erratic test behaviour

[timeyyy]

im interested in making this code compatible with python 2 and 3, python 3 works pretty well using 2to3.py, but the get_root() function isn't working for me.

Im using windows 7, testing is done on unaltered code from this repo

_running python2 -m py.test tests_ collected 33 items

during testing i get a few uac dialog boxes which i confirm

only ever passed once without errors, There are sometimes 2 sometimes 3 tests that are failed.

_testing with tox -e py27:_ collected 30

No uac dialog prompts

The tests pass 50% of the time under tox, when it fails its because of the error pasted below.

I'd like some guidance on my next actions, i feel i need to get the tests working 100% of the time before moving on. Not sure what the best course of action is.

Does any one know why tox is collecting different amount of tests?

mytox.ini [tox] envlist = py27, py33, py34 [testenv] deps=pytest commands=py.test

_Here is the error that gets thrown the most when running under tox and py.test_

Does any one know why tox is collecting different amount of tests?

Some tests are only activated if certain freezer programs are installed, e.g. it will only run the py2exe tests if py2exe is installed.

  return super(TestPatch_pybsdiff,self).tearDown()

Hmm...it's been a good long while since I touched this code, but I do remember the tempfile cleanup being pretty unreliable on windows. The simplest option may be to either (a) ignore errors when cleaning up tempfiles from the tests, or (b) add a loop to sleep-and-retry the rmtree call until it succeeds.

i noticed there are quite a few open pull requests, is there any way i can help close them?

@timeyyy indeed, the truth is I just don't have the bandwidth to keep up with this project these days, and since I'm not using it for any active projects anymore it's hard to make the time. If you're interested, it would be great to get your comments on any of the open PRs and we can work towards getting them merged.

As you noted here, one of the big problems with maintenance on this project is that the tests are kinda flaky. It would be great to get travis-ci or similar hooked up on here to give a bit more confidence with moving the code forward on different platforms. If you have the interest and the time, I'd be delighted to help you work towards such a setup.

:thumbsup Lets do this! @rfk im looking into setting up travis-ci, would you be able to enable it for the repo and also send a message to support requesting multi-os testing as per

http://docs.travis-ci.com/user/multi-os/ support@travis-ci.com

something like this

Hello i would like to test my repo cloudmatrix/esky on multiple operating systems.
