PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
General	Add defensive error handling around file type detection to provide clearer test failures Add error handling around filetype.guess() calls since they could return None for corrupted images or non-image data. This would make the tests more robust. py/test/selenium/webdriver/common/takes_screenshots_tests.py [29-30] kind = filetype.guess(result) -assert kind is not None and kind.mime == "image/png" +if kind is None: + raise AssertionError("Failed to determine file type - image data may be corrupted") +assert kind.mime == "image/png", f"Expected PNG image but got {kind.mime}" Apply this suggestion Suggestion importance[1-10]: 7 Why: The suggestion improves error handling and test diagnostics by providing more specific error messages when image validation fails, making it easier to debug test failures.	7
