// Creates Connector instances which route BindInterface requests directly to
// manually registered Service implementations. Useful for testing production
// code which is parameterized over a Connector, while bypassing all the
// Service Manager machinery. Typical usage should look something like:
//
//     TEST(MyTest, Foo) {
//       base::test::TaskEnvironment task_environment;
//       TestConnectorFactory connector_factory;
//       my_service::MyServiceImpl service(connector_factory.RegisterInstance(
//           my_service::mojom::kServiceName));
//
//       RunSomeClientCode(connector_factory.GetDefaultConnector());
//     }
//
// Where |RunSomeClientCode()| would typically be some production code that
// expects a functioning Connector and uses it to connect to the service you're
// testing.
