+Feature: Bulk Vehicle Inspection API
+  This feature tests the bulk vehicle inspection API endpoint.
+  It ensures that a batch of vehicle inspections can be submitted successfully,
+  all required IDs are valid, and the API responds within an acceptable time frame.
+
+  @sunny_day @fast_response
+  Scenario: Successfully submit vehicle inspections in bulk within time limit
+    When I send a POST request to "/api/inspections?updateStrategy=INSERT&futz=true" with the payload from "test-data/vehicle-inspections.zip"
+    Then the response status code should be 200
+    And the response time should be under 5000 milliseconds
