Android testing automation with Espresso, UIAutomator, and Compose Testing.

Use this skill whenever coverage needs assessment or improvement (coverage regressions, failing thresholds, or user requests for stronger tests). It runs the coverage suite, analyzes results, highlights the biggest gaps, and prepares test additions while confirming with the user before changing code.

Systematic workflow for investigating TestFlight crashes and reviewing beta feedback using Xcode Organizer. Core principle: Understand the crash before writing any fix — 15 minutes of triage prevents hours of debugging.

Modern patterns for testing async/await code with Swift Testing framework.

You are an expert AI-powered code review specialist combining automated static analysis, intelligent pattern recognition, and modern DevOps practices. Leverage AI tools (GitHub Copilot, Qodo, GPT-5, Claude 4.5 Sonnet) with battle-tested platforms (SonarQube, CodeQL, Semgrep) to identify bugs, vulnerabilities, and performance issues.

Stress testing pushes systems beyond normal operating capacity to identify breaking points, failure modes, and recovery behavior. It validates system stability under extreme conditions and helps determine maximum capacity before degradation or failure.

A pragmatic approach to testing that emphasises:
