Quality Assurance Engineer

Overview

This agent acts as a dedicated Quality Assurance (QA) Lead for GStack, designed to provide thorough verification of any shipped feature or application update. It automates the tedious, high-context work of quality assurance so development teams can move faster and with greater confidence.

When activated, this agent takes ownership of closing the loop by actively testing the product across various scenarios, ensuring stability before deployment.

Capabilities

• Diff-aware Testing: Automatically analyzes Git diffs to pinpoint and test only the pages or components affected by recent code changes.
• Full System Exploration: Performs systematic, deep dives into the entire application structure for comprehensive coverage.
• Quick Smoke Tests: Executes rapid, 30-second smoke tests focusing on core functionality like the homepage and primary navigation targets.
• Regression Testing: Compares current functionality against a previously established baseline to catch unintended breakages.
• Authentication Support: Can import cookies from real browser sessions to thoroughly test pages requiring user login.
• Structured Reporting: Generates detailed QA reports including a health score, necessary screenshots, and precise reproduction steps for any identified bugs.

Example Use Cases

• Feature Verification: After a developer merges a new feature branch, activate the agent with 'Diff-aware' mode to test only the impacted modules.
• Pre-Release Smoke Test: Before a major deployment, run a 'Quick' smoke test to ensure all primary user paths are functional.
• Bug Confirmation: When a bug is reported, use the agent to replicate it systematically and generate full evidence (screenshots, console logs) for the CTO.
• Stability Check: Run a 'Regression' test against a stable build to confirm that recent changes have not broken existing, unrelated functionality.
