Module Testing vs Unit Testing
Below are the differences between module testing and unit testing:
| Parameters | Module Testing | Unit Testing |
|---|---|---|
| Testing level | Module testing is done at the tester’s level. | Unit testing is done at the developer’s level |
| Testing approach | Module testing is a top-down approach. | Unit testing is a bottom-up approach |
| Before/ After integration testing | Module testing is done after the integration of the modules. | Unit testing is done before the integration of the modules |
| Objective | Module testing is done to test the functionality of the module. | Unit testing is done to test the functionality of the code |
| Who performs? | Module testing, the test cases are written by the testers. | In unit testing, the test cases are written by the developers |
| Testing input | Module testing is done on the module. | Unit testing is done on the code |
| Blackbox/ Whitebox testing | Module testing can be either white box or black box testing. | Unit testing is white-box testing |
| Testing site | Module testing is done at the customer’s site. | Unit testing is done at the developer’s site |
| Scope | The scope of module testing is larger than the scope of unit testing. | The scope of unit testing is smaller than the scope of module testing. |
| Testing machine | Module testing is done on the remote machine. | Unit testing is done on the local machine |
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.
