I'm currently writing unit / integration tests for my nodes and i'm stuck adding them the the build scripts. When running

rostest my_pkg tests.test

I get the following error

[Testcase: testtest_vehicle_controller] ... FAILURE!
FAILURE: Test node [my_pkg/test_vehicle_controller.py] does not exist or is not executable
  File "/usr/lib/python2.7/unittest/case.py", line 329, in run

    self.fail(message)
  File "/usr/lib/python2.7/unittest/case.py", line 410, in fail
    raise self.failureException(msg)

[testtest_vehicle_controller][failed]

SUMMARY
 * RESULT: FAIL
 * TESTS: 0
 * ERRORS: 0
 * FAILURES: 1

ERROR: The following tests failed to run:
 * testtest_vehicle_controller

my tests.test file looks like this

<launch>
  <test test-name="test_vehicle_controller" pkg="my_pkg" type="test_vehicle_controller.py" />
</launch>

my package structure looks like this

├── CMakeLists.txt
├── include
├── package.xml
├── src
│   ├── __init__.py
│   ├── __init__.pyc
│   ├── main
│   │   ├── __init__.py

├── srv
│   └── ManipulatorPosition.srv
└── Testing
    └── Temporary
        ├── CTestCostData.txt
        └── LastTest.log

I don't see what I'm doing wrong here

edit:

my test_vehicle_controller.py looks like this

#!/usr/bin/env python
import unittest
PKG = 'my_pkg'
import roslib; roslib.load_manifest(PKG)

class AdvancedTestSuite(unittest.TestCase):
    """Advanced test cases."""

    def test_thoughts(self):
        self.assertIsNone(None)


if __name__ == '__main__':
    import rostest
    rostest.rosrun(PKG, 'test_vehicle_controller', AdvancedTestSuite)

Is test_vehicle_controller.py executable? Does it have the x bit set in ls -al test_vehicle_controller.py?

yes it does (-rwxr-xr-x). I have the feeling that the path is not correct, but I have no idea what I need to change

When using catkin-tools you have to execute

catkin build pkg_name --catkin-make-args run_tests

Then the tests can be executed using

rostest pkg_name test_file.test

See also the catkin documentation for building and running tests

To run a catkin test for a specific catkin package, from a directory within that package:

catkin run_tests --no-deps --this

See also this answer using catkin_make.
