Analyzed test coverage of the GitHub MCP Server codebase and identified areas for improvement. Key findings: - Overall coverage: 58.7% - Well-tested packages: pkg/errors (94.6%), pkg/raw (90.9%), pkg/log (81.8%) - Critical gaps: Infrastructure code (server init, profiler, buffer) at 0% - Medium gaps: Translations (0%), dynamic toolsets (0%), toolset mgmt (40%) - GitHub handlers: Good coverage (69%) but missing edge cases Priority recommendations: 1. HIGH: Test infrastructure code (server.go, profiler.go, buffer.go) 2. MEDIUM: Test translations, dynamic toolsets, toolset management 3. MEDIUM: Add edge case tests for GitHub API handlers 4. LOW: CLI tools (covered by e2e tests) Document includes detailed recommendations, test patterns, and a phased implementation plan to reach 75%+ coverage.
Add coverage.out and *.test to .gitignore as these are generated files from running tests and should not be committed to version control.
…ITY) Add tests for three high-priority packages that had 0% coverage: 1. pkg/buffer (0% → 96.2%) - 13 comprehensive test cases for ring buffer logic - Tests empty response, single line, buffer wraparound - Tests edge cases: empty lines, long lines, trailing newlines - Validates correct ordering after ring buffer wraparound 2. internal/profiler (0% → 96.4%) - 20+ test cases covering all profiler functionality - Critical overflow handling tests for safeMemoryDelta - Tests for MaxInt64 boundary conditions - Global profiler initialization and env var parsing - Profiling enabled/disabled scenarios 3. internal/ghmcp (0% → 34.7%) - API host parsing for github.com, GHES, GHEC - Tests URL scheme requirements and validation - Tests for dotcom, GHEC (*.ghe.com), and GHES hosts - Bearer auth and user-agent transport tests - Invalid URL handling Overall Coverage Impact: 58.7% → 62.0% (+3.3 percentage points) These tests provide critical safety nets for: - Ring buffer log tailing (used in job log retrieval) - Memory profiling with overflow protection - Multi-environment API host configuration All tests follow project patterns: table-driven, testify assertions, explicit test names, and comprehensive edge case coverage.
… PRIORITY) Add tests for two medium-priority packages: 1. pkg/translations (0% → 84.4%) - 17 comprehensive test cases for i18n system - Test NullTranslationHelper default behavior - Test TranslationHelper caching and env var overrides - Test case-insensitive keys (all uppercase internally) - Test environment variable precedence (GITHUB_MCP_* prefix) - Test DumpTranslationKeyMap JSON file creation - Test special characters, unicode, empty values - Test cleanup function 2. pkg/github/dynamic_tools.go (0% → 100%) - 11 comprehensive test cases for dynamic toolset discovery - Test EnableToolset success, already enabled, not found - Test ListAvailableToolsets with enabled/disabled status - Test GetToolsetsTools returns correct tool information - Test missing parameters and error handling - Test empty toolsets and toolset groups - Test ToolsetEnum functionality Overall Coverage Impact: 62.0% → 63.3% (+1.3 percentage points) These tests provide coverage for: - User-facing toolset discovery and management - i18n system with environment variable overrides - Dynamic tool enabling workflow All tests follow project patterns and include comprehensive edge cases.
