Hey Guys,
This is probably not specific to Rails, but I’m kinda hoping someone
already faced this error, it’s been hours trying to debug the issue, but
I just can’t figure out why it’s happening
So the application I’m developing is on Rails 3.1 using the 3-1-stable
branch, up-to-date, and I’m using latest version of all the Gems listed
in the Gemfile below…
When I run guard with the guard-spork portion commented, everything
works just fine, however, if I enable spork, I get the following error
on the second time the tests run, that’s right, the first time the tests
run like usual but If I save/touch any of the test file, rspec gets
invoked and the following error is shown (all the tests fail of course).
Any hints?
Regards,
Wael
