I'd like to write some python code that will allow me to write tests for a stage3/4 and have bug(s) be automatically closed when these tests pass. This way, instead of saying "fixed" and hoping the bug is fixed, we can get official confirmation from testing that the thing is actually fixed. This would be super-handy and could have a really positive impact on our dev process. So I think it's worth getting this in place ASAP, esp. considering that we have lxd and metro at our disposal for this.
