Scenario based testing is a test methodology widely used in integration test and trial operation of urban transport. By setting a scenario which reflects a particular status of urban transport in normal, degraded, or emergency operations, a scenario test is used to demonstrate the function performance of certain systems involved so as to verify if the function performance can meet the operation requirements. With the engineering implementation of scenario tests in Mecca Light Rail, this paper provides an in-depth study about scenario test design with modelling works. A serial of models like the interface matrix, the function flow diagram, and the test flow diagram are used to determine all key elements of a scenario. Test scenarios designed in this way can be qualified to meet the integration, typicality and completeness requirements and implemented for overall metro system function verification. Keywords: scenario testing, systems integration test, Mecca light rail. 1 Introduction 1.1 Scenario testing in systems integration test Urban transport is a macro system consisting of a large number of equipments and facilities. Each individual system assumes various design functions with the availability of complex interfaces among them. In order to verify the overall performance of a new urban transport line before it is put to passenger operation, a systematic, multi-disciplinary, and integrated testing and commissioning (called Systems Integration Tests or Comprehensive Tests [1-3]) is needed to be deployed. Following the completion of various equipment systems'
