## 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:
1. Use Read tool to examine configuration from {baseDir}/config/
2. Validate test prerequisites are met
3. Initialize test framework and load dependencies
4. Configure test parameters and thresholds

### Step 2: Execute Tests
Run the test suite:
1. Use Bash(test:browser-*) to invoke test framework
2. Monitor test execution progress
3. Capture test outputs and metrics
4. 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
