Python Unit Testing Competency (Intermediate Level)

Topics covered

• apply markers to tests and run only those tests which contain specific marker, and skip the execution of specific tests unconditionally
• apply module and function level scopes for fixtures functions
• create a readme file for a Python module which bundles documentation and testing in a single file
• create a script which uses the unittest framework by using the PyCharm IDE
• debug test scripts using the python debugger
• define a script testing out multiple functions in the source using the PyCharm IDE
• execute tests defined in multiple scripts using pytest
• group test cases into a test suite and execute them using a test runner
• parametrize calls to a function an application using the pytest parametrize decorator
• pick the tests to execute based on the test function names
• recall how to set doctest to ignore whitespace in the output of tests tests
• recognize when a test script will benefit from the use of fixture functions
• recognize where doctests can be placed within source code
• use fixtures to define common operations for test functions
• use the ELLIPSIS directive to account for unpredictable output in doctests
• use the ELLIPSIS directive to check if the code raises exceptions for incorrect input values
• use the makeSuite function to initialize a test suite
• use the setUp and tearDown functions to define common operations for tests in a script
