Synchronisation commands - SELENIUM

waitFor and Pause  Both are synchronization commands.

waitForPageToLoad(timeout)

Arguments:

• timeout – a timeout in milliseconds, after which this command will return with an error

Waits for a new page to load.

You can use this command instead of the “AndWait” suffixes, “clickAndWait”, “selectAndWait”, “typeAndWait” etc. (which are only available in the JS API).
Selenium constantly keeps track of new pages loading, and sets a “newPageLoaded” flag when it first notices a page load. Running any other Selenium command after turns the flag to false. Hence, if you want to wait for a page to load, you must wait immediately after a Selenium command that caused a page-load.
Pause:

pause(waitTime)

Arguments:

• waitTime – the amount of time to sleep (in milliseconds) Wait for the specified amount of time (in milliseconds).

Difference

If pages loads before the time it will continue to next step.
Pause:—Will pause test until the specified time

Let’s say there are 6 commands in your script and you want to pause your script at 3rd command.
Right click on command 3 and select Toggle/Break Point. Automatically you can see pause symbol in the test case pane. Your test will be paused at command 3. If you want to remove the pause repeat the same step. Pause symbol should be removed.

Set/Clear Start Point
