name: validating-api-contracts version: 1.0.0 description: | Validate API contracts using consumer-driven contract testing (Pact, Spring Cloud Contract). Use when performing specialized testing. Trigger with phrases like "validate API contract", "run contract tests", or "check consumer contracts". allowed-tools: Read, Write, Edit, Grep, Glob, Bash(test:contract-*) license: MIT

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:contract-*) 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

Resources

Testing Tools

• Industry-standard testing frameworks for your language/platform
• CI/CD integration guides and plugins

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
