pytest are Python functions with “test_” prepended or “_test” appended to the function's name - although you can use a class to group multiple tests. Overall, the learning curve for pytest is much shallower than the likes of unittest since you’re not required to learn any new ...
Create a class extending the classunittest.TestCase. Write the test methods starting with the test keyword liketest_functionName(self)and use assert methods to verify the behavior of the code being tested. Run the commandpython -m unittest test_example.pyin the terminal or invoke the main metho...
where it hits our entry point and is then told to use theunittesttest runner. A similar way to run this test file from the command line is to use the python-m unittest test_my_sumcommand as pictured below.
Two of the most popular frameworks in Python to write and run unit tests are the unittest package from the Python standard library and the pytest package. For this series of articles I'm going to use a hybrid testing solution that incorporates parts of both packages, as follows:...
