We tried to write tests, but they took too long to run. Also there was a great debate over which of the numerous testing frameworks to choose from? Chai? mocha? Cypress for end to end? How it all fits in the CI pipeline? For unit testing, go has a great built-in solution, and with testify you can get the rest of the way there. I don't think go is a silver bullet solution, but when I see something I know can be a lot better and simpler, I generally tend to gravitate towards that.
