guard with parallel_tests fails

[i0n]

I get the following output when configuring guard to use parallel_test.parallel_tests runs normally through rake.

/Users/i0n/.rvm/gems/ruby-1.9.3-p392@global/gems/parallel_tests-0.10.0/lib/parallel_tests/cli.rb:65:in parse_options!': invalid option: -f (OptionParser::InvalidOption) from /Users/i0n/.rvm/gems/ruby-1.9.3-p392@global/gems/parallel_tests-0.10.0/lib/parallel_tests/cli.rb:6:inrun'

Looks like it is trying to pass RSpec options to parallel_tests?

The configuration looks like this:

guard 'rspec', :parallel => true, :parallel_cli => '-n 2' do
.... stuff....
end

Gems:

rspec: 2.13.0
parallel_tests: 0.10.0
guard: 1.6.2
guard-rspec: 2.5.0

Could you try with the just released version 2.5.1 ?

[i0n]

Yes it works now. Thanks!

@thibaudgg I'm still getting this error (invalid option: -f (OptionParser::InvalidOption)) when using parallel_tests when all specs are run, but only after a single spec is run using zeus:

guard :rspec, zeus: true, run_all: { parallel: true, parallel_cli: '-n 4' } do
  # ...
end

Versions:

guard (1.8.2)
guard-rspec (3.0.2)
parallel_tests (0.15.1)

Any ideas?

[thibaudgg]

And with just zeus & parallel_tests (without guard) you didn't get it?
Have you ~/.rspec or smilier file somewhere with the -f params?

[kainosnoema]

@thibaudgg zeus works fine on it's own, parallel_tests works fine on its own, and both work fine with guard actually, as long as they're both enabled for all tests. It's the exact configuration above that fails, and only when I run a single spec without parallel_tests first, then try running all specs with parallel_tests. It's almost as if the configuration is getting cached or munged somehow from the previous run.

I do have an .rspec file in the project root, and it has the --format option specified (not the shortened -f version).

[thibaudgg]

Really strange edge-case, I don't use zeus or parallel_tests so I don't know how to fix it.
Have you try to change/remove your .rspec file?

I'm having the same issue... any ideas where to start debugging?
