How does this skill handle operations that never complete?

It implements a mandatory timeout mechanism that fails the test with a clear, descriptive error if the condition is not met within a specific period, preventing infinite loops.

Can I use this for browser or UI testing?

Yes, it is ideal for waiting for DOM elements, state changes, or API responses in browser-based automation and integration tests where timing is often inconsistent.

Does polling waste CPU resources during the test run?

No, the implementation uses a 10ms poll interval to perfectly balance responsiveness with CPU efficiency, avoiding the overhead of a tight loop while maintaining speed.

Why is condition-based waiting better than sleep or setTimeout?

Arbitrary sleeps make tests unnecessarily slow and unreliable; condition-based waiting proceeds as soon as the specific state is reached, making tests both faster and significantly more stable.

セキュリティとテスト

Eliminates flaky tests and race conditions by replacing arbitrary timeouts with smart condition polling.

概要

This skill provides a systematic approach to handling asynchronous operations in testing by moving away from unreliable timing guesses. It introduces standardized patterns for waiting for actual state changes, specific events, or file system updates using a generic polling mechanism with built-in timeout protection. By focusing on actual conditions rather than fixed delays, developers can ensure their tests are resilient across different environments—from local development to high-load CI pipelines—resulting in faster execution times and consistent pass rates.
