./run_tests fails

[mthaddon]

I've just downloaded the charm code, and from looking in the README.md I tried running the tests, but got:

$ ./run_tests 
tests.test_charm (unittest.loader._FailedTest) ... ERROR

======================================================================

Did you create the virtualenv and added dependencies as it specifies de "Developing" section previous to "Testing"?

@mthaddon Is this still an issue ? Or may I close this issue ?
