Add some step test data here, please.

Done.

We do not want it to fail hard when it experiences an issue, just turn purple.
I'm not sure if this is the correct way of doing this or not.

[jbudorick, 2016/07/28 20:23:11]

I think this is ok. I'm not sure it'll cause the build to fail on its own, but I
do think it'll cause the step to go purple, and I think the steps that would run
on this will still be red and consequently fail the build.
