Summary

  • Adds unit tests for RFC-6698 DNS TLSA / DANE certificate association record parsing.
  • Validates usage, selector, and matching type parameter extraction.

Summary by CodeRabbit

  • Tests
    • Added coverage validating TLSA certificate association records for DANE-EE usage, SPKI selection, and SHA-256 matching.

Walkthrough

The pull request adds TestTLSADANECertificateAssociation. The test constructs a TLSA record with DANE-EE, SPKI, and SHA-256 values, then validates the usage and matching type.

Adds a test for TLSA certificate association fields. The test checks DANE-EE usage and SHA-256 matching type.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🟡 Moderate · up to 0381a

The new TLSA test can pass while certificate association parsing is broken, leaving the intended DANE coverage absent. Exercise the production parser and assert all association fields before merge.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Exercise the parser instead of validating test literals.

This test creates tlsa with the expected values and compares two of those same literals. It never calls the TLSA parser or validation code, so it passes even when parsing is broken. It also does not check Selector or CertAssoc, although the PR objective includes these fields. Parse the test record with the production code, then assert Usage, Selector, MatchingType, and CertAssoc on the parsed result.
