Aiming at the problems of low quality, long cycle and low efficiency in the manual CBTC system testing, an automated testing method based on Robot Framework was proposed in this paper. Taking the temporary speed restriction initialization scenario as an example, the entire process from scenario requirement analysis, test case generation, test case execution and test report generation was analyzed and verified. The results showed that the automated testing system based on Robot Framework could be used for the testing of the CBTC system, which could effectively improve the testing efficiency about 10 times and the missing rate of the problem was reduced to 0.08%. Therefore, automated testing can shorten the development cycle, and save a lot of manpower and material resources.
