condition-based-waiting

You can eliminate flaky tests by replacing arbitrary delays with a condition-based waiting mechanism that polls until the desired state is reached. This provides reliable testing in CI and local environments.

Condition-based polling is a waitFor utility that continuously checks until a state becomes true, replacing fixed delays. It handles asynchronous operations by polling with a configurable timeout and clear error messaging.

Yes, the waitFor mechanism applies to unit, integration, and end-to-end tests. It handles both synchronous and asynchronous operations, providing unified timeout handling and clear errors across all test types.

You can configure timeout handling by setting a specific duration, such as a 5-second timeout, when calling the waitFor utility. It polls the condition until true or throws a clear error if the timeout is exceeded.

The best way to wait for a state is using a condition-based waiting utility like waitFor(() => state === 'ready'). This approach polls dynamically rather than sleeping for arbitrary durations, reducing flakiness.

Your polling utility fails because the condition did not become true within the configured timeout. The condition-based waiting mechanism provides clear error messaging to help diagnose why the desired state was not reached in time.
