When functional tests are run in tox and an exception is raised when connecting
to Swift (for example: Swift not running, missing python-keystoneclient package
used by python-swiftclient) 0 tests are executed, but tox returns a success.
An exception is raised during tests, caused by a missing python-keystoneclient
in python-swiftclient. Instead of adding python-keystoneclient as a dependency
in python-swiftclient the package is added to the test-requirements.txt in Swift
itself. Note that adding python-keystoneclient to the test-requirements in
python-swiftclient is not sufficient (it's already in there).
The exception in setup_package() is catched by the openstack.nose_plugin, thus
disabling this plugin for now as well.
Also fixing two test errors seen on the gate regarding the tempurl middleware.
There was also an update to tox, environment variables were no longer passed
with versions >= 2.0 (http://tox.readthedocs.org/en/latest/changelog.html).
Swift test environment variables have been added to the passenv to re-enable the
former behavior, as well as environment variables required to pass proxy
settings.
This also led to skipped tempauth tests, and together with the missing
python-keystoneclient no tests were executed.
