Hey @filip:
Between Creating DEX and Creating Wallet Test there’s a chapter missing.
In Creating DEX you announce some reading on Test Driven Development.
However, in Creating Wallet Test the reading is already required, and the links are missing.
Can you please re-insert the chapter? And post it here?
Thanks,
Raphael

I have added a link resources for the unit test development, you were right when filip mention to learn about them but we forgot to add the link, nice catch 
and thank you for notified it.
