Playwright

# Playwright

Extends Helper

Uses Playwright (opens new window) library to run tests inside:

  • Chromium
  • Firefox
  • Webkit (Safari)

This helper works with a browser out of the box with no additional tools required to install.

Requires playwright or playwright-core package version ^1 to be installed:

npm i playwright@^1.18 --save

or

npm i playwright-core@^1.18 --save

Breaking Changes: if you use Playwright v1.38 and later, it will no longer download browsers automatically.

Run npx playwright install to download browsers after npm install.

Using playwright-core package, will prevent the download of browser binaries and allow connecting to an existing browser installation or for connecting to a remote one.

# Configuration

This helper should be configured in codecept.conf.(js|ts)

Type: object (opens new window)

# Properties

# Video Recording Customization

By default, video is saved to output/video dir. You can customize this path by passing dir option to recordVideo option.

video: enables video recording for failed tests; videos are saved into output/videos folder

# Trace Recording Customization

Trace recording provides complete information on test execution and includes DOM snapshots, screenshots, and network requests logged during run. Traces will be saved to output/trace

  • trace: enables trace recording for failed tests; trace are saved into output/trace folder
  • keepTraceForPassedTests: - save trace for passed tests

# HAR Recording Customization

A HAR file is an HTTP Archive file that contains a record of all the network requests that are made when a page is loaded. It contains information about the request and response headers, cookies, content, timings, and more. You can use HAR files to mock network requests in your tests. HAR will be saved to output/har. More info could be found here https://playwright.dev/docs/api/class-browser#browser-new-context-option-record-har (opens new window).

...
recordHar: {
    mode: 'minimal', // possible values: 'minimal'|'full'.
    content: 'embed' // possible values:  "omit"|"embed"|"attach".
}
...

# Example #1: Wait for 0 network connections.

{
   helpers: {
     Playwright : {
       url: "http://localhost",
       restart: false,
       waitForNavigation: "networkidle0",
       waitForAction: 500
     }
   }
}

# Example #2: Wait for DOMContentLoaded event

{
   helpers: {
     Playwright : {
       url: "http://localhost",
       restart: false,
       waitForNavigation: "domcontentloaded",
       waitForAction: 500
     }
   }
}

# Example #3: Debug in window mode

{
   helpers: {
     Playwright : {
       url: "http://localhost",
       show: true
     }
   }
}

# Example #4: Connect to remote browser by specifying websocket endpoint (opens new window)

{
   helpers: {
     Playwright: {
       url: "http://localhost",
       chromium: {
         browserWSEndpoint: 'ws://localhost:9222/devtools/browser/c5aa6160-b5bc-4d53-bb49-6ecb36cd2e0a',
         cdpConnection: false // default is false
       }
     }
   }
}

# Example #5: Testing with Chromium extensions

official docs (opens new window)

{
 helpers: {
   Playwright: {
     url: "http://localhost",
     show: true // headless mode not supported for extensions
     chromium: {
       // Note: due to this would launch persistent context, so to avoid the error when running tests with run-workers a timestamp would be appended to the defined folder name. For instance: playwright-tmp_1692715649511
       userDataDir: '/tmp/playwright-tmp', // necessary to launch the browser in normal mode instead of incognito,
       args: [
          `--disable-extensions-except=${pathToExtension}`,
          `--load-extension=${pathToExtension}`
       ]
     }
   }
 }
}

# Example #6: Launch tests emulating iPhone 6

const { devices } = require('playwright');

{
 helpers: {
   Playwright: {
     url: "http://localhost",
     emulate: devices['iPhone 6'],
   }
 }
}

# Example #7: Launch test with a specific user locale

{
 helpers: {
  Playwright : {
    url: "http://localhost",
    locale: "fr-FR",
  }
 }
}
  • # Example #8: Launch test with a specific color scheme

{
 helpers: {
  Playwright : {
    url: "http://localhost",
    colorScheme: "dark",
  }
 }
}
  • # Example #9: Launch electron test

{
 helpers: {
    Playwright: {
      browser: 'electron',
      electron: {
        executablePath: require("electron"),
        args: [path.join('../', "main.js")],
      },
    }
  },
}

Note: When connecting to remote browser show and specific chrome options (e.g. headless or devtools) are ignored.

Grab WebElements for given locator Resumes test execution, so should be used inside an async function with await operator.

const webElements = await I.grabWebElements('#button');

# Parameters

Returns Promise (opens new window) WebElement of being used Web helper

# grabWebSocketMessages

This is Playwright's built-in alternative to using REST helper's sendGet, sendPost, etc methods.

# Parameters

Returns Promise (opens new window)<object (opens new window)> response

# mockRoute

Mocks network request using browserContext.route (opens new window) of Playwright

I.mockRoute(/(.png$)|(.jpg$)/, route => route.abort());

This method allows intercepting and mocking requests & responses. Learn more about it (opens new window)

# Parameters

# mockTraffic

Mocks traffic for URL(s). This is a powerful feature to manipulate network traffic. Can be used e.g. to stabilize your tests, speed up your tests or as a last resort to make some test scenarios even possible.

Examples:

I.mockTraffic('/api/users/1', '{ id: 1, name: 'John Doe' }');
I.mockTraffic('/api/users/*', JSON.stringify({ id: 1, name: 'John Doe' }));
I.mockTraffic([/^https://api.example.com/v1/, 'https://api.example.com/v2/**'], 'Internal Server Error', 'text/html');

# Parameters

  • urls string|Array These are the URL(s) to mock, e.g. "/fooapi/" or "['/fooapi_1/', '/barapi_2/*']". Regular expressions are also supported.
  • responseString string The string to return in fake response's body.
  • contentType Content type of fake response. If not specified default value 'application/json' is used.

# moveCursorTo

Moves cursor to element matched by locator. Extra shift can be set with offsetX and offsetY options.

I.moveCursorTo('.tooltip');
I.moveCursorTo('#submit', 5,5);

# Parameters

Returns void automatically synchronized promise through #recorder

# openNewTab

Open new tab and automatically switched to new tab

I.openNewTab();

You can pass in page options (opens new window) to emulate device on this page

// enable mobile
I.openNewTab({ isMobile: true });

# Parameters

  • options

# pressKey

Note: Shortcuts like 'Meta' + 'A' do not work on macOS (GoogleChrome/Puppeteer#1313 (opens new window)).

Presses a key in the browser (on a focused element).

Hint: For populating text field or textarea, it is recommended to use fillField.

I.pressKey('Backspace');

I.pressKey(['Control', 'Z']);

For specifying operation modifier key based on operating system it is suggested to use 'CommandOrControl'. This will press 'Command' (also known as 'Meta') on macOS machines and 'Control' on non-macOS machines.

I.pressKey(['CommandOrControl', 'Z']);

Some of the supported key names are:

  • 'AltLeft' or 'Alt'
  • 'AltRight'
  • 'ArrowDown'
  • 'ArrowLeft'
  • 'ArrowRight'
  • 'ArrowUp'
  • 'Backspace'
  • 'Clear'

# resizeWindow

Unlike other drivers Playwright changes the size of a viewport, not the window! Playwright does not control the window of a browser, so it can't adjust its real size. It also can't maximize a window.

// inside codecept.conf.js
// @codeceptjs/configure package must be installed
{ setWindowSize } = require('@codeceptjs/configure');

Resize the current window to provided width and height. First parameter can be set to maximize.

Returns void automatically synchronized promise through #recorder

# restartBrowser

// Restart browser and use a new timezone
I.restartBrowser({ timezoneId: 'America/Phoenix' });

// Restart browser, allow reading/copying of text from/into clipboard in Chrome
I.restartBrowser({ permissions: ['clipboard-read', 'clipboard-write'] });

# Parameters
