catkin build run_tests stuck in a loop.

edit

I've implemented a simpel unit test following the guide here. When I build the code using catkin build everything is fine. But when I build the tests using catkin build package_name --catkin-make-args run_tests catkin gets stuck in an infinite loop. If I remove the nodehandle in the utest.cpp file everything is fine. Help!

I'm not sure if this is a bug in catkin_tools or on my end. Hence I created an issue in the catkin_tools repository catkin/catkin_tools#517.

PS I'm using ROS kinetic, on ubuntu 16.04 (kernel 4.15.0-23).

Heres my code (test/utest.cpp):

#include <ros/ros.h>
#include <gtest/gtest.h>

TEST(TestSuite, testCase1)
{
}

int main(int argc, char **argv){
  testing::InitGoogleTest(&argc, argv);
  ros::init(argc, argv, "tester");
  ros::NodeHandle nh;
  return RUN_ALL_TESTS();
}

And here is the CmakeLists.txt:

find_package(catkin REQUIRED COMPONENTS  roscpp  std_msgs)
cmake_minimum_required(VERSION 2.8.3)
project(object_motion_prediction)
catkin_package(CATKIN_DEPENDS roscpp)
include_directories(include ${catkin_INCLUDE_DIRS})
catkin_add_gtest(utest test/utest.cpp)# src/motion_prediction.cpp)
target_link_libraries(utest ${catkin_LIBRARIES})

Additional CMake Args:

-DCMAKE_CXX_STANDARD=11 -DCMAKE_BUILD_TYPE=Release -GCodeBlocks - Unix Makefiles

The build seems to be stuck on this command:

catkin env -si  /usr/bin/make run_tests --jobserver-fds=6,7 -j

For the full output:

$ VERBOSE=1 catkin build unit_test_test -v -p1 --catkin-make-args run_tests
