WatiN UnauthorizedAccessException errors

问题

I am getting UnauthorizedAccessException errros when running any tests using NUnit and WatiN:

Test Test.IndexTests.Can_Do' failed: WatiN.Core.Exceptions.ElementNotFoundException : Could not find INPUT (hidden) or INPUT (password) or INPUT (text) or INPUT (textarea) or TEXTAREA element tag matching criteria: Attribute 'name' equals 'q' at http://www.google.com/ (inner exception: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)))

I can't seem to find anything via google and was wondering if anyone has had a similar problem?

Try my answer to other question:

Try turning off IE's protected mode or add your site to trusted zone.

WatiN permissions problem when eval javascript code

回答2:

It can happen when the HTML is not entirely loaded You can add Sleep or add the wait for complete command

ie.WaitForComlete();

The best way is to catch the specific exception and try it again:

     try
     {
         //your code
     }
     catch (UnauthorizedAccessException)
     {

     }

The solution for me was to uninstall the Trusteer Rapport browser security software that my bank offers. I had forgotten it was even installed.

回答4:

I had the same problem at random positions in the test. I was already running in the trusted zone.

Adding a

System.Threading.Thread.Sleep(200);

at each problem location "solved" the problem or at least its symptoms for me. At least I do not get the error anymore and am able to run the tests.

It seems to be a race condition somewhere.
