+Feature: Check for minimum or maximimum version of Moodle
+    In order adapt acceptance tests for different versions of Moodle
+    As a developer
+    I should be able to skip tests according to the Moodle version present on a site
+
+  Scenario: Minimum version too low
+    Given the site is running Moodle version 99.0 or higher
+    # The following steps should not be executed. If they are, the test will fail.
+    When I log in as "admin"
+    Then I should not see "Home"
+
+  Scenario: Maximum version too high
+    Given the site is running Moodle version 3.0 or lower
+    # The following steps should not be executed. If they are, the test will fail.
+    When I log in as "admin"
+    Then I should not see "Home"
+
+  Scenario: Minimum version OK
+    Given the site is running Moodle version 3.0 or higher
+    When I log in as "admin"
+    Then I should see "Home"
+
+  Scenario: Maximum version OK
+    Given the site is running Moodle version 99.0 or lower
+    When I log in as "admin"
+    Then I should see "Home"
