Rspec-core: Multiple types of specs in metadata

Created on 24 Oct 2016 · 3Comments · Source: rspec/rspec-core

I'd like to define multiple types of specs for metadata, but it isn't currently possible.

I'd like to define things like:

config.when_first_matching_example_defined(types: %i(feature request)) do
  # enable db support only for feature or request specs
  require 'support/db'
end

# include these Helpers only into feature or request specs
config.include(Helpers, types: %i(feature request))

Currently I have to duplicate the definitions.

config.when_first_matching_example_defined(types: :feature) do
  require 'support/db'
end

config.when_first_matching_example_defined(types: :request) do
  require 'support/db'
end

config.include(Helpers, type: :feature)
config.include(Helpers, type: :request)

I don't think that above solution improves readability and in spec/rails_helper. Some one-liner solution would be great for these cases. I don't think, I'm alone who would appreciate something what I proposed.

You can do this:

%i(feature request).each do |type|
  config.when_first_matching_example_defined(type: type) do
    # enable db support only for feature or request specs
    require 'support/db'
  end

  # include these Helpers only into feature or request specs
  config.include(Helpers, type: type)
end

Given how easy it is to do with a simple loop, I don't see a reason for us to add support for what you're asking for--particularly since it would be a very implicit, confusing way for metadata to match, IMO.

Given that currently we treat metadata values as simple values, it would really be confusing to start giving them special meaning, not to mention ambiguous!
