Question

简化我的问题：

  it 'should call resolve', focus: true do
    SubscriptionEventResolver.any_instance.should_receive(:resolve)
    SubscriptionEventResolver.new(double().as_null_object).resolve
  end

此测试失败，并显示以下消息：

Failures:

  1) SubscriptionEvent should call resolve
     Failure/Error: SubscriptionEventResolver.any_instance.should_receive(:resolve)
       (#<Mocha::ClassMethods::AnyInstance:0x007f89c40a5488>).resolve(any args)

为什么？

（我正在使用rspec-rails（2.14.0）更新所有依赖项。）

Answer 1

这对我有用

require 'rspec/autorun'

class SubscriptionEventResolver < Struct.new(:event)
end

describe SubscriptionEventResolver do
  it 'should call resolve' do
    SubscriptionEventResolver.any_instance.should_receive(:resolve)
    SubscriptionEventResolver.new(double().as_null_object).resolve
  end
end

给了我

[17:40] arkham ~/Desktop [2.0.0-p247]
↳ $ ruby resolver_spec.rb
.

也许有其他事情在干扰？

Answer 2

您是否尝试过：

it 'should call resolve', focus: true do
  resolver = double('resolver')
  resolver.should_receive(:resolve)
  SubscriptionEventResolver.stub(:new).and_return(resolver)

  SubscriptionEventResolver.new(double('argument').as_null_object).resolve
end

一起使用any_instance和should_receive是行不通的
