Module Testing vs Integration Testing
Below are the differences between module testing and integration testing:
Parameters | Module Testing | Integration Testing |
---|---|---|
Objective | Tests the functionality of a single module. | Tests the interaction between components. |
Error location | Identifies errors in the functionality of the module. | Identifies errors in the interfaces and dependencies between components. |
Testing order | Is typically performed before integration testing. | Is typically performed after unit testing. |
Access to source code | Does not require access to the source code. | May require access to the source code. |
Requirement of test harness or driver | Does not require special test harnesses or drivers. | May require special test harnesses or drivers. |
Testing level | Is typically performed at the component level. | Can be performed at the component, subsystem, or system level. |
Automatic/ Manual | Is often performed automatically. | Is often performed manually. |
Time taken | Usually takes less time to execute than integration tests. | Usually takes longer to execute than unit tests. |
Cost | Is less expensive to execute than integration tests. | Is more expensive to execute than unit tests. |
Module Testing
Module testing is a type of software testing where individual units or components of the software are tested. The purpose of module testing is to isolate a section of code and verify its correctness. Module testing is usually performed by the development team during the early stages of software development. However, it can also be done by independent testers as part of regression testing. There are various methods of module testing, but the most common one is black-box testing. In black-box testing, the test cases are designed based on the functionality of the code, without taking into consideration its internal structure. Other methods include white-box testing (which looks at the internal structure), grey-box testing (which combines both black-box and white-box testing), and glass-box testing (which tests all possible inputs and outputs). No matter which method you choose, module testing is an important part of ensuring the quality of your software. In this blog post, we will take a closer look at module testing and how it can benefit your software development process.
