For this tutorial, we will be using unittest which is the built-in testing framework in Python standard library. It contains both the testing framework and the test runner and offers a variety of features ranging from test automation and aggregating tests into collections to the independence of t...

For example, you’ll usepython3 -m unittest main.pyto run unittest as the main module when running main.py. We mentioned that all other positional arguments that we pass in will be collected in theargsvariable. Here’s an example:
for writing tests. It takes a long time and might bake some bugs into the test suite rather than preventing them. Luckily, there is an extremely versatile tool that makes this easier: The Python debuggerpdb. And if you’re using pytest to run your tests, it has a handy integration with...
We run the test, and theRunwindow pops up in the IDE. Notice that the windows’ title in the output saysTests failed: 1 of 1 test. Further, we get the message withAssertionError, and the expected value to be 1, and the actual value is 2. ...
