It would be good to catch a more specific exception.

@mgogoulos Bump^^

[mgogoulos]

I did some changes and pushed the tests (they've already been in test_list_nodes inside).
On my dev environment they pass, but Travis CI fails! Not sure why this happens, self.assertEqual('12.16.18.28', node.public_ips[0]) could easily be written as self.assertTrue('12.16.18.28' in node.public_ips) since the order of the ips has changed and seems to break the tests, what do you think?

[Kami]

@mgogoulos Yeah, tests shouldn't rely on some arbitrary ordering, but in this case it seems like the order should always be the same? Or am I missing something?

[Kami]

@mgogoulos In any case, I'm also fine with using in approach.

[mgogoulos]

Fixed the tests, ready to merge as I see this issue is referenced on other tickets as well (https://issues.apache.org/jira/browse/LIBCLOUD-452)

@mgogoulos Thanks.

Can you please sync this branch with trunk and squash all the commits? Currently, I can't apply patch cleanly onto trunk.

[mgogoulos]

branch synced, commits were squashed and patch has been attached to https://issues.apache.org/jira/browse/LIBCLOUD-503

[Kami]

Merged into trunk.

Thanks.
