Same story here with at the end not being able to use TDD.
I used to develop naturally close to the TDD way. I would create a function, test every scenario manually and once it worked, move on to the next bits of code.
When TDD became popular and I heard of it (many years ago), I was super excited and wanted to try that, only to be told we could not do that.
At the time, processes and technologies were strictly controlled in the industry I worked in (finance).
I gave up pushing for it.
Then, a few years later, I became tech support in a different company and industry and I saw they were using unit tests so at least I can say I've read test units, even if I've never created them.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
