Test Coverage Analyzer
This skill provides automated assistance for test coverage analyzer tasks.
Prerequisites
Before using this skill, ensure you have:
- Test environment configured and accessible
- Required testing tools and frameworks installed
- Test data and fixtures prepared
- Appropriate permissions for test execution
- Network connectivity if testing external services
Instructions
Step 1: Prepare Test Environment
Set up the testing context:
- Use Read tool to examine configuration from {baseDir}/config/
- Validate test prerequisites are met
- Initialize test framework and load dependencies
- Configure test parameters and thresholds
Step 2: Execute Tests
Run the test suite:
- Use Bash(test:coverage-*) to invoke test framework
- Monitor test execution progress
- Capture test outputs and metrics
- Handle test failures and error conditions
Step 3: Analyze Results
Process test outcomes:
- Identify passed and failed tests
- Calculate success rate and performance metrics
- Detect patterns in failures
- Generate insights for improvement
Step 4: Generate Report
Document findings in {baseDir}/test-reports/:
- Test execution summary
- Detailed failure analysis
- Performance benchmarks
- Recommendations for fixes
Output
The skill generates comprehensive test results:
Test Summary
- Total tests executed
- Pass/fail counts and percentage
- Execution time metrics
- Resource utilization stats
Detailed Results
Each test includes:
- Test name and identifier
- Execution status (pass/fail/skip)
- Actual vs. expected outcomes
- Error messages and stack traces
Metrics and Analysis
- Code coverage percentages
- Performance benchmarks
- Trend analysis across runs
- Quality gate compliance status
Error Handling
Common issues and solutions:
Environment Setup Failures
- Error: Test environment not properly configured
- Solution: Verify configuration files; check environment variables; ensure dependencies are installed
Test Execution Timeouts
- Error: Tests exceeded maximum execution time
- Solution: Increase timeout thresholds; optimize slow tests; parallelize test execution
Resource Exhaustion
- Error: Insufficient memory or disk space during testing
- Solution: Clean up temporary files; reduce concurrent test workers; increase resource allocation
Dependency Issues
- Error: Required services or databases unavailable
- Solution: Verify service health; check network connectivity; use mocks if services are down
Resources
Testing Tools
- Industry-standard testing frameworks for your language/platform
- CI/CD integration guides and plugins
- Test automation best practices documentation
Best Practices
- Maintain test isolation and independence
- Use meaningful test names and descriptions
- Keep tests fast and focused
- Implement proper setup and teardown
- Version control test artifacts
- Run tests in CI/CD pipelines
