features/project/forked_merge_requests.feature

-Feature: Project Forked Merge Requests
-  Background:
-    Given I sign in as a user
-    And I am a member of project "Shop"
-    And I have a project forked off of "Shop" called "Forked Shop"
-
-  @javascript
-  Scenario: I submit new unassigned merge request to a forked project
-    Given I visit project "Forked Shop" merge requests page
-    And I click link "New Merge Request"
-    And I fill out a "Merge Request On Forked Project" merge request
-    And I submit the merge request
-    Then I should see merge request "Merge Request On Forked Project"
-
-  # TODO: Improve it so it does not fail randomly
-  #
-  #@javascript
-  #Scenario: I can edit a forked merge request
-    #Given I visit project "Forked Shop" merge requests page
-    #And I click link "New Merge Request"
-    #And I fill out a "Merge Request On Forked Project" merge request
-    #And I submit the merge request
-    #And I should see merge request "Merge Request On Forked Project"
-    #And I click link edit "Merge Request On Forked Project"
-    #Then I see the edit page prefilled for "Merge Request On Forked Project"
-    #And I update the merge request title
-    #And I save the merge request
-    #Then I should see the edited merge request
-
-  Scenario: I cannot submit an invalid merge request
-    Given I visit project "Forked Shop" merge requests page
-    And I click link "New Merge Request"
-    And I fill out an invalid "Merge Request On Forked Project" merge request
-    Then I should see validation errors
-
-  @javascript
-  Scenario: Merge request should target fork repository by default
-    Given I visit project "Forked Shop" merge requests page
-    And I click link "New Merge Request"
-    Then the target repository should be the original repository
-
-  @javascript
-  Scenario: I see the users in the target project for a new merge request
-    Given I sign in as an admin
-    And I have a project forked off of "Shop" called "Forked Shop"
-    Then I visit project "Forked Shop" merge requests page
-    And I click link "New Merge Request"
-    And I fill out a "Merge Request On Forked Project" merge request
-    When I click "Assign to" dropdown"
-    Then I should see the target project ID in the input selector
-    And I should see the users from the target project ID
