Args:
mocker (MockerFixture): Pytest mocker fixture.

!!! info "About `_extracted_gof_from_results` mock"
This test is not a real test. It is just a mock to get the coverage
up. The test is not really necessary, because the function is just
a wrapper for the print function. The print function is tested
in the test of the report module.

The mock-up is realized with the `mocker` fixture. The mocker fixture
is an extension and `built-in` pytest fixture. It is used to mock
functions and classes.

Mockup over `lmfit` is necessary for the test, because the `results` and
`params` attributes have to be defined.
