The `TestAuthHandler` is called to authenticate a user when the authentication scheme is set to `TestScheme` where `AddAuthentication` is registered for `ConfigureTestServices`. It's important for the `TestScheme` scheme to match the scheme your app expects. Otherwise, authentication won't work.
The `TestAuthHandler` is called to authenticate a user when the authentication scheme is set to `TestScheme` where `AddAuthentication` is registered for `ConfigureTestServices`. `DefaultAuthenticateScheme` and `DefaultChallengeScheme` are explicitly set to `TestScheme` to ensure the test handler overrides any authentication configuration set by the app. It's important for the `TestScheme` scheme to match the scheme your app expects. Otherwise, authentication won't work.
