Is this a pattern? Does it have a name? It allow swapping out basically the whole behaviour of the `Thing`.
class Thing
def self.runner=(custom_runner)
@runner = custom_runner
end
def self.runner
@runner ||= new
end
def run(*args)

There's no way to definitively run a single test using MiniTest as it currently stands.

(Here's my proposed fix for this)

First, print out the test names:

$ ruby minitest.rb -v                 
Run options: -v --seed 58440

# Running tests:

AnotherTest#test_something = 0.00 s = F

ruby-1.9.3-p194 cumulative performance patch.
