Question

I’m trying to use Capybara to test that a list contains the correct items. For example:

<table id="rodents">
  <tr><td class="rodent_id">1</td><td class="rodent_name">Hamster</td></tr>
  <tr><td class="rodent_id">2</td><td class="rodent_name">Gerbil</td></tr>
</table>

This list should contain ids 1 and 2, but should not include 3.

What I’d like is something like:

ids = ? # get the contents of each row's first cell
ids.should include(1)
ids.should include(2)
ids.should_not include(3)

How might I do something like that?

I’m answering with a couple of unsatisfactory solutions I’ve found, but I’d love to see a better one.

Answer 1

Here is a slightly simplified expression:

  rodent_ids = page.all('table#rodents td.rodent_id').map(&:text)

From there, you can do your comparisons.

  rodent_ids.should include(1)
  rodent_ids.should include(2)
  rodent_ids.should_not include(3)
