Write unit tests #2
Description
A testing platform has been written in order to automate the verification of the smooth functioning of modules.
Now these tests has to be written in all modules so when we change something in the 'core' of pipobot we can verify quickly that no bug has been introduced.
A wiki page has been created to monitor the progress of this task : https://github.com/pipoteam/pipobot-modules/wiki/Unit-Test
