I'd like to know if there is a method/gem/script that allows automating checking the compatibility of gems when upgrading ruby from v2.0.0-p247 to v2.4.6. I have run the bundle install which made me update a few of them and also, I ran my tests with rake and all are OK, but I'm not so sure if I can get further issues down the road.

    How do you know that your *current* code is 100% perfect, and will not "run into issues down the road"? – Tom Lord Jan 05 '20 at 11:41

    The answer to both questions is the same: You don't know. But there are several things you can do to improve the application reliability, such as: You can peer-review the code; you can write automated tests; you can QA the application; you can use tooling to monitor errors in production; you can obtain feedback from end-users of the application, if they see some unexpected behaviour. – Tom Lord Jan 05 '20 at 11:44

    ...And if some issue is discovered that wasn't covered by any automated tests, you could *add a regression test* along with the fix. – Tom Lord Jan 05 '20 at 11:46
  • Closing as duplicate doesn't help much when there's no completely helpful answer in the linked question. – Eric Duminil Jan 05 '20 at 17:58
