ruby-on-rails - rspec 允许 where(id : my_id). 首先

Question

我正在 rspec 上编写测试，需要为 Location 模型允许以下行:

Location.where(id: params[:id]).first

但这是不正确的(两个参数而不是一个错误):

allow(Location).to receive(:where, :first).with(id: my_id)

这也是:

allow(Location).to receive(:where).with(id: my_id).first

哪种方法才是正确的做法？

Answer 1

你可以这样做:

allow(Location).to receive(:where).with(id: my_id).and_return double(first: <your Location mock here>)
