<h2 id="h-what-is-test-completion">What is Test Completion?</h2>



Test completion is the last step in the software testing life cycle, where we finalize all testing activities and document the results. Our main goal is to ensure the software product is ready for production release.&nbsp;



The activities involved in test completion can vary depending on the project but typically include the following:&nbsp;



<ul><li>Verifying that all test cases have been executed&nbsp;</li><li>Analyzing the test results and identifying any defects</li><li>Prioritizing and fixing defects&nbsp;</li><li>Generating a test completion report&nbsp;</li><li>Communicating the test results to stakeholders&nbsp;</li></ul>



The test completion report is a document that summarizes the results of the testing activities.&nbsp;



<h3 id="h-what-is-the-purpose-of-test-completion">What is the purpose of Test Completion?</h3>



A clear sense of purpose is essential to success in any endeavor. When it comes to testing a software product, we must ensure we&#8217;ve done everything possible to ensure it&#8217;s ready for release. That&#8217;s where test completion criteria come in &#8211; the specific conditions we need to meet before stopping testing.&nbsp;



Things like&nbsp;



<ul><li>how many test cases we&#8217;ve run,&nbsp;</li><li>how much of the code we&#8217;ve covered,&nbsp;</li><li>how many bugs we&#8217;ve found and fixed, and&nbsp;</li><li>how risky the product is in determining when we&#8217;re done testing.&nbsp;</li></ul>



It&#8217;s essential to have these measures defined in the test plan and agreed upon by everyone involved so that we&#8217;re all on the same page and can work efficiently.



<h2 id="h-what-are-the-test-completion-work-products">What are the Test Completion Work Products?</h2>



The work products of the test completion phase are the following:



<ul><li><a href="https://testsigma.com/blog/test-summary-report/" target="_blank" rel="noreferrer noopener">Test summary report</a>: This report summarizes the testing efforts carried out during the testing process. It provides information on the amount of testing that was done, the defects that were found, and the risks that were identified. The test summary report is an essential input for stakeholders who need to make decisions about the software, such as whether to release it to production.</li><li>Defer requests or product backlog objects: If defects cannot be fixed in the current release, they are added to the product backlog as change requests. In some cases, the requirements may not specify defects or functionalities. These are also added to the product backlog as change requests.</li><li>Action items for progress: The test completion phase is also an opportunity to identify lessons learned and recommend modification. These action items should be documented and implemented in future projects.</li><li>Completed testware: All relevant test work products and documents, such as test cases, test results, and test plans, are completed and archived in this phase. This ensures that the test results are preserved and can be used for future reference.</li></ul>



<h2 id="h-when-do-test-completion-activities-occur">When do Test Completion Activities Occur?</h2>



A few times during a project, we celebrate our progress and completion. These moments <a href="https://www.teamly.com/blog/project-milestones-examples/" target="_blank" rel="noreferrer noopener">are called project milestones</a>, and they&#8217;re a chance for us to cheer each other on and take a breather before diving into the next phase.



Below are some instances when test completion activities occur:



<ul><li>When a software system is all ready to go live&nbsp;</li><li>When we finish up a testing project (or decide to take a break)&nbsp;</li><li>When we complete a round of an Agile project&nbsp;</li><li>When we finish up a whole level of testing&nbsp;</li><li>When we&#8217;ve assembled a maintenance release. Woohoo!</li></ul>



<h2 id="h-major-activities-of-test-completion">Major Activities of Test Completion</h2>



Completing a test is a fun and exciting process that involves several essential activities!&nbsp;



First, we ensure all the reported defects have been addressed and closed. If there are any open defects, we create change requests or product backlog items to ensure they are handled. We also close out any incident reports and document our acceptance of the system.&nbsp;



Next, we create a test summary report that gives a broad overview of all the testing we completed and the results we found. We share this report with our stakeholders so they can see all our hard work! Before we wrap things up, we finalize and archive all our test materials to be used again. We also transfer any relevant information to maintenance teams or other stakeholders who may find it useful.&nbsp;



Finally, we take the time to analyze what we learned during the testing process so we can improve and grow in the future. We want to ensure we&#8217;re constantly enhancing and improving what we do!



Here are some&nbsp;examples for the significant test activities completion:



<ul><li>Checking whether all defect reports are closed.</li><li>Entering change requests or product backlog items for any defects that remain open.</li><li>Closing incident reports.</li><li>Documenting the system&#8217;s acceptance.</li><li>Finalizing and archiving the test environment, the test data, the test infrastructure, and other testware for later reuse.</li><li>Handing over the testware to the maintenance teams, other project teams, or other stakeholders who could benefit from its use.</li><li>Checking which planned deliverables have been delivered.</li><li>Analyzing lessons learned from the completed test activities to determine changes needed for future iterations, releases, and projects.</li><li>Using the information gathered to improve test process maturity.</li></ul>



<h2 id="h-what-is-the-test-completion-criterion">What is the Test Completion Criterion?</h2>

<h2 id="h-what-is-an-isolation-testing">What is an Isolation Testing?</h2>



Isolation testing is a <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a> technique that isolates individual components or units of code from each other to test them independently. This helps to identify and fix defects early in the development process before they can cause problems in other parts of the system.



As Kent Beck, a software engineer and agile advocate, said, &#8220;The best way to find bugs is to isolate them.&#8221; This is because isolation testing can help to narrow down the scope of a defect, making it easier to find and fix.



Testing is a never-ending journey, essential for the quality of any software. By developing our knowledge of testing techniques like isolation testing, we can ensure that our software is free of defects and meets the needs of our users.



<h2 id="h-characteristics">Characteristics</h2>



The characteristics of isolation testing in more detail.



Time-consuming: Isolation testing is time-consuming because each unit or component must be tested individually. This can be especially time-consuming for large or complex systems.



Stubs and drivers: Stubs and drivers are software components used to simulate the behavior of external dependencies. This allows the unit or component being tested to be isolated from the rest of the system. Stubs provide the expected input to the unit or component, while drivers collect the output from the unit or component.



Expensive: Isolation testing can be expensive because it requires the creation of stubs and drivers. Additionally, the cost of isolation testing can increase as the size and complexity of the system increases.



Atomic in nature: Isolation testing is atomic, meaning that each unit or component is tested independently. This ensures that interactions with other code do not cause defects.



Verifies the output of each one of those interfaces/subsystems precisely: Isolation testing verifies the output of each unit or component precisely. This ensures that the unit or component is producing the expected results.



Overall, isolation testing is a valuable method to help identify defects early and improve software quality. Yet, knowing the time, cost, and other challenges associated with isolation testing is essential.



Here are some additional tips for conducting isolation testing:



<ul><li>Use a test framework to automate the testing process. This can help to save time and improve efficiency.</li><li>Use a mocking framework to create stubs and drivers. This helps simplify the testing process and improve accuracy.</li><li>Focus on testing the most critical units or components first. This will help ensure the system&#8217;s most essential parts are thoroughly tested.</li><li>Integrate isolation testing into your continuous integration (CI) pipeline. This will help ensure that tests are run frequently, and defects are detected early.</li></ul>



By following these tips, you can conduct isolation testing effectively and efficiently.



<h2 id="h-the-need-for-isolation-testing">The Need for Isolation Testing</h2>



Isolation testing is essential because it can help identify bugs more quickly, prevent bugs from being introduced into other codes, and improve software performance.&nbsp;



<ol><li>Identifying bugs more easily: When a specific application unit is tested in isolation, there are fewer variables to consider, making it easier to determine the cause of a bug. This can save time and effort in debugging.</li></ol>



<ol start="2"><li>Preventing bugs from being introduced: When a particular application unit is tested in isolation, it is less likely to interact with each other unexpectedly, which can lead to bugs. This can improve the overall quality of the software.</li></ol>



<ol start="3"><li>Improving performance: When a certain application unit is tested in isolation, it can be optimized for efficiency without worrying about how it interacts with other codes. This can improve the performance of the software.</li></ol>



<h2 id="h-isolation-testing-in-performance-testing">Isolation testing in performance testing</h2>



In performance testing, isolation testing is a technique that isolates individual system components or functionalities to evaluate their performance separately. This helps to identify performance bottlenecks, resource utilization problems, or scalability issues within specific components of a complex software system.



By isolating and testing individual elements, performance testers can optimize and fine-tune them for better overall system performance. It also helps to simulate different load conditions and stress testing on specific components to ensure they can handle their designated tasks efficiently.



For example, a performance tester might isolate the database server to test its performance under different load conditions. They might also isolate the webserver to test its performance under traffic conditions. By isolating these components, the performance tester can identify any performance bottlenecks and make necessary adjustments to improve performance.



<h2 id="h-isolation-testing-in-unit-testing">Isolation testing in unit testing</h2>



In unit testing, isolation testing is the practice of testing a single unit or module of code in isolation from the rest of the application. This involves isolating the unit under test from external dependencies, such as databases, web services, or external libraries, using mock objects or stubs.



This approach ensures that any failures or issues detected during testing are specific to the unit being tested, allowing for easier debugging and more robust code development.&nbsp;



For example, a unit tester might isolate a function to test its functionality. They might mock out the database dependency so that the function does not connect to the database. This allows the tester to focus on testing the function&#8217;s logic without worrying about the database.



<h2 id="h-test-isolation-in-end-to-end-testing">Test Isolation in End-to-End Testing​</h2>



In end-to-end testing, test isolation involves executing tests for individual user journeys or specific functionalities within a complete application workflow. By isolating these tests, testers can independently validate the behavior of specific features, user interactions, or scenarios.



This approach helps identify defects or discrepancies within specific application parts, ensuring they work correctly before testing the entire end-to-end flow. Test isolation in end-to-end testing enhances debugging efficiency and accelerates issues&#8217; identification and resolution.



For example, an end-to-end tester might isolate the login functionality to test it independently. They could create a test case that logs in a user and then verifies that the user is logged in. This allows the tester to focus on testing the login functionality without worrying about the rest of the application.



<h2 id="h-test-isolation-in-component-testing">Test Isolation in Component Testing​</h2>



In component testing, test isolation focuses on testing individual software components, such as modules, classes, or functions, in isolation from the broader system. This approach ensures that each component functions as intended and adheres to its specifications.



Test isolation in component testing is particularly valuable for verifying the correctness of the components&#8217; algorithms, logic, and data processing. It allows for comprehensive testing of each element&#8217;s functionality independently, contributing to the overall reliability and quality of the software components.



For example, a component tester might isolate a class to test its functionality. They might do this by creating a test case that calls the class&#8217;s methods and verifies that they return the expected results. This allows the tester to focus on testing the class&#8217;s functionality without worrying about the rest of the application.



<h2 id="h-advantages">Advantages</h2>



There are many advantages to isolation testing, including:



<ul><li>Early defect detection: Isolation testing can help to identify defects early in the development process before they can cause problems in other parts of the system.</li><li>Improved quality: Isolation testing can improve the software&#8217;s quality by ensuring each component works correctly.</li><li>Reduced debugging time: Isolation testing can help reduce debugging time and cost by identifying defects early on.</li><li>Improved reliability: Isolation testing can help improve the <a href="https://en.wikipedia.org/wiki/Software_reliability_testing" target="_blank" rel="noreferrer noopener">software&#8217;s reliability</a> by making it less likely to fail.</li></ul>



<h2 id="h-disadvantages">Disadvantages</h2>



There are also some disadvantages to isolation testing, including:



<ul><li>Can be time-consuming: Isolation testing can be time-consuming, especially if the software is complex.</li><li>Can be difficult to automate: Isolation testing can be challenging, making it difficult to scale.</li><li>Can give a false sense of security: Isolation testing does not test the interactions between components so it can give a false sense of security.</li></ul>

<h2 id="h-how-to-do-isolation-testing">How to do Isolation Testing?</h2>



Let us look into the steps and know how it is done:



<ol><li>Identify the component to be tested. Look at the component details &#8211; structure, the dependencies, and the risk of introducing bugs.</li><li>Create test cases. Design the test cases to test all possible scenarios for the component and all expected behaviors. This can be done using testing techniques such as unit testing, integration testing, and system testing.</li><li>Isolate the units of code. Use stubs or mocks to simulate the behavior of other units of code or external dependencies. Stubs are dummy objects that provide canned responses, while mocks are objects that can be used to verify the behavior of other objects.</li><li>Run the tests. Run the tests in a controlled environment to ensure accurate results. This can be done using a test automation framework or running the tests manually.</li><li>Analyze the results. Interpret the results of the tests to identify any bugs. Fix any bugs found, and rerun the tests to verify that the bugs have been fixed.</li><li>Repeat the process as needed. Repeat the process as needed. This may be necessary if new code is added to the system, changes to existing code, or new test cases are created.</li></ol>

<h2 id="h-frequently-asked-questions">Frequently Asked Questions</h2>



<h3 id="h-is-unit-testing-the-same-as-isolation-testing">Is unit testing the same as isolation testing?</h3>



Unit and isolation testing are both techniques that involve testing smaller system components. However, there are some key differences between the two techniques.



<ul><li>Unit testing: Unit testing is a type of white-box testing that tests individual units of code, such as functions or methods. Unit testing aims to ensure that each unit of code works as expected and does not contain any bugs.</li><li>Isolation testing: Isolation testing is black-box testing that tests a unit of code or system component in isolation from other units or components. The goal of isolation testing is to identify and isolate bugs that different system parts may cause.</li></ul>



<h3 id="h-what-is-isolation-in-testing">What is isolation in testing?</h3>



Isolation in testing means testing a component or unit of an application or a system independently of other units or components.

Isolation Testing | What it is, When & How to Do?

According to Edward A. Strollo, a professor of software engineering at Stevens Institute of Technology, &#8220;The software requirements for a product like a plane or a train are so complex that it is impossible to test the system as a whole.&#8221; And this line throws a light on how important and complex integration testing and end-to-end testing can be.



This blog post will explore the core differences between integration testing and end-to-end testing and why understanding these differences is crucial for successful software development.

<h2 id="integration-testing-vs-end-to-end-testing-overview">Integration Testing vs End to End Testing &#8211; Overview</h2>



<h3 id="h-what-is-end-to-end-testing"><a href="https://testsigma.com/end-to-end-testing" target="_blank" rel="noreferrer noopener">What is End to End Testing?</a></h3>



End-to-end testing is a software testing technique that verifies the entire software system from start to finish. It tests all the integrated components of the system to ensure that they work together as intended. End-to-end testing aims to identify any potential defects or problems that may occur when real users use the system.



This testing technique is especially important for complex software systems, where integrating different components can be complex and error-prone. By testing the entire system, end-to-end testing can ensure that the system is reliable, efficient, and user-friendly.



Here are some of the benefits of end-to-end testing:



<ul><li>It can help identify defects not found in unit or integration testing.</li><li>It helps ensure that the system meets the user&#8217;s requirements.</li><li>It can help to improve the reliability and performance of the system.</li><li>It can help to reduce the risk of system failures.</li></ul>



End-to-end testing can be time-consuming and expensive, but it is often essential for ensuring the quality of complex software systems.



Example:



We can have a look at a real-time example to understand this End-to-end testing better:



Scenario: A customer purchases a product from an e-commerce website.



Steps for the end-to-end test:



<ol><li>The customer navigates to the e-commerce website.</li><li>The customer searches for the product they want to purchase.</li><li>The customer adds the product to their cart.</li><li>The customer proceeds to checkout.</li><li>The customer enters their shipping and billing information.</li><li>The customer selects a shipping method.</li><li>The customer reviews their order and clicks &#8220;Place order.&#8221;</li><li>The customer receives an order confirmation email.</li><li>The customer receives their order in the mail.</li></ol>



The end-to-end test would involve testing all the steps above to ensure that the entire process works as expected.&nbsp;



<h3 id="h-what-is-integration-testing"><a href="https://testsigma.com/guides/integration-testing/" target="_blank" rel="noreferrer noopener">What is Integration Testing?</a></h3>



Integration testing is the process of testing how different software modules or components interact. It is a critical part of the software development process because it helps to identify and fix integration issues early on before they cause problems in the final product.



This testing is typically performed after unit testing, the process of testing individual modules or components in isolation. It ensures that the modules or components work together as expected. This is done by combining the modules or components and testing them as a group.



Different approaches to this testing exist, such as top-down integration testing, <a href="https://testsigma.com/blog/bottom-up-integration-testing/" target="_blank" rel="noreferrer noopener">bottom-up integration testing</a>, and sandwich integration testing. The best approach to use depends on the specific software project.



This testing is an essential part of ensuring the quality of software. By identifying and fixing integration issues early on, it can help to prevent costly errors and delays down the line.



Here are some benefits of this testing: 



<ul><li>&nbsp;It helps identify integration issues early on.</li><li>It helps to improve the reliability and robustness of the software.</li><li>It helps to reduce the risk of costly errors and delays.</li><li>It helps to ensure that the software meets the user&#8217;s requirements.</li></ul>



Example:



We can have a look at a real-time example to understand this testing better:



Scenario: A customer is trying to book a flight and hotel using a travel website.



Steps for the <a href="https://testsigma.com/guides/integration-testing/" target="_blank" rel="noreferrer noopener">integration test</a>:



<ol><li>The customer navigates to the travel website.</li><li>The customer enters their travel dates and destination.</li><li>The customer searches for hotels.</li><li>The customer selects the hotel.</li><li>The customer clicks on “Book Now”.</li><li>The customer moves to payment page.</li></ol>



The integration test would test that integration between hotel search, select and payment works.

<h2 id="h-integration-testing-vs-end-to-end-testing-which-test-do-you-need">Integration Testing vs End to End Testing &#8211; Which Test Do you Need?</h2>



If anyone asks you this &#8216;which&#8217; question, you should know the type of testing you need depends on the specific requirements of your software project. In general, you must perform both integration and end-to-end testing.&nbsp;



However, the emphasis on each <a href="https://testsigma.com/blog/the-different-software-testing-types-explained/" target="_blank" rel="noreferrer noopener">type of testing</a> will vary depending on the project. When deciding which type of testing to use, here are some factors to consider:



<ul><li>Complexity of the software system: If the software system is complex, you may need to perform both integration testing and end-to-end testing. This is because complex software systems often have many different modules or components that need to interact with each other. By performing integration testing, you can identify and fix any problems with the interaction between these modules or components.</li></ul>



<ul><li>Risk of defects: If the software system is high-risk, you should perform more extensive, end-to-end testing. This is because high-risk software systems are more likely to have defects that could cause user problems. By performing end-to-end testing, you can identify and fix any defects that could affect the entire system.</li></ul>



<ul><li>Budget and time constraints: Integration testing is less expensive and time-consuming than end-to-end testing. This is because integration testing tests a smaller subset of the software system. If you are on a tight budget or time constraint, consider prioritizing integration testing over end-to-end testing.</li></ul>



<ul><li>Availability of test data: You may need to create <a href="https://testsigma.com/blog/test-data/" target="_blank" rel="noreferrer noopener">test data</a> for end-to-end testing, which can be time-consuming and expensive. You must have access to the necessary test data if you need help performing end-to-end testing.</li></ul>



Here are some examples of when you might use integration testing:



<ul><li>When testing a new module being added to an existing system.</li><li>When testing the interaction between two or more modules in a system.</li><li>When testing a system that is being modified or upgraded.</li></ul>



Here are some examples of when you might use end-to-end testing:



<ul><li>When testing a new system from start to finish.</li><li>When testing a system that real users are using.</li><li>When testing a system that is critical to the business.</li></ul>



Ultimately, the decision of which type of testing to use is up to the software development team. The team should consider the specific requirements of the project and the factors listed above to make the best decision.

<h2 id="h-what-is-test-analysis">What is Test Analysis?</h2>



Test analysis inspects and analyzes the <a href="https://testsigma.com/blog/test-artifacts/" target="_blank" rel="noreferrer noopener">test artifacts </a>to create test conditions or cases. Test analysis aims to collect requirements and create test objectives to establish test conditions. As a result, it&#8217;s also known as Test Basis.



Test analysis is the first step in the test design process. It is essential to perform test analysis carefully and thoroughly to ensure the test cases are complete and adequate.



<h2 id="h-what-is-the-purpose-of-the-test-analysis">What is the purpose of the test analysis?</h2>



Test analysis aims to identify any defects or weaknesses in the software and recommend further testing or improvement. It is an essential part of the software testing process and helps ensure the software is tested.



Here are some specific purposes:



<ul><li>To identify defects in the software.</li><li>To determine the severity of defects.</li><li>To focus on defects for fixing.</li><li>To make recommendations for further testing.</li><li>To improve the testing process.</li><li>To guarantee that the software meets its needs.</li><li>To reduce the risk of defects being released to production.</li></ul>



The test analysis results can improve the<a href="https://www.simplilearn.com/tutorials/devops-tutorial/fundamentals-of-software-testing" target="_blank" rel="noreferrer noopener"> testing process</a>, such as identifying areas where the testing was ineffective or if new test cases need to be created.



<h2 id="why-is-test-analysis-critical">Why is test analysis critical?</h2>



Test analysis is essential because it helps ensure that the correct tests are executed, and the results are accurately interpreted. By carefully analyzing the test results, testers can identify potential defects in the software and recommend corrective actions.



Test analysis is also essential for improving the overall quality of the testing process. By understanding the strengths and weaknesses of the test cases, testers can make necessary adjustments. This will improve the efficiency and effectiveness of the testing process.



<h2 id="what-are-the-criteria-for-test-analysis">What are the criteria for test analysis?</h2>



The criteria for test analysis vary depending on the specific project and the testing methodology used. However, some standard criteria include:



<ul><li>Completeness</li></ul>



Do the test cases and test suites cover all required functionality and performance requirements?



<ul><li>Correctness</li></ul>



Are the test cases well-designed and accurate?



<ul><li>Effectiveness</li></ul>



Are the test cases effective in identifying defects?



<ul><li>Efficiency</li></ul>



Can the test cases be executed quickly and efficiently?



<ul><li>Maintainability</li></ul>



Can the test cases be easily updated and maintained?



<h2 id="issues-encountered-when-test-analysis-is-done-during-black-box-testing">Issues encountered when Test Analysis is done during Black Box Testing</h2>



Black box testing is a type of software testing performed without any knowledge of the internal structure of the software.&nbsp;



This can make test analysis challenging. Because testers need to rely on their understanding of the software requirements and their own experience to design and execute effective test cases.



Some of the specific issues of test analysis in black box testing include:



<ul><li>Identifying all possible inputs: It can be difficult to identify all possible inputs to a black box system, especially for complex systems. This can lead to incomplete test coverage.</li><li>Designing test cases for internal states: It can be challenging to design them for internal states of a black box system, as testers cannot directly observe them. This can lead to ineffective test cases.</li><li>Interpreting test results: It can be challenging to interpret the results of black box tests. This is because the testers cannot directly observe the internal behavior of the system. This can make it difficult to identify the root cause of test failures.</li></ul>



<h2 id="an-approach-to-test-analysis-based-on-test-categories">An Approach to Test Analysis Based on Test Categories</h2>



Test analysis based on test categories is a systematic approach that divides test cases into categories based on their purpose.&nbsp;



This can help ensure that all aspects of the software are tested, and the test cases are effective.



The following are some standard test categories:



Functional testing

Testing can be a serious business, but that doesn&#8217;t mean we can&#8217;t have a little fun with it. So, let&#8217;s look at the steps involved in this.



<h3 id="h-review-test-basis">Review test basis:</h3>



<p id="h-this-is-the-first-step-in-test-analysis-and-it-involves-reviewing-the-documentation-that-forms-the-basis-for-the-test-cases-this-documentation-can-include-the-requirements-design-specifications-risk-analysis-and-any-other-relevant-information">This is the first step in test analysis, and it involves reviewing the documentation that forms the basis for the test cases. This documentation can include the requirements, design specifications, risk analysis, and any other relevant information.&nbsp;



<h3 id="h-identify-test-conditions">Identify test conditions:</h3>



Once the test basis has been reviewed, the next step is identifying the test conditions. A test condition is a specific set of circumstances that must be tested. For example, a test condition for a login feature might be &#8220;a user is able to login when they enter a valid username and password.&#8221;&nbsp;



<h3 id="h-designing-test-cases">Designing test cases:</h3>



The next step is to design the test cases. A test case is a document that describes a specific test condition and the steps that need to be taken to execute the test. The test cases should be designed to cover all of the identified test conditions, and they should be written clearly and concisely.



<h3 id="h-expected-and-unexpected-inputs">Expected and unexpected inputs:</h3>



The final step is to identify the expected and unexpected inputs for each test case. The expected input is the input that is expected to produce the desired output. The unexpected input is an input that is not expected to produce the desired output. The goal of this step is to ensure that the test cases are comprehensive and that they cover all of the possible scenarios.
