Point out everyone else's bullshit. Some people will tell you you are mean or you lack soft skills or that they can no longer work with you and you should go to see a therapist, but oh well, you are an engineer not their mom. You are just being rational.

Today I read a great article on mutation tests, how to use and why they are important. It looks like a great thing, but...
I have never wrote any unit test in any of my jobs. Nobody in my workplace does that. And now it seems like 100% test coverage is not enough (I remind you, that I have 0%), they all should mutate to check if the quality of unit tests is high.
It seems that I'm left behind. I played with tests in my free time, but it seems the more you write them, the better you get at it, so I should be writing them in my job, where I code most of my time. Not only that, of course, I would also want to ensure that what I'm working on is bug-free.
Still, it will be impossible to introduce unit tests to my project, because they are novelty to the whole team and our deadlines are tight. The other thing is, we are supposed to write minimum viable product, as it is a demo for a client, and every line of code matters. Some might say that we are delusional that after we finish demo we will make things the right way.
Did any one of you have a situation like this? How did you change your boss and team's mind?

I went to a job interview about 3 weeks ago. I got an email that I didn't pass, so I asked for a feedback. Their response was that I have required technical skills, but the reason I was not accepted was "your personality is incompatible with our team". I mean, WTF. How can you get my personality after one hour of me talking about code?

That's why I never believe common sense when I write Javascript.

It's about a guy that knows better.

I was working as a subcontractor on a bigger system. We (subs) were not allowed to deploy code, we had to wait for contractor to deploy.

One day I got an email that my code is bugged and that my feature is not working on production. I checked it on test env, everything was fine. Then I checked if the code I wrote was deployed. It was not.

I send an email explaining that if they deployed my code it would be working. Then I got a response. There was a bug in my code.

Another email. I asked how would they know? Do they have a test on their environment that failed?

No. There is one guy that READ my code and he said it should not work, so he will not deploy it. He was not a programmer, he was a business consultant responsible for the documentation.

His issue was that I used a function that was not in a class. So if the function is not declared it's obvious it will not work. I had to explain to him in another email, that you can use object of another class inside your class and then call a function, that is not in your class. It was the last time this guy blocked my deploy.

TL;DR, I had to explain a non-dev how object composition works in order to have my code deployed. Took four emails.
