Python Testing with pytest

Chapter 16Advanced Parametrization

We’re going to wrap up this book by swinging back to parametrization and look at some advanced techniques. In Chapter 5, ​Parametrization​, we looked at parametrizing tests and fixtures, and you learned how to implement parametrized testing with the hook function, pytest_generate_tests(). However, we left the chapter with some pretty simple parametrizations of a test using one parameter with string values. We’re going to do so much more in this chapter.

In this chapter we’ll look at:

• Using data structures or objects as values. That complicates the test case identifier slightly, but we’ll use custom identifiers to make the test node IDs readable.

• Using dynamic values. We’ll use a function to dynamically generate ...
