# Do not add any other code from here until the end of this code

#
# Before ANYTHING else happens, this must happen:
#
# 1) require minitest/autorun
# 2) require rspec/core/dsl
# 3) override RSpec::Core::DSL.expose_globally! to do nothing.
# 4) require rspec
#
# Explanation: eventually, our tests get around to inspec/runner_rspec
# (and a few others), and they load rspec. By default, when rspec
# loads, it creates it's own global `describe` method, overwriting
# minitest's.
#
# Another aspect of rspec's expose_globally! is that it also messes
# with mocha's methods. Any tests that occur after our runner has run
# RSpec::Core::ExampleGroup.describe will fail if they use any mocha
# stubs (specifially any_instance) as the method will be gone. Don't
# know why, but the above sequence avoids that.
#
# Before this, the tests would get to the point of loading rspec, then
# all subsequently loaded spec-style tests would just disappear into
# the aether. Differences in test load order created differences in
# test count and vast differences in test time (which should have been
# a clue that something was up--windows is just NOT THAT FAST).
