Why unit testing ?

Unit testing is a software testing technique in which individual units or components of a software application are tested in isolation from the rest of the system. There are several reasons why unit testing is important:

  1. It helps to catch bugs early in the development process, which makes it easier and less costly to fix them.

  2. Unit tests provide a way to ensure that the code works as intended and that new changes don’t break existing functionality.

  3. It helps to improve the design of the code by making it more modular and testable.

  4. Unit tests serve as living documentation for the code, making it easier for other developers to understand and maintain it.

  5. It enables developers to make changes to the code with confidence, knowing that if a unit test fails, it means that something is wrong and needs to be fixed.

  6. It is a practice that helps with Continuous Integration and Continuous Deployment, allowing developers to catch issues early on in the development cycle and release new features faster.

In this blog series, we will explore these reasons in more detail and discuss the benefits of unit testing, the different types of unit tests, and best practices for writing effective unit tests.
