NoMethodError: undefined method client

[einSelbst]

Hi all,
I think I'm running out of ideas with this. I have installed rspec_api_documentation according to the docs. I'm trying to use it with rails-api.
When I add a test in "spec/acceptance/tools_spec.rb" with the following content:

require 'rails_helper'
require 'rspec_api_documentation'
require 'rspec_api_documentation/dsl'

resource "Tools", focus: :true do
  header "Content-Type", "application/json"

  let(:tool) { create(:tool) }

  get "/v1/tools/:id" do
    let(:id) { tool.id}
    example "Show tool with given ID" do
      do_request

      status.should == 200
    end
  end

I tried many variations but I always get

Failure/Error: Unable to find matching line from backtrace
     NoMethodError:
       undefined method `client' for #<RSpec::ExampleGroups::Tools_2::GETV1Tools1:0x007fcfdd69c698>

Why can't it find a "client"? I have seen the "client" mentioned in the gotchas, but I think I don't want to define my own.
I have the following in Gemfile:

source 'https://rubygems.org'

gem 'rails', '4.1.4'
gem 'rails-api'
gem 'pg'
gem 'jbuilder'
gem 'oj'
gem 'oj_mimic_json'
gem 'unicorn'
gem 'rails_12factor', group: :production

group :development do
  gem 'spring'
  gem 'debugger'
end

group :development, :test do
  gem 'spring-commands-rspec'
  gem 'rspec-rails', '~> 3.0.0'
  gem 'guard-rspec'
  gem 'rb-fsevent' if `uname` =~ /Darwin/
  gem 'rspec_api_documentation'
  gem 'apitome'
  gem 'factory_girl_rails'
  gem 'database_cleaner'
  gem 'shoulda-matchers', require: false
  gem 'faker'
end
ruby '2.1.1'

Any hints how to solve this issue would be greatly appreciated.

It's working now, but I have no idea why.

I see. The problem was in my helper I had used (all) the Configuration options listed in the Readme and assumed that # Values listed are the default values means it would be safe to just use them as is. Turned out I had to comment out the line:

config.client_method = :client

Of course, now the error message makes sense and I actually had looked at that line and the accompanying comment without realizing. Maybe it should be commented out by default in this example file.

So the problem was how setting that option specifically works. It defines a new alias method and then undefs the original. So it defined an alias to client named client then undefed client. https://github.com/zipmark/rspec_api_documentation/blob/master/lib/rspec_api_documentation/configuration.rb#L98-L99

I'm not sure this is a problem because they're the defaults and you shouldn't have to copy any of them in order for the configuration to kick in. If you want to make a PR for the setter method skipping the module eval if the value didn't change I'd accept it.
