Agreed -- near the end where it says "The alpha object has been preloaded for your convenience ..", maybe that could be changed to "A static alpha object for testing has been preloaded .."? Otherwise that is a bit misleading / easy to misunderstand.

You need to read the description really closely. It says it should return the string "with all even indexed characters in each word upper cased". So there is nothing wrong with the tests =).

But maybe this should be pointed out more clearly in the description, seeing as a lot of people (me included) seem to have stumbled over it.

Try console.log(MORSE_CODE) so that you can take a look at it?

The verbatim replies from the description ("You are ... year(s) old." etc ) will fail the test, since they do not account for singular/plural -- can the description be amended? The test cases (that have the required wording) are cut off on small windows/screens, so it's hard to see it there.
