What is Integration Testing?

2024-09-11

Integration testing is a method of software testing that tests whether the interaction and collaboration between different software modules are normal. The main purpose of integration testing is to ensure that different software modules can work seamlessly together to form a complete software system and meet the system requirements and specifications.

In integration testing, testers combine software modules that have passed unit testing and test their interactions and collaboration. These software modules can be written by the same development team or different development teams, or even provided by different companies or organizations.

Integration testing usually consists of the following steps:

Define the integration test plan: Determine the plan for the scope, test objectives, test methods, and test time of the integration test.

Set up an integrated test environment: Prepare an integrated test environment, including hardware, software, network, and other aspects.

Integration test case design: Write integration test cases according to requirements and specifications to test the interaction and collaboration between software modules.

Integration test execution: Execute integration test cases to verify whether the interaction and collaboration between different software modules are normal, and discover and fix defects.

Integration test report: summarizes the integration test results, including test coverage, test results, and defect reports.

Integration testing is an important part of the software testing process. It can help the development team discover and solve interaction problems between software modules early in the development cycle and ensure the quality and reliability of the entire software system.
