Worked on the PostgREST/postgrest repository to refactor the test suite, focusing on improving readability and maintainability without altering test behavior. Applied Python and pytest to modernize test files, removing unused variables, clarifying exception handling, and simplifying function definitions. Ensured full lint compliance by replacing star imports with explicit imports, addressing Ruff linter requirements and reducing linting noise. The approach emphasized code quality and maintainable testing practices, resulting in cleaner, more understandable test code. No API changes were introduced, and all existing test behaviors were preserved, demonstrating a careful balance between modernization and stability in Python testing workflows.
