如何在 Rails 5 的 RSpec 中期待 Params 哈希？

Question

我正在升级到 Rails 5，即使我传递了我应该传递的数据，它也破坏了我的 RSpec。

问题明显出在这里：

expected: ({"name"=>"MyString"})
got: (<ActionController::Parameters {"name"=>"MyString"} permitted: true>)

这意味着我需要能够修复我的控制器断言，以便它期待后者。这是需要改变的路线。

expect_any_instance_of(Hospital).to receive(:update).with({ "name" => "MyString" })

大概是这样的

expect_any_instance_of(Hospital).to receive(:update).with(params: { "name" => "MyString" }, permitted: true)

我只是不知道语法是什么，并且在 Rails 5 的零散文档中的任何地方都找不到它，或者关于 Rails 5 上的 RSpec 的不存在的注释/堆栈溢出问题。

    it "updates the requested hospital" do
      hospital = Hospital.create! valid_attributes
      # Assuming there are no other hospitals in the database, this
      # specifies that the Hospital created on the previous line

      # submitted in the request.
      expect_any_instance_of(Hospital).to receive(:update).with({ "name" => "MyString" })
      put :update, {:id => hospital.to_param, :hospital => { "name" => "MyString" }}, valid_session

    it "assigns the requested hospital as @hospital" do
      hospital = Hospital.create! valid_attributes
      put :update, {:id => hospital.to_param, :hospital => valid_attributes}, valid_session
      expect(assigns(:hospital)).to eq(hospital)
    end

    it "redirects to the hospital" do
      hospital = Hospital.create! valid_attributes

    end
  end

您是否尝试过仅使用 ActionController::Parameters 对象作为您期望的值？

如：

expect_any_instance_of(Hospital).to receive(:update).with(ActionController::Parameters.new('name':'MyString'))
