The way micronaut currently works is that when you tag an example or
example group as "focussed" autotest will only run those. So you are
overriding it's default behaviour and not running the entire suite.

Yeah, it is a process and that is what I like about it. When working on
a large suite it is impractical to run the entire suite in conjunction
with autotest. So, you end up running them by hand. I really like
using autotest though and so by providing this feature one can still use
autotest in there workflow/process when working on new functionality in
a large project.
I haven't used it too much, but it seems like a really useful thing to
have. Having autotest act on multiple tags may get too complicated, but
I think the "focussed" tag is pretty straightforward.
