end

#shrunken_subsets ⇒ Object

Returns an array of “shrunken” proper subsets of the object. These subsets are intended to find simpler cases that will reproduce a test failure. WARNING: This API will likely change. We plan to experiment with it heavily. One idea is to have it take a block instead, and pass the various subsets to the block.
