# This class extends TestReporter so it includes all of the tests from
# TestReporter plus any additional test_* cases below and it
# overrides create_report to use the start/stop methods
# This specifically tests the public API of the start and stop methods of the
# MemoryProfiler module itself, and even does some extra tests exercising
# edge case handling of `current_reporter` which is done in those methods.
#
# When something fails here, and not in the private api tests, then there is
# something wrong specifically in the methods handling the `current_reporter`
# that needs to be fixed.
