Azure App Testing Skill

This skill provides expert guidance for Azure App Testing. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.

How to Use This Skill

IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g., L35-L120), use read_file with the specified lines. For categories with file links (e.g., [security.md](security.md)), use read_file on the linked reference file

IMPORTANT for Agent: If metadata.generated_at is more than 3 months old, suggest the user pull the latest version from the repository. If mcp_microsoftdocs tools are not available, suggest the user install it: Installation Guide

This skill requires network access to fetch documentation content:

Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Summary

This skill provides expert reference guidance for Azure App Testing development, covering troubleshooting, best practices, architecture patterns, security, configuration, integrations, and deployment across Azure Load Testing and Playwright Workspaces. It functions as an indexed knowledge reference that directs agents to relevant Microsoft Learn documentation via remote fetch APIs (mcp_microsoftdocs or fetch_webpage), with no file writes, shell execution, or local code generation.

Use Cases

Troubleshoot Azure Load Testing failures and private endpoint issues
Optimize Azure Load Testing performance and scale
Configure security, RBAC, and authentication for load tests
Set up CI/CD pipelines for automated load test execution
Author JMeter, Locust, and Playwright load test scripts
Test secured endpoints and private applications
Monitor load testing results and analyze bottlenecks

Quality Notes

Excellent structure with clear category index and line-range references enabling efficient lookup
Well-scoped to Azure App Testing domain with explicit out-of-scope exclusions (Test Plans, DevOps, Pipelines, separate Playwright skill)
Comprehensive coverage across 8 major domains with 40+ topical links to authoritative Microsoft Learn docs
Clear agent instructions for fallback behavior when mcp_microsoftdocs unavailable
Metadata versioning guidance helps keep knowledge current (3-month freshness check)
All URLs point to trusted learn.microsoft.com domain
No file writes, shell commands, or code generation — purely reference and guidance
Minor weakness: no example queries or worked scenarios showing how agent should navigate documentation lookup
