I understand there is a need for a more complete answer than what @james-fera posted. I have learned from his answer and made a github project consisting of a test project and API project. The code should be self-explanatory and not hard to understand.

https://github.com/emedbo/identityserver-test-template

The IdentityServerSetup.cs class https://github.com/emedbo/identityserver-test-template/blob/master/tests/API.Tests/Config/IdentityServerSetup.cs can be abstracted away e.g. NuGetted away, leaving the base class IntegrationTestBase.cs

The essences is that can make the test IdentityServer work just like a normal IdentityServer, with users, clients, scopes, passwords etc. I have made the DELETE method [Authorize(Role="admin)] to prove this.

Instead of posting code here, I recommend read @james-fera's post to get the basics then pull my project and run tests.

IdentityServer is such a great tool, and with the ability to use the TestServer framework it gets even better.
