Running a single spec

[eeng]

While running with autospec (-a) sometimes I need to run a single test (for example, to see the log produced only by that test). Is there a way to "focus" on a particular test?
In Rspec that can be done with tags in conjunction with the run_all_when_everything_filtered setting.
It could be nice to have something like the xit macro but for focusing on individual tests (maybe named "fit"?).
Sorry if there is already another way to do this, but could find it on the docs.

Thanks for this library by the way.
