<h3 class="wp-block-heading" id="h-what-is-static-testing">What is static testing?</h3>



<a href="https://testsigma.com/blog/static-testing/" target="_blank" rel="noreferrer noopener">Static testing</a> does not involve running the code; it is a static analysis of the source code to find potential issues early in the development process through code reviews, inspections, and the use of static analysis tools.&nbsp;



<h3 class="wp-block-heading" id="h-what-is-dynamic-testing">What is dynamic testing?</h3>



<a href="https://testsigma.com/blog/dynamic-testing/" target="_blank" rel="noreferrer noopener">Dynamic testing</a> is a reactive technique since it involves executing the code to find real bugs and issues. This includes unit, integration, system, and acceptance testing as well as verifying functionality and performance to verify that defects are realized.



<h2 class="wp-block-heading" id="h-static-testing-vs-dynamic-testing-key-differences">Static Testing Vs Dynamic Testing &#8211; Key Differences</h2>



Let us look into the major differences between both testing methods:



<figure class="wp-block-table"><table><tbody><tr><td>Features</td><td>Static Testing&nbsp;</td><td>Dynamic Testing&nbsp;</td></tr><tr><td>Definition</td><td>A testing technique that reviews and analyzes software documentation, source code, and other artifacts before execution.</td><td>A testing technique that evaluates software behavior when it is executed.</td></tr><tr><td>Objective</td><td>To identify defects and improve software quality early in development.</td><td>To validate the software’s functionality and behavior in different scenarios.</td></tr><tr><td>Types of Testing</td><td><a href="https://testsigma.com/blog/role-of-a-software-tester-in-code-reviews/" target="_blank" rel="noreferrer noopener">Code review</a>, walk-through, and inspection</td><td>Unit, integration, system, acceptance, performance, security, and user acceptance testing.</td></tr><tr><td>Timing</td><td>It begins early in the software development process and continues forever.</td><td>Conducted after coding and development are complete.</td></tr><tr><td>Results</td><td>Includes reviews, walkthroughs, and inspections of the software.&nbsp;</td><td>Includes functional, integration, system, performance, and usability tests&nbsp;</td></tr><tr><td>Automation</td><td>These tests, generally, cannot be automated.</td><td>These can be automated.</td></tr></tbody></table></figure>



<h2 class="wp-block-heading" id="h-static-testing-and-dynamic-testing-how-to-choose-between-them">Static Testing and Dynamic Testing &#8211; How to Choose Between them?</h2>



When choosing between these testing, it is essential to consider the specific requirements and objectives of the <a href="https://testsigma.com/guides/test-process/" target="_blank" rel="noreferrer noopener">testing process</a>. Both approaches have advantages and limitations, so a justification for selecting one over the other depends on various factors.



Static testing involves analyzing code without executing it, while dynamic testing involves running code to identify any issues. The choice between static and dynamic testing largely depends on the desired outcome. Static testing may be the way to go if you’re looking to catch coding errors early and improve code quality.&nbsp;



On the other hand, dynamic testing is likely the better choice if you’re concerned with how a program behaves when running.&nbsp; You could also choose to do both according to the results you are expecting.



I conclude by saying both approaches have their strengths and weaknesses. So, it should be completely a decision based on the project’s specific needs.



<h2 class="wp-block-heading" id="h-summary">Summary</h2>



In summary,&nbsp; both testing techniques play a vital role in software development and complement each other by thoroughly reviewing the software’s quality.



<h2 class="wp-block-heading" id="h-frequently-asked-questions">Frequently Asked Questions</h2>



<h3 class="wp-block-heading" id="h-what-are-static-and-dynamic-testing-in-agile">What are static and dynamic testing in agile?</h3>



When, just like the software development activities in Agile, the static and dynamic testing is also done in iterations according to the tasks taken up for each iteration, it is termed “static and dynamic testing in Agile”.



<h3 class="wp-block-heading" id="h-is-black-box-testing-static-or-dynamic">Is black-box testing static or dynamic?</h3>



Black-box testing is dynamic testing. The main objective of <a href="https://testsigma.com/guides/black-box-testing/" target="_blank" rel="noreferrer noopener">black-box testing</a> is to assess the software’s functionality, usability, performance, security, and other non-functional aspects.



<h3 class="wp-block-heading" id="h-what-are-static-and-dynamic-testing-tools">What are static and dynamic testing tools?</h3>



Some examples of static testing tools include SonarQube, Crucible, Code Collaborator, and FindBugs. Some examples of dynamic testing tools include Testsigma, Selenium, SoapUI, JMeter, and LoadRunner.

We&#8217;re excited to announce our latest release, packed with new features to take your testing to the next level. We built these features with testing efficiency in mind for quality engineering teams delivering quality releases at speed.



Let&#8217;s begin!



<ol class="wp-block-list"><li>Powerful new API testing capabilities .Our brand new API testing interface comes with powerful features that support real-time API response validation, testing of different API methods (GET, PUT, POST, DELETE, PATCH), and data-driven API testing. <a href="https://testsigma.com/automated-api-testing" target="_blank" rel="noreferrer noopener">Learn more</a>.&nbsp;</li></ol>



<ol class="wp-block-list" start="2"><li>Concatenate dynamic test data You can now dynamically generate and use multiple different sets of data and concatenate them with Testsigma&#8217;s test data concatenation feature. It lets you easily concatenate any base strings with dynamic user properties and run the same test for as many iterations as you need. Building dynamic tests saves you time and reduces the risk of errors. <a href="https://testsigma.com/docs/test-data/types/concat/" target="_blank" rel="noreferrer noopener">See documentation</a>.&nbsp;</li></ol>



<ol class="wp-block-list" start="3"><li>Download and white-label PDF reports Generate detailed reports for management reporting or your own audit and analysis for each build. With this feature, you can export reports to PDF, complete with test cases, test steps, and screenshots. Plus, you can include your firm&#8217;s <a href="https://www.goldenflitch.com/blog/how-much-does-logo-design-cost" target="_blank" rel="noreferrer noopener">brand logo</a> to ensure the report follows any copyright and company guidelines. Note: This feature is only available to Enterprise users (<a href="https://testsigma.com/docs/reports/export-reports/export-report-pdf/" target="_blank" rel="noreferrer noopener">See documentation</a>).</li></ol>



<ol class="wp-block-list" start="4"><li>Nested Step Groups Group the test steps that are generally carried out together, and reuse the group everywhere. For instance, in a data-driven test case, you can iterate over user profiles one by one and perform different actions based on the profile type. By creating nested step groups, you can save time and reduce the risk of errors. <a href="https://website.testsigma.com/docs/test-cases/step-types/nested-groups/" target="_blank" rel="noreferrer noopener">Learn more</a></li></ol>



<ol class="wp-block-list" start="5"><li>Disable Test Cases in a Test Plan Sometimes, you know that certain test cases are bound to fail due to known existing bugs. To avoid wasting time on these failures, you can now disable test cases that you don&#8217;t want to run at the moment. This feature allows you to decouple your results from known failures and gives you more control over your testing. <a href="https://testsigma.com/docs/test-plans/disable-test-cases-in-test-plans/" target="_blank" rel="noreferrer noopener">Know more</a></li></ol>



<ol class="wp-block-list" start="6"><li>Enhance test data mid-execution with new NLP Our new NLP feature lets you write values to test data profile columns during test case execution. For example, if you&#8217;re iterating over a series of SKUs, you can log the price of each SKU from the UI and write it to the desired column for a test data profile. Later, you can use this test data profile in another test case to verify if the prices in another pin code or city are the same. This feature makes it easy to add data from the app being tested to your test data profile or log status for certain actions. <a href="https://testsigma.com/docs/test-data/add-values-to-test-data-profile/" target="_blank" rel="noreferrer noopener">Know more</a></li></ol>

<h2 class="wp-block-heading" id="h-difference-between-functional-and-integration-testing-overview">Difference Between Functional and Integration Testing &#8211; Overview</h2>



Functional testing helps verify that the software works as expected and meets user’s expectations. It is a type of black-box testing that involves testing various aspects of the application, such as user interfaces, APIs, databases, and other system components, to validate that they are working as expected. It doesn&#8217;t involve looking into the internal working of software functions &#8211; just observing output on the appropriate input.

Integration testing is when two or more components are integrated and tested as a whole. It ensures that smaller components are working correctly together after integration and provides an error-free user interface for the end users. It helps to improve the performance and scalability of the software and increase the overall software quality.

<h2 class="wp-block-heading" id="functional-testing-vs-integration-testing-purpose">Functional Testing vs Integration Testing &#8211; Detailed Comparison </h2>



<h3 class="wp-block-heading" id="functional-testing-vs-integration-testing-purpose">Purpose</h3>



Purpose of Functional Testing



Functional testing helps verify that the software meets the functional requirements. It ensures that the software behaves as expected and aligns with the business requirements.&nbsp;



It checks everything like the end-to-end workflows, functionality of the application, APIs, database, client-server communication, security, etc. Every functionality is tested with different inputs, and the test result will be compared with the expected output.



Purpose of Integration Testing



Integration testing helps test the interactions between different software modules after they have been individually tested.&nbsp;



The main aim of integration testing is to ensure that the integrated components work together as intended and to identify any issues that might arise due to their interactions. Typically, integration is done after unit testing.&nbsp;



<h3 class="wp-block-heading" id="workflow-comparison">Workflow Comparison</h3>



Let&#8217;s take a look at the workflow difference between the integration test vs functional test,



Functional Testing Workflow



<ul class="wp-block-list"><li>Understand the software requirements and functional specifications provided by the development team or stakeholders.</li><li>Create test cases that cover different functional aspects of the application and test scenarios.</li><li>Now, create a document for the traceability matrix after designing the test cases.</li><li>Create test data and start executing test cases.</li><li>Once the test is complete, compare the actual result with the expected result to validate if the product works as it is intended to be.</li></ul>



Integration Testing Workflow



<ul class="wp-block-list"><li>Understand the requirements and specifications provided by the developers.</li><li>First, divide the application into smaller modules and understand each module&#8217;s functionality.&nbsp;</li><li>Next, find where you start and finish in each part and create a test plan.&nbsp;</li><li>Choose the best integration testing approach based on the app&#8217;s needs and identify test conditions.</li><li>Then, start to design test cases to perform integration testing and analyze the results.</li></ul>



<h3 class="wp-block-heading" id="use-case-comparison">Use Case Comparison</h3>



Functional testing and integration testing are both critical aspects of the software testing process, but they serve different purposes and focus on different aspects of a software application. Let&#8217;s consider different use cases to understand this,



Functional Testing Use Case



Use Case: Consider you are <a href="https://testsigma.com/blog/ecommerce-testing/" target="_blank" rel="noreferrer noopener">testing an e-commerce application</a>&#8216;s shopping cart functionality.



<ul class="wp-block-list"><li>User Scenario: Add to Cart Functionality</li><li>Test Description: Test the cart&#8217;s functionality. That is, when a user adds a product to the cart, the cart should be updated with the correct name, price, and quantity of the product.</li><li>Expected Result: The application should accurately update the cart and show the correct product details.</li></ul>



Integration Testing Use Case



Use Case: Consider an e-commerce website where users can browse products, add them to their cart, and proceed to checkout. The website is made up of several components: a product catalog, a shopping cart, a user authentication system, and a payment gateway.



<ul class="wp-block-list"><li>User Scenario: Test the interactions between these components to ensure they work as expected.</li><li>Integration Test: Test the cart module, checkout module, etc. That is, adding multiple products to the cart and verifying the cart&#8217;s accuracy. Next, add a product to the cart, log out, and then log in again to ensure the cart items are retained. Then, add products to the cart, proceed to checkout, and verify that the payment gateway works correctly.</li><li>Expected Outcome: The user should be able to browse products, add items to the cart, login, proceed to checkout, and complete the payment.</li></ul>



<h3 class="wp-block-heading" id="challenges">Challenges </h3>



Let&#8217;s take a look at the challenges between integration testing vs functional testing,



Challenges of Functional Testing



<ul class="wp-block-list"><li>Designing comprehensive and effective test cases for all possible functional scenarios can be complex and time-consuming.&nbsp;</li><li>Functional testing can become complex when requirements change frequently, requiring constant updates to test cases and test data.</li><li>Functional changes or bug fixes in one area of the software can unintentionally impact other areas. Ensuring that new functional additions don&#8217;t break existing functionality requires robust regression testing. Get here the Comparison between <a href="https://testsigma.com/guides/integration-testing/" target="_blank" rel="noreferrer noopener">Regression Testing vs Integration Testing</a></li><li>Defining clear test requirements for every change is difficult due to the detailed and measurable information they contain.</li><li>Keeping a simple report to decide whether something works or not with functional tests might not work well. This is because reports are divided based on features and defects.</li><li>It takes a long time to fix recurring issues and to set up the test environment.</li><li>Creating test metrics to analyze and improve applications is challenging due to software complexities and varying test requirements.</li></ul>



Challenges of Integration Testing



<ul class="wp-block-list"><li>When you replace mock data with real modules, you might find new bugs.</li><li>It is time-consuming and needs good coding skills to create integration tests because programs and data required for testing are mocked.&nbsp;</li><li>It is difficult to understand the logic because the software code is written by multiple teams separately.</li><li>It is difficult to understand the code because it is written by different teams separately.</li><li>Testing integrated parts of the software is complicated because various things like the database, platform, and software environment affect the tests.</li><li>Choosing the right testing approach can become harder when you have multiple options to consider.</li><li>Integration testing gets even more complex when external features, tools, and libraries from different companies with their own dependencies are involved.</li></ul>

<h2 class="wp-block-heading" id="h-wrapping-up">Wrapping Up</h2>



Functional testing and integration testing are closely related to each other, but they are not the same. We hope that this article helped you understand them and their differences better.



<h2 class="wp-block-heading" id="h-frequently-asked-questions">Frequently Asked Questions</h2>



<h3 class="wp-block-heading" id="h-is-functional-testing-manual-or-automation">Is functional testing manual or automation? </h3>



Functional testing can be both manual and automated. Manual functional testing involves human testers executing test cases manually to verify the software&#8217;s functionality. On the other hand, <a data-wpil="url" href="https://testsigma.com/ai-agents-automated-functional-testing/" target="_blank" rel="noreferrer noopener">automated functional testing</a> involves using automation testing tools to execute test cases and compare actual results with expected results. Automated functional testing is typically faster, more efficient, and repeatable than manual testing.



<h3 class="wp-block-heading" id="h-is-integration-testing-the-same-as-uat">Is integration testing the same as UAT? </h3>



No, integration testing is not the same as user acceptance testing (UAT). They both serve different purposes in the <a href="https://aws.amazon.com/what-is/sdlc/#:~:text=The%20software%20development%20lifecycle%20(SDLC,expectations%20during%20production%20and%20beyond." target="_blank" rel="noreferrer noopener">SDLC</a>. Integration testing is focused on verifying the interactions between different modules of the application, while UAT is focused on validating the software from the perspective of end-users.
