.NET Core - Using ClaimsIdentity in your unit tests

To be able to test my application I had to create a ‘dummy’ ClaimsPrincipal and ClaimsIdentity:

	var claimsIdentity = new ClaimsIdentity();
	claimsIdentity.AddClaim(new Claim("http://schemas.example.be/iam/claims/userid", "123"));
	claimsIdentity.AddClaim(new Claim("http://schemas.example.be/iam/claims/username", "test"));
	var claimsPrincipal = new ClaimsPrincipal(claimsIdentity);

However when I tried to run my test, the test failed because the ClaimsIdentity returned ‘false’ for the IsAuthenticated check.

To create an authenticated ‘dummy’ identity I had to pass on an extra ‘authenticationType’ parameter to the constructor:

	var claimsIdentity = new ClaimsIdentity(authenticationType:"test");
	claimsIdentity.AddClaim(new Claim("http://schemas.example.be/iam/claims/userid", "123"));
	claimsIdentity.AddClaim(new Claim("http://schemas.example.be/iam/claims/username", "test"));
	var claimsPrincipal = new ClaimsPrincipal(claimsIdentity);

The exact value that you specify doesn't matter.
