compat.doctest.OutputChecker API [rev. unknown]

class OutputChecker():

A class used to check the whether the actual output from a doctest example matches the expected output. `OutputChecker` defines two methods: `check_output`, which compares a given pair of outputs, and returns true if they match; and `output_difference`, which returns a string describing the differences between two outputs.

methods:

def check_output(self, want, got, optionflags):

Return True iff the actual output from an example (`got`) matches the expected output (`want`). These strings are always considered to match if they are identical; but depending on what option flags the test runner is using, several non-exact match types are also possible. See the documentation for `TestRunner` for more information about option flags.

def output_difference(self, example, got, optionflags):

Return a string describing the differences between the expected output for a given example (`example`) and the actual output (`got`). `optionflags` is the set of option flags used to compare `want` and `got`.
