From 517350181196f56b1b1e2a04ef5453aa5211173a Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 17 Nov 2025 23:43:00 +0000 Subject: [PATCH 01/12] Add coverage files to .gitignore Analyzed test coverage across the codebase (58.7% overall). Adding coverage output files to .gitignore to prevent them from being accidentally committed. Key findings: - Well-tested: pkg/errors (94.6%), pkg/raw (90.9%) - Gaps: cmd/*, internal/ghmcp (0%), GitHub Actions tools (0%) - Priority improvements needed for server initialization and critical business logic paths --- .gitignore | 2 ++ 1 file changed, 2 insertions(+) diff --git a/.gitignore b/.gitignore index 9cf7e3821..bbf81d4ac 100644 --- a/.gitignore +++ b/.gitignore @@ -12,6 +12,8 @@ __debug_bin* # Go vendor bin/ +*.out +coverage.html # macOS .DS_Store From 929113cf5feec88cd3e777581ce25c7b8a54593d Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 17 Nov 2025 23:57:00 +0000 Subject: [PATCH 02/12] Add comprehensive test coverage for critical infrastructure packages MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Improved overall test coverage from 58.7% to 63.3% (+4.6 percentage points) by adding 1,980 lines of comprehensive tests across 4 critical packages. New test files created: - internal/ghmcp/server_test.go (588 lines) * Server initialization and configuration testing * API host parsing for GitHub.com, GHEC, and GHES * Authentication transport middleware * Read-only mode and dynamic toolsets * Coverage: 0% → 56.2% - internal/profiler/profiler_test.go (572 lines) * Performance profiling functionality * Memory delta calculations with overflow handling * Global and instance profilers * Environment variable configuration * Coverage: 0% → 100% - pkg/buffer/buffer_test.go (328 lines) * Ring buffer implementation for log processing * Small, exact, and large log handling * Overflow scenarios and wraparound logic * Unicode and special character support * Coverage: 0% → 96.2% - pkg/translations/translations_test.go (492 lines) * Translation/i18n system testing * Environment variable and JSON config overrides * Translation key caching * Export functionality * Coverage: 0% → 87.5% Test highlights: - 150+ new test cases with comprehensive edge case coverage - Table-driven tests for parameterized scenarios - Mock implementations for HTTP transports - Concurrent access and error handling scenarios - Integration with testify/assert for cleaner assertions All tests passing across all packages. --- internal/ghmcp/server_test.go | 588 ++++++++++++++++++++++++++ internal/profiler/profiler_test.go | 572

00:00:00 2001 From: Claude Date: Tue, 18 Nov 2025 00:23:19 +0000 Subject: [PATCH 03/12] Add comprehensive tests for dynamic toolsets and workflow prompts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Increased overall coverage from 63.3% to 64.5% (+1.2 percentage points). Added 789 lines of new tests across 2 test files. New test files: - pkg/github/dynamic_tools_test.go (425 lines) * Dynamic toolset management tests * Enable/disable toolset functionality * List available toolsets * Get tools from specific toolsets * Integration tests for toolset workflows * Coverage for dynamic toolset features: 0% → significant improvement - pkg/github/workflow_prompts_test.go (364 lines) * IssueToFixWorkflow prompt testing * Argument validation (owner, repo, title, description) * Optional parameters (labels, assignees) * Special character handling * Message structure validation * Workflow guidance verification * Coverage: workflow_prompts.go 0% → 100% Test highlights: - 30+ test cases for dynamic toolsets - 15+ test cases for workflow prompts - Table-driven tests for multiple scenarios - JSON response parsing and validation - Error handling for missing/invalid toolsets - Integration tests between multiple components Package coverage improvements: - pkg/github: 69.3% → 70.8% (+1.5%) - Overall: 63.3% → 64.5% (+1.2%) All tests passing successfully. --- pkg/github/dynamic_tools_test.go | 425 ++++++++++++++++++++++++++++ pkg/github/workflow_prompts_test.go | 364 ++++++++++++++++++++++++ 2 files changed, 789
