Python Testing with pytest

Review

There’s a lot of parametrization fun in this chapter! We covered

• using data structures and objects as parameter values and how that results in numbered test IDs;

• creating custom identifiers using ids and ID functions, including repr, str, custom functions, and lambdas;

• using the id setting of pytest.param for identifiers;

• using a list for IDs and using dictionaries to keep track of test cases and identifiers;

• using functions for parameter values, which allow us to dynamically create values at test collection time;

• using multiple parameters and even stacking parametrize decorators to create a test matrix, and

• moving parameter values from fixture to test function using indirect parametrization.
