Is it possible to automate Silverlight in windowless mode?

Question

Does anybody have an application under test (AUT) that uses a mixture of HTML and Silverlight controls, which they have successfully automated?

My AUT web app has screens with a mixture of HTML and Silverlight, and this requires silverlight to run in Windowless mode.

But, this apparently makes the Silverlight elements opaque to automation (according to Ranorex). I've tried a few different automation tools now, without success (they are unable to distinguish elements within the Silverlight area). Before I waste my time trying and failing with every tool there is, does anybody have any experience of this at all?

Answer 1

TestComplete should be able to access internal Silverlight properties, even in Windowless mode.
At the same time it allows to perform functional web testing [1, 2].

And another possible solution...

You can achieve this when performing SilverLight Isolated API / Unit Testing.
Here's an example.

Unit tests usually run against SilverLight's Windowless mode. So you can look for Silverlight unit-testing tools and use them in collaboration with web testing tools, e.g. with Selenium WebDriver.
