## Parameterize the instance

And now, we can use `__init__` to declare the parameters of the instance that we can use to "parameterize" the dependency:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[9] *}

 *     instance of G should somehow provide an instance of the class under test, plus any other
 *     information required to parameterize the test.
