+Feature: Creating BOM using Json format
+
+  Scenario: Running against simple fixture
+    Given I use a fixture named "simple"
+    And I run `cyclonedx-ruby --path . --format json`
+    Then the output should contain:
+    """
+    5 gems were written to BOM located at ./bom.json
+    """
+    And a file named "bom.json" should exist
+    And the generated XML Json file "bom.json" matches "bom.json.expected"
