+    When user logs in with username "demo@demo.demo" and password "demo" using the webUI
+    Then the user should be in dashboard page
+
+
+  Scenario Outline: login with invalid username and invalid password
+    Given user has browsed to the login page
+    When user logs in with username "<username>" and password "<password>" using the webUI
+    Then user should see the error message "<message>"
+    Examples:
+      | username  | password | message                    |
