leakage">A Quick Overview of Defect Leakage</h2>



Software engineers use a method called &#8220;Defect Leakage&#8221; to determine the total extent of mistakes and flaws that go unnoticed to decide on the overall number of faults in the software application. This further helps them validate their test coverage.&nbsp;



It is the ratio of faults attributable to a step but only discovered in later phases compared to the total of defects found in that step plus all defects discovered attributable to a step but only discovered in the last stages. Additional elements of defect leaking include:



<ul><li>Following the delivery of the application, it happens at the end-user or customer end.</li><li>They are used to calculate the defect leakage rate for subsequent.</li><li>It may be computed at the initial level, the overall project level, or both.</li><li>It is expressed as a percentage.</li></ul>



<h2 id="h-testing-error-in-software">Testing Error in Software</h2>



A software application bug is a variance or diversion from the intended user&#8217;s needs or the initial business needs. A software bug results in inaccurate or unexpected outcomes from a software program that doesn&#8217;t adhere to the specifications as intended. While running the test cases, testers could encounter such flaws.



These two names are similar and are sometimes used indiscriminately by testing teams because both represent defects that need to be rectified in the business.



Testers can encounter test findings contrary to what was anticipated when they run the test cases. A software defect is known as this variation in test findings.



<h2 id="h-how-to-determine-defect-leakage">How to determine defect leakage</h2>



<figure class="wp-block-image"><img src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/r1iE1ZkREQVBsEKDIMnfvRv7CoIw9VXOGpEgJT92J-q6uRCkuwZr6E4KuyMA_ZuPQiJNxqLGrZBAI0cG4AKLAACHyfpoTvbCLB1D78_dmK6fCQY0I8XlbBT5I-aMhF0SrkShp4h-w1CCzpOZKESmFNk5fLMhy4bqCRF5BIBSlkJuhJ1PHA2_TL7Dvw_1748948239.png" alt="How to determine defect leakage"/></figure>







Defect leakage in software testing is a measurement that assesses the proportion of bugs that pass from one testing stage to the next while also demonstrating the efficacy of software testers&#8217; testing. The value of the test team is shown only, though, when there is little to no fault leaking.



This formula is used to determine the defect leakage rate: #Defect discovered during next phase/(# Defects found during testing + #Defects found during next phase) * 100



For instance, end users found 42 faults at the UAT manufacturing unit, while 140 defects were found during the whole quality process, comprising both the testing facility and the production site. Defect leakage would thus be as follows:



= (42/140) * 100



= 30%



Therefore, 30% is the defect leakage percentage.



Maintain a record of the location of the defect and make repairs before it is released, check the development process, and keep a reasonable defect with an efficient repair.



Along with discovery and repair, software fault disclosure is also crucial. Additionally, for solutions and validation, transparency concerning software flaws is vital.

Since software development involves several different activities, there are many possibilities as to why a defect could go unnoticed despite extensive testing. The causes of defect leaking might range from a minor mistake in the software&#8217;s coding or scripting to a lack of product or industry understanding. Therefore, a few of these causes, which might result in excessive defect leakage, are listed here.



<ol><li>Communication issues: Defects may go undetected and unreported if there is poor or absent communication during the software development process (from requirement collection to interpretation/documentation or stage).</li><li>Human error: Since people make mistakes, it would be absurd to expect the items they create to be perfect and free of flaws. That explains how software flaws and defects might appear. However, notwithstanding the probability of human-caused errors, humans still manage to produce goods that are superior to those made by any non-human entity. Therefore, we must rely on human intelligence and thus run the danger of mistakes unless we find one that can perform the task better than humans.</li><li>Unachievable deployment timelines: Scarce or limited resources and due dates are among the problems that software developers frequently have to deal with. They may have to make some sacrifices as a result (such as not allocating enough time for designing and not validating their code before delivering it to the quality assurance team), which can raise the likelihood of faults and errors.</li><li>Faulty design logic: Finding a dependable solution requires both R&amp;D and some level of conceptualizing as software applications become complex. However, a strong desire to do the project quickly, lousy use of expertise (i.e., products, components, processes), and poor knowledge of technological viability before creating the architecture are all factors that might cause errors or bugs to appear.</li><li>Poor coding: This includes bad coding techniques like unhandled failures, missing deviations, and incorrect input validations, as well as the use of inadequate tools (like poor compilers, debugging tools, and validators that some software developers are using). All of these can introduce bugs in the code that may be difficult to troubleshoot. Sometimes, problems in the code may be the result of poor programming.</li><li>Not using version control: Examine the version monitoring system (if there is one). If the tester experiences frequent regression errors, trace every change made to a collection of code bases using parallel version systems.</li><li>Defects in third-party tools: During software creation, third-party tools like debuggers, HTML builders, shared DLLs, and add-ons/plug-ins (such as shopping cart connectors and map navigator APIs) are frequently required. However, these third-party tools may have defects that get transferred to the product.</li><li>Lack of experienced testing: Subpar testing is frequently the norm in many companies. This could involve a shortage of skilled testers, flaws in the testing procedure, testing treated carelessly, and the method is carried out without consideration. All of these have the potential to lead to software flaws and failures.</li><li>Excessive reliance on automation testing could result in a manual tester missing a bug or fault since automated testing lacks human perception and experience.</li></ol>



<h2 id="h-strategies-to-control-defect-leakage">Strategies to Control Defect Leakage</h2>



Software engineers are engaged in an ongoing conflict that will never be ultimately won. Defects do occur. As a result of deadlines or constraints, software engineers may even intentionally add flaws to their products. However, how can unwanted vulnerabilities that make the application challenging to use and damage reputation be fixed?



As the project&#8217;s relevance rises, more effort should be spent managing production-site issues. Defects may be significantly reduced by using sound test recording, reporting, customer interaction, and product openness. Even the most significant log in the world is partly useless if the flaws are not corrected.



Program developers and testers must employ several approaches to avoid defect leakage, guarantee that it is managed and does not remain in the software, and certify the quality of the finished output. This reduces their overall engineering and testing resources and enables them to prevent any significant problems during the software development cycle. So, the following are some methods to stop excessive defect leakage in software testing:



<ul><li>Pick a locus, then do extensive testing and analysis.</li><li>Create a simple, concise report that may be utilized in interactions with and among the business and corporate leadership to assess the general health of a quest application quickly.</li><li>Automatically record production-related flaws. This method might get complicated very fast, so have a separate area to document faults and add pertinent concerns.</li><li>Set up a small SWAT squad or fast reaction team that can respond rapidly to crises if the group is large enough or the project is vital enough.</li><li>Additionally, as a general rule, each developer should be attentive to the state of their product, actively involved, and accountable for their code.</li><li>Look for components susceptible to significant defect leakage and critical content and locations.</li><li>Test the product thoroughly on the minor components before using a real-world simulation.</li><li>If issues are terrible, think about rewriting them and look more closely at the entire system.</li></ul>



A suitable fault extraction efficiency and maintaining track of problems discovered and fixed before release are indicators of healthy software development. Keeping track of any issues found after deployment and reporting them to the product, engineering, and quality teams are vital so that test cases can be upgraded and procedures may be changed as needed. Since most consumers want to understand taking responsibility for the issues and striving to find solutions, visibility concerning software errors is just as crucial as discovery and correction.



<h2 id="h-steps-to-fix-the-defects">Steps to fix the defects:</h2>



Software engineers and QA testers can resolve the issues by following the instructions below.



<ul><li>Assign to someone: The task is delegated to a developer or specialist, and the status is changed to responding.</li><li>Setting the schedule: This step is handled by the development side. They will design a timeline to resolve these issues depending on the fault priority.</li><li>Repair the bug: While the project team resolves the flaws, the Testing Team monitors the procedure and compares it to the timetable.</li><li>Submit the solution: When bugs are fixed, request a resolution report from the developers.</li></ul>



<h2 id="h-validation">Validation :</h2>



The testing team confirms that the flaws are rectified after the design team fixes and documents the problem.



For instance, in the situation above, once the development team reports they have addressed 71 flaws, the team needs to retest to see whether these bugs have been resolved.&nbsp;



A defect is converted to closed status after it has been fixed and validated. If not, then the team notify devs to recheck the fault and consider the following:



<ul><li>Appropriately calculate the defect percentage.</li><li>Calculate the overall project and phase levels.</li><li>Openness for the product.</li><li>Reliable test logging.</li><li>Include engagement from the client.</li></ul>
