Eliminates flaky test failures by replacing arbitrary timeouts with intelligent, condition-based polling logic.
This skill provides Claude with standardized patterns to handle asynchronous operations in testing by waiting for specific state changes rather than relying on fixed delays. By implementing polling mechanisms for events, states, and counts, it resolves race conditions, speeds up CI/CD pipelines, and ensures consistent test outcomes across different hardware and environments. It includes guidance on when to poll, how to structure timeouts, and how to properly document cases where arbitrary delays are actually required.
Key Features
01Includes safety mechanisms like polling intervals and descriptive timeout errors
02Replaces hardcoded sleep and setTimeout with smart polling logic

043 GitHub stars
05Provides generic waitFor implementations with customizable timeout thresholds
06Supports specific patterns for event counts, file existence, and complex state logic
Use Cases
01Optimizing test execution speed by proceeding immediately once conditions are met
02Ensuring asynchronous operations are fully complete before asserting test results
03Fixing flaky integration tests that fail intermittently in CI/CD environments
