Hello Nathan,

I recreated your environment on a VM running Win7, VS2010, Framework 2011.1.624, and Chrome 12.0.742.122. Unfortunately I could not reproduce your issue as the browser launched and the test executed successfully.

Please confirm that the WebUI browser automation extension is enabled. Is it the only extension? If not, please disable or uninstall the other extensions. We commonly see other browser extensions/add-ons interfere with our test automation.

Hi - thanks for investigating. Unfortunately, I'm still running into the issue and it's an adoption blocker for my team. Here's a little more information (which will hopefully help identify the problem).

The WebUI extension is the only extension installed (and it is enabled). I'm running the test using code only. I get the same result running a test that I've written or one that is included in the framework's sample solution (if I change the call to LaunchNewBrowser(...) to specify Chrome). Chrome does actually launch and ActiveBrowser.Navigate(...) executes without throwing an exception, but Chrome does not actually navigate to the desired page; it just displays "Preparing browser for automation...".

In the following code snippet (from the framework's sample .sln), the test will run until Find.ById(...) is called, at which point an exception will be thrown because the page containing the desired element was never navigated to. This works fine using FF and IE (but not Chrome).

[

TestMethod]

[

Description("Clicking an element on the page.")]

public void ClickAnElement()

{

// Launch an instance of the browser

//Manager.LaunchNewBrowser();

Manager.LaunchNewBrowser(ArtOfTest.WebAii.Core.

BrowserType.Chrome, true);

// Some test cases may require that all cookies be cleared ahead of time.

// WebAii does not care but depending on your environment and your specific

// test case you may care.

ActiveBrowser.ClearCache(ArtOfTest.WebAii.Core.

BrowserCacheType.Cookies);

// Navigate to the test page

ActiveBrowser.NavigateTo(

Path.Combine(TestContext.TestDeploymentDir, TESTPAGE));

// Find the elements on the page using the Find.BYxxx methods.

Element toggleOn = Find.ById("btn1");

I've also tried restarting by machine after installing the framework and setting Chrome to run as administrator, but still no luck.

Any help is appreciated!

Do the following tasks:

--Repair and Clean Registry Errors
--Repair Flash: You may also need to repair your Flash player in order to stop Google Chrome from hanging. You can repair Flash in this way
--Run Scans for Malwares: Sometimes due to intrusion of malwares in the system, Google Chrome hangs or crashes. To end freezing and hanging problems with your browser, running scan with an antimalware software is quite helpful.

If your browser is hanging or crashing all the time then updating the sound drivers may also help.

I also got some help from this article Google Chrome Hangs
Hope it fix your problem.
