Expected Behavior
As folks make changes to the Elafros API, e.g. updating labels, we should make sure the conformance tests cover this behavior. At the moment I need to keep up with these changes and update the conformance tests myself. It may be better to have the folks who make the changes update the tests, however it's not 100% clear when contributors would need to do that, so if we want contributors to make the changes, we need to clearly define when they should do so.
Actual Behavior
I keep up with these changes and update the tests usually, though sometimes folks are pro-active about it (thanks @tcnghia !).
