Using a ROS Kinetic node as both a SimpleActionServer and SimpleActionClient

edit

I have a class that provides a SimpleActionServer and when I interact with it using a SimpleActionClient in another node everything works as expected. I am now trying to write a rostest case for the server class. When I run the test case the server initializes fine but the client blocks forever in waitForServer(). If I start my standalone client node it immediately connects to the server in the test case and can send a new goal.

Is running an action server and client from the same process supported? If not, how can I test my action server?

TEST(Node, testActionServer) {
  ServerClass srv;   // constructor starts the action server

  actionlib::SimpleActionClient<mynamespace::GoalAction> ac("/myActionServer", true);
  ROS_INFO("Waiting for server...")
  ac.waitForServer();
  ROS_INFO("Connected to server");

  // Do stuff like send a goal.
}

The code for creating the simple action client was copy and pasted directly from the stand alone node.
