SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Flaky tests often rely on arbitrary delays, leading to race conditions and inconsistent results across machines and CI environments.

Core Features & Use Cases

  • waitFor: generic polling with timeout to await a condition.
  • waitForEvent / waitForEventCount / waitForEventMatch: specialized variants for thread/event driven testing.
  • Real-world use: replace timeouts in tests that interact with async operations, events, or delayed responses.

Quick Start

Import and start using waitFor and related helpers in your tests to replace arbitrary delays with condition-based waiting for deterministic results.

FAQPage Schema
How do I fix flaky tests caused by arbitrary delays in asynchronous workflows?

Fix flaky tests by replacing arbitrary delays with condition-based waiting utilities. This introduces a robust polling mechanism with timeouts to await specific conditions, ensuring deterministic test completion across async workflows and events.

What is the best way to wait for a specific event count in TypeScript tests?

Wait for a specific event count using the waitForEventCount helper. This specialized polling variant enforces reliable test completion by checking event conditions against expected thresholds rather than relying on fixed time delays.

How does condition polling work for multi-threaded simulations where timing is nondeterministic?

Condition polling handles nondeterministic timing by continuously checking a condition until it resolves or times out. Utilities like waitFor and waitForEventMatch enforce deterministic test completion in multi-threaded simulations without arbitrary delays.

Can I use these condition-based waiting helpers for both unit and integration tests?

Yes, you can use condition-based waiting helpers for both unit and integration tests. They are specifically applicable across asynchronous workflows, event-driven architectures, and multi-threaded simulations to eliminate race conditions and ensure reliable results.

Why does my test suite fail inconsistently across different machines and CI environments?

Test suites fail inconsistently because arbitrary delays cause race conditions. Replacing fixed timeouts with condition-based waiting utilities ensures tests only proceed when conditions are met, producing deterministic results across varying machine speeds and CI environments.
