I'm new to using the spring gem and have been impressed at how it has made my tests run quicker. I've followed the documentation:

  1. Included the spring and spring-command-rspec gems in the development and test groups

  2. ran $ bundle install

  3. ran $ bundle exec spring binstub --all

I have direnv, so can type rspec and it runs it with spring. So when I do

rspec ./spec/path/to/file_spec.rb

It runs it much quicker! Should I be expecting the same behaviour when I run:

$ rspec ./spec/

Because currently, it runs at the same speed as when I run it without spring.

Any pointers and advice would be appreciated, thanks.

    Tests, which can fail unpredictably, are far more likely to cause problems with spring. Unless your test suite takes a VERY long time to run then I wouldn't recommend using it -- the first time you spend half a day troubleshooting a spec only to find it's because spring kept something in memory is the last time you'll use spring. – anothermh Sep 03 '20 at 21:49
  • thanks for replying @anothermh, and for the warning. Thing is, my rspec suite takes far too long at the moment. Without spring, it takes 15 seconds to load a random test file whilst with spring it goes down to 2 seconds. I think it might be my Mac (which is slow). I'm unsure if I should continue with spring and risk tests @£$%! me off or go without it and look at getting a new mac :( – Karim Timer Sep 04 '20 at 09:42
