Please HELP!!! The test script was ready for execution. I run this script for a several times today and I didn't receive any errors. But the last 5 times when I was trying to execute it I got this error:
------------------------------------------------------------
'2/17/2011 3:33:56 PM' - Starting execution....
'2/17/2011 3:34:49 PM' - Failure detected during execution. Details:
------------------------------------------------------------
'2/17/2011 3:34:49 PM' - System.NullReferenceException: Object reference not set to an instance of an object.

------------------------------------------------------------
'2/17/2011 3:34:49 PM' - Test completed!
Note1: the status of the test is "Fail - 0 passed out of total 0 executed" but I could see the progress of this test during execution and all steps were passed.
Note2: I get this error only when I add "Close IE window" step in the end of the test

Hello nastia,
Cody
That is a strange one. It looks like something is interfering with the test starting up IE.
Does IE launch when you try to start the test?
A couple of fairly obvious things to try:
- Completely close and restart WebUI Test Studio
- Close all instances of IE
- Restart the computer
Let me know if you still have trouble after trying the above suggestions.
