如何解决RSpec关于新的Expect语法的弃用警告？ [英] How to resolve RSpec's deprecation warning about the new expect syntax?

问题描述

当我运行此RSpec示例时，它通过了，但是我收到了弃用警告。

When I run this RSpec example, it passes but I'm getting a deprecation warning.

context "should have valid detail for signup" do
  it "should give error for invalid confirm password" do
    find("#usernamesignup").set("Any_name")
    find("#mobile_number").set("1234567890")
    find("#emailsignup").set("[e-mail]")
    find("#passwordsignup").set("12345678")
    find("#passwordsignup_confirm").set("")
    find(".signin").click
    sleep 2
    page.should have_content "Confirm Password Does not Match"
  end
end

这是输出：

弃用警告：

从rspec-expectations中使用应该不推荐使用不带
的旧：应该语法。使用新的：expect
语法，或使用 config显式启用：should 。 Expect_with（：rspec）
{| c | c.syntax =：should} 。从
/home/rails/rails_nimish/Devise_use/spec/features/users_spec.rb:113：在
`block（4个级别）'

Using should from rspec-expectations' old :should syntax without explicitly enabling the syntax is deprecated. Use the new :expect syntax or explicitly enable :should with config.expect_with(:rspec) { |c| c.syntax = :should } instead. Called from /home/rails/rails_nimish/Devise_use/spec/features/users_spec.rb:113:in `block (4 levels) in '

中调用

如何解决此警告？

更新：解决方案
我刚刚替换了

Update:solution I just replaced

页面。 have_content确认密码不匹配

page.should have_content "Confirm Password Does not Match"

with：

expect(page).to have_content "Confirm Password Does not Match"

推荐答案

如消息所示，您有两个选择：

As the message says you have two options:

• 将RSpec显式配置为允许。应该。不要使用该选项； 。应该已过时，将来可能不会得到很好的支持。但是，如果您确实想允许。应该，则可以通过将其添加到spec_helper.rb中（或编辑可能已经存在的rspec-mocks的示例配置）来实现。在那里）：

• Explicitly configure RSpec to allow .should. Don't use that option; .should is deprecated and will likely not be as well supported in the future. If you really wanted to allow .should, though, you could do it by adding this to your spec_helper.rb (or editing the example configuration of rspec-mocks that is probably already there):

RSpec.configure do |config|
  config.expect_with :rspec do |expectations|
    expectations.syntax = :should
  end
end

如果您想同时使用期望和。应该，设置

If you want to use both expect and .should, set

expectations.syntax = [:expect, :should]

但是不要那样做，选择一个并在测试套件中的任何地方使用它。

But don't do that, pick one and use it everywhere in your tests suite.

将您的期望重写为

expect(page).to have_content "Confirm Password Does not Match"

如果您有许多需要升级其语法的规范，则可以使用 transpec宝石>自动执行。

If you have many specs whose syntax needs upgrading, you can use the transpec gem to do it automatically.

侧面说明：请勿睡眠2 超出您的期望。 水豚属植物的 have_content 匹配器正等着您。

Side note: Don't sleep 2 before your expectation. Capybara's have_content matcher waits for you.
