It took me a few minutes poking around on the RubyDocs to figure out the actual syntax for pulling this off. Figured I’d toss it here to save some future person a few clicks.
From inside your test, simply call the skip() method, like so:
skip("reason for skipping the test")
The method is MiniTest::Assertions#skip – http://docs.seattlerb.org/minitest/Minitest/Assertions.html#method-i-skip
