impl LSP: Navigation support for pytest fixtures #1901 #2075

asukaminato0721 · 2026-01-12T13:13:27Z

Summary

Fixes #1901

Implemented pytest import/alias detection plus fixture discovery and parameter scanning in pyrefly/lib/state/lsp.rs, and hooked it into go‑to‑definition and local references.

todo: should these pytest functions in their own mod?

Pull request overview

This PR implements LSP navigation support for pytest fixtures, enabling go-to-definition and find-references functionality for fixture parameters in test functions. When a developer invokes go-to-definition on a fixture parameter (e.g., my_fixture in def test_thing(my_fixture):), the LSP will navigate to the fixture definition. Similarly, finding references on a fixture definition will include all test/fixture functions that use it as a parameter.

Changes:

Added pytest import and fixture detection logic to identify pytest modules and fixture decorators
Implemented fixture discovery and parameter scanning to collect fixture definitions and their usage in test functions
Integrated pytest fixture resolution into LSP go-to-definition and find-references operations

for sure. maybe a pyrefly/lib/third_party or something similar?

A more high level comment/question is, do we want to add type support? or is this exclusively an IDE feature? For example, it would be great if the following worked:

from typing import reveal_type import pytest @pytest.fixture def my_fixture() -> int: return 42 def test_foo(my_fixture): reveal_type(my_fixture) # int

That would require extending the binding layer.

Additionally, how would conftest.py fit into this support? Overall, I think there are some open questions when it comes to this feature.

On a different note, I would also say that attr support could be a nice problem to look at (if you are specifically interested in 3p support!)

do we want to add type support

#2201 I think it's here?

I was thinking more like what we're doing for pydantic and django in the binding layer. Was curious why we didn't follow that direction.

Pytest fixtures here are only used to improve navigation (definition/refs) in the LSP, not typing.

The LSP path already has AST access and is allowed to do local scans. Avoiding extra binding state keeps the feature isolated

For now, it’s a tradeoff compared to adding new binding data structures and incremental update logic.

And add typing will be too big for a single pr?

thanks for the improvements! the diff is looking much better. Let me discuss with the team those tradeoffs.

I discussed with the team. I think this tradeoff between storing data in the binding layer vs the lsp layer is still open. We need to better understand the perf implications of this.

now it bind to types
