Tests also cost money to write and to maintain. It's a tradeoff. Personally I like to work at places where the tradeoff falls in favour of writing tests. But I understand there are some businesses that just don't have a lot of money and where the cost of things breaking isn't that high, and then the right decision might be to skip tests. And one might argue if the customers don't notice it's broken, does it really matter?

I agree they cost something, although I think they give back far more than they take. In this case though, I would say that not having them in place means people won't adopt these proffered microservices, as everyone will have to individually implement tests around them.
