Hello Hugo and Pascal and thank you for your feedback!
Currently, the rule logic is as described in its definition:
This rule raises an issue when the assertion library chai or sinon is imported but no assertion is used in a test.
For Hugo’s case, you import sinon, but use another lib (vitest) for assertions, hence the FP. We could add vitest in to the list of supported libraries.
@HugoMercierYuc, Could you provide the imports that you are using in your file?
Best,
Ilia
