difference b/w implicitly Wait and Explicit wait

    Please tell me the difference b/w implicitly Wait () and Explicit wait.

Implicit Wait sets internally a timeout that will be used for all consecutive Web Element searches. It will try lookup the element again and again for the specified amount of time before throwing a NoSuchElementException if the element could not have been found. It does only this and can't be forced into anything else - it waits for elements to show up.

Explicit Wait or just Wait is a one-timer used by you for a particular search. It is more extendible in the means that you can set it up to wait for any condition you might like. Usually, you can use some of the prebuilt Expected Conditions to wait for elements to become clickable, visible, invisible, etc., or just write your own condition that suits your needs.

difference between thread. Sleep () and selenium. Set Speed ("2000")

       What is the difference between thread. Sleep () and selenium. Set Speed ("2000")?

If the application is taking time to load the page then we use selenium.waitforpageload(" "). This command is doesn’t wait upto the given time whenever the page load is completed.

If the application is taking time to refresh the page, then we use Thread. Sleep ( ).it is a standard wait it simply wait to the given time.

selenium.setSpeed

 1. Takes a single argument in string format

 Ex: selenium.setSpeed("2000") - will wait for 2 seconds

 2. Runs each command in after setSpeed delay by the number of milliseconds mentioned in set Speed.

 thread.sleep

 1. Takes a single argument in integer format

 ex: thread. Sleep(2000) - will wait for 2 seconds

 2. Waits for only once at the command given at sleep.
