Always check to make sure your test fails without the change. Because of the way FileCheck works, if you removed --no-params from the command-line, this test would still pass. This is because FileCheck just looks for substrings in the full output. You'll want to add --match-full-lines to your FileCheck arguments, and probably --strict-whitespace too. NB: if you do this, you'll need to remove the space after the colon on these pattern lines.
