Get Started With Selenium Testing

Run your Selenium tests on TestMu AI's cloud grid of 10,000+ browser/device combinations. Point your tests at the hub URL, add capabilities, and get parallel execution, video recordings, logs, and screenshots for every session - no infrastructure to maintain.

Before You Begin

You need a TestMu AI account. Sign up free if you don't have one.
Visit the TestMu AI Dashboard and navigate to the left sidebar and select Credentials. Your Username and Access Key will be visible there, along with options to copy them for use.
Set them as environment variables:

macOS / Linux
Windows

export LT_USERNAME="YOUR_USERNAME"
export LT_ACCESS_KEY="YOUR_ACCESS_KEY"

set LT_USERNAME="YOUR_USERNAME"
set LT_ACCESS_KEY="YOUR_ACCESS_KEY"

Your tests connect to the grid at:

https://{username}:{accessKey}@hub.lambdatest.com/wd/hub
