Configuration hook helps you update CodeceptJS configuration at ease.

Those hooks are expected to simplify configuration for common use cases.

Requires CodeceptJS >= 2.3.3

npm i @codeceptjs/configure --save

Better to see once.

Toggle headless mode for Puppeteer, WebDriver, TestCafe and Playwright on condition.

Usage:

// in codecept.conf.js
const { setHeadlessWhen } = require('@codeceptjs/configure');

// enable headless when env var HEADLESS exists
// Use it like:
//
// export HEADLESS=true && npx codeceptjs run
setHeadlessWhen(process.env.HEADLESS); 

exports.config = {
  helpers: {
    // standard config goes here
    WebDriver: {} 
    // or Puppeteer
    // or TestCafe
  }
}

• For Puppeteer, TestCafe, Playwright: it enables show: true.
• For WebDriver with Chrome or Firefox browser: it adds --headless option to chrome/firefox options inside desiredCapabilities.

Opposite to setHeadlessWhen. Forces window mode for running tests.

// in codecept.conf.js
const { setHeadlessWhen } = require('@codeceptjs/configure');

// enable window mode when env var DEV exists
// Use it like:
//
// export DEV=true && npx codeceptjs run
setHeadedWhen(process.env.DEV); 

Enables CodeceptJS plugins which are recommened for common usage. The list of plugins can be updated from version to version so this hook ensures that all of them are loaded and you won't need to update them in a config:

// in codecept.conf.js
const { setCommonPlugins } = require('@codeceptjs/configure');

setCommonPlugins();

These plugins will be loaded:

• tryTo (enabled globally)
• retryFailedStep (enabled globally)
• retryTo (enabled globally)
• eachElement (enabled globally)
• pauseOnFail (disabled, should be turned on when needed)
• screenshotOnFail (enable globally)

Shares cookies between browser and REST/GraphQL helpers.

This hooks sets onRequest function for REST, GraphQL, ApiDataFactory, GraphQLDataFactory. This function obtains cookies from an active session in WebDriver or Puppeteer helpers.

// in codecept.conf.js
const { setSharedCookies } = require('@codeceptjs/configure');

// share cookies between browser helpers and REST/GraphQL
setSharedCookies();

exports.config = {
  helpers: {
    WebDriver: {
      // standard config goes here      
    },
    // or Puppeteer
    // or TestCafe,
    REST: {
      // standard config goes here      
      // onRequest: <= will be set by hook
    },
    ApiDataFactory: {
      // standard config goes here
      // onRequest: <= will be set by hook
    }
  }
}

Changes browser in config for Playwright, Puppeteer, WebDriver & TestCafe:

const { setBrowser } = require('@codeceptjs/configure');

setBrowser(process.env.BROWSER);

Universal way to set a browser window size. For Puppeteer this launches Chrome browser with a specified width and height dimensions without changing viewport size.

Usage: setWindowSize(width, height).

// in codecept.conf.js
const { setWindowSize } = require('@codeceptjs/configure');

setWindowSize(1600, 1200);

exports.config = {
  helpers: {
    Puppeteer: {}
  }
}

Changes url in config for Playwright, Puppeteer, WebDriver & TestCafe:

const { setTestHost } = require('@codeceptjs/configure');

setTestHost(process.env.TEST_HOST);

Please send your config hooks!

If you feel that codecept.conf.js becomes too complicated, and you know how to make it simpler, send a pull request with a config hook to solve your case.

Good ideas for config hooks:

• Setting the same window size for all browser helpers.
• Configuring run-multiple
• Changing browser in WebDriver or Protractor depending on environment variable.

To create a custom hook follow this rules.

1. Create a file starting with prefix use in hooks directory.
2. Create a js module that exports a function.
3. Require config object from codeceptjs package.
4. Use config.addHook((config) => {}) to set a hook for configuration
5. Add a test to index.test.js
6. Run npm run test

See current hooks as examples.
