+Feature: Coverage Of
+  In order to find out how well tested a source file that I'm working on is
+  As a developer
+  I want to be able to ask Cucover which features cover which lines of a given source file
+
+  Background:
+    Given the cache is clear
+    And I am using the simple example app
+    And I have run cucover -- features/call_foo.feature
+
+  Scenario: Run a feature that covers only some of the source code in a file
+    When I run cucover --coverage-of lib/foo.rb
+    Then it should pass with:
+    """
+    1 features/call_foo.feature class Foo
+    2 features/call_foo.feature   def execute
+    3 features/call_foo.feature     true
