cloud-grid-e2e

Overview

A cloud grid is a hosted farm of real devices + browsers exposed through a W3C-compliant WebDriver endpoint. Point any WebDriver client (Selenium, WebdriverIO, Nightwatch) at the vendor's hub URL and the suite runs on combinations the local machine cannot host: real Safari on iOS, legacy browser versions, niche Android devices.

The three major vendors are isomorphic - the same suite moves between them by swapping four things:

Concern	BrowserStack	Sauce Labs	LambdaTest
Auth env vars	`BROWSERSTACK_USERNAME` + `BROWSERSTACK_ACCESS_KEY`	`SAUCE_USERNAME` + `SAUCE_ACCESS_KEY`	`LT_USERNAME` + `LT_ACCESS_KEY`
Hub URL	`https://hub-cloud.browserstack.com/wd/hub`	regional, e.g. `https://ondemand.us-west-1.saucelabs.com:443/wd/hub`	`https://hub.lambdatest.com/wd/hub`
Vendor options dict	`bstack:options`	`sauce:options`	`LT:Options`
