parse test METADATA

Error message

parse test METADATA

What it means

Test-helper assertion in metadata_from: parsing the METADATA file of a discovered wheel must succeed so its form fields can be asserted. Fires only if the fixture wheel's METADATA is malformed or the metadata parser regresses.

Solutions

  1. Regenerate the test wheel fixture with a valid METADATA file
  2. Check the metadata parser for regressions with the fixture input
  3. Treat failure as a test-infrastructure issue, not a runtime error
Defensive patterns

Strategy: validation
