Eliminates flaky tests by replacing arbitrary delays with reliable condition-based polling logic.
This skill provides standardized patterns for handling timing dependencies in automated tests to ensure stability across different environments. Instead of using fragile, fixed timeouts like setTimeout(50), it implements a robust polling mechanism that waits for specific state changes, events, or data availability. It is essential for developers struggling with race conditions, inconsistent CI results, or tests that pass locally but fail under load, ultimately resulting in faster and significantly more reliable test suites.
