Description
Technical field
The present invention relates to a kind of protocol testing method of embedded software and devices, are applied to embedded software test and lead
Domain.
Background technique
The continuous of computer technology application is popularized, so that real time embedded system plays work in more and more fields
With.These fields include Aeronautics and Astronautics, Industry Control, traffic, medical treatment and military field etc..It is not difficult to find out that these fields are to soft
The key property that part requires is exactly reliability, because the software in the field can directly or indirectly influence the mankind once failing
Lives and properties and ecological environment safety.
So-called real time embedded system refers to that those run in real time embedded system, plays the soft of core control action
Part.By the particularity of locating running environment and the task completed, real time embedded system has compared with being normally applied software
Its own characteristic.These characteristics are mainly shown as real-time, reactivity and insertion characteristic.And the communication party between embedded system
Formula is varied, and communication protocol is generally defined by user oneself, the communication protocol of such many and diverse multiplicity, how to guarantee stability with
Correctness can only be guaranteed that there are no a complete and effective testing schemes by user oneself at present.
Built-in system software protocol test, which can be divided into, to be tested on host and tests on target machine, although in place
Test is shown as more convenient and flexible on host, but how perfect the test no matter carried out on host is, on target machine
Test is still irreplaceable, because some problems are tested only on target machine is likely to confirmation and discovery.Based on test side
The test of target machine is divided into three classes by the difference of formula: pure software emulation testing, semi-physical simulation test and object test.Due to
Object test it is targeted be whole system, therefore test cost is expensive, and test period is long.And pure software emulation testing can not mould
The true protocol scheme of quasi- embedded software, and can have error, cause the confidence level of test result not high.
Summary of the invention
Present invention is primarily aimed at proposing the protocol testing method and device of a kind of embedded software, by host,
Protocol test agency and system under test (SUT) composition, wherein host is to be equipped with to act on behalf of matched software with protocol test, and provide
Parameter configuration interface, the configuration interface that user is provided by host software, and the frame structure of user configuration protocol frame is filled, it produces
Raw agreement content frame and agreement frame timing, are connected by system bus interface with system under test (SUT), and the software of host's generator terminal is only
Configuration method and control instruction are provided, so that the confidence level of embedded software protocol test increases substantially.
A kind of the technology of the present invention solution: protocol testing method realization of embedded software are as follows:
It is acted on behalf of via coffret from host to protocol test and sends configuration data frame, the configuration data frame is for matching
Set the bus data output format of protocol test agency；
After the configuration data frame that the protocol test proxy resolution receives, given via coffret feedback configuration response message
Host, host judge the configuring condition that protocol test is acted on behalf of according to response message；
According to the configuration data frame and in the configuration response message of host and protocol test agency's exchange, agreement is surveyed
Try the output frame format of proxy configurations bus interface；Frame format based on output, the automatic filling corresponding data of protocol test agency,
And data interaction is carried out by bus interface and system under test (SUT).
Based on the coffret that the host is configured, determine whether host and the connection of protocol test agency have
Effect, and according to it is identified as a result, configuration host coffret parameter, with adapt to protocol test agency transmission connect
Mouthful.
The configuration data frame includes the output data frame format of configuration protocol test agent, output data frame source and defeated
The transmission opportunity of data frame out.
The output data frame source, which is included in, to be automatically generated in protocol test agency and is made by oneself in host by user
Justice.
The transmission opportunity of the output data frame includes regularly sending data frame, sending data frame, the transmission of response formula at random
Data frame and follow host send data frame.
A kind of protocol testing device of embedded software, described device include:
Transmission interface unit is configured, the configuration transmission interface unit is to configure the coffret parameter of host, so as to
The coffret of host can smoothly transmit data；Configuration data frame unit, the configuration data frame unit is in protocol test
After agency's starting, the exchange configuration output result between host and protocol test agency；User surveys according to host and agreement
Exchange configuration exports the transmission opportunity as a result, the bus data frame to determine protocol test agency between examination agency.
A kind of protocol testing device of embedded software, described device include:
Transmission interface unit is configured, the configuration transmission interface unit is that the coffret of configuration protocol test agent is joined
Number, so that protocol test agency can send and receive data；Output data frame configuration unit, the output data frame configuration are single
Member generates corresponding bus data output frame after parsing configuration data frame, according to the content of configuration data frame.
The advantages of the present invention over the prior art are that:
(1) the external protocol content i.e. agreement timing of true embedded software can be generated；
(2) embedded software protocol test is with a high credibility；
(3) embedded software protocol test problem spreadability is wide.
The characteristic for being usually embedded formula system is mainly shown as real-time, reactivity and insertion characteristic.And embedded system it
Between communication mode it is varied, communication protocol is generally defined by user oneself, and how the communication protocol of such many and diverse multiplicity protects
Stability and correctness are demonstrate,proved, can only be guaranteed at present by user oneself, there are no a complete and effective testing scheme, and it is general
Embedded software test, the test of target machine is divided into three classes by the difference based on test mode: pure software emulation testing, half
Physical simulation test and object test.Due to object test it is targeted be whole system, test cost is expensive, test week
Phase is long.And pure software emulation testing can not generate the external protocol content i.e. agreement timing of embedded system, and can exist and miss
Difference causes the confidence level of test result not high.Semi-physical simulation test can carry out piecemeal test to embedded software, and providing can
The simulated environment leaned on, so that the confidence level of the protocol test of embedded software improves, and due to all protocol contents and association
View timing is all configurable, so test problem spreadability is wide.
