It typically begins after the individual software modules have been unit tested and after any required interfaces between modules have been created.<\/p>\n<p>The types of integration testing include:<\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Top-Down_Integration_Testing\"><\/span><strong>1. Top-Down Integration Testing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Top-down integration testing is a software testing method where individual modules are integrated from the top of the module hierarchy. A stub, a dummy representation of the module, replaces each lower-level module. Meanwhile, a driver simulates the calls to the stubs. Testers then feed data into the driver and verify the output for accuracy.<\/p>\n<p>The main objective of top-town integration testing is to verify the functional correctness of the integrated modules. It is typically used in conjunction with bottom-up integration testing to get complete test coverage.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Bottom-Up_Integration_Testing\"><\/span><strong>2. Bottom-Up Integration Testing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Bottom-up integration testing is a software testing approach in which individual modules are tested before being integrated with others. Its purpose is to gradually build up the system from smaller units to larger ones rather than starting with the entire system immediately.<\/p>\n<p>In the process, it allows for more focused testing on individual components and can help to identify issues early on in the development process. Once all of the individual modules have been properly tested, they can be combined and tested as a group.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Incremental_Integration_Testing\"><\/span><strong>3. Incremental Integration Testing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This type combines elements of top-down and bottom-up integration testing, starting with some high-level modules and then adding lower-level modules. It provides more controlled and focused testing of specific areas of the system.<\/p>\n<p>Software integration testing offers many benefits:<\/p>\n<ul>\n<li>It helps to verify that the interfaces between modules are working correctly.<\/li>\n<li>It can uncover errors and issues that you cannot find through unit testing alone.<\/li>\n<li>The process allows for more comprehensive testing of the system as a whole.<\/li>\n<li>It can improve the overall quality of the software product.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Perform_Software_Integration_Testing\"><\/span><strong>How to Perform Software Integration Testing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The best approach to integration testing depends on the specific system you are testing and the development process used.Software integration testing services can also help you choose the most ideal method.<\/p>\n<p>However, it usually involves the following:<\/p>\n<ul>\n<li><strong>Define the scope of integration testing. <\/strong>Determine what exactly you want to test. It will help to focus the testing efforts and ensure that you can cover all important aspects of the system.<\/li>\n<li><strong>Review requirements document. <\/strong>To properly test the system, you need to have a clear understanding of what it is supposed to do. The requirements document should provide this information. It includes information such as what inputs you should feed into the system and the expected outputs.<\/li>\n<li><strong>Identify all of the interfaces between modules.<\/strong> External interfaces are those that connect to other systems like databases. Internal interfaces are those between different modules within the system.<\/li>\n<li><strong>Determine the integration testing approach.<\/strong> The best approach will depend on the specific system under test. For instance, you may want to use a top-down if the system has a layered architecture.<\/li>\n<li><strong>Design a test plan. <\/strong>A test plan outlines the testing approach and provides a roadmap for carrying out the tests. It should include information such as what types of tests to run, how to prepare the test environment, and who will be responsible for each task.<\/li>\n<li><strong>Prepare the test environment. <\/strong>The test environment should be set up so that it mimics the real-world environment as much as possible. This includes things like configuring the system under test and any other necessary software and hardware.<\/li>\n<li><strong>Create test cases. <\/strong>Once you have determined the scope and interfaces, you can start creating test cases. You identify the factors a tester can use to evaluate whether an application or software system is working as expected.<\/li>\n<li><strong>Validate results. <\/strong>After running the tests, you need to validate the results to ensure that they are accurate. This includes manually checking the outputs to see if they match the expected results. Document findings. All test results should be properly documented. This includes information such as what worked and what didn\u2019t, as well as any errors or defects found.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Final_Words\"><\/span><strong>Final Words<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Integration testing is an important part of the <a href=\"https:\/\/www.hitechwork.com\/basic-software-development-models-and-methodologies\/\">software development process<\/a>.
