我在我的应用程序中使用设计，并尝试编写更新电子邮件 ID 的规范。用户界面有效，但规范失败。在针对更改的电子邮件 ID 进行测试之前，我也在重新加载用户对象。

我确实观察到的一件事是数据库上正在运行 UPDATE USERS 语句。

编写规范的正确方法是什么？

RSpec 规格：

it "should update email" do
  @user = subject.current_user
  patch :update, id: @user, user: {:email => "john.doe@example1.com"}
  @user.reload
  expect(@user.email).to eq("john.doe@example1.com")
end

RSpec 错误日志：

1) Users::RegistrationsController logged in user should update email
   Failure/Error: expect(@user.email).to eq("john.doe@example1.com")

   expected: "john.doe@example1.com"
        got: "john.doe@example.com"

   (compared using ==)

尝试

it "should update email" do
  @user = subject.current_user
  patch :update, id: @user, user: {:email => "john.doe@example1.com"}
  @user.reload.email.should == "john.doe@example1.com"
end

或者，

it "should update email" do
  @user = subject.current_user
  expect {
    patch :update, id: @user, user: {:email => "john.doe@example1.com"}
    @user.reload
  }.to change(@user, :email).to("john.doe@example1.com")
end
