Rspec / rails：如何在视图中测试样本（x）

Question

I have a home page that is pulling random entries from my db using this code (probably not the best way, but it works)

def home
  ids = Entry.pluck(:id)
  @random_entries = Entry.find(ids.sample(5))
end

Here is the view:

<p>Here are 5 random entries:</p>
<% @random_entries.each do |entry| %>
<h3><%= entry.word.capitalize %></h3>
<p>Definition: <%= entry.definition %></p>
<% end %>

and so far my test is just:

it "should have the content 'Here are 5 random entries'" do
  visit '/'
  expect(page).to have_content('Here are 5 random entries')
end

But that test only checks for content that was hard-coded into the view. The controller/view are working as I want them, but I have no test and not quite sure where to begin writing one for this.

How should I be testing that controller action?

Answer 1

Maybe you could count the number of h3 tags that are present in the page like this:

page.all('h3').count.should eql(5)

That will do if you don't have any other h3 tags anywhere else in that view.
