我试图用rspec来模拟一个类的方法：
LIB / db.rb
class Db
def self.list(options)
Db::Payload.list(options)
end
end
LIB /分贝/ payload.rb
class Db::Payload
def self.list(options={})
end
end
在我的规格中,我试图设置期望当调用Db.list时,Db :: Payload.list将被调用：
require 'db/payload'
describe Db do
before(:each) do
@options = {}
Db::Payload.should_receive(:list).with(@options)
end
it 'should build the LIST payload' do
Db.list(@options)
end
end
问题是我总是收到以下错误：
undefined method `should_receive' for Db::Payload:Class
任何帮助了解这个错误将是最感激的:-)
解决方法
你的spec_helper.rb应该有这样的东西：
Spec::Runner.configure do |config| # == Mock Framework # # RSpec uses its own mocking framework by default. If you prefer to # use mocha,flexmock or RR,uncomment the appropriate line: # # config.mock_with :mocha # config.mock_with :flexmock # config.mock_with :rr end
默认参数是config.mock_with：rspec,它启用了should_receive方法.例如,如果您使用摩卡车,相当于预期,所以请确保使用正确的嘲笑框架.
