Test node does not exist error in GTest / ROSTest

I am testing a ROS project using catkin_make and make. But I am having trouble finding my test node through my CMakeLists.txt and launch file. My test cases never run because of this issue.

The following is the section relevant to google testing in my CMakeLists.txt. Assume all other aspects (not shown here) of my project in CMakeLists.txt are perfect.

if(CATKIN_ENABLE_TESTING)
  find_package(rostest REQUIRED)
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g -O0 --coverage")
  add_rostest_gtest(tinynomadTest test/tinynomadTest.launch     test/tinynomadTest.cpp test/NavigationTest.cpp 
                    test/VisionTest.cpp test/TurtlebotTest.cpp src/Navigation.cpp  
                    src/Vision.cpp src/Turtlebot.cpp)
  target_link_libraries(tinynomadTest ${catkin_LIBRARIES} ${GTEST_LIBRARIES} pthread)
  add_dependencies(tinynomadTest ${catkin_EXPORTED_TARGETS})
  set_target_properties(tinynomadTest PROPERTIES LINKER_LANGUAGE CXX)
endif()

The following is my launch file tinynomadTest.launch :

<launch>
 <node name="tinynomad" pkg="tinynomad" type="tinynomad" output="screen"/>
 <test pkg="tinynomad" test-name="tinynomadTest" type="tinynomadTest" />
</launch>

This is my project structure :

Would you enlighten me what is wrong ?
