  • Request Spec Realistic Error Response

    I didn't figure out how to resolve this on my own. I only came across a solution by searching for others' approaches. I found this issue in rspec-rails's issue tracker. In there Michael Gee shares a workaround. The earliest reference to this approach that I can find is from Eliot Sykes in 2017. If you're aware of an earlier reference to this, let me know!
  • Who's using Rails 7 test

    The rspec-rails gem falls back to rails' minitest code to do some things and there are some bugs with lifecycle hooks for example, check here and that needs workarounds, because rspec tests don't have the exact same lifecycle than minitest tests.

  • The Perils of Parallel Testing in Ruby on Rails
    2 projects | | 30 Mar 2022
    Let's get one thing out of the way. If you use RSpec rather than Minitest, you are out of luck. RSpec does not support Rails 6 built-in parallel testing. There is an ongoing discussion about changing that, but there hasn't been any significant progress for a while. If you want parallel tests with RSpec, your best bet is still using third-party gems such as grosser/parallel_tests.
