+Feature: Creating lists and tasks
+  In order to perform my tasks one by one
+  As a user
+  I want to have an ability to see a list of tasks for my day
+
+  Background:
+    Given there are users registered in system:
+    | email             | password    |
+    | adsam@example.com | my_password |
+    | john@example.com  | my_password |
+
+  Scenario: Creating list
+    Given I am signed in as "john@example.com" with password "password"
+    When I create new list "Work"
+    Then I can see list named "Work"
+    And I can't see any other list than list "Work"
+    And list "Work" has no tasks yet
+    When I create new task "Read emails" under "Work" list
+    When I create new task "Prepare Q1 report" under "Work" list
+    Then list "Work" has task "Read emails" assigned
+    And list "Work" has task "Prepare Q1 report" assigned
+    And task "Read emails" under list "Work" is not yet completed
+    And task "Prepare Q1 report" under list "Work" is not yet completed
+    When I mark task "Prepare Q1 report" under list "Work" as completed
+    And task "Prepare Q1 report" under list "Work" is completed
+    But task "Read emails" under list "Work" is not yet completed
