+Feature: Check macros used with boost test driver
+
+  This is just a simple feature meant to test boost's 
+  specyfic validation macros interop with cucumber.
+
+  Scenario Outline: <check> macro
+    Given the following feature:
+      """
+      Feature: Feature name
+        Scenario: Scenario name
+          Given a step
+      """
