Why is this rspec test throwing a "undefined method `call' for nil:NilClass" error?

rspec, ruby

Solution

To get your bare application registered you'll need to set the app to the Sinatra::Application:

specApiDocumentation.configure do |config|
#  config.app = App 
end

To:

specApiDocumentation.configure do |config|
   config.app = Sinatra::Application
end

Problem

I'm trying to integrate rspec_api_documentation (https://github.com/zipmark/rspec_api_documentation) into my sinatra app. I'm running into the error below. I've obviously simplified the error down to a bare test, because I think once I figure out what is wrong in the configuration, it'll work once reintegrated into my larger app. Thanks! In app.rb: ``` require 'rubygems' require 'sinatra' get '/index' do "hewoah!" end ``` In spec.rb: ``` require "rspec_api_documentation" require "rspec_api_documentation/dsl" RspecApiDocumentation.configure do |config| # config.app = App end resource "Users" do get "/index" do example "Returns text" do do_request status.should be_ok end end end ``` Results of `rspec spec/acceptance/spec.rb --require ./app.rb` F ``` Failures: 1) Users GET /index Returns text Failure/Error: do_request NoMethodError: undefined method `call' for nil:NilClass # ./spec/acceptance/spec.rb:11:in `block (3 levels) in <top (required)>' Finished in 0.02234 seconds 1 example, 1 failure Failed examples: rspec ./spec/acceptance/spec.rb:10 # Users GET /index Returns text ```
