parallel testing vs cross browser testing code example

Example 1: difference between parallel testing and cross browser testing

Cross Browser Testing: When we do crossbrowser testing we
execute multiple test scripts on different browsers one by
one. When one test executed/completed another browser
would be invoked on the current browser.

--Parallel Execution: In parallel testing multiple browsers are
invoked simultaneously and all the test scripts are executed
parallelly.
