Code Coverage für pytest mit ROS

Goal

Create coverage for pytest using ROS

How is this working with unittests?

A python unittest is added to the CMakeLists.txt using

catkin_add_nosetests(unittest.py)

where the CMake-Macro is defined in https://github.com/ros/catkin

here to macro checks for the environment variable CATKIN_TEST_COVERAGE and will enable the coverage flags

if("$ENV{CATKIN_TEST_COVERAGE}" STREQUAL "1")
  set(_covarg " --with-coverage")
endif()

How could/should we extend this for pytest?

A python pytest is added to the CMakeLists.txt using

add_pytest(pytest.py)

where CMake-Macro is define in https://github.com/machinekoder/ros_pytest

However inside this Macro the essential part is commented out see

Steps done

• Open PR to rosdistro for python-pytest-cover ros/rosdistro#24929

Next steps

• Open PR for https://github.com/machinekoder/ros_pytest for coverage functionality similiar to the catkin CMake-Macro
