📝 Walkthrough

Walkthrough

The test file muxer/muxer_test.go is refactored to replace a custom containsString helper function with direct calls to the standard library's strings.Contains function. Three error assertion checks are updated to use this approach, and the helper function is subsequently removed from the file.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Verify all three error-check helpers were consistently replaced with strings.Contains calls
• Confirm the containsString helper function is fully removed and not referenced elsewhere in the test file
• Check that the refactored assertions maintain the same error validation logic and intent

480-480: LGTM! Good simplification.

Replacing the custom containsString helper with the standard library's strings.Contains is more idiomatic and reduces unnecessary abstraction.
