# playwright-test [](https://www.npmjs.com/package/playwright-test) [](https://www.npmjs.com/package/playwright-test) [](https://www.npmjs.com/package/playwright-test) 
> Run mocha, zora, uvu, tape and benchmark.js scripts inside real browsers with `playwright`.
## Install
```shell
pnpm install playwright-test
```
## Usage
```shell
playwright-test [files] [options]
# or
pw-test [files] [options]
```
## Options
```shell
Description
Run mocha, zora, uvu, tape and benchmark.js scripts inside real browsers with `playwright` and in Node.
Usage
$ playwright-test [files] [options]
Options
-r, --runner Test runner. Options: mocha, tape, zora, uvu, none, taps and benchmark. Internal runners are autodetected by default. It also accepts a path to a module or a module ID that exports a `playwrightTestRunner` object.
-b, --browser Browser to run tests. Options: chromium, firefox, webkit. (default chromium)
-m, --mode Run mode. Options: main, worker and node. (default main)
-d, --debug Debug mode, keeps browser window open. (default false)
-w, --watch Watch files for changes and re-run tests.
-i, --incognito Use incognito window to run tests. (default false)
-e, --extension Use extension background_page to run tests. (default false)
--cov Enable code coverage in istanbul format. Outputs '.nyc_output/coverage-pw.json'. (default false)
--report-dir Where to output code coverage in instanbul format. (default .nyc_output)
--before Path to a script to be loaded on a separate tab before the main script.
--sw Path to a script to be loaded in a service worker.
--assets Folder with assets to be served by the http server. (default process.cwd())
--cwd Current directory. (default /Users/hd/code/playwright-test)
--extensions File extensions allowed in the bundle. (default js,cjs,mjs,ts,tsx)
--config Path to the config file
-v, --version Displays current version
-h, --help Displays this message
Examples
$ playwright-test test.js --runner tape
$ playwright-test test --debug
$ playwright-test "test/**/*.spec.js" --browser webkit --mode worker --incognito --debug
$ playwright-test bench.js --runner benchmark
# Uses benchmark.js to run your benchmark see playwright-test/mocks/benchmark.js for an example.
$ playwright-test test --cov && npx nyc report --reporter=html
# Enable code coverage in istanbul format which can be used by nyc.
$ playwright-test "test/**/*.spec.js" --debug --before ./mocks/before.js
# Run a script in a separate tab. Check ./mocks/before.js for an example.
# Important: You need to call `self.PW_TEST.beforeEnd()` to start the main script.
Runner Options
All arguments passed to the cli not listed above will be fowarded to the runner.
$ playwright-test test.js --runner mocha --bail --grep 'should fail'
To send a `false` flag use --no-bail.
Check https://mochajs.org/api/mocha for `mocha` options or `npx mocha --help`.
Notes
DEBUG env var filtering for 'debug' package logging will work as expected.
$ DEBUG:app playwright-test test.js
Do not let your shell expand globs, always wrap them.
$ playwright-test "test/**" GOOD
$ playwright-test test/** BAD
```
## Client
This client package exposes the `playwright-test` options and some Playwright browser context methods to be used in tests.
```ts
import * as Client from 'playwright-test/client'
it('should setoffline', async () => {
if (Client.mode === 'main' && Client.options.extension === false) {
globalThis.addEventListener('offline', () => {
console.log('offlineee')
})
await Client.context.setOffline(true)
equal(navigator.onLine, false)
await Client.context.setOffline(false)
equal(navigator.onLine, true)
}
})
it('should geolocation', async () => {
if (Client.mode === 'main') {
const deferred = pdefer()
await Client.context.setGeolocation({
latitude: 59.95,
longitude: 30.316_67,
})
await Client.context.grantPermissions(['geolocation'])
navigator.geolocation.getCurrentPosition((position) => {
deferred.resolve(position)
})
const position = (await deferred.promise) as GeolocationPosition
equal(position.coords.latitude, 59.95)
}
})
```
## Flow control
All test runners support automatic flow control, which means you don't need to call special function or trigger any event in your tests to stop the run. The `none` runner does not support flow control.
To manually stop the run you can use `process.exit`:
```js
process.exit(0) // stops the run and exits with success
process.exit(1) // stops the run and exits with failure
```
## Custom test runner
You can define a custom test runner by passing a path to a file or a node module id that exports an object called `playwrightTestRunner` that implements the `TestRunner` interface.
```shell
$ playwright-test test.js --runner ./my-runner.js
# or
$ playwright-test test.js --runner my-runner
```
You can also just define you test runner in the config file.
```js
// playwright-test.config.js
/** @type {import('../src/runner.js').RunnerOptions} */
const config = {
testRunner: {
compileRuntime: (options, paths) => {
return `
import mocha from 'mocha/mocha.js'
mocha.setup({
reporter: 'spec',
timeout: 5000,
ui: 'bdd',
})
${paths.map((url) => `await import('${url}')`).join('\n')}
mocha
.run((f) =>{
process.exit(f)
})
`
},
},
}
export default config
```
````ts
export interface TestRunner {
/**
* Module ID name used to import the test runner runtime.
* Used in auto detection of the test runner.
*/
moduleId: string
/**
* Options made available to the compiled runtime.
* This is useful to pass options to the test runner.
*
* @example
* ```js
* const options = JSON.parse(process.env.PW_OPTIONS)
* const testRunnerOptions = options.testRunner.options
* ```
*/
options?: unknown
/**
* Esbuild config for the test runner
*/
buildConfig?: BuildOptions
/**
* Compile runtime entry point for esbuild
*
* @param options - Runner options
* @param testPaths - Test paths
* @returns
*/
compileRuntime: (options: RunnerOptions, testPaths: string[]) => string
}
````
## Config
> The config file needs to be commonjs for now, so if your package is pure ESM you need to use `.cjs` extension.
Configuration can be done with cli flags or config files.
```text
package.json, // using property `pw-test` or `playwright-test`
.playwright-testrc.json,
.playwright-testrc.js,
.playwright-testrc.cjs,
playwright-test.config.js,
playwright-test.config.cjs,
.pw-testrc.json,
.pw-testrc.js,
.pw-testrc.cjs,
pw-test.config.js,
pw-test.config.cjs,
.config/playwright-testrc.json
.config/playwright-testrc.js
.config/playwright-testrc.cjs
.config/pw-testrc.json
.config/pw-testrc.js
.config/pw-testrc.cjs
```
The config type can be imported from the entrypoint.
```ts
/** @type {import('playwright-test').RunnerOptions} */
const config = {
// ...
}
export default config
```
The config file can also export a function that receives the cli options as argument.
```ts
/** @type {import('playwright-test').ConfigFn} */
function buildConfig(cliOptions) {
return {
buildConfig: {
bundle: cliOptions.mode !== 'node',
},
}
}
export default buildConfig
```
### Interface
```ts
export interface RunnerOptions {
input?: string[]
testRunner: TestRunner
cwd: string
extensions: string
browser: 'chromium' | 'firefox' | 'webkit'
debug: boolean
mode: 'main' | 'worker' | 'node'
incognito: boolean
extension: boolean
assets: string
before?: string
sw?: string
cov: boolean
reportDir: string
buildConfig: BuildOptions
buildSWConfig: BuildOptions
browserContextOptions?: BrowserContextOptions
beforeTests: (opts: RunnerOptions) => Promise
afterTests: (
opts: RunnerOptions,
beforeTestsOutput: unknown
) => Promise
}
```
