Embodiment 1

[0046]As the core of the automated test platform, the test engine is responsible for the analysis and execution of the test script and the determination of the results. It drives the STP simulation test platform to complete the specified actions required for the test, and records the test data for analysis. During the test process, the manual intervention test process provides support.

[0047] The automatic test engine of the present invention includes two parts: a test main engine and a test sub-engine. The main test engine is the central control unit, which provides analysis of test scripts, control of test processes, distribution of test tasks, synchronization and coordination of each test executor, collection of subscribed test data from test sub-engines, termination of test scripts, Functions such as pause, reload and cancel and resume of test actions. The test sub-engine (that is, the distributed test executor) is the real executor of the test script. It no longer has ...

Abstract

The invention belongs to the technical field of train control, and relates to an engine for automatic testing of a CBTC system, which comprises a testing main engine and a testing sub-engine, whereinthe test main engine is used for providing analysis of test scripts, control of a test process, distribution of test tasks, synchronization and coordination of all test actuators, collection of subscribed test data from the test sub-engines, and termination, pause and reloading of the test scripts and cancellation and recovery of test actions for the central control unit; and the test sub-enginesare real executors of the test scripts, sequentially send messages to the STP simulation test platform according to the test actions issued by the main engine, and receive the messages uploaded by theSTP simulation test platform. The automatic test engine can be deployed in a distributed manner, and test cases can be executed concurrently. The application layers of the test sub-engines are integrated and realized by related modules of the STP simulation platform, so that the test sub-engines can be distributed on different machines for parallel execution with extremely low expenditure, and the test execution efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of train control, and in particular relates to an engine used for automatic testing of a CBTC system. Background technique [0002] With the rapid development of computer technology and communication technology, communication-based train control technology CBTC (Communication Based Train Control) has developed into the mainstream signal system in urban rail transit. At present, the scale of CBTC system products is getting larger and larger, and the complexity of its business and implementation is also getting higher and higher. Such large-scale and high-complexity control software has brought great troubles to the testing work, and traditional manual testing is error-prone, low-efficiency, and high-cost, so software automated testing is imperative. [0003] 1. Introduction to automated testing methods [0004] Commonly used automated testing methods mainly include simple recording / playback, data-driven and...
