Abstract: For problems that current testing methods of performance of coal mine safety monitoring and control system cannot meet testing requirements under conditions of large data and concurrent operation of multi-users, a testing method of performance of coal mine safety monitoring and control system was proposed based on automatic testing tool LoadRunner. Testing processes were introduced in details including testing planning, testing script creating, scenario designing, scenario running and monitoring and testing result analyzing combined with specific implementation of concurrency testing and stability testing. The method can improve efficiency and accuracy of testing.
