AVA is a minimalist test runner for Node.js with a concise API, detailed error output, and concurrent test execution in isolated worker threads. It supports async/await, promises, observables, TypeScript, and includes a watch mode and TAP reporter.

Use cases

• run unit tests for a node.js project
• run tests concurrently for faster feedback
• write async tests with promises and async functions
• watch files and rerun tests on change
• get detailed assertion failure output
• run tests in parallel in CI
• test typescript code without extra config

When to choose

• you want a fast, minimal test runner for Node.js with concurrent execution
• you prefer atomic tests with no implicit globals
• you need built-in TypeScript support and enhanced assertion messages
• you want watch mode and TAP output out of the box

When to avoid

• you need browser or DOM testing
• your team relies on a plugin-heavy ecosystem like Jest or Mocha
• you need snapshot testing or mocking beyond what AVA provides natively
• you test non-Node.js runtimes
