features/cherry_pick.feature

+Feature: hub cherry-pick
+  Background:
+    Given I am in "git://github.com/rtomayko/ronn.git" git repo
+    And I am "mislav" on github.com with OAuth token "OTOKEN"
+
+  Scenario: Unchanged
+    When I run `hub cherry-pick a319d88`
+    Then the git command should be unchanged
+
+  Scenario: From GitHub commit URL
+    When I run `hub cherry-pick https://github.com/rtomayko/ronn/commit/a319d88#comments`
+    Then "git fetch origin" should be run
+    And "git cherry-pick a319d88" should be run
+
+  Scenario: From fork that has existing remote
+    Given the "mislav" remote has url "git@github.com:mislav/ronn.git"
+    When I run `hub cherry-pick https://github.com/mislav/ronn/commit/a319d88`
+    Then "git fetch mislav" should be run
+    And "git cherry-pick a319d88" should be run
+
+  Scenario: Using GitHub owner@SHA notation
+    Given the "mislav" remote has url "git@github.com:mislav/ronn.git"
+    When I run `hub cherry-pick mislav@a319d88`
+    Then "git fetch mislav" should be run
+    And "git cherry-pick a319d88" should be run
+
+  Scenario: Using GitHub owner@SHA notation that is too short
+    When I run `hub cherry-pick mislav@a319`
+    Then the git command should be unchanged
+
+  Scenario: Unsupported GitHub owner/repo@SHA notation
+    When I run `hub cherry-pick mislav/ronn@a319d88`
+    Then the git command should be unchanged
+
+  Scenario: Skips processing if `-m/--mainline` is specified
+    When I run `hub cherry-pick -m 42 mislav@a319d88`
+    Then the git command should be unchanged
+    When I run `hub cherry-pick --mainline 42 mislav@a319d88`
+    Then the git command should be unchanged
+
+  Scenario: Using GitHub owner@SHA notation with remote add
+    When I run `hub cherry-pick mislav@a319d88`
+    Then "git remote add -f mislav git://github.com/mislav/ronn.git" should be run
+    And "git cherry-pick a319d88" should be run
+
+  Scenario: From fork that doesn't have a remote
+    When I run `hub cherry-pick https://github.com/jingweno/ronn/commit/a319d88`
+    Then "git remote add -f jingweno git://github.com/jingweno/ronn.git" should be run
+    And "git cherry-pick a319d88" should be run
