TestComplete supports testing applications created with Silverlight 4 or 5.

TestComplete can test only those Silverlight applications that were compiled and packed to an application package (the .xap file). Silverlight applications loaded by wrapper web pages directly from XAML source code files (.xaml) without using .xap package files are not supported.

The tested Silverlight application must run in one of the following Internet browsers:

• Internet Explorer ver. 11, including Silverlight 5 applications running in 64-bit versions of Internet Explorer.

• Any web browser based on the Microsoft WebBrowser control (but not the Edge-based WebBrowser control).

Clear the browser cache and set the page's zoom ratio to 100% before testing. See the Preparing a Web Browser for Testing Silverlight Applications topic for more information.

Silverlight in-browser applications running under Mozilla Firefox and Silverlight out-of-browser applications can be tested only via the UI Automation technology which provides less access to the application internals.

You must have Silverlight ver. 4.0.50826.0 or later installed on the TestComplete computer. You can download the latest Silverlight version from here:

When your Silverlight application communicates through the secure hypertext transfer protocol (HTTPS), TestComplete cannot automatically gain in-depth access to the application. In order to test such an application, you should manually process it with the tcAgPatcher utility as described in the Preparing In-Browser Silverlight Applications for Testing topic.

• The tested Silverlight application must be compiled and packed to a package file (.xap) from which a wrapper web page will load the application. TestComplete does not support Silverlight applications that are loaded by wrapper web pages directly from XAML files (.xaml) containing the applications’ source code. Due to some specifics of such Silverlight applications, TestComplete cannot recognize their internal objects and make them testable.

  The following example demonstrates embedding of supported and unsupported Silverlight applications into a wrapper web page via an object HTML element:

  HTML

  Copy Code

  HTML

  <!-- Embedding a Silverlight application from a .xap file (supported) -->
  <div id="silverlightControlHost">
      <object width="640" height="480" data="data:application/x-silverlight-2," type="application/x-silverlight-2" >
          <param name="source" value="MySilverlightApp.xap"/>
          <param name="minRuntimeVersion" value="4.0.50826.0" />
          <a href="http://go.microsoft.com/fwlink/?LinkID=124807" style="text-decoration: none;">
              <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
          </a>
      </object>
  </div>
  
  <!-- Embedding a Silverlight application from a .xaml file (unsupported) -->
  <div id="silverlightControlHost">
      <object width="640" height="480" data="data:application/x-silverlight-2," type="application/x-silverlight-2" >
          <param name="source" value="MySilverlightApp.xaml"/>
          <param name="minRuntimeVersion" value="4.0.50826.0" />
          <a href="http://go.microsoft.com/fwlink/?LinkID=124807" style="text-decoration: none;">
              <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
          </a>
      </object>
  </div>

• Generally, TestComplete automatically treats tested Silverlight applications as Open Applications. That is, TestComplete provides access to the applications’ internal objects, their methods, properties and fields without special preparations.

  However, there are cases when the automatic Silverlight application patching mechanism is not supported and you must prepare your application manually.

  To learn which applications are patched automatically and which are not, and how to patch applications manually, see Preparing In-Browser Silverlight Applications for Testing.

• TestComplete is unable to recognize objects, methods and properties of a Silverlight application automatically if the application is running on a server that requires Negotiate, NTLM or some other authentication.

  In order for TestComplete to be able to access internal objects, methods and properties of this Silverlight application, prepare the application for testing with the tcAgPatcher utility. See Preparing In-Browser Silverlight Applications for Testing for complete information.

Once your Silverlight application uses cross-domain communication, you need to put additional efforts to test it with TestComplete. See detailed instructions in the “Making Cross-Domain Silverlight Applications Testable with TestComplete” section of the Preparing In-Browser Silverlight Applications for Testing topic.

Core Silverlight Plugins

TestComplete support for testing Silverlight applications is provided by the following plugins:

• Silverlight Application Support
• Open Applications
• Web Testing

These plugins are installed and enabled automatically. Therefore, you can test most Silverlight applications right out-of-box, without any additional configuration.

You can check to see if these plugins are active by selecting File > Install Extensions from the TestComplete main menu. If one of these plugins is not available, you need to run the TestComplete installation in the Repair mode.

To use the plugins, you must have a license for TestComplete Web module.

The TestComplete Web module also includes pre-installed plugins for automated testing of Silverlight controls. These plugins provide test objects, methods and properties for automating various operations on Silverlight controls, getting their contents, state and so on.

• Supported Microsoft Controls

• Supported Telerik Controls

Just like core Silverlight support plugins, these plugins are also installed and enabled automatically.

You can verify that these plugins are active using the File | Install Extensions dialog. To re-install the plugins, run the TestComplete installation in the Repair mode.
