improved rospy core logger test. #1144
Conversation
now allowing to customize out/err streams for RosStreamHandler
|
I also modified the Guideline : keep the core as pure (functional) as possible, push side-effects to the side. |

This is a nice improvement to the tests. Thank you for your effort.
Throttled loggers need node to be initialized (to get the time...) so we might test them in a rostest instead (unless we can somehow remove that constraint)
test_rosgraph might be a good location for such tests.

Why has this test been removed?

somehow it didn't find that bug : https://github.com/ros/ros_comm/pull/1144/files#diff-84739190beb4f06aecd26a816f126e29L350
and it s now tested in context there: https://github.com/ros/ros_comm/pull/1144/files#diff-719224e090245a8163761263deeb3355R94

I see the test has been moved here https://github.com/ros/ros_comm/pull/1144/files#diff-719224e090245a8163761263deeb3355R91 (slightly different line than the above link. LGTM.

Is there a reason for these imports to not be at module level?
Same below.

Not that I know of... imports were already done in the method, I just did the same. I ll change them...

This is still pending. Maybe you are still working on this. Please let me know when I should review the patch again.

I actually missed these...
I also noticed the test_wait_for_service has a comment "lazy-import for coverage"... Is this something I should be concerned about ? I don't know how I can check coverage in this repo... any doc you could point me to, describing this ?

Please avoid empty lines after def ...(...): or try: (PEP 8).

Please make sure that lines which haven't changed do not appear in the diff.

ah sorry this happens because of my editor switching to unix endlines by default...
I ll put back the windows endlines there to get a proper diff.

Can this debug output be removed?

Should this be removed too?

I left it there to illustrate what the handlers should be. I might as well actually check it.

I was actually thinking of leaving this PR like this (except minor changes), given that throttled and named loggers are already tested in |

This doesn't work with Python 3. Please use the same conditional import as in the other files.

@asmodehn Thank you! |
now allowing to customize out/err streams for RosStreamHandler.
This is still WIP to get feedback, and we should add test for named loggers.
Throttled loggers need node to be initialized (to get the time...) so we might test them in a rostest instead (unless we can somehow remove that constraint)
FYI : I also found a mix of unix/windows endlines in rospy.core... not addressing this issue here.
