nose test freezing at raw_input

Question

I have a nose test that imports a file which runs a class with raw_inputs. Whenever I type nosetests in the command line, the prompt simply pauses and doesn't continue - I have to keyboard interrupt to see what happens, and it turns out the nose test is running my file up to the first raw_input (one of many), at which point it simply pauses and cannot continue.

Any way to bypass this? Thanks!

If possible, rewrite the file so it won't call raw_input() when imported.

# imported file
if __name__ == "__main__":
    raw_input()

Otherwise, if you can figure out in advance what would be acceptable input, you can take standard input from a file. Assuming input.txt contains "Pass":

nosetests test_input.py < input.txt

where test_input.py is:

# test file
def test_input():
    s = raw_input()
    assert s.strip() == "Pass"

Or you can pipe acceptable input into nosetests:

c:\>echo Pass | nosetests test_input.py
.
