cmdtest is a simple way to test command line programs.

from cmdtest import Program, File

cat = Program('cat')

@cat.test
def cat_should_echo_single_file():
    assert cat(File('hello')).out == 'hello'

@cat.test
def cat_should_combine_files():
    assert cat(File('hello'), File('world')).out == 'helloworld'

if __name__ == '__main__':
    cat.run()
