Unittest
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.
unittestprovides 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.
