condition-based-waiting

Replace arbitrary timeouts with condition-based waiting that polls for actual state changes. Instead of guessing how long async operations take, wait for specific conditions—events, state changes, or counts—to complete reliably across different environments.

Use condition polling with a configurable timeout and predicate-driven checks. Define conditions that represent completion (file written, event fired, count reached) rather than fixed delays, eliminating race conditions that cause inconsistent test failures.

Yes. Condition-based waiting supports patterns like wait-for-event, wait-for-state, wait-for-count, and custom predicates. This lets you monitor actual system behavior instead of relying on timing guesses in async systems.

Timing dependencies cause failures when test environments have different performance characteristics. Condition-based waiting removes this variability by checking for actual completion signals, making tests pass consistently regardless of execution speed.

Use a generic poll-based waitFor utility that accepts a predicate function and timeout. The utility repeatedly checks your condition until it's true or the timeout expires, supporting patterns for files, events, counts, and any custom logic you define.

Yes. Condition-based waiting applies to unit tests with async dependencies and integration tests with race conditions. It replaces timing-dependent patterns across any test level where async operations or timing variability causes flakiness.
