timeout Exception even when element is already clicked

I am trying to click one button Sign In but even after button is clicked I am getting timeout exception.

I have verified the code and verified that I am using right locator.

Just want the last testcase to pass

You don't need the sendEnter: true argument with any of the SendKeys actions. When you pass sendEnter: true , the action will "press" the enter key after sending the keys to the textbox element. So basically, in the test you showed, the first action will input the username and then press enter, thus trying to log in without a password, which will of course fail.

The other problem is that you are using the ActionsPause keyword incorrectly (more info here). If you want to introduce a delay in your test, you can use the $delay() API, but you very rarely need to do this with OpenTest, since synchronization is built-in, meaning all test actions that perform some work on a UI element know how to wait for that element to be available before doing the work.
