Unit Testing in the Development Process

Understanding how unit testing fits into the development workflow is key to writing reliable software. In a typical workflow, you write individual units of code, such as functions or methods, and test them in isolation before integrating them into the larger project.

This approach ensures that each part works as intended before it interacts with other components. As a result, errors are easier to spot early, fixes are more straightforward, and the overall quality and stability of the project are easier to maintain over time.

Unit tests are especially valuable for teams working together. They provide a shared understanding of how code is expected to behave, making code reviews more effective and reducing the risk of introducing bugs when merging changes. When everyone writes and maintains unit tests, it becomes easier to spot mistakes, discuss improvements, and trust that code changes will not break existing features.
