Cucumber: selecting an element from a table for de

Question

I have the following table in an application I am developing using ruby on rails:

I want to create a test in cucumber where I select a user from the table and delete it or edit it.

I don't know what is the step definition for that.

I'd like to be able to do something like:

Feature: User Manegement
         In order to manage users
         As an admin 
         I want to see a users list and change user properties

Background:
Given the following activated users exists
  | name         | email                    | 
  | Alice Hunter | [e-mail] |
  | Bob Hunter   | [e-mail]   |
And the following user records
  | name     | email                    | 
  | Jonh Doe | [e-mail]     |

    Scenario: I delete a user from the table
      Given I am logged in as admin
      When I follow "Administration"
      And I follow "User Management"
      And I delete "Alice Hunter"
      Then I should not see "Alice Hunter"`

Can anyone help? Thank you.

Answer 1

After some extensive searching and minor refactoring, I managed to solve the problem.

I have used the following step:

When /^as admin I (press|follow|check|uncheck|choose) "([^\"]*)" for (.*) whose (.*) is "([^\"]*)"$/ do |action, whatyouclick, class_name, var_name, value|
  unless var_name == "id" then
    id = eval("\"#{class_name}\".classify.constantize.find_by_#{var_name}(\"#{value}\").id.to_s")
  else
    id = value
  end
  within("tr[id=as_admin__#{class_name}-list-#{id}-row]") do
    case action
      when "press"
        click_button(whatyouclick)
      when "follow"
        click_link(whatyouclick)
      when "check"
        check(whatyouclick)
      when "uncheck"
        uncheck(whatyouclick)
      when "choose"
        uncheck(whatyouclick)
    end
  end
end

I am also insterested in webrat's RDoc, but everything I find seems out of order.

Answer 2

I have a bit of a legacy app that isn't being nice with regard to useful link ids or even classes (i.e. class="deleteLink"). I have to find the link that has 'delete' in the href. Obviously this is error prone but it's working for now. Here's the code for that.

When /^I delete "([^"]*)"$/i do |value|
  page.evaluate_script('window.confirm = function() { return true; }') 
  within(:xpath, "//tr[.//*[contains(text(), '#{value}')]]") do
    find(:xpath, ".//a[contains(@href,'delete')]").click
  end
end

It's a little messy in the xpath, but it's what i could finally get to work. I'm using Cucumber/Rspec/Capybara/Selenium to test a Java app BTW.

Answer 3

Following on Brad's answer below I went with:

When /^I follow "([^"]*)" for "([^"]*)"$/ do |link, person|
  # Use capybara to find row based on 'person' text... no need for the additional 'find'
  # the '.,' sets the scope to the current node, that is the tr in question
  within(:xpath, "//table/tr[contains(.,'#{person}')]") do
    click_link(link)
  end
end

Answer 4

I'm going to assume it's the deleting part that is messing you up as the other stuff is fairly standard (setting up givens and following links etc...)

So, what are you using as your browser abstraction? Webrat? Capybara? It appears as if you have a 'delete' link, is it sufficient to do something like this?

And /I delete "(.*)"/ do |person|
  # Use webrat or capybara to find row based on 'person' text... then find 'delete' link in row and click it
  # example (untested, pseudo code)
  within(:xpath, "//table/tr[contains(#{person})") do
    find('.deleteLink').click
  end
end

And I believe something like "should not see" is probably supported out of the box with generated webrat/capybara steps.

Is this what you're looking for?

Answer 5

I had the same problem, and looking into the translation of 'I follow "abcd"' to click_link(), I found there's an optional :method. So I defined this:

When /^(?:|I )follow "([^"]*)" as delete$/ do |link|
  click_link(link, :method => :delete)
end

and that worked... Then I decided to make it more general, not just "as delete":

When /^(?:|I )follow "([^"]*)" as ([a-z]+)$/ do |link,method|
  click_link(link, :method => method.to_sym)
end

Works great. I tried it with 'I follow "mylink" as get' too, and that worked, so the method part seems to be suitably flexible.
