Error using a YAML config file with Python nosetests

Question

def __init__():
    with open("config.yaml", 'r') as yamlfile:
        cfg = yaml.load(yamlfile)
        self.obj = TestMe(cfg.get("general", "user"), cfg.get("general", "passwd")

My YAML File looks like this

general:
  user : admin
  passwd : admin

I run the test like this

"nosetests test.py --exe --with-xunit --tc-file config.yaml"

I get the following error:

Traceback (most recent call last):
  File "/usr/local/bin/nosetests", line 9, in <module>

u'general:\n'

I am confused because on Python CLI i can read the file without any issues.. ?!

The docs suggest that nose-testconfig assumes a INI file on default. You'll need to explicitly tell nose that it's a YAML file:

nosetests test.py --exe --with-xunit --tc-file config.yaml --tc-format yaml
