Expertise Level


Explore several types of testing frameworks for Python applications, including the unittest framework, pytest, and doctest, in this 12-video course. First, you will learn how to define and run tests, and how to streamline tests by using fixtures. You will learn the important features of the pytest framework to create small test units, and to define and run individual tests. Next, you will learn to group tests into multiple scripts, and how to execute multiple test scripts within a single run. Learners will observe how to create a simple test, and learn to increase the complexity by defining test scripts to cover multiple tests for your application. You will explore the execution and skipping of specific tests in scripts, then learn to simplify tests by using parameterization. You will learn how to apply filters on different tests, and to execute tests with a certain string in the test name, and examine the use of markers in a test. Finally, you will learn how to use fixtures to run operations common to multiple tests.
