Defined in:
lib/whitestone.rb

.call(block, sandbox = nil) ⇒ Object

Whitestone.call

Invokes the given block and debugs any exceptions that may arise as a result. The block can be from a Test object or a “before-each”-style block.

If an assertion fails or an error occurs during the running of a test, it is dealt with in this method (update the stats, update the test object, re-raise so the upstream method execute can abort the current test/scope.
