Thread.Sleep() and Selenium.setSpeed()

Thread.Sleep() - causes the current thread to suspend execution for a specified period. This is an efficient means of making processor time available to the other threads of an application or other applications that might be running on a computer system. 

Note that if there is another thread defined then it can catch InterruptedException.

Example:

Thread.sleep(3000); //3 seconds

Opeartion 1

Thread.sleep(3000);

Opeartion 2

Thread.sleep(3000);

Opeartion 3

Selenium.setSpeed()- used to set execution speed in milliseconds. Will apply a delay before Selenium operation takes place. It is done only once.

Example:

Selenium.setSpeed("3000");

Opeartion 1        // Selenium operation

Opeartion 2

Opeartion 3
