+Feature: avatar
+
+  Background:
+    Given user "user0" exists
+
+  Scenario: get default user avatar
+    When user "user0" gets avatar for user "user0"
+    Then The following headers should be set
+      | Content-Type | image/png |
+      | X-NC-IsCustomAvatar | 0 |
+    And last avatar is a square of size 128
+    And last avatar is not a single color
+
+  Scenario: get default user avatar as an anonymous user
+    When user "anonymous" gets avatar for user "user0"
+    Then The following headers should be set
+      | Content-Type | image/png |
+      | X-NC-IsCustomAvatar | 0 |
+    And last avatar is a square of size 128
+    And last avatar is not a single color
+
+
+
+  Scenario: get temporary user avatar before cropping it
+    Given Logging in using web as "user0"
+    And logged in user posts temporary avatar from file "data/green-square-256.png"
+    When logged in user gets temporary avatar
+    Then The following headers should be set
+      | Content-Type | image/png |
+    # "last avatar" also includes the last temporary avatar
+    And last avatar is a square of size 256
+    And last avatar is a single "#00FF00" color

+  Scenario: get user avatar before cropping it
+    Given Logging in using web as "user0"
+    And logged in user posts temporary avatar from file "data/green-square-256.png"
+    # Avatar needs to be cropped to finish setting it even if it is squared
+    When user "user0" gets avatar for user "user0"
