Python unittest is a built-in framework in Python for writing and running automated tests. It is a testing library that is used to test Python code and is based on the xUnit testing framework. The unittest module provides a set of tools for constructing and running tests, as well as reporting the results.
Using unittest, developers can create test cases, test suites, and test runners to automate testing of Python code. Test cases are individual tests that check a small piece of functionality in a program. Test suites group together multiple test cases that are related to each other. Test runners are responsible for executing the test cases and generating reports that show the results of the tests.
In unittest, test cases are created by subclassing the TestCase class and defining methods that start with the word "test". These methods are then run automatically by the test runner. Developers can use various assertion methods available in unittest to check that the code being tested is working correctly.
Overall, unittest is a powerful tool for automating testing in Python and is widely used by developers to ensure that their code is working as expected.
