@surajssd @kadel Do you have idea why my PR pulling down the coveralls ? :-(

[kadel]

@ngtuna because you added new lines that are not covered by tests :-)

[ngtuna]

@kadel oh now I got it. Test is coming up.

[kadel]

@ngtuna I'm not sure if this can be currently tested properly without mocking kubernetes :-( or starting cluster.
But it would be great if you have any idea how to do it.
Otherwise I wouldn't worry about in this PR. We will have to figure out a way how to test up for everything later.

[ngtuna]

@kadel Right. I made this commit last night but then came up with no idea how to add a test. Will investigate it more late today.

Same thing should be added to OpenShift transformer

We have to figure out how to test up/down automatically , but that is another issue.
