# rostest include ros node as dependency

How do you include a ros node in your ROS_WS/src directory into your rostest unit tests? project_i_depend_on is just a simple ros node I wrote to reuse test fixture code in multiple projects, but I can only reference it if I include it as a relative directory which is super hacky:

#include "../../project_i_depend_on/include/project_i_depend_on/stuff.h"

Here's my rostest cmake:

if(CATKIN_ENABLE_TESTING)
#  find_package(rostest REQUIRED)
find_package(catkin REQUIRED COMPONENTS rostest project_i_depend_on)

${PROJECT_NAME}_tests # TODO: why cant we file glob here to get test sources? test/${PROJECT_NAME}_tests.launch
test/my_tests.cpp
src/my_source.cpp
)

# inject the test/resources directory into the header template, producing a reference for it the tests can use
include_directories(${CMAKE_BINARY_DIR}) target_link_libraries(${PROJECT_NAME}_tests
${catkin_LIBRARIES}${OpenCV_LIBS}
)

${PROJECT_NAME}_tests${PROJECT_NAME}
