    This only sorts the lines within the expected blocks.

        Converts the code block using ``futurize`` and returns the
        resulting code.

        Passing stages=[1] or stages=[2] passes the flag ``--stage1`` or
        ``stage2`` to ``futurize``. Passing both stages runs ``futurize``
        with both stages by default.

        If from3 is False, runs ``futurize``, converting from Python 2 to
        both 2 and 3. If from3 is True, runs ``pasteurize`` to convert
        from Python 3 to both 2 and 3.

        Optionally reformats the code block first using the reformat() function.

        If run is True, runs the resulting code under all Python
        interpreters in self.interpreters.

        Compares whether the code blocks are equal. If not, raises an
        exception so the test fails. Ignores any trailing whitespace like
        blank lines.

        If ignore_imports is True, passes the code blocks into the
        strip_future_imports method.

        If one code block is a unicode string and the other a
        byte-string, it assumes the byte-string is encoded as utf-8.

        Convenience method that calls convert() and compare().

        Reformats the code blocks automatically using the reformat_code()
        function.

        If all_imports is passed, we add the appropriate import headers
        for the stage(s) selected to the ``expected`` code-block, so they
        needn't appear repeatedly in the test code.

        If ignore_imports is True, ignores the presence of any lines
        beginning:

            from __future__ import ...
            from future import ...

       by callable_obj when invoked with arguments args and keyword
       arguments kwargs.  If a different type of warning is
       triggered, it will not be handled: depending on the other
       warning filtering rules in effect, it might be silenced, printed
       out, or raised as an exception.

       If called with callable_obj omitted or None, will return a
       context object used like this::

            with self.assertWarns(SomeWarning):
                do_something()

       An optional keyword argument 'msg' can be provided when assertWarns
       is used as a context object.

       The context manager keeps a reference to the first matching
       warning as the 'warning' attribute; similarly, the 'filename'
       and 'lineno' attributes give you information about the line
       of Python code from which the warning was triggered.
       This allows you to inspect the warning after the assertion::

           with self.assertWarns(SomeWarning) as cm:
               do_something()
           the_warning = cm.warning
           self.assertEqual(the_warning.some_attribute, 147)
