Testing in Chrome

$ browser-runner script.js

Testing in Firefox (experimental)

You can test with Firefox using the puppeteer option product.

$ browser-runner script.js --product firefox

Important: First time the execution will take longer since it has to download the firefox browser.

Process exit

browser-runner cannot know when your script finish the execution.

If you want to exit the process at some point in your script runs:

process.exit(code) // 0 success 1 error

Or throw an unhandled Error

Environment variables

Your script can use environment variables from the shell or a .env file.

// script.js

console.log(process.env.NODE_ENV) // development
console.log(process.env.SOME_VARIABLE) // foo

$ NODE_ENV=development SOME_VARIABLE=foo browser-runner scripts.js
