Brief description of the drawings
Fig. 1 is the flow diagram of one embodiment of the invention.
Embodiment
It is the specific embodiment of the present invention below, technical scheme is further described, but the present invention is simultaneously
It is not limited to these embodiments.
Carry out the various exemplary embodiments of detailed description of the present invention now with reference to attached drawing.It should be noted that：Unless in addition have
Body illustrates that the module and the positioned opposite and step of step otherwise illustrated in these embodiments does not limit the scope of the invention.
At the same time, it should be appreciated that for the ease of description, the flow in attached drawing is not merely individually to carry out, but multiple steps
The rapid progress that intersects.
Due to embedded software have the characteristics that it is soft combination of hardware it is close, in test process often using simulation method carry out
Test, to improve testing adequacy and validity.But simulation test process usually requires to be built according to different tested softwares
Substantial amounts of simulation model is found to support to test, in existing test method, test process is time-consuming and laborious and tests inefficient.
Embodiment one：
As shown in Figure 1, it is only one of embodiment of the present invention, in order to more convenient more simply to test embedded software
Qualification is tested, and the present invention proposes a kind of embedded software test method, comprises the following steps：
S1：The embedded software editted is burnt in memory；
Substantial amounts of simulation model need not be established to support to test, by embedded software direct burning into memory, you can effectively
Embedded software is read out and is tested.
Certainly, before step S1 is performed, data on memory is all wiped, prevent other data to embedded software
The test of part impacts.
S2：Run the embedded software；
Trial operation embedded software, it is complete to show embedded software, and the performance for also demonstrating that memory is the available of qualification,
It can use what the memory was tested for the embedded software, certainly, if during trial operation, embedded software can not be transported
Row is, it is necessary to replace memory, if repeatedly replacement may not operate, it is underproof that can directly prove embedded software.
The step for just for the sake of detection embedded software running environment.
S3：Using simulator write error configuration data to embedded software, whether observation embedded software continues to run with,
If embedded software continues to run with, embedded software is unqualified；Otherwise, step S4 is performed；
It is more multiple in progress even if embedded software can not represent embedded software as certified products with normal operation yet under trial operation
During miscellaneous operation, it would still be possible to failure occurs.
Embedded software has the ability of processing data, then the configuration data of one end mistake is write using simulator, is allowed
Embedded software is handled, simulate its wrong resolution capability and operation whether specification, if being written with the configuration data of mistake,
Embedded software remains to run, and illustrates that its wrong resolution capability is low, or its traffic direction is incorrect, can be shown that embedded
Software is underproof.
Conversely, embedded software cannot handle the configuration data of mistake, then it is probably qualification to illustrate embedded software, into
The test of row next step, performs step S4.
Certainly, before step S3 is performed, the configuration data of Edit Error.Edit the configuration data of a few class mistakes more, survey
Test result is more accurate.
S4：Write correct configuration data to embedded software using simulator, observation embedded software whether normal operation,
If embedded software normal operation, embedded software is qualification；Otherwise embedded software is unqualified.
In step s3, even if embedded software can differentiate the configuration data of mistake, embedded software is not also represented
One is set to qualification, need to further be simulated.
Correct configuration data is write using simulator, if embedded software cannot be handled, or is not normally functioning
Draw correct output parameter, then illustrate the incorrect accurately data-handling capacity of embedded software, be still unqualified
's.
Conversely, embedded software can run and can normally handle correct configuration data draw correctly output as a result,
Then illustrate embedded software for qualification.
Generally speaking：Test show that the requirement of embedded software qualification is：It is embedding when simulator write error configuration data
Enter formula software not continuing to run；And when simulator writes correct configuration data, embedded software normal operation, and can be normal
Processing draws correctly output result.
Embodiment two：
A kind of above-mentioned embedded software test method can conveniently test whether a kind of embedded software is qualified
Product, but test result be not once test can draw, it is necessary to carry out multiple test.
Also mention above, in the configuration data of Edit Error, edit the configuration data of a few class mistakes, test result more
It is more accurate.
Can rule of thumb have, the configuration data of mistake includes：Configuration data, the data encoding mistake of data length mistake
Configuration data, the configuration data of data exception, the configuration data of data type mistake and the configuration data that can not be read.
On this basis, step S3 is specially：
S31：Use simulator write error configuration data to embedded software；
S32：Simulator stops write-in data；
S33：Whether observation embedded software continues to run with, if embedded software continues to run with, embedded software is unqualified；
Otherwise, step S4 is performed.
And when performing step S3, step S31 to step S33 is repeated, until the vicious configuration data of institute is equal
After testing, embedded software does not continue to run with, then performs step S4.
Test must namely be repeated, after all wrong data all test once, if embedded software
Part is not run, then illustrates that processing of the embedded software for wrong data with discrimination is normal, can just carry out down like that
Face is further tested.
Above as can be seen that after write-in data, it is necessary to first stop write-in, represent that data write activity is completed, Yi Mianhou
The data influence test result of continuous input.
But importantly, before performing step S31, simulator is write to the error configurations data of embedded software
Empty.
Accomplish the rigorous accurate of test, be that the error configurations data of write-in cause shadow to test result below before avoiding
Ring.
The test of embedded software also has a step, carries out step S4, and step S4 is specially：
S41：Correct configuration data is write to embedded software using simulator；
S42：Simulator stops write-in data；
S43：Observe embedded software whether normal operation, if embedded software normal operation, embedded software for qualification；
Otherwise embedded software is unqualified.
Certainly, then before carrying out step S41, it is also desirable to the configuration data that will be write before using simulator is all removed,
Avoid disturbing.
Subsequently, the correct configuration data of input is complicated as far as possible or representative, and such aptitude test goes out
Embedded software data-handling capacity, if in the case of configuration data is complicated as far as possible or representative, embedded software
Part remains to normal operation and can normally handle show that correctly output is as a result, it is qualified that can then measure embedded software.
Whether a kind of embedded software test method of the present invention can qualified with Validity Test embedded software, simple easily behaviour
Make, testing cost is low.
The present invention is not limited to above-mentioned specific embodiment, and the invention may be variously modified and varied.Every foundation
The technical spirit of the present invention should be included in the present invention to embodiment of above any modification, equivalent replacement, improvement and so on
Protection domain.
