By simply changing a few lines of code in your existing Selenium tests, you can start running them on Device Farm’s fully managed browser grid. With Device Farm, you only pay for the time your tests are executing on the browsers and can scale to fifty concurrent Selenium sessions without having to incur any additional costs. For every browser instance your test is executed on, Device Farm generates videos, action logs, console logs, and WebDriver logs so you can quickly identify and fix issues with your web applications.
