[openlp-dev] Moving to Nose 2

[Raoul Snyman]

Hi guys,

As of a few years ago, Nose[0] (our test runner) has been in 
maintenance. I've been looking into moving to Nose2[1], and I've got a 
branch[2] with changes to make our tests Nose2/unittest[3] compatible.

A few things to take note of:

  - Files need to be named test_blah.py.
  - Classes can be called BlahTest() and must inherit from 
unittest.TestCase (not necessarily directly).
  - Test methods MUST be named test_foo() (anything else will not be 
picked up).
  - Nose2 primarily loads from its configuration file. I've added one in 
my branch.
  - Due to the above point, running tests is now just a matter of 
"nose2-3.5" in the root directory.
  - If you do want to run functional or interface tests separately, you 
need to use dot notation instead:
    $ nose2-3.5 tests.functional
  - Every test directory needs a __init__.py in it, as they are all 
proper Python modules now.

Thankfully the changes that need to be made are backwards compatible, so 
you can still run Nose 1 on the tests and you'll be covering everything.

There is one final test that I am still trying to find which Nose2 is 
not running, but once that test is running and everything is passing 
again, I'll propose my branch for merging.
