AVA is a fast and simple JavaScript test runner with builtin support for ES2015.

Description

Even though JavaScript is single-threaded, IO in Node.js can happen in parallel due to its async nature. AVA takes advantage of this and runs your tests concurrently, which is especially beneficial for IO heavy tests. In addition, test files are run in parallel as separate processes, giving you even better performance and an isolated environment for each test file.

Highlights

  • Minimal and fast
  • Simple test syntax
  • Runs tests concurrently
  • Enforces writing atomic tests
  • No implicit globals
  • Isolated environment for each test file
  • Write your tests in ES2015
  • Promise support
  • Generator function support
  • Async function support
  • Observable support
  • Enhanced asserts
  • Optional TAP output
  • Clean stack traces

Example test syntax

import test from 'ava';

test(t => {
    t.is(foo(), 'foo');
});
