RSpec 应该接收 class 的实例对象

Question

请告诉我如何检查 should_receive 中返回的对象是否是 ClassName 的实例。

Messaging.should_receive(:send_text).with(:foo, :bar, object)

Rails 3

Answer 1

答案是： Messaging.should_receive(:send_text).with(:foo, :bar, kind_of(ClassName))

编辑：正确答案是：

Messaging.should_receive(:send_text).with(:foo, :bar, instance_of(ClassName))

Answer 2

如果你想让它接收一个特定的class的实例，那么可以使用instance_of:

Messaging.should_receive(:send_text).with(:foo, :bar, instance_of(ClassName))

RSpec should receive instance object of class
