Custom browsers

Cypress v3.7.0+ allows the project to customize the list of browsers. In this example, cypress/plugins/index.js filters the list of all browsers detected on the user's machine and only returns the bundled Electron browser. Or you could do the opposite and only allow the project to use Chrome browsers

// cypress/plugins/index.js
module.exports = (on, config) => {
  return {
    browsers: config.browsers.filter((browser) => browser.family === 'chrome'),
  }
}

Custom browser

Plugins file can also adjust or overwrite the list of browsers. For example cypress/plugins/brave.js file finds the Brave Browser and returns only that browser.

npx cypress open --config pluginsFile=cypress/plugins/brave.js

If you want to use Brave browser during non-interactive run, pass its name

npx cypress run --config pluginsFile=cypress/plugins/brave.js --browser brave

Tip: if you are passing lots of --config options, set them in a new configuration file, like cypress-brave.json and use

npx cypress run --config-file cypress-brave.json
