Returns the code block with any ``__future__`` import lines sorted, and
then any ``future`` import lines sorted, then any ``builtins`` import lines
sorted.
This only sorts the lines within the expected blocks.
See test_order_future_lines() for an example.

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.

Strips any of these import lines:
from __future__ import <anything>
from future <anything>
from future.<anything>
from builtins <anything>
or any line containing:
install_hooks()
or:
install_aliases()
Limitation: doesn't handle imports split across multiple lines like
this:

unicode_literals)

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 ...
for the purpose of the comparison.

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)
