+Feature: JSON output
+  As a source code writer I want to be able to
+  call PDD as a command line tool, and retrieve an
+  JSON report
+
+  Scenario: JSON report building
+    Given I have a "Sample.java" file with content:
+    """
+    public class Main {
+      /**
+       * @todo #13 Let's do json
+       *  or maybe not json ":)"
+       */
+      public void main(String[] args) {
+        // later
+      }
+    }
+    """
+    When I run bin/pdd with "-v -s . -f out.json --format=json"
+    Then Exit code is zero
+    And Stdout contains "Reading from root dir ."
+    And Text File "out.json" contains "Let's do json or maybe not json “:)“"
