What is the difference between rosunit and rostest?
About rostest: Integration test suite based on roslaunch
About rosunit: an internal tool for running unit tests within ROS
But then there is an example of unit test being run by rostest.
#!/usr/bin/env python
PKG = 'test_roslaunch'
import roslib; roslib.load_manifest(PKG) # This line is not needed with Catkin.
import sys
import unittest
## A sample python unit test
class TestBareBones(unittest.TestCase):
## test 1 == 1
def test_one_equals_one(self): # only functions with 'test_'-prefix will be run!
self.assertEquals(1, 1, "1!=1")
if __name__ == '__main__':
import rostest
rostest.rosrun(PKG, 'test_bare_bones', TestBareBones)
I'm confused. What are the differences between rosunit and rostest? What are usecases for each of them?
Perhaps wiki/Quality/Tutorials/UnitTesting can provide some insight.
@gvdhoorn This article doesn't mention rosunit at all.
And that's why I didn't post it as an answer. The reference was meant to provide you with some more context in which these tools are being used.
Judging by the numerous references to rosbuild, a deprecated build system, on the rosunit page, I'm assuming that rostest is the preferred way to test.
