Rails, is it necessary to run tests when deploying to Mina or Capistrano?

Question

Ruby on Rails

I read the article

I think tests are needed during deployment.
Now we are running tests in Travis Сi, after each push to the git branches and publishing to the slack.
But let's say programmer A didn't look at the tests and pushed to production?
Can run tests in a deploy with a test database while pushing to production?
Or the right way.
I need opinions, I want to understand how to do it right.

Answer 1

Right the way you like it.
We use bitbucket pipelines. When the tests fail, the deployment is not available. On staging, deployment is automatic, and on prod - by click.
