This is a demo repo to reproduce the issue described here

Steps to reproduce

Guard / Spork interfering with rspec run on terminal

1. Open 2 Terminal windows
2. In one, type rspec

• Should get 2 examples, 0 failures

3. In second window, type guard to start guard & spork
4. Press enter to run suite

• Should still get 2 examples, 0 failues;
• but get 2 failures "undefined method `validate_presence_of' for #RSpec::Core::ExampleGroup::Nested_1:0x00000103552ab8"

5. In first window, again type rspec

• Expect tests to pass
• but see same error as in guard

6. In second window, type exit to quit guard
7. In first window, type rspec, behavior back to normal.
