Python Testing with pytest

Using Indirect Parametrization

The final parametrization technique we’re going to look at is indirect parametrization. An indirect parameter is one that gets passed to a fixture before it gets sent to the test function. Indirect parametrization allows us to perform work based on the parameter value.

The way it works is to set indirect to a list of parameter names you want to be indirect, like indirect=["param1", "param2"]. You can also set indirect=True if you want all parameters to be indirect. Then you need a fixture with the same name as the parameter.

As an example, let’s say we have expanded Cards to have different access rights for different user roles. We can parametrize a test with a user parameter:

ch16/test_indirect.py

@pytest.mark.parametrize( ...
