What is the Unit test? Why perform Unit Testing?
The process of unit testing is a crucial aspect of automated testing for digital applications. It provides stability and resilience by evaluating the performance of individual modules. Nonetheless, selecting a unit testing methodology may prove to be arduous owing to the diverse methodologies employed by testing teams. Before testing a single unit, it’s important to make sure everyone involved agrees on what works best before starting.
What is Unit Testing?
Individual units or components of the software are subjected to testing in unit testing. The goal is to make sure that every part of the software works correctly. The process of Unit Testing is carried out by the developers during the development (coding) phase of an application. Unit Tests check a part of the code to make sure it’s correct. A unit can be a single thing like a function, method, procedure, module, or object.
Unit testing is the first level of testing done before integration testing in the SDLC, STLC, and V Models. Unit testing is a type of testing called White Box, and it’s usually done by the person who makes things. Though in the practical world, due to time constraints or developers’ reluctance to test, QA engineers also do unit testing.
Why perform Unit Testing?
The importance of unit testing cannot be overstated, as software developers may attempt to save time by performing minimal unit testing. However, this approach is a myth, as inadequate unit testing can result in high-cost defects being rectified during System Testing, Integration Testing, and even Beta Testing subsequent to the application’s development. It saves time and money if proper unit testing is done in early development.
The main reasons for performing unit testing in software development are listed.
- Unit tests facilitate the resolution of bugs at an early stage of the development process, thereby reducing expenses.
- It helps the developers understand the code used for testing and allows them to make changes quickly.
- Good unit tests are a good way to document a project.
- Unit tests help with using the same code over and over again. Make sure you move your code and tests to your new project. Modify the code until the tests are run again.
