importing a file as a package - Python

I have the following directory structure:

/testlib
    __init__.py
    ec2.py
    unit/
       __init__.py
       test_ec2.py
    utils/
       __init__.py

I'm trying to create a unittest class for ec2.py:

import ec2

class TestEC2(unittest.TestCase):

    def setUp(self):
        self.ec2obj = ec2.EC2(name="testlib_unittest")

if __name__ == '__main__':
    unittest.main()

However, when I execute test_ec2.py I'm getting the following error:

python unit/test_ec2.py 
Traceback (most recent call last):
  File "unit/test_ec2.py", line 4, in <module>
    import ec2
ImportError: No module named ec2

I still don't understand why I'm getting that, since I have the __init__.py properly set in the directory. The __init__.py files are completely empty: I've created them with touch __init__.py. Any clues?

**** Updates **** Here are some suggestions:

/testlib# python unit/test_ec2.py 
Traceback (most recent call last):
  File "unit/test_ec2.py", line 4, in <module>
    from ..ec2 import EC2
ValueError: Attempted relative import in non-package

testlib# python unit/test_ec2.py 
Traceback (most recent call last):
  File "unit/test_ec2.py", line 4, in <module>
    import testlib.ec2 as ec2
ImportError: No module named testlib.ec2

Python is not looking for files in directories above yours. Ignacio's answer is correct, and see this for elaboration.

It can't find the module because you're running the script incorrectly. Run the following in testlib/:

python -m unit.test_ec2
