+Feature: Reek reads from $stdin when no files are given
+  In order to use reek with pipelines
+  As a developer
+  I want to pipe source code on stdin
+
+  Scenario: return zero status with no smells
+    When I pass "def simple() @fred = 3 end" to reek
+    Then it succeeds
+
+  Scenario: outputs nothing on empty stdin
+    When I pass "" to reek
+    Then it succeeds
+    And stdout equals ""
+
+  Scenario: return non-zero status when there are smells
+    When I pass "def x() 3; end" to reek
+    Then it fails with exit status 2
+
+  Scenario: output nothing when no smells
+    When I pass "def simple() @fred = 3; end" to reek
+    Then it succeeds
+    And stdout equals ""
+
+  Scenario: report smells correctly
+    When I pass "class Turn; def y() @x = 3; end end" to reek
+    Then it fails with exit status 2
+    And it reports:
+      """
+        Turn has the variable name '@x' (Uncommunicative Name)
+        Turn#y has the name 'y' (Uncommunicative Name)
+
