Drum Machine project works as required but test fails

Hi all

I am having a bit of a problem with the Drum machine project.
The application works as required based on the user stories supplied, by the test for user story 6 fails for some reason i do not understand.

User Story #6: When I press the trigger key associated with each .drum-pad , the audio clip contained in its child audio element should be triggered (e.g. pressing the Q key should trigger the drum pad which contains the string Q , pressing the W key should trigger the drum pad which contains the string W , etc.).

Here is the link to my codepen.

Drum Machine (codepen.io)

I would greatly appreciate any help on this please.

When I test manually, the sounds only play on “q” and not “Q.” The test sends “Q.”

Thanks Jeremy. That was the issue.
