两个超级实用的 rspec matcher: include

refer to: http://stackoverflow.com/questions/9912315/should-not-include

说来惭愧,之前一直希望有个 should include('x') 这样的rspec 语法.结果今天才用到. 

  it 'should post login_validate' do
    post  :login_validate, :email => @user.email, :password => @user.password
    response.body.should include('id')
  end 

  it 'should get get_user_with_token' do
    get :get_user_with_token, :token => @user.token
    response.body.should_not include('invalid')
  end 

而且 describe 用的好的话, 很多参数可以省略: 

describe [1, 3, 7] do
  it { should include(1) }
  it { should include(3) }
  it { should include(7) }
  it { should include(1, 7) }
  it { should include(1, 3, 7) }
  it { should_not include(17) }
  it { should_not include(43, 100) }

  # deliberate failures
  it { should include(4) }
  it { should_not include(1) }
  it { should_not include(3) }
  it { should_not include(7) }
  it { should_not include(1, 3, 7) }

  # both of these should fail since it includes 1 but not 9
  it { should include(1, 9) }
  it { should_not include(1, 9) }
end
