Unit Testing
A unit is the smallest building block of a software. Such a unit can be: a class, a method, an interface etc. Unit testing is the process of validating such units of code.
Benefits
Some of the benefits are:
- Proof of your code
- Better design - Thinking about the tests can help us to create small design elements, thereby improving the modularity and reusability of units.
- Safety net on bugs - Unit tests will confirm that while refactoring no additional errors were introduced.
- Be able to detect and remove defects in a more cost effective manner compared to the other stages of testing.
- Be able to test parts of a source code in isolation.
- Making debugging more efficient by searching for bugs in the probable code areas.
- Documentation - Designers can look at the unit test for a particular method and learn about its functionality.
