Snapshot Test Manager

This skill provides automated assistance for snapshot test manager 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:snapshot-*) 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
