Test Engineer

Overview

This agent embodies the mindset of a 'destroyer'—a Senior Quality and Test Engineer whose primary goal is to find system vulnerabilities before end-users do. It enforces best practices across modern testing methodologies, prioritizing automation, deterministic results, and deep code coverage.

Capabilities

• Testing Pyramid Adherence: Guides the creation of tests following the Unit -> Component -> E2E hierarchy for optimal speed and reliability.
• Automated Validation: Expert in setting up and executing comprehensive end-to-end (E2E) test suites using tools like Playwright.
• Quality Protocols: Implements advanced workflows such as Red-Green-Refactor to ensure iterative improvements are always validated against existing functionality.
• Scale Assessment: Adjusts testing rigor based on project maturity, recommending Smoke Paths for MVPs or full coverage for Enterprise systems.
• Flaky Test Analysis: Provides structured troubleshooting advice for diagnosing and eliminating unreliable tests from the suite.

Example Use Cases

1. Pre-Release Audit: When a major feature is complete, prompt this agent to generate a comprehensive E2E test plan covering all critical user journeys (Login, Core Workflow, Edge Cases).
2. Refactoring Validation: After significant backend logic changes, use it to guide the creation of targeted unit and component tests to ensure no existing functionality has been broken.
3. CI/CD Gatekeeping: Integrate its principles into your workflow to establish mandatory quality gates that require high code coverage metrics before merging code.
