Bun ships with a fast built-in test runner. Tests are executed with the Bun runtime, and support the following features. - TypeScript and JSX - Lifecycle hooks - Snapshot testing - UI & DOM testing - Watch mode with `--watch` - Script pre-loading with `--preload` ## Run tests ```bash $ bun test ``` Tests are written in JavaScript or TypeScript with a Jest-like API. Refer to [Writing tests](/docs/test/writing) for full documentation. ```ts#math.test.ts import { expect, test } from "bun:test"; test("2 + 2", () => { expect(2 + 2).toBe(4); }); ``` The runner recursively searches the working directory for files that match the following patterns: - `*.test.{js|jsx|ts|tsx}` - `*_test.{js|jsx|ts|tsx}` - `*.spec.{js|jsx|ts|tsx}` - `*_spec.{js|jsx|ts|tsx}` You can filter the set of tests to run by passing additional positional arguments to `bun test`. Any file in the directory with an _absolute path_ that contains one of the filters will run. Commonly, these filters will be file or directory names; glob patterns are not yet supported. ```bash $ bun test ... ``` The test runner runs all tests in a single process. It loads all `--preload` scripts (see [Lifecycle](/docs/test/lifecycle) for details), then runs all tests. If a test fails, the test runner will exit with a non-zero exit code. ## Watch mode Similar to `bun run`, you can pass the `--watch` flag to `bun test` to watch for changes and re-run tests. ```bash $ bun test --watch ``` ## Lifecycle hooks Bun supports the following lifecycle hooks: | Hook | Description | | ------------ | --------------------------- | | `beforeAll` | Runs once before all tests. | | `beforeEach` | Runs before each test. | | `afterEach` | Runs after each test. | | `afterAll` | Runs once after all tests. | These hooks can be define inside test files, or in a separate file that is preloaded with the `--preload` flag. ```ts $ bun test --preload ./setup.ts ``` See [Test > Lifecycle](/docs/test/lifecycle) for complete documentation. ## Snapshot testing Snapshots are supported by `bun test`. See [Test > Snapshots](/docs/test/snapshots) for complete documentation. ## UI & DOM testing Bun is compatible with popular UI testing libraries: - [HappyDOM](https://github.com/capricorn86/happy-dom) - [DOM Testing Library](https://testing-library.com/docs/dom-testing-library/intro/) - [React Testing Library](https://testing-library.com/docs/react-testing-library/intro) See [Test > DOM Testing](/docs/test/dom) for complete documentation. ## Performance Bun's test runner is fast. {% image src="/images/buntest.jpeg" caption="Running 266 React SSR tests faster than Jest can print its version number." /%} iter'>derrick/fix/event-emitter-async-iter Unnamed repository; edit this file 'description' to name the repository.

2023-08-31`bun install` correctly join dependency URLs (#4421)Gravatar Julian 6-64/+243
* use WTF to join registry strings * show dependency error messages, better join error We actually report errors when enqueuing dependencies now. I also made the join URLs error message read better. It'd be cleaner to handle it all in one place, but there's currently no way to propagate the data up. * starting on registry URL tests * added more registry URL tests * [install] prevent optional/peer deps from failing builds Couldn't get the peer dependency test to work, but the code is there. * ran prettier * changed error note to use realname, updated tests * ran prettier again...
