Several Glee characters were “tested” in Season 5, Episode 16. Blaine (Darren Criss) and Kurt’s (Chris Colfer) relationship was put to the test when Blaine packed on the Freshman 15 and felt insecure around his fiancé, Sam (Chord Overstreet) was tested by Mercedes (Amber Riley) when she revealed that she was waiting to have sex until after marriage, and Artie (Kevin McHale) was literally tested for an STD and found out he had chlamydia.

Despite the various tests, many of the songs from “Tested” were about love, whether Artie was singing the Robert Palmer classic, “Addicted to Love,” or Blaine was belting out Pat Benetar’s “Love Is a Battlefield.”
