We all know that software release cycles are becoming shorter and more frequent, which is why unit testing is a necessary practice. Yet, many organizations don’t allocate proper resources to conduct unit testing or overlook it entirely. Here’s how unit testing makes your system stronger and more reliable:
- Testing validates your code and functionality, providing a solid foundation for future development and extending test scenarios.
- Defects can be identified at early stages of the production process, which limits the costs of fixing them in later stages of the development cycle
- Unit tested code is safer to refactor and more predictable.
- Developers are forced to consider how well the production code is designed in order to make it suitable for unit testing.
- Writing unit tests makes developers look at their code from a different perspective and helps them understand the production code better.
- Unit tests are an additional medium for collecting feedback about the production code and how it should behave.
