11.4.1 Testing tag deletion
To click this link using Cucumber, you give the link around the X an id so you can easily
locate it in your feature, which you’ll now write. Let’s create a new file at features/
deleting_tags.feature and put in it the code from the following listing.
Listing 11.3 features/deleting_tags.feature
Feature: Deleting tags
In order to remove old tags
As a user
I want to click a button and make them go away
Background:
Given there are the following users:
| email | password |
| user@ticketee.com | password |
And I am signed in as them
And there is a project called "Ticketee"
And "user@ticketee.com" can view the "Ticketee" project
And "user@ticketee.com" can tag the "Ticketee" project
And "user@ticketee.com" has created a ticket for this project:
| title | description | tags |
| A tag | Tagging a ticket! | this-tag-must-die |
Given I am on the homepage
When I follow "Ticketee" within "#projects"
And I follow "A tag"
@javascript
Scenario: Deleting a tag
When I follow "delete-this-tag-must-die"
Then I should not see "this-tag-must-die"
In this scenario, it’s important to note that you’re passing through the tags field as a
field in the “created a ticket” step, just like the other fields. The tags field isn’t in the
tickets table. You’ll get to that in a second.
In this feature, you create a new user and sign in as them. Then you create a new
project called Ticketee and give the user the ability to view and tag the project. You
create a ticket by the user and tag it with a tag called this_tag_must_die. Finally, you
navigate to the page of the ticket you’ve created.
In the scenario, you follow the delete-this-tag-must-die link, which will be the
id on the link to delete this tag. When this link has been followed, you shouldn’t see
this_tag_must_die, meaning that the action to remove the tag from the ticket has
worked its magic.
When you run this feature using bin/features/deleting_tags.feature, you get
this error:
undefined method `each' for "this_tag_must_die":String (NoMethodError)
