unit testing - Python unittest and test discovery

Question

What exactly I need to do to make python's unittest work? I checked the official documentation, SO questions and even tried using nose, but nothing worked so far. What I'm doing wrong?

bash:~/path/to/project/src/tests$ ls -l
total 8
-rw-r--r-- 1 myuser myuser 342 Out 11 11:51 echo_test.py
-rw-r--r-- 1 myuser myuser  71 Out 11 11:28 __init__.py
bash:~/path/to/project/src/tests$ python -m unittest -v echo_test

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK
bash:~/path/to/project/src/tests$ python -m unittest discover

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK
bash:~/path/to/project/src/tests$ cat echo_test.py
import unittest

class EchoTest(unittest.TestCase):  
    def fooTest(self):
        self.assertTrue(1==1)

    def barTest(self):
        self.assertTrue(1==2)

#suite = unittest.TestLoader().loadTestsFromTestCase(TestEcho)
#unittest.TextTestRunner(verbosity=2).run(suite)

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

As you can see, the tests simply aren't run and I have no idea why(since I'm not a python programmer). Just for information, I'm using python 2.7 and the __init__.py is an empty file. Any thoughts?

You need to rename the methods to begin with the word "test".

As seen on http://docs.python.org/library/unittest.html :

A testcase is created by subclassing unittest.TestCase. The three individual tests are defined with methods whose names start with the letters test. This naming convention informs the test runner about which methods represent tests.
