211: Stamp out test dependencies with pytest plugins

We want to be able to run tests in a suite, and debug them in isolation, and have the behavior be the same.  
If the behavior is different in isolation vs in a suite, it's a nightmare to debug. 

In this episode, we'll talk about:

• Causes of dependence
• Testing for dependencies using plugins
• Debugging test dependencies

Plugins discussed:

• pytest-randomly
• pytest-reverse
• pytest-random-order

Help support the show AND learn pytest: 

• The Complete pytest course is now a bundle, with each part available separately.
  • pytest Primary Power teaches the super powers of pytest that you need to learn to use pytest effectively.
  • Using pytest with Projects has lots of "when you need it" sections like debugging failed tests, mocking, testing strategy, and CI
  • Then pytest Booster Rockets can help with advanced parametrization and building plugins.
• Whether you need to get started with pytest today, or want to power up your pytest skills, PythonTest has a course for you.
