尝试在Rspec 3中为模型存根链接的方法

Question

I am really new to Rspec and tried to find my answer, but it keeps on pointing me to use stub_chain, but it seems like it is deprecated on Rspec3. I have the following I am trying to stub:

active_automation = Client.automation_active_status.new_client

Where Client is my model and automation_active_status is the following in my Client model

scope :automation_active_status, -> { where(automation_status: true) }

new_client is an attribute I want to call to further filter my result

I tried to implement stub_chain but that did not work. My goal is to get the following to work:

Client.any_instance( black_box_I_can_not_figure_out ).returns[something]

Thank you.

Answer 1

I believe you might be looking for allow and receive_message_chain .

allow(Client).to receive_message_chain(:automation_active_status, :new_client) { [thing_to_return] }

This will stub the methods allowed it, and return whatever comes out of the block you pass it. Hope it helps.

Answer 2

Client.stub_chain(:automation_active_status, :new_client).and_return([thing-to-return]) should get you where you're trying to get.

Additionally, any_instance should be used on instances of a class. For instance, Client.first would be an instance, but Client is the class (and you can stub directly on it).
