Unit & Integration Testing
Writing automated tests to verify that individual components and combined parts of an application work as expected.
Where we use it
We write unit and integration tests to ensure that our code is reliable and works as expected. Unit tests verify individual components in isolation, while integration tests ensure that different parts of the application work together correctly. This practice helps us catch bugs early and refactor code with confidence.
Strengths
- Ensures code reliability and correctness.
- Facilitates safe refactoring and future changes.
- Provides living documentation of the code's behavior.
Trade-offs
- Writing and maintaining tests takes time.
- Can be difficult to write good tests for complex UI interactions.
- Achieving high test coverage can be challenging.
