Unit test

Unit tests are typically written using a testing framework, such as JUnit for Java or PyTest for Python, that provides the necessary tools and infrastructure for creating, executing, and managing tests. Each unit test focuses on a specific piece of code, such as a function or method, and verifies that it behaves as expected when given certain inputs. The test cases should include positive (expected behavior) as well as negative (unexpected behavior) scenarios.

Unit tests are usually executed as part of a continuous integration pipeline, where every time a change is made to the code, the unit tests are automatically run. If a test fails, the developer is notified and can immediately address the issue. This helps to catch bugs early and ensures that the code remains stable and consistent as it evolves.

It is important to note that unit testing is just one aspect of software testing, and should be complemented by other types of testing, such as integration testing, system testing, and acceptance testing, to ensure the overall quality and reliability of the software application. Additionally, effective unit testing requires a well-designed code architecture, with clear boundaries between units and well-defined interfaces, to ensure that the units can be easily isolated and tested in isolation.
