This was introduced but never actually used. The introduction of environments.last as the fallback for unfound variables means this functionality is already broken
Ruby 1.9+ uses Minitest as the backend for Test::Unit. As of Minitest 5,
the shim has broken some compatibility with Test::Unit::TestCase in some
scenarios.
Adjusts the test suite to support Minitest 5's syntax.
Minitest versions 4 and below do not support the newer Minitest::Test
class that arrived in version 5. For that case, use the
MiniTest::Unit::TestCase class as a fallback
