I can't even print debug messages for testing?

wtf...!?

Moreover:

this is plain shit post kata:

• no sample test
• only 2 tests
• the assertion message doesn't make ANY sense
• the assertions doesn't not take into account what the user is returning
• you use mutation sowewhere you shouldn't

Seriously, considdering the kata you created recently, you should stop trying to do so unless you improve yourself at this. currently, it's pretty far from a good job.

Hi, that's a duplicate, sorry.
