'The pipe endpoint 'net.pipe://localhost/Telerik/TestingFramework.Hosts.Manager' could not be found on your local machine' running with Chrome

[Steve]

Occasionally when testing with Chrome as the browse, I get this exception when it tries to launch the browser:

There was no endpoint listening at net.pipe://localhost/Telerik/TestingFramework.Hosts.Manager that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

Here's the inner exception:

The pipe endpoint 'net.pipe://localhost/Telerik/TestingFramework.Hosts.Manager' could not be found on your local machine.

Rerunning the test alleviates the problem, so it's not an issue of the manager not being found...

Hi Steve,

We're not aware of any problems running tests in Chrome. I have a few questions:

1) What version of Windows are you running?
2) What version of Chrome are you using?
2) What do you use for Anti-virus? Some include a proxy to monitor Internet communications.

Chrome Version 37.0.2062.124 m
Windows 7 SP1 (x64)
Symantec Endpoint Protection on some machines, nothing on others, and I get it to reproduce occasionally on various machines here.  Always seems to be the first run of the day, or after a reboot, if that helps.  Technically, what is happening behind the scenes with regards to using pipes and other communications when running a test?  Maybe knowing that will help me chase this down further.

Hello Steve,

I've tried a few times but unable to reproduce any problems on my machine. It may be I'm not following the exact same steps as you. A couple more questions:

1) What you are using as your test runner? Visual Studio (which version)? Nunit? XUnit? MBUnit?
2) Can you send me a complete test project I can execute here that shows the problem? It needs to run against a publicly accessible URL.

Like I said before, it's very random, and seems to happen after a reboot, but only one time.  Then, I'm usually good all day.  But, to answer your questions:

Visual Studio 2012 and 2013 instances both do this.
The only thing you need to do to reproduce it is call LaunchNewBrowser - that's where it fails every time when it fails. 

This didn't happen with a release of Webaii maybe 2 revisions old, but that's relying on my memory.  If you can't reproduce it, it's no big deal, I'll continue to live with it, but I would still like to know more of the technical details of what exactly WebAii is doing when it tries to launch the browser with the UseHttpProxy set to True.  It seems like the manager must adjust the proxy settings on the machine to point to itself, and then is resets those values when the test is finished.

Sometimes, I'll get a windows error "The Telerik Manager something something has stopped responding - close the program check for solutions, blablabla" and then I go look at the proxy settings in Internet Properties, and the "Use Proxy" checkbox is checked, with no value for the proxy server name/address/port... Next time I get a crash in the manager, I'll gather up the error messages and put them here - maybe that will help...

Hi Steve,

I'm setting up a different environment to try and repro this. I'll let you know my results.

Hi Steve,

After multiple attempts and multiple reboots I've not had a single occurrence of "The pipe endpoint 'net.pipe://localhost/Telerik/TestingFramework.Hosts.Manager' could not be found on your local machine' running with Chrome".

I am running into this problem consistently.  I do not see this issue when running locally, and the same automation will run fine in Internet Explorer 11.  It fails when we attempt to run any test in Chrome on a VM through Microsoft Test Manager.  The VM has the most up to date Chrome and Telerik Automation Framework.  The VM is Windows Server 2008 R2 Standard Service Pack 1 with Visual Studio 2013 installed.  See the attached file for a screen shot of what appears: Chrome opens a window, then throws a Telerik.TestingFramework.Hosts.Manager error.  Below is the stack trace and error message

There was an error during test setup. System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/Telerik/TestingFramework.Hosts.Manager that could accept the message. This is often caused by an incorrect address or SOAP action.
