This is a plugin for python-nose which locks test execution and doesn't allow to run them in parallel from two terminals.
You could want this behaviour, when parallel tests will interfer for some reason. This could be because they go into one database or have other side effects which hard to isolate.
Install via pip install nose-lock, then run tests
with argument --with-lock.
By default, lock is created as /tmp/<cur-dir-name>.lock file,
but you could override this behaviour using optional parameter
--lock-file:
nosetests --with-lock --lock-file /tmp/blah-minor
