Exception while using Sitecore.Fakedb

Question

I am trying to setup test framework for my Sitecore solution. In that we are using fakedb to create the sitecore context. We are getting below exception on a static function.

System.TypeInitializationException
  HResult=0x80131534
  Message=The type initializer for 'Sitecore.SecurityModel.License.LicenseManager' threw an exception.
  Source=Sitecore.Kernel

  This exception was originally thrown at this call stack:

Answer 1

You need to have a reference to Sitecore.nexus.dll

Method 1 : The Sitecore.Nexus assembly is in the Bin folder of your Sitecore website. Add a reference to this assembly from your test project.

Method 2 : Or you can use NuGet package.

In Visual Studio: Tools -> Options

In Options window find 'Nuget Package Manager' -> 'Package Sources'

Then click the green plus and fill Name and Source text fields.

Name one - whatever you want.

Source text field fill with https://sitecore.myget.org/F/sc-packages/api/v3/index.json

After that go to Tools->Nuget Package Manager->Manage Nuget Packages for Solution... In 'Package source' dropdown in right-top corner choose just add source. In my case it is 'Sitecore'. In search field type 'Sitecore.Nexus.Noreferences' or Sitecore.Nexus with no dependency:

Choose a project you want to install package and click Install button.

Answer 2

In my case, I have looked for a similar issue before and found that it was because the Sitecore.Nexus DLL was blocked.

So to resolve this, I removed that reference to Sitecore.Nexus from the project, unblocked the DLL, re-added the reference and it worked.

See below link to check for details on unblocking DLLs

Finally, I would suggest you check that is there any config missing in your solution. Check if you have forgotten to add anything related.

Thanks
