查看 rspec 中 html 属性的测试

Question

使用RSPEC视图，我想测试HTML元素具有所需的属性集：

我有以下视图：

app/views/reset/new.html.erb

<%= text_field_tag :email, params[:email], required: true %>

和测试：

spec/views/reset/reset/reset_spec。 RB

RSpec.describe "authentications/reset/new" do

require "rails_helper"

RSpec.describe "authentications/reset/new" do
    it "email is required" do
     render
     expect(rendered).to have_selector("#email")
     expect(rendered).to have_xpath("//input[@required='required']")
  end
end

我想在测试中将两个期望结合起来，以便我可以检查元素电子邮件是否具有所需的属性。

Answer 1

require "rails_helper"

RSpec.describe "authentications/reset/new" do
  # use specify when "it" doesn't make grammatical sense
  specify "email is required" do
     expect(rendered).to have_selector('input[type="email"][required]')
  end
end
