@bahmutov/cypress-extends

Cypress plugin that adds "extends" support to the configuration file. This allows the config files to remain DRY and avoid duplicating data, but still have multiple files for different scenarios. See details in Extending the Cypress Config File blog post.

Use

npm i -D @bahmutov/cypress-extends
# or
yarn add -D @bahmutov/cypress-extends

Add this module to your cypress/plugins/index.js file

module.exports = (on, config) => {
  // `on` is used to hook into various events Cypress emits
  // `config` is the resolved Cypress config
  return require('@bahmutov/cypress-extends')(config.configFile)
}

Start using extends syntax in your Cypress configuration file

// cypress.json
{
  "extends": "./base.json"
}
// base.json
{
  "fixturesFolder": false,
  "supportFile": false,
  "$schema": "https://on.cypress.io/cypress.schema.json"
}

Tip: the $schema property in JSON files lets modern IDE show intelligent code completion for Cypress config values.

Debugging

Run Cypress with environment variable

DEBUG=@bahmutov/cypress-extends npx cypress run
# or
DEBUG=@bahmutov/cypress-extends npx cypress open
