Selenium Grid code for test in different Browser and OS

Selenium Grid code for test in different Browser and OS

Selenium Grid is a part of the Selenium Suite that specializes on running multiple tests across different browsers, operating systems, and machines in parallel.

Selenium Grid has 2 versions - the older Grid 1 and the newer Grid 2. We will only focus on Grid 2 because Grid 1 is gradually being deprecated by the Selenium Team. 

When to Use Selenium Grid?

You should use Selenium Grid when you want to do either one or both of following :

• Run your tests against different browsers, operating systems, and machines all at the same time.This will ensure that the application you are testing is fully compatible with a wide range of browser-OS combinations.
• Save time in execution of your test suites. If you set up Selenium Grid to run, say, 4 tests at a time, then you would be able to finish the whole suite around 4 times faster.

Dynamic Alert handling code:-

 if(wait.until(ExpectedConditions.alertIsPresent())==null){
         
     }else{
         action.alertAccept();
     }
