condition-based-waiting

Replace arbitrary delays with condition-based waiting to fix flaky tests. Instead of setTimeout, use a waitFor pattern that polls a condition until it's satisfied or times out, eliminating race conditions and inconsistent pass/fail behavior across CI environments.

Implement condition-based waiting with configurable timeout and polling intervals. This approach re-evaluates your condition continuously rather than guessing a fixed delay, making tests reliable across multi-threaded and parallel environments.

Yes. Condition-based waiting provides clear timeout errors compatible with common JavaScript and TypeScript test runners, making it straightforward to integrate into existing test suites and get meaningful failure messages.

Timing dependencies and race conditions cause flakiness across environments. Condition-based waiting stabilizes tests by replacing fixed delays with actual condition checks, ensuring consistent behavior whether tests run locally or in parallel CI pipelines.

Use the waitFor pattern for React components to wait until DOM elements render or state updates complete. Condition-based waiting eliminates guessing timeouts and aligns with React Testing Library best practices for reliable component testing.
