WPF - Unit Testing

[navalkishorsah]

When we attempt to open the WPF window as part of one of the unit tests, we receive the following error. The control used in this window is ChromiumWebBrowser. [CefSharp Version: 113.1.40]

Error: Exit code is -532462766 ([1115/161107.951:WARNING:chrome_browser_cloud_management_controller.cc(87)] Could not create policy manager as CBCM is not enabled.)

Would you kindly let us know how to solve this?

It's just a warning and generally safe to ignore in my experience. Unlikely related to any problem you are having.

For Unit testing you need to make sure you:

• Only run CefSharp in the default AppDomain (it won't run in any other due to limitations of Microsoft VC++)
• Call Cef.Initialzie and Cef.Shutdown on the SAME thread.

I'd suggest using xUnit if you aren't already as it can support disabling AppDomains which you'll need. The CefSharp.Test project as a reference.

Thank you for your response!

The NUnit Framework is being used. Despite having the necessary DLLs at the proper location, we are encountering the following exception when debugging the unit test.

System.IO.FileNotFoundException: 'Could not load file or assembly 'CefSharp, Version=113.1.40.0, Culture=neutral, PublicKeyToken=40c4b6fc221f4138' or one of its dependencies. The system cannot find the file specified.

This exception occurs at InitializeComponent() OR Cef.Initialize

Would you kindly recommend a fix for the NUnit framework?

Here are two of the key parts of the xUnit project.

• https://github.com/cefsharp/CefSharp/blob/master/CefSharp.Test/BindingRedirectAssemblyResolver.cs
• https://github.com/cefsharp/CefSharp/blob/master/CefSharp.Test/CefSharpFixture.cs

Make sure your tests are running in the default AppDomain.

System.IO.FileNotFoundException: 'Could not load file or assembly 'CefSharp, Version=113.1.40.0, Culture=neutral, PublicKeyToken=40c4b6fc221f4138' or one of its dependencies. The system cannot find the file specified.

You might need an assembly resolver as per example linked above.
