I mean, let's think this through.
They're telling us that their "innovative development process" is to build software without even considering how to test it, and then asking a different group of people, who were not involved in development, to test it for them manually.
That is the V-model.
Once you realize that you waste more time debugging than actually writing test code, then you see the value of TDD :)
You only have this problem if you try to fix the bugs, tho. 😅
They are one step ahead of you, man!
