Import restrictions on test modules by nccatoni · Pull Request #7408 · DataDog/system-tests

nccatoni · 2026-07-29T08:04:20Z

Motivation

Restricting imports in test modules makes it possible to enforce certain system-test usage patterns that would otherwise require manual review. There are currently two targeted patterns:

Preventing imports across test modules.
Restricting pytest imports to a limited feature set, notably to prevent the use of native pytest decorators instead of the framework-provided decorators.

Workflow

⚠️ Create your PR as draft ⚠️
Work on you PR until the CI passes
Mark it as ready for review
- Test logic is modified? -> Get a review from RFC owner.
- Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed and the CI green, you can merge it!
