Question

A backend team has a Python service using pytest with fixtures and parametrization. A developer selects a pure utility function `normalize_phone(raw: str) -> str` and asks Copilot Chat to '/tests generate unit tests for this function'. Copilot returns tests written using Python's built-in `unittest.TestCase` class with `self.assertEqual` assertions instead of pytest idioms. What is the most effective way to get tests that fit the team's existing suite?

Accepted Answer

Refine the prompt to specify the target framework and conventions, e.g., 'Generate pytest tests using parametrize for the input cases and plain assert statements, matching our existing style.'

Answer

Accept the unittest-based tests as-is, since Copilot chose a valid Python testing framework and both frameworks can coexist.

Answer

Reject test generation for this function and write the tests manually, because Copilot cannot produce pytest-style tests.

Answer

Rename the function to include the word 'pytest' so Copilot infers the correct framework from the symbol name.
