Nose print bug fixed

I fixed the nose print bug, where the first run of a test with a print statement would pass but any run thereafter would fail.

Get the fix here:

If you see this error, then you need to checkout my fix:

ERROR: test.test
———————————————————————-
Traceback (most recent call last):
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/nose/case.py", line 188, in runTest
test(*self.arg)
File "/Users/along/Desktop/nosetest/test.py", line 2, in test
print("hello")

_complain_ifclosed(self.closed)
TypeError: ‘NoneType’ object is not callable

The fix lies in editing capture.py to remove the two commented items from start()

    def formatError(self, test, err):
        """Add captured output to error report.
        """
        test.capturedOutput = output = self.buffer
        #COMMENT THIS LINE BELOW
        #self._buf = None
        if not output:
            # Don't return None as that will prevent other
            # formatters from formatting and remove earlier formatters
            # formats, instead return the err we got
            return err
        ec, ev, tb = err
        return (ec, self.addCaptureToErr(ev, output), tb)

Also for good measure, change
from StringIO import StringIO
to
from cStringIO import StringIO
