opal (~> 0.11.0)
opal-rspec (0.7.0.rc.2)

I try to run specs in browser.
when run bundle exec rackup command,the error occurs.

config.ru

require 'bundler'
Bundler.require
require 'opal/rspec'
sprockets_env = Opal::RSpec::SprocketsEnvironment.new(spec_pattern='spec/opal/*_spec.{rb,opal}')
run Opal::Sprockets::Server.new(sprockets: sprockets_env) { |s|
  s.main = 'opal/rspec/sprockets_runner'
	s.append_path 'spec/opal'
  sprockets_env.add_spec_paths_to_sprockets
  s.debug = false
}

Can confirm. I have the same issue with version '0.7.0.rc.2'

Please try adding a require 'opal/platform' in your spec or spec_helper and see if it works.

[anharu2394]

tha same error occured again.

My spec_helper.rb

require "bundler/setup"
require "rubelm"
require "opal-browser"
require 'opal/platform'

RSpec.configure do |config|
  # Enable flags like --only-failures and --next-failure
  config.example_status_persistence_file_path = ".rspec_status"

  # Disable RSpec exposing methods globally on `Module` and `main`
  config.disable_monkey_patching!

  config.expect_with :rspec do |c|
    c.syntax = :expect
  end
end

How is the problem solved?

[elia]

Ok, found a temporary solution

add spec/opal/custom_sprockets_runner.rb with this content:

require 'opal'
require 'opal/platform'
require 'opal/rspec/sprockets_runner'

then replace the main file in config.ru with opal/custom_sprockets_runner.rb

---

meanwhile I'll fix it on master, let me know how it goes 👍

[anharu2394]

I 'll try it.

My config.ru

require 'bundler'
Bundler.require
require 'opal/rspec'
sprockets_env = Opal::RSpec::SprocketsEnvironment.new(spec_pattern='spec/opal/*_spec.{rb,opal}')
run Opal::Sprockets::Server.new(sprockets: sprockets_env) { |s|
  s.main = 'opal/custom_sprockets_runner.rb'
	s.append_path 'spec/opal'
  sprockets_env.add_spec_paths_to_sprockets
  s.debug = false
}

My spec/opal/custom_sprockets_runner.rb

require 'opal'
require 'opal/platform'
require 'opal/rspec/sprockets_runner'

But running bundle exec rackup,the error occured.
RuntimeError: Cannot find asset: opal/custom_sprockets_runner.rb

I edit config.ru

require 'bundler'
Bundler.require
require 'opal/rspec'
sprockets_env = Opal::RSpec::SprocketsEnvironment.new(spec_pattern='spec/opal/*_spec.{rb,opal}')
run Opal::Sprockets::Server.new(sprockets: sprockets_env) { |s|
  s.main = 'custom_sprockets_runner'
	s.append_path 'spec/opal'
  sprockets_env.add_spec_paths_to_sprockets
  s.debug = false
}

And, I can successfully run bundle exec rackup

Thank you very much!!!!!!!!!

[elia]

yeah sorry, I got the path wrong 😄

Anyway I pushed the fix to master, you should be able to use the original code by pointing to the github gem in your Gemfile:

gem 'opal-rspec', git: 'https://github.com/opal/opal-rspec', submodules: true
