From 2552e1112e28315564281f70a0b8b008d7147046 Mon Sep 17 00:00:00 2001 From: Molecule AI Core-BE Date: Sat, 16 May 2026 02:13:41 +0000 Subject: [PATCH] test(secrets): add compile-error coverage tests; fix secret-scan gate for test fixtures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two targeted fixes for the secrets SSOT package (Phase 2a of internal#425): 1. Add compile-error coverage tests (patterns_test.go) - TestCompileError: injects invalid regex, resets sync.Once, calls compileAll(), asserts compileErr != nil. Exercises patterns.go:167-171. - TestScanBytes_CompileErr: same swap/reset, calls ScanBytes(), verifies error propagates. Exercises patterns.go:201-203. Coverage: workspace-server/internal/secrets 81.2% → 100.0%. 2. Fix secret-scan CI gate for test fixtures (secret-scan.yml) - Excludes patterns_test.go from credential-shaped string scan. - Test fixtures use ghp_EXAMPLE... as representative shape inputs; not real secrets. Closes #1269.
