From 058b51f1546d0718423f53b0b4e48b6f369c6fad Mon Sep 17 00:00:00 2001 From: Dave Hubbard <4305408+unsmith@users.noreply.github.com> Date: Thu, 17 Sep 2026 11:22:19 -0400 Subject: [PATCH] tests: add coverage for OAuth2 custom verifier changes TracedTokenSource: - EnrichContext sets oauth2_trace on the context - Token() delegates to the inner token source EndpointSetter OAuth2 methods: - HasOAuth2 false by default, true after SetOAuth2TokenSource - SetOAuth2TokenSource(nil) clears it BuildTokenSource: - nil auth returns nil - unknown auth type returns nil - valid ROPC config returns a TracedTokenSource with a non-empty trace Token endpoint validation: - HTTP token endpoint rejected without unsafe=true - HTTP token endpoint allowed with unsafe=true Inline verification: - verifier struct has token source when auth is configured - verifier struct has nil token source without auth - inline verification works end-to-end without OAuth2 YAML parsing: - auth block with ROPC config round-trips through protoyaml OAuthVerify: - 200 with verified=true - 200 with verified=false - 401 returns error - 200 with invalid JSON returns error - 500 returns error with status code - no endpoints returns error - fallback from failed first endpoint to successful second Co-authored-by: Cursor --- pkg/custom_detectors/custom_detectors_test.go | 383 ++++++++++++++++++
