280 CHAPTER 10 Tracking state
33 of features/creating_comments.feature, which should be the scenario title of
“Changing a ticket’s state”:
Given "user@ticketee.com" can change states on the "Ticketee" project
With the step in your scenario using this step definition now, the scenario will pass
when you rerun it using bin/cucumber features/creating_comments.feature:33:
1 scenario (1 passed)
16 steps (16 passed)
Good! All the scenarios in this feature should now be passing; you’ll check that in a
minute. Your next step was going to be to ensure that the state_id parameter wasn’t
passed through if the user doesn’t have access to create a state, but you’ve just added a
new permission to the system. You should ensure that this permission is assignable to
users before continuing, which you can do by adding a scenario to the Assigning Permissions
feature.
10.5.2 Bestowing changing state permissions
The features/assigning_permissions.feature file contains the Assigning Permissions feature,
which you’ve used to ensure that permissions are assignable from the permissions
page in the backend accessible by admins. Let’s add another scenario now to test
that you can assign this “change states” permission, as shown in the following listing.
Listing 10.29 features/assigning_permissions.feature
Scenario: Changing states for a ticket
When I check "View" for "TextMate 2"
And I check "Change States" for "TextMate 2"
And I press "Update"
And I follow "Sign out"
Given I am signed in as "user@ticketee.com"
When I follow "TextMate 2"
And I follow "Shiny!"
When I fill in "Text" with "Opening this ticket."
And I select "Open" from "State"
And I press "Create Comment"
Then I should see "Comment has been created."
And I should see "Open" within "#ticket .state"
When you run this scenario with the command bec features/assigning
_permissions.feature:73, you see that it can’t find the Change States select box for
the TextMate 2 project:
cannot check field, no checkbox ... 'permissions_1_change_states'
This is fine. You haven’t added it to the list of permissions inside of app/helpers/
admin/permissions_helper.rb yet. You can add this now by adding this key-value pair to
the Hash object in the permissions method’s hash:
"change states" => "Change States"
