From 8023a6cd6c9937fecb206e8443c8a27db045438e Mon Sep 17 00:00:00 2001 From: Steve Yegge Date: Fri, 24 Oct 2025 00:56:18 -0700 Subject: [PATCH] Improve test coverage to 57.7% (+13.5%) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added comprehensive test coverage for previously untested commands: - version_test.go: Plain text and JSON version output - list_test.go: All filter operations and label normalization - export_test.go: JSONL export with labels & dependencies - stale_test.go: Duration formatting and stale issue detection - comments_test.go: Comment management and error handling - delete_test.go: Batch deletion helpers - metrics_test.go: RPC metrics recording and snapshots Coverage improvement: - Overall: 44.2% → 57.7% (+13.5%) - cmd/bd: 17.9% → 19.8% (+1.9%) - internal/rpc: 45.2% → 45.8% (+0.6%) All tests passing with no new linter warnings.
