PYTEST - Is it possible to create the same fixtures more than one time?

Question

I have some parameters coming from a JSON file, and some fixtures in my conftest.py

I would like to iterate all the option scenarios from my list and create my fixtures each time accordingly.

I know that I can use the "params" option in the @pytest.fixture definition but this option doesn't appropriate to cover my specific scenarios.

For example:

I have two parameters in two scenarios (servers come from the same level of the JSON file):

scenario number one:

servers = ["path1", "path2"]

users = [("user_name1", "pw1"), ("user_name2", "pw2")] 

scenario number two:

servers = ["path3"]

users = [("user_name3", "pw3")] 

   

If I transfer to @pytest.fixture(params = [["path1", "path2","path3"])

and to another @pytest.fixture(params = [("user_name1", "pw1"), ("user_name2", "pw2"), ("user_name3", "pw3")]

I will collect 9 tests and I would like to collect only 3 tests (2 tests from the above first scenario and 1 test from the above second scenario.

I tried to iterate in my conftest.py and read each level from my Json file and I succeeded to reach all my three options ( If I print them I received three messages).

The problem is that I can not succeeded to create my two fixtures more than one time.

Pytest take only the last scenario option and collect only 1 test.

Pytest doesn't allowed to iterate and create fixtures dynamically.

Do you know how to fix it?
