What is Rspec | should_receive doing?

2019/04/16に公開

should_receive verifies that a method of a certain class is called.

I expect SomeModel.create to be called.

 it do SomeModel.should_receive(:create) SomeModel.create end

As an example, we call SomeModel.create right after here.

For example, in other methods. In the processing of the controller etc. It will succeed if SomeModel.create is called from anywhere or once.

It does not make sense to execute a method before should_receive.

 it do SomeModel.create SomeModel.should_receive(:create) end

.with

.with verifies that the method is called with specific arguments.

 it do SomeModel.should_receive(:create).with)(title: 'Bible') SomeModel.create(title: 'Bible') end

 it do SomeModel.should_receive(:create).with)(title: 'Bible') SomeModel.create(title: 'Gone with the wind') end

Since should is old, newer versions should use expect. http://qiita.com/shuhei/items/58452ad1572b7e40c150
