Mark,<br><br>Thanks for the explanation and pointing me to the link. It makes sense to me now. "py.test -s" works for me in this case.

Hi all,<br>
<br>
I am trying to execute a remote command using fabric in my test
run by py.test. Fabric is a library for using SSH and I myself is
quite new to it and just want to start using it. The problem is
when i run it with py.test I am getting an error, but not when
invoking with python.</blockquote>

py.test is replacing sys.stdin and sys.stdout with "file-like
objects", but those objects do not have any real file descriptors.
This fileno() can't possibly return a correct value (there is no
file descriptor), so it raises an exception. The logic is that
automated tests are not interactive, so we expect them to not read
from stdin.<br>
<br>
Your program is trying to do something directly with the file
descriptor for stdin, so you can't have your test system preventing
access. You might try "pytest -s" to make it not mess with
stdin/stdout. There is a brief discussion of capturing stdin/stdout
at <a href="http://pytest.org/latest/capture.html" target="_blank">http://pytest.org/latest/capture.html</a> .<br>
