I'm going to suggest: "... for IPE's policy parser."

Also, aside from the policy parser tests, are there any other IPE
functional tests?  We do have a testing guideline for new LSM
submissions:

 "New LSMs must be accompanied by a test suite to verify basic
  functionality and help identify regressions. The test suite
  must be publicly available without download restrictions
  requiring accounts, subscriptions, etc. Test coverage does
  not need to reach a specific percentage, but core functionality
  and any user interfaces should be well covered by the test
  suite. Maintaining the test suite in a public git repository is
  preferable over tarball snapshots. Integrating the test suite
  with existing automated Linux kernel testing services is
  encouraged."
