 Feature: Applies Post-Parsing Rules
   As a source code writer I want to be sure that
   certain post-parsing rules are applied
 
-  Scenario: Throwing exception on invalid estimate
+  Scenario: Throwing exception on big estimates
     Given I have a "Sample.java" file with content:
     """
     @todo #13:180m This puzzle has too big estimate
     """
     When I run bin/pdd with "--rule=max-estimate:90"
     Then Exit code is not zero
     Then Stdout contains "bigger than 90 minutes"
 
-  Scenario: Throwing exception on invalid estimate
+  Scenario: Throwing exception on small estimates
     Given I have a "Sample.java" file with content:
     """
     @todo #13:15min This puzzle has too small estimate
     """
     When I run bin/pdd with "--rule=min-estimate:30"
     Then Exit code is not zero
     Then Stdout contains "lower than 30 minutes"
 
+  Scenario: Throwing exception on duplicates
+    Given I have a "Sample.java" file with content:
+    """
