Configuring Python nose tests

Nosetest is the framework for running Python unit tests. No ROS environment is available. See: Configuring rostest if your tests need a running roscore.

CMakeLists.txt

Declare each nose test like this:

if (CATKIN_ENABLE_TESTING)
  catkin_add_nosetests(tests/test_your_node.py)
endif()

This example assumes your tests are defined in the tests/ subdirectory in your source tree.

You can also let nosetest find all tests recursively:

if (CATKIN_ENABLE_TESTING)
  catkin_add_nosetests(tests)
endif()

If you used a message of the current package in the nosetest, make sure to specify the nosetest like this:

catkin_add_nosetests(tests/test_your_node.py
                     DEPENDENCIES ${${PROJECT_NAME}_EXPORTED_TARGETS})

If you used messages from other packages, use:

catkin_add_nosetests(tests/test_your_node.py
                     DEPENDENCIES ${catkin_EXPORTED_TARGETS})

The test will then make sure that the messages used in the test are built before they are used.
