Horizontal scaling – cross-browser testing

There are three ways in which you can do cross-browser testing for your projects:

• Using the built-in functionality via the wdio config file
• Using LambdaTest online to automate the browser testing grid
• Using Selenium Standalone server to locally build the testing grid

Although we will discuss all three ways, in this book, our examples will be completed using the built-in functionality provided by the wdio config file.
