Can I use this skill for UI testing with Playwright?

Absolutely. It provides specific patterns for spinning up an Aspire-orchestrated environment and connecting a Playwright browser instance to the dynamically assigned endpoints.

Does this skill support testing with real databases?

Yes, the skill focuses on using actual infrastructure like SQL Server and Redis via Aspire's container orchestration rather than relying on mocks or in-memory substitutes.

What is the 'File Watcher Fix' included in the skill?

It provides a ModuleInitializer pattern that disables configuration reloading in test hosts, preventing the 'inotify' file descriptor exhaustion common when running many .NET integration tests on Linux.

How does it prevent port conflicts during parallel testing?

The skill utilizes Aspire's dynamic port binding capabilities (assigning 127.0.0.1:0), allowing multiple test instances to run simultaneously without network contention.

Security & Testing

Streamlines the creation of robust integration tests for distributed .NET applications using the Aspire testing framework and xUnit.

About

This skill provides comprehensive guidance and implementation patterns for testing .NET Aspire applications with real infrastructure dependencies rather than mocks. It automates the setup of distributed application fixtures, manages dynamic endpoint discovery, and ensures proper resource lifecycle handling using xUnit's IAsyncLifetime. Whether you are verifying service-to-service communication, testing with live SQL or Redis containers, or integrating Playwright for UI testing, this skill helps developers build reliable test suites that mirror production environments while solving common hurdles like Linux file descriptor exhaustion.

Key Features

Critical Linux file watcher optimization for high-scale test runners

203 GitHub stars
Real dependency integration for SQL Server, Redis, and message queues
Unified patterns for combining Aspire orchestration with Playwright E2E tests
Dynamic endpoint discovery for distributed microservices

Use Cases

Verifying complex communication patterns between multiple microservices
Executing end-to-end UI tests that require a fully orchestrated backend environment
Running integration tests against live database containers without manual setup
