Study Notes
Integration Testing Methods in Software Development
- Integration testing is the process of testing different components of a software application together as a single unit.
- Integration testing aims to discover any defects that may arise when the modules are integrated and must interact with each other.
- Integration testing is also known as string testing or thread testing.
- System integration testing (SIT) is the process of building a "working" version of the system by putting modules together in an incremental manner.
- Integration testing is considered complete when important behaviors are fully described and all test cases have been executed and defects have been fixed.
- Advantages of integration testing include fast testing process, high code coverage, and efficient detection of system-level issues.
- Integration testing can be performed at different levels of granularity, such as intra-system testing, inter-system testing, and pairwise testing.
- Common approaches to integration testing include incremental testing, top-down integration testing, bottom-up integration testing, sandwich integration testing, and big bang integration testing.
- Incremental integration testing involves conducting tests in a series of cycles, gradually integrating more modules into the system.
- Top-down integration testing starts with integrating the top-level modules and gradually integrating lower-level modules, observing system-level functions along the way.
- Bottom-up integration testing starts with integrating the lowest-level modules and gradually integrating higher-level modules, allowing for meaningful integration of other modules.
- Big bang integration testing involves testing the entire system as a whole after all modules have been individually tested, but it can be time-consuming and difficult to track errors.
