Capybara issue when trying to click form submit button - ruby-on-rails

Question

I'm pretty new to Ruby/Rails and especially to Capybara and the whole process, so please bear with me as I've spent a lot of time on this already and I finally decided to ask because I'm sure it's something simple that I just am as-of-yet unaware of.
So I have a form that has several checkboxes that are designed to filter the results displayed (ie, you select one or more and submit and thew page reloads with the list filtered). In my features file, I have the following scenarios (the button to submit the form has a value="Refresh"):
Scenario: no ratings selected
When I uncheck the following ratings: G, PG, PG-13, NC-17, R
And I press "Refresh"
Then show me the page
And I should see none of the movies
Scenario: all ratings selected
When I check the following ratings: G, PG, PG-13, NC-17, R
And I press "Refresh"
Then show me the page
And I should see all of the movies
When I run this with rake features, it gives the following output:
And I press "Refresh" # features/step_definitions/web_steps.rb:61
xprop: unable to open display ''
I am using page.body a little later in the scenario and I believe this is the reason I then get the following errors:
Deprecated: please use #source_tags instead.

Here are the relevant step definitions
When /I (un)?check the following ratings: (.*)/ do |unc, rating_list|
rating_list.split(", ").each do |r|
if(unc)
uncheck("ratings_#{r}")
else
check("ratings_#{r}")
end
end
assert true, "Implemented checking function"
end
Then /I should (not )?see movies with the following ratings: (.*)/ do |nt, rating_list|
flag = true
rating_list.split(", ").each do |r|
if(nt)
if(page.body =~ /<td>#{r}/)
flag = false;
end
else
if(page.body !~ /<td>#{r}/)
flag = false
end
end
end
assert flag, "Seeing (or not) movies of ratings list - implemented"
end
Then /I should see all of the movies/ do
tot = Movie.all.count
assert page.have_selector('tbody tr', :count => tot)
end
Then /I should see none of the movies/ do
num = page.body.scan(/00:00:00 UTC/m).length
assert size == 0, "Showing no movies - implemented"
end
When /^(?:|I )press "([^"]*)"$/ do |button|
click_button(button)
end
Then /^show me the page$/ do
save_and_open_page
end
I have been researching for days when I have time and there is just so much I don't know. Any help or insights would be greatly appreciated. Thank you!

Answer 1

Your problem is that you don't have any browser installed to handle html files.
It seems you are using an headless server (without X) so your system is trying to find a suitable browser (one that can be run from the command line).
Take a look at Capybara drivers and choose an appropriate one.
