unittest — Unit testing framework — Python 3.10.7 documentation

To achieve this,  unittest supports some important concepts in an object-oriented way:

• test fixture

• A test fixture represents the preparation needed to perform one or more tests, and any associated cleanup actions. This may involve, for example, creating temporary or proxy databases, directories, or starting a server process.

• test case

• A test case is the individual unit of testing. It checks for a specific response to a particular set of inputs.  unittest provides a base class,  TestCase, which may be used to create new test cases.

• test suite

• A test suite is a collection of test cases, test suites, or both. It is used to aggregate tests that should be executed together.

• test runner

• A test runner is a component which orchestrates the execution of tests and provides the outcome to the user. The runner may use a graphical interface, a textual interface, or return a special value to indicate the results of executing the tests.
