Why AVA?

Minimal and fast
Simple test syntax
Runs tests concurrently
Enforces writing atomic tests
No implicit globals
Includes TypeScript definitions
Magic assert
Isolated environment for each test file
Promise support
Async function support
Observable support
Enhanced assertion messages
Automatic parallel test runs in CI
TAP reporter

Usage

To install and set up AVA, run:

1npm init ava

Your package.json will then look like this (exact version notwithstanding):

1{
2	"name": "awesome-package",
3	"type": "module",
4	"scripts": {
5		"test": "ava"
6	},
7	"devDependencies": {
8		"ava": "^5.0.0"
9	}
10}

Or if you prefer using Yarn:

1yarn add ava --dev

Alternatively you can install ava manually:

1npm install --save-dev ava

Make sure to install AVA locally. AVA cannot be run globally.

Don't forget to configure the test script in your package.json as per above.

Create your test file

Create a file named test.js in the project root directory.

Note that AVA's documentation assumes you're using ES modules.

1import test from 'ava';
2
3test('foo', t => {
4	t.pass();
5});
6
7test('bar', async t => {
8	const bar = Promise.resolve('bar');
9	t.is(await bar, 'bar');
10});

Running your tests

1npm test

Or with npx:

1npx ava

Run with the --watch flag to enable AVA's watch mode:

1npx ava --watch

Supported Node.js versions

AVA supports the latest release of any major version that is supported by Node.js itself. Read more in our support statement.

Highlights

Magic assert

AVA adds code excerpts and clean diffs for actual and expected values. If values in the assertion are objects or arrays, only a diff is displayed, to remove the noise and focus on the problem. The diff is syntax-highlighted too! If you are comparing strings, both single and multi line, AVA displays a different kind of output, highlighting the added or missing characters.

Clean stack traces

AVA automatically removes unrelated lines in stack traces, allowing you to find the source of an error much faster, as seen above.

Parallel runs in CI

AVA automatically detects whether your CI environment supports parallel builds. Each build will run a subset of all test files, while still making sure all tests get executed. See the ci-parallel-vars package for a list of supported CI environments.

AVA, not Ava or ava. Pronounced /ˈeɪvə/: Ay (face, made) V (vie, have) A (comma, ago)

What is the header background?

It's the Andromeda galaxy.

What is the difference between concurrency and parallelism?

Concurrency is not parallelism. It enables parallelism.
