//   a. using the name of the interface i.e. "Foo::Bar"
//   b. using the type of the interface i.e. <Foo::Bar>
// multiplied with 2 ways to get the service reference
//   a. using the name of the interface
//   b. using the type of the interface
// NOTE: We do have tests for this in different places,
// but this test consolidates all these modes together.
