It appears that the testing framework is automating a browser that is installed on the system. For example, if I try to launch a Chrome browser, but Chrome is not installed, I get an error.

Is there an in-memory browser of any kind? I don't care if it's IE, Chrome, FireFox, or something else. I don't want to rely on a "properly" configured browser installed on the machine in order for things to work. I am also concerned about cookie sharing among concurrent browser windows (the default for IE 8 & 9).

I am aware that these issues can be addressed using specific browser configurations and registry hacks, but again, I don't really want to have to rely on browser configuration settings for things to work properly.

I'm looking for something akin to what HtmlUnit provides for the Java community, but I absolutely love the Test Studio interface for creating tests.

Thanks!
Scott

Hi,

Normally Test Studio tests cannot support this. However you posted in the free Telerik Testing Framework forum, and as a coded unit test, you have the option of trying the Asp.Net In-Process Host Server

Kind regards,

Thanks for the quick reply. However, we definitely require javascript support.

"tests that require heavy client javascript execution might not be suited for this browser since there is no javascript engine running."

Thanks anyway.

Hi,

You are correct, the ASP.NET host server does not include a JavaScript engine. The only way I know of getting JavaScript support is to execute tests in a real browser. i am sorry but I see no other possible solution for you.

For anyone else reading this, there is a port of HtmlUnit to C# (http://blog.stevensanderson.com/2010/03/30/using-htmlunit-on-net-for-headless-browser-automation/) but I found it a bit unwieldy.

The JS engines used by Chrome and Firefox (V8 and SpiderMonkey) are open source, but I don't see that anyone has taken the time to integrate them into a headless browser for .Net. I guess there just isn't enough demand at this point.

Hi Vitaliy,

We are not aware of any changes in the ASP.NET host server. As far as we know it still does not include a JavaScript engine.

I'm not sure I understand this inquiry "And it turns out that it is impossible to test SilverlightApplication it uses JS to run silverlight?". How would you run Silverlight from JavaScript? To the best of my knowledge it is not possible to launch/activate a Silverlight application using JavaScript.

I see methods where Silverlight can call a JavaScript function and maybe vice versa... but launching a Silverlight application using JavaScript? I don't see how that's even possible. As far as I know the Silverlight application must be embedded within the hosting HTML for it to load and run.

Regards,
Cody

Hi, thanks for your reply.
"How would you run Silverlight from JavaScript?" - Let's do an experiment, the browser is disabled support JS and try to load the Silverlight application, sample http://demos.telerik.com/silverlight/. And the app will not work, it can be clearly seen in the browser Chrome, FF, IE.

... A Silverlight project contains the Silverlight.js and CreateSilverlight.js files which initializes the Silverlight plug-in for use in HTML pages, a XAML file for the UI, and code-behind files for the application code. ...
https://en.wikipedia.org/wiki/Microsoft_Silverlight

Based from this, cannot run SilverlightApplication without JS.

Hello Vitaliy,

The information contained on WikiPedia regarding these Silverlight.js and CreateSilverlight.js files appears to be incorrect, or at best outdated. Reference the 3 attached screen shots. There is no Silverlight.js or CreateSilverlight.js file to be found anywhere.

I don't think disabling JavaScript in the browser demonstrates much as the browser probably disables the Silverlight runtime engine at the same time.

Now putting the above aside, what automation challenge are you trying to solve? Maybe there's a different approach we can take.

Cody
