How does the exponential backoff feature work?

It provides a pattern that starts with frequent checks and gradually increases the wait interval, balancing the need for quick response times with system resource conservation.

Why is condition polling better than using setTimeout?

setTimeout uses a 'best guess' for timing, which leads to failures on slower machines or under load. Condition polling checks for actual state completion, making tests both faster and more reliable.

Does this skill help with CI/CD failures?

Yes, it is specifically designed to eliminate 'it works on my machine' bugs by ensuring tests wait for the exact condition required to pass, regardless of the execution environment's speed.

When should I avoid using polling?

Polling should be avoided when native event-based systems are available, such as WebSockets, EventEmitters, DOM events, or standard async/await Promises.

セキュリティとテスト

Eliminates flaky tests by replacing arbitrary timeouts with intelligent condition polling and event-driven waiting patterns.

概要

Condition-Based Waiting is a specialized skill designed to solve the common problem of race conditions and inconsistent test behavior in asynchronous environments. It provides structured patterns for moving away from brittle 'sleep' or 'setTimeout' calls toward robust polling and event-based mechanisms. By ensuring that code only proceeds when specific criteria are met—rather than guessing at timing—this skill helps developers create reliable test suites that perform consistently across local machines and high-load CI/CD pipelines.
