Originally the test would check for the index of a title in an array of unique challenge titles. However, the index of the title within the array isn't important for this test, so I simplified the code using @Bouncey's suggestion in PR #17035. Also changed grammar for the error that's thrown when a challenge title isn't a valid string. BREAKING CHANGE: None
