I am writing some tests using pytest many of which have similar fixtures. I want to put these "global" fixtures in a single file so that they can be reused across multiple test files. My first thought was to create a fixtures.py file such as
import pytest
@pytest.fixture()
def my_fixture():
# do something
Now how do I use this fixture in my_tests.py?
def test_connect(my_fixture):
pass
This gives fixture 'my_fixture' not found. I can from fixtures import my_fixture. What is the suggested solution to this situation?

A fixture can use multiple other fixtures. Just like a test method can take multiple fixtures as arguments, a fixture can take multiple other fixtures as arguments and use them to create the fixture value that it returns.
Pytest only caches one instance of a fixture at a time, which means that when using a parametrized fixture, pytest may invoke a fixture more than once in the given scope.
Use Pytest Fixtures Across Multiple Test Files With conftest.py. To make it easier on ourselves, we can define a fixture to use across multiple test files. These fixtures are defined by creating a file called conftest.py. Additionally, we can call separate files that also import the fixture from our configuration file.
Fixtures with scope session will only be executed once per session. Every time you run pytest , it's considered to be one session.
Pytest will share the fixtures in conftest.py automatically. Move the shared fixture from fixtures.py to conftest.py.
