How to invoke AddTestAuthorization() when writing Tests in Razor Syntax?

[roysurles]

Trying out Razor Syntax Tests with a Blazor component that is Authorized via Role. 'Fixture' is passed to the 'Setup' method and Services can be added to fixture.Services, but i dont see anyway to AddTestAuthorization. In the Setup method, tried:
using var ctx = new TestContext();
var authContext = ctx.AddTestAuthorization();
authContext.SetAuthorized("[email protected]", AuthorizationState.Authorized);
authContext.SetRoles("MyRole");

But still get the following exception...Bunit.TestDoubles.MissingFakeAuthorizationException

Keep getting exception: Bunit.TestDoubles.MissingFakeAuthorizationException : This test requires AuthenticationStateProvider to be supplied, because the component under test uses authentication/authorization during the test. You can fix this by calling TestContext.Services.AddAuthorization with appropriate values. More information can be found in the documentation.

Thanks

Hi @roysurles

Thanks for reporting this. You are not doing anything wrong, its a small mistake in the extension method that registers the fake auth in BETA-11.

Here is a workaround for now:

<Fixture Test="CanAddFakeAuthToContextx" Description="Fake Auth can be added to Fixture">
	<ComponentUnderTest>
		<SimpleAuthView />
	</ComponentUnderTest>

	@code
	{
		void CanAddFakeAuthToContextx(Fixture fixture)
		{
			fixture.RenderTree.TryAdd<Microsoft.AspNetCore.Components.Authorization.CascadingAuthenticationState>();
			var authCtx = new TestAuthorizationContext();
			authCtx.SetNotAuthorized();
			authCtx.RegisterAuthorizationServices(fixture.Services);
			authCtx.SetAuthorized("TestUser", AuthorizationState.Authorized);

			var cut = fixture.GetComponentUnderTest<SimpleAuthView>();

			cut.MarkupMatches("Authorized!");
		}
	}
</Fixture>

And this will work in the next release (you can try the nightly if you want this now):

<Fixture Test="CanAddFakeAuthToContext" Description="Fake Auth can be added to Fixture">
	<ComponentUnderTest>
		<SimpleAuthView />
	</ComponentUnderTest>

	@code
	{
		void CanAddFakeAuthToContext(Fixture fixture)
		{
			var authContext = fixture.AddTestAuthorization();
			authContext.SetAuthorized("TestUser", AuthorizationState.Authorized);

			var cut = fixture.GetComponentUnderTest<SimpleAuthView>();

			cut.MarkupMatches("Authorized!");
		}
	}
</Fixture>

Thanks for the quick response and work around... this works great! We will revisit this on the next version and change to the simplified syntax... thanks
