Problems solved by technology
In addition, the application of customized testing methods to the testing of network application layer software in different projects will result in waste of resources, huge costs, and low efficiency.
[0004] The existing network application layer software automation test system needs to develop a dedicated communication board or industrial computer to access the network system under test. Although it can be reused, the number of test items that can be performed at the same time is limited by the number of communication boards or industrial computers. Constraints, and there are hardware procurement costs
In addition, the existing network application layer control software has a large amount of network data, and the communication protocols between different projects cannot be reused; due to the dependence on various communication protocols, various conversion programs and test scripts cannot be reused of
The above problems point out the shortcomings of the existing automated testing system, that is, it requires huge resources and costs, and the input workload is not less than the workload of the system under test, resulting in low testing efficiency

test conclusion
TC-0393
"Traction valid"="1"
"Traction mode" is "high level"
TC-0394
TC-0393
"Traction Gathering Speed" is equal to "230"
"Train speed" is greater than "200"
[0049] In the TC-0393 use case, the automated test system is required to force the value of the variable "traction effective" to 1 and input it into the system under test, and observe whether the value of the variable "traction working condition" output by the system under test is equal to 1; while in TC- In 0394, the input / operation steps in the TC-0393 use case need to be executed first (the value of the variable "traction effective" is forced to 1 and input into the system under test), and then the variable "traction acquisition speed" is forced to 230 and input into The system under test, a...

The invention discloses a train network application level control software automation test method, comprising steps of beginning a test, importing various transmission protocols of a detected train network application layer control software, performing analysis and determination on variables in various data transmission protocols, storing the variables into a variable database, compiling a protocol conversion program in order to realize data conversion between an Ethernet protocol and various data transmission protocols, importing and executing preset test cases to perform test on various control software, if the test result is consistent with the expectation value, determining the control software to be qualified, if not, determine the control software to be not qualified. The test method of the invention is simple in operation, high in efficiency and low in cost.
Description
technical field [0001] The invention mainly relates to the field of train network technology, in particular to an automatic test method for control software of a train network application layer. Background technique [0002] At present, most companies in the rail transit industry can provide train network control software, and their network platforms are relatively unified and mature in terms of hardware and underlying drivers. Most of the functions are realized through the control software of the train network application layer, but different application fields and different project backgrounds cause large differences in functions between projects under a unified network platform. In recent years, more and more vehicle-mounted devices are connected to the train network, the data flow carried by the train network is increasing, and the functions of network control software are becoming more and more complex, resulting in greater differentiation. [0003] At present, there a...
