查看rspec中的html属性测试

Question

使用rspec视图，我想测试html元素是否具有所需的属性集：

我有以下观点：

app/views/reset/new.html.erb

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

以及测试：

spec/views/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

我想在测试中结合这两个期望，这样我就可以检查元素email是否具有必需的属性。

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
