# deterministically_verify executes the test provided in the block successive
#   times with the same deterministic_random seed.
# @param subject_proc [Proc] a proc object that returns the subject under test
#   when called.
# @param depth [Integer] the depth of deterministic comparisons to run; the default value is 2.
# @param seed [Integer] A random number seed; Used to override the default value which is 42.
