\n uvu is an extremely fast and lightweight test runner for Node.js and the browser
\n Ultimate Velocity, Unleashed

\n \"example\n
\n\n\n## Features\n\n* Super [lightweight](https://npm.anvaka.com/#!/view/2d/uvu)\n* Extremely [performant](#benchmarks)\n* Individually executable test files\n* Supports `async`/`await` tests\n* Supports native ES Modules\n* Browser-Compatible\n* Familiar API\n\n\n## Install\n\n```\n$ npm install --save-dev uvu\n```\n\n\n## Usage\n\n> Check out [`/examples`](/examples) for a list of working demos!\n\n```js\n// tests/demo.js\nimport { test } from 'uvu';\nimport * as assert from 'uvu/assert';\n\ntest('Math.sqrt()', () => {\n assert.is(Math.sqrt(4), 2);\n assert.is(Math.sqrt(144), 12);\n assert.is(Math.sqrt(2), Math.SQRT2);\n});\n\ntest('JSON', () => {\n const input = {\n foo: 'hello',\n bar: 'world'\n };\n\n const output = JSON.stringify(input);\n\n assert.snapshot(output, `{\"foo\":\"hello\",\"bar\":\"world\"}`);\n assert.equal(JSON.parse(output), input, 'matches original');\n});\n\ntest.run();\n```\n\nThen execute this test file:\n\n```sh\n# via `uvu` cli, for all `/tests/**` files\n$ uvu -r esm tests\n\n# via `node` directly, for file isolation\n$ node -r esm tests/demo.js\n```\n\n> [View the `uvu` CLI documentation](/docs/cli.md)\n\n\n## Assertions\n\nThe [`uvu/assert`](/docs/api.assert.md) module is _completely_ optional.\n\nIn fact, you may use any assertion library, including Node's native [`assert`](https://nodejs.org/api/assert.html) module! This works because `uvu` relies on thrown Errors to detect failures. Implicitly, this also means that any uncaught exceptions and/or unhandled `Promise` rejections will result in a failure, which is what you want!\n\n\n## API\n\n### Module: `uvu`\n\n> [View `uvu` API documentation](/docs/api.uvu.md)\n\nThe main entry from which you will import the `test` or `suite` methods.\n\n### Module: `uvu/assert`\n\n> [View `uvu/assert` API documentation](/docs/api.assert.md)\n\nA collection of assertion methods to use within your tests. Please note that:\n\n* these are browser compatible\n* these are _completely_ optional\n\n\n## Benchmarks\n\n> via the [`/bench`](/bench) directory with Node v10.21.0\n\nBelow you'll find each test runner with two timing values:\n\n* the `took ___` value is the total process execution time – from startup to termination\n* the parenthesis value (`(___)`) is the self-reported execution time, if known\n\nEach test runner's `stdout` is printed to the console to verify all assertions pass.
