How enable ellipsis when calling Python doctest?
You can pass in optionflags to the testmod method, but this requires you to run the module itself instead of the doctest module:
def foo(): """ >>> foo() hello ... """ print("hello world")if __name__ == "__main__": import doctest doctest.testmod(verbose=True, optionflags=doctest.ELLIPSIS)Output:
$ python foo.pyTrying: foo()Expecting: hello ...ok1 items had no tests: __main__1 items passed all tests: 1 tests in __main__.foo1 tests in 2 items.1 passed and 0 failed.Test passed.
You can enable options for an individual example like this:
'''>>> 'foobarbaz' # doctest: +ELLIPSIS'foo...baz''''The doctest directives documentation is hard to understand because the actual directives seem to be parsed away and aren't visible. There is an open bug report for this. In the meantime you can view the raw documentation source instead.
Since Python 3.4, you can pass the option with the -o flag:
$ python -m doctest -o=ELLIPSIS foo.pySource: https://docs.python.org/3/library/doctest.html#option-flags
