Sending control method for communication protocol testing

Abstract

The invention relates to a sending control method for communication protocol testing, and the method is used for achieving testing of a communication interface and a protocol thereof. The method is characterized in that a sending data text input through the method comprises sending data, labels, variables, data calculating and transferring functions, sending control functions and testing parameter setting functions; after analysis processing and decomposition, the text is transmitted to data calculating and transferring processing, sending control processing and testing parameter setting function processing; the sending control processing carries out circulation and skip control on the data calculating and transferring processing, and carries out time-triggered control and condition-triggered control on data sending processing after sending data generation processing and caching processing; the condition-triggered control generates conditions triggering data sending processing through characteristic judgment according to receiving data obtained through receiving data processing. The method achieves the functions of automatic changing of testing conditions, automatic data changing and framing, data calculating, format conversion, circulated sending, condition skipping, and automatic receiving and replying.

Description

Technical field [0001] The invention relates to a transmission control method for communication protocol testing, belonging to the field of communication interfaces and protocol testing. Background technique [0002] With the development of communication technology, testing of various communication interfaces and their protocols is a necessary part of technology development and product inspection. The existing communication interface and its protocol test can only provide manual calculation of values, manual completion of conversion data, manual setting of multiple data frames, timed loops, and the function of triggering after the received frame is completely matched. It does not provide more convenient automated protocol testing. Features. The Chinese invention patent "Testing method and system of communication protocol interface (application number: CN201110279981.4) introduces a communication protocol test method, such as figure 1 Shown. The communication protocol test metho...

Problems solved by technology

The sending part of the communication protocol test method can realize the selection of the sent data through the test script and the protocol test library, but the test system does not include the control of the time, cycle and trigger of the test sending data frame, and can only realize the communication data generation , sending, can only be used to verify the consistency of the sent data and the received data generated according to the test protocol library, and cannot adapt to the situation where the data protocol is different due to different device characteristics and interface characteristics, and cannot complete complex, long-term, and constantly changing Conditional auto-test function

[0003] With the increasingly complex serial communication protocol, the existing serial computer debugging tools can no longer meet the debugging needs

Existing serial port computer debugging tools can usually only complete simple serial port transceiver control and cyclic sending functions
