Does this skill work with any testing framework?

Yes, the patterns provided are generic async/await implementations that work across various languages and frameworks, including Vitest, Jest, Playwright, and others.

What happens if a condition is never met?

To prevent infinite loops, the implementation includes a mandatory timeout (defaulting to 5000ms) that throws a clear error message explaining exactly what the test was waiting for before it failed.

Why is condition polling better than using sleep() or setTimeout()?

Sleep functions wait for a fixed duration regardless of when the task finishes. Condition polling checks for the actual state change and continues the test as soon as it's detected, making tests both faster and more reliable.

Will frequent polling slow down my test environment?

The skill utilizes a recommended 10ms polling interval. This provides a high-resolution check that is fast enough for most tests without causing significant CPU overhead or resource contention.

セキュリティとテスト

Eliminates flaky tests by replacing arbitrary timeouts with smart condition polling to ensure reliable and fast async operations.

概要

This skill provides a robust framework for handling asynchronous operations in tests without relying on 'magic numbers' or arbitrary sleep intervals. By shifting from static delays to event-driven or state-driven polling, developers can eliminate race conditions, speed up test execution, and ensure consistent results across different environments like local machines and high-load CI/CD pipelines. It includes standardized patterns for waiting on events, state changes, file existence, and complex logical conditions with built-in timeout safeguards to prevent hanging processes.
