That looks good. Quite a number of tests which are concerned :)

So far we've always developed new features on individual branches (within
our forked repos) and had them pulled into master afterwards. That way
master was always relatively stable and had a good quality.

This would change if we integrate individual changes of the method
validation work into master. IMO this wouldn't be a problem per se, as long
as we only work on HV-571. But we might get problems if we decide to work
on further, unrelated issues in parallel. For instance we wouldn't
recognize that such a change causes one of the tests disabled for HV-571 to

I think the new situation is that more than one person is working on the
same feature. Have there been similar cases in Search etc.? How was it
handled there? Personally I think a HV-571 feature branch in the master
repo would be a good thing to integrate and stabilize our work, leaving the
opportunity to work on other things as well, should that need arise. Also
it shouldn't necessarily be more complex than pushing to master (at least
as long as there isn't too much other traffic on master).

Sounds good to me, then I'll start with the validation methods.

+1. I think I'll start tomorrow. Regarding the current proprietary API, I
see no way we can keep it, as for instance there are methods in the BV API
with same names but with different return types. So I think we should
remove it completely. WDYT?
