Question

当我运行rspec时，我收到此警告： -

DEPRECATION WARNING: Using positional arguments in functional tests has been deprecated,
in favor of keyword arguments, and will be removed in Rails 5.1.

Deprecated style:
get :show, { id: 1 }, nil, { notice: "This is a flash message" }

New keyword style:
get :show, params: { id: 1 }, flash: { notice: "This is a flash message" },
  session: nil # Can safely be omitted.
 (called from block (4 levels) in <top (required)> at /home/user/organization/fooobarr/spec/controllers/contacts_controller_spec.rb:13)

这是我的控制器规格： -

require 'rails_helper'

RSpec.describe ContactsController, :type => :controller do

  describe "#create" do
    it "sends an email when message is valid" do
      expect{
        post :create, message: attributes_for(:message)
      }.to change{ ActionMailer::Base.deliveries.count }.by(1)
    end

    it "does not send email when message is invalid" do
      expect{
        post :create, message: {subject: "", name: "",
                                email:"", content: ""}
      }.to change{ ActionMailer::Base.deliveries.count }.by(0)
    end
  end
end

在第13行和第19行引发错误。

我不确定如何更改我的代码，以便不再显示警告。

为了将来参考，您还可以使用Rubocop的Autofix功能修复这些（批量！）：

http://rubocop.readthedocs.io/en/latest/cops_rails/#railshttppositionalarguments

bundle exec rubocop --rails --only HttpPositionalArguments --auto-correct

请记住在Rubocop配置中设置TargetRailsVersion: 5.0或更高版本，以启用该警察。

好的，我得到了以下内容： -

  describe "#create" do
    it "sends an email when message is valid" do
      expect{
        post :create, params: {message: attributes_for(:message)}
      }.to change{ ActionMailer::Base.deliveries.count }.by(1)
    end

    it "does not send email when message is invalid" do
      expect{
        post :create, params: {message: {subject: "", name: "",
                                email:"", content: ""}}
      }.to change{ ActionMailer::Base.deliveries.count }.by(0)
    end
  end
end

感谢@samjewell的提示。看来这种语法现在已经过时了，我无法使用--rails参数。

这是今天实现这一目标的最新方法

在您的Gemfile中，使用gem 'rubocop-rails'代替rubocop。

在您的.rubocop.yml中添加require和相关的Rails版本

require: rubocop-rails
Rails:
  Enabled: true
AllCops:
   TargetRubyVersion: 2.4
   TargetRailsVersion: 5.0

然后运行

bundle exec rubocop --only Rails/HttpPositionalArguments -a

自动修复这些弃用警告

希望这对某人有帮助。

在功能测试中使用位置参数已被弃用
