Question

尝试设置capybara / rspec来测试一个简单的sinatra应用程序，但不断出现机架错误。

hello.rb的

require 'sinatra'

class App < Sinatra::Base
  get "/" do
    "hello hello!"
  end

  run! if app_file == $0
end

规格/ hello_spec.rb

require File.join(File.dirname(__FILE__), '..', 'hello.rb')

require 'rspec'
require 'capybara'
require 'capybara/dsl'
require 'capybara/rspec'

set :environment, :test

describe 'The Hello App' do

  include Capybara::DSL
  def setup
    Capybara.app = App
  end

  it "says hello when browsing /" do
    visit '/'
    page.should have_content('hello')
  end
end

注意，我也试过

  def setup
    Capybara.app = App.new
  end

产生了同样的错误。

错误：

C:\Sites\misc\qrgen>bundle exec rspec
F

Failures:

  1) The Hello App says hello when browsing /
     Failure/Error: visit '/'
     ArgumentError:
       rack-test requires a rack application, but none was given
     # ./spec/hello_spec.rb:18:in `block (2 levels) in <top (required)>'

Finished in 0.374 seconds
1 example, 1 failure

Failed examples:

rspec ./spec/hello_spec.rb:17 # The Hello App says hello when browsing /

使用和不使用bundle exec运行相同的错误。有什么想法吗？

Gemfile：

gem "sinatra"
gem "sinatra-contrib"
gem "sinatra-flash"
gem "slim"

gem "rspec"
gem "capybara"
gem "rack-test"

Answer 1

希望这对尝试从Sinatra文档设置测试的其他人有用。

更改

def setup
  Capybara.app = App
end

到

Capybara.app = App

解决了这个问题。

与capybara / sinatra测试的机架错误...似乎没有传递Sinatra应用程序
