Can I change the randomisation seed each run in Rspec with Guard/Spork?

Question

I'm currently using Rspec for testing, along with Guard and Spork for convenience. I've noticed that unless I quit and restart Guard, the random seed does not change between runs. While this is not a major issue, it would be handy if it did.

Anyone know of a way to change things so that it does use a new seed each time it runs the tests??

Answer 1

I added the --order rand:$RANDOM flag to my Guardfile:

guard 'rspec', zeus: true, cli: '--color --order rand:$RANDOM' do
  watch(...)
end

Answer 2

Yes, the following works for me. Add to spec_helper.rb:

Spork.each_run do
  RSpec.configuration.seed = srand && srand % 0xFFFF
end

From here.
