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).
