Domain.
Background technique
With development communication technologies, the test of various communication interfaces and its agreement is the one of technological development and the examination and test of products
A necessary links.Current existing communication interface and its protocol test, can only provide artificial evaluation, be accomplished manually conversion number
According to, the function that triggers after a plurality of data frame, timing cycle, receiving frame exact matching is manually set, do not provide more easily from
Dynamicization protocol test function.Chinese invention patent " communication protocol interface test method and system (application number:
CN201110279981.4 a kind of communication protocol test method) is described, as shown in Figure 1.The communication protocol test method is based on
The function of test script module invocation protocol test library, simulant-client behavior, and test data are sent to measurand, lead to
It is received back complex data with logical services simulator, the test script module is transferred to and is verified.The communication protocol test side
The selection to sent out data may be implemented by test script and protocol test library in the transmitting portion of method, but the test macro is not
Comprising to test send data-frame times, circulation, triggering control, can only realize communication data generate, send, be only used for testing
Card send data and according to test protocol library generate reception data consistency, can not adapt to data protocol because device characteristics,
Interface features are different and different situations, are unable to complete the autorun of complicated, prolonged, continuous change condition.
Increasingly sophisticated with serial communication protocol, existing serial ports computer debugging tool is no longer satisfied debugging and needs
It wants.Existing serial ports computer debugging tool is typically only capable to complete simple serial ports transmitting-receiving control and cycles through function.However,
Currently to the test of serial communication reliability, it is also necessary to retransmit after sending delay, waiting reply to serial ports, modify automatically
Frame data are sent, check code calculating is automatically performed and fills in.For this purpose, proposing that serial port protocol sends the new demand of test software.
Summary of the invention
The purpose of the present invention is to propose to a kind of sending control method of communication protocol test, the hair of designed test input
Send data text, in addition to comprising send data, also comprising label, variable, data calculate and transfer function, send control function with
And function is arranged in test parameter, to realize that test condition changes automatically during communication test, realizes automaticdata variation
Agreement framing afterwards realizes that convenient and fast data calculate and format conversion, realize it is more flexible cycle through and conditional jump, realize
According to the automatic answer function for receiving data.
The present invention provides a kind of sending control method of communication protocol test, this method packet to solve above-mentioned technical problem
Containing following steps:
Step 1 carries out text resolution processing to the transmission data text of communication protocol test, decomposites and sends data, mark
Number, variable, data calculate and transfer function, send control function and test parameter function is arranged；
Step 2, transmission control processing and receive the provided transmission control function of text resolution processing, are ready to carry out including following
Ring and the transmission jumped including control, time trigger control and condition triggering control control；Test parameter is arranged function and handles

Step 3, in the case where recycling and jumping control, send that data, label, variable and data calculate and transfer function input
It is calculated to data and conversion process, acquisition data calculates and the processing result of transfer function and the current value of variable；
Step 4, transmission data, the current value of variable and data calculate and the processing result of transfer function is input to hair
It send data generation to handle, generates outgoing data；
Step 5, transmission data generate outgoing data caused by processing and are saved by caching process；
Step 6, when time trigger control and condition triggering control trigger condition meet when, data sending processing will cache
Outgoing data from communication transmission interface send.
Wherein, the parameter of communication protocol test includes that the setting to communication transmission interface and communications reception interface is joined
Number.
Further, the parameter of communication protocol test includes the setting parameter to test environment.
Further, the parameter of communication protocol test includes processing, statistics, the measurement to data are sended and received
With the setting parameter of display.
Further, time trigger control is controlled comprising Time-delayed trigger.
Further, time trigger control is controlled comprising clocked flip.
Further, the reception number that condition triggering control is obtained according to reception data processing from communications reception interface
According to generating trigger condition by receiving data characteristics judgement, data sending processing controlled when trigger condition meets by outgoing data
It is sent from communication transmission interface.
Further, the step 1 to step 6 can recycle, and the text resolution of step 1 handles foundation in each cycle
It sends control function and dissection process only is carried out to partial content in transmission data text.
The functional block diagram of communication protocol proposed by the invention test sending control method as shown in Fig. 2, this method it is beneficial
Place is by, comprising symbol definitions such as variable and functions, more flexible test control may be implemented in sending data text
System.Specifically, sending, the label in data text, variable, data calculate and transfer function, are surveying to realize and send data
Automatic calculating and convenient generation during examination.Function is arranged in the test parameter sent in data text, can be used for testing
The parameter characteristics such as speed of dynamic adjustment communication interface in the process change test total environment according to different test requests.Test
Parameter setting function can also carry out further data analysis to sending data and receiving data, such as: it extracts and receives data
Middle particular piece of data is simultaneously converted to the corresponding numerical value of actual physical meaning and is shown；Success rate is communicated in statistical test procedures；
Sending and receiving data is changed in the display content and form of display window；Test post is exported in display window.
Control function is sent for implementing more flexible control to the data transmission procedure that communication protocol is tested, to simplify certainly
Dynamic test process, provides richer test function.Since data transmission procedure includes that data calculate and conversion process, transmission number
According to generation processing, outgoing data caching process and final data sending processing.The transmission that the present invention is implemented controls
Two controlling units.One controlling unit is for the circulation for sending data generation and to jump control, another controlling unit is
The time trigger control and condition triggering control that outgoing data starting is sent in control caching.Send the setting of control mode still
