 """Tests for the ipdoctest machinery itself.
 
 Note: in a file named test_X, functions whose only test is their docstring (as
 a doctest) and which have no test functionality of their own, should be called
 'doctest_foo' instead of 'test_foo', otherwise they get double-counted (the
 empty function call is counted as a test, which just inflates tests numbers
 artificially).
