Why seems add_rostest not to work?

Question

I am migrating a packet to catkin. It contains a test. The test runs successfully like this:

rostest my_navigation_test my_test_4_cob.test

but when i add

add_rostest(launch/my_test_4_cob.test)

to the equivalent CMakeLists.txt and call catkin_make test I get:

catkin_make test

0% tests passed, 1 tests failed out of 1

Total Test time (real) =   5.66 sec

The following tests FAILED:
      1 - _ctest_my_navigation_test_rostest_launch_my_test_4_cob.test (Failed)
Errors while running CTest
make: *** [test] Error 8
Invoking "make" failed

It is a bit hard to debug as it gives no feedback about what is really happening at all.
Any ideas?

Can you explain to me what the line '_ctest_my_navigation_test_rostest_launch_my_test_4_cob.test' means? Does it expect the launchfile to be called like this? (which it isn't)

This might has been my fault, because i messed up my multiple workspaces. But I'll check it

Answer 1

Use catkin_make run_tests, rather than just test.

See the how-to run tests documentation.

Thank you. This helps a lot as I can see the test output

You can also call catkin_test_results to get a summary of tests.
