- In states.user.present, differentiate between None and empty list for
'groups': The empty list means the equivalent to passing '-G ""' to usermod,
i.e. remove all but the default group.
- In modules.useradd, always quote the value passed after the '-G' switch to
usermod and useradd, so they don't fail when we pass an empty string.
* Added `assertReturnSaltType` which is dictionary for non errors.
* Added `assertReturnNonEmptySaltType` which does the above and makes sure it's not empty.
* Fix `tests.integration.states.user.UserTest` which was using wrongly using `assertSaltTrueReturn` on 'user.info' calls.
* The `RedirectStdStreams` tests helper will allow to temporarily catch `stdout` and `stderr` output. Right now it's only used to **mute** the `tests.integration.runners.jobs.ManageTest.test_active()` output.
The remove command in the file module had guard, `os.path.exists`, in
front of all remove actions. That guard failed on broken symlinks, i.e.
it returned `false` even though the broken symlink existed. Since the
remove actions are properly guarded without the `os.path.exists` guard,
this commits removes it. Now the remove command will also remove broken
symlinks.
* Implement `SaltReturnAssertsMixIn.assertSaltNoneReturn` used in `tests.integration.states.cmd`.
* Migrate `tests.integration.states.cmd` to use `SaltReturnAssertsMixIn`.
* Expose what's happening in `integration.states.user.UserTest.test_user_if_present_with_gid()`.
* Update code that was using the old `SaltReturnAssertsMixIn`.
* Do proper type checking for salt calls, ie, a dict should be returned, if not, it's a failure, usually errors come as lists, show that to the user.
* Iterate through the salt call parts to make sure result is true, and if not, fail showing the part comment.
* In `salt.modules.pip.install()` we first check if file is already cached(in case being called from `salt.states.virtualenv.managed()`), if it's not, then try to cache it.
* If requirements and `runas` is passed, since `salt.fileclient`'s cache needs to be private, we create a temporary file with the contents of the requirements file, owned by the `runas` user, which then gets passed to the pip command.
* Always delete the user, even if test(`integration.states.virtualenv.VirtualenvTest.test_issue_1959_virtualenv_runas`) fails.
* Minor PEP-8.
* Created a mix which tests for the required assertion(True/False) and in case of a failure, shows salt comment kwarg in the raised assertion error so we know what was the original(salt's) failure.
* We basically copied subprocess from python 2.7 and import that one instead of the python 2.6 subprocess to run the tests. Since we import it under a different name, there should be no issues with the remaining of salt's source importing the regular subprocess module.
