How to mock Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet? #890
Closed
Description
Background
I have a project which is testing views served from a class library (Microsoft.NET.Sdk.Razor).
In order to do this, the test project itself is of MsBuild SDK type Microsoft.NET.Sdk.Web.
The views in the class library use the injected Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet.
When I run a unit test where an HttpClient tries to render the view, I get the following error:
[xUnit.net 00:00:01.58] xxx.Frontend.Test.PageTests.Index_matches_snapshot [FAIL]
[xUnit.net 00:00:01.58] System.InvalidOperationException : No service for type 'Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet' has been registered.

Question
How can I mock Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet?
I tried adding singleton via my test's StaptUp.cs - ConfigureServices(IServiceCollection ...):
services.AddSingleton(JavaScriptSnippet, JavaScriptSnippet); but this fails because JavaScriptSnippet is a type.
The JavaScriptSnippet metadata doesn't show any interface it's using so I'm not able to register my own mock.
Repro Steps
- Create a class library of type
Microsoft.NET.Sdk.Razorand add views which useMicrosoft.ApplicationInsights.AspNetCore.JavaScriptSnippet. - Create an xUnit test project of type
Microsoft.NET.Sdk.Weband add the class library as a project reference. - Run the test.
Actual Behavior
The above callstack occurs.
Expected Behavior
The test should complete without the exception.
