Is it possible to do something like

__defaults__(
    {
        "python_test": {
            "dependencies.add": ["path/to/common/fixtures.py"],
        },
    }
)

Using

python_test_utils

is great for a

conftest

but what about a

conftest

for the entire monorepo? (our monorepo is a collection of directories like

{top-level-project}/src

and

{top-level-project}/tests

)

As long as you have the appropriate

python_test_utils

targets describing your

conftest.py

files, all

conftest.py

files in the same directory or any parent directory of a

python_test

target should be recognized as dependencies automatically. In other words, there should be no need for what you are trying to do. Can you share what your directory structure and BUILD files look like (or a reduced example)?

Thanks @elegant-florist-94385. I ended up just importing shared fixtures into a

conftest

adjacent to the tests that use them. I was able to also get it to work by having a conftest in my root directory with a “pytest_plugin = …“. I think between fighting weird syntax of

__defaults__

and pytest fixture magic I didn’t think clearly enough about what I was actually trying to achieve.

Key thing to remember is that pytest does a lot of "search the filesystem" type stuff, which doesn't always play nice with dependency inference and sandboxes. If you can get the sandbox filesystem to be correct, it will usually work out
