In pytest parameters to test functions are usually fixtures. You have taken responsibility. In other words, this fixture will be called one per test module. The type annotations have been checked with mypy, which is the only type checker supported at the moment; other type-checkers might work but are not currently tested.

If you are unfamiliar with how pytest decorators work then please read the fixture documentation first as it means that you should no longer use the @requests_mock.Mocker syntax that is present in the documentation examples. Instead of implementing and defining a function, which would be used repeatedly, just call the same function as a fixture object and get it executed. Bug#846045; Package python-pytest-benchmark. It should be in file called conftest.py, or in something that is imported into the module containing the test. to your account. For backward compatibility fixtures that produce a path may still return string paths, but this support will be dropped in a future version.

For testing purposes we can reduce the inventory limit to 10. but on the other hand, if you inject this values "magically" it can have opposite effect, maybe some name clashes or other conflicts or unwanted behaviour (not sure only guessing) or you think it won't be a problem? The exception is: If manual scenario discovery is used the problem is the same. On finding it, the fixture method is invoked and the result is returned to the input argument of the test.
