Batch occur and be not easy to find, so to intelligent electric energy meter software carry out unit testing be necessary.
Electric energy meter software unit testing is to survey unit to most I in software to be checked and verified, i.e., to every in software
Individual function is tested.But function is not an independent program in itself, therefore to needing to consider during function progress unit testing
The contact of the function and other functions.Unit testing can be early stage electric energy meter software life cycle, can degree of knowing in early days
Measure coverage information.Unit testing checks function performance according to intelligent electric energy meter software-implemented fault injection, and intelligent electric energy meter is newly organized
The code write can carry out unit testing immediately, so by intelligent electric energy meter software unit testing for improve electric energy meter software
Quality it is significant.
The content of the invention
For realize the present invention purpose, i.e., " by intelligent electric energy meter software unit testing for raising electric energy meter software
Quality " present invention intend use following technical scheme.
The first step, the unitunder test to intelligent electric energy meter software unit carry out code inspection and complete static analysis；
Second step, establish sequence management of test cases and to above-mentioned unitunder test complete design test case；
3rd step, unit under test is tested；
4th step, the unit testing for completing the intelligent electric energy meter software are evaluated and drawn a conclusion.
Preferably, described static analysis refers to enter above-mentioned unit under test the coding rule inspection of line code and generated quiet
State analysis report.
Preferably, first having to establish sequence one group of test case of management when carrying out above-mentioned second step, after sequence is built up,
Test Sample Design is carried out to function, external function is driven piles, sets expected input and output；
Then test is performed to test case, if the reason for test is not by needing and finding problem in time re-starts survey
Examination；The information of coverage rate, including sentence covering rate and branch covering rate are checked if test passes through, if coverage rate reaches 100%
Then carry out in next step, otherwise continuing design test case.
Preferably, program logic structure figure is formed simultaneously to tested function from LDRA Testbed when writing test case
Marked with numeral.
Preferably, LDRA Testbed are selected according to the design test case completed according to above-mentioned 3rd step, the 4th step
The unit testing for completing to test and generate test report completion intelligent electric energy meter software is evaluated and drawn a conclusion.
The beneficial effects of the present invention are by being tested intelligent electric energy meter software unit to each letter in software
Number carries out test and realizes that surveying unit to the most I of intelligent electric energy meter software unit is checked and verified, improves intelligence to realize
The quality problems of electric energy meter software create condition.
Brief description of the drawings
Fig. 1 illustrates the schematic flow sheet of the present invention (for summary diagram).
Fig. 2 illustrates program logic structure figure.
Embodiment
Told about in detail below according to the schematic flow sheet of the invention shown in Fig. 1,
Example one：The present invention assists to complete using LDRA Testbed instruments, and intelligent electric power meter hardware uses STM32F103
Processor, intelligent electric energy meter software development environment are IAR7.0.
Program elaborates by way of example for unitunder test 101 and demand and design documentation 102：
The static analysis of the first step, LDRA Testbed to intelligent electric energy meter software code is directly soft using intelligent electric energy meter
The standard of part industry accreditation is MISRAC-2012；Pile function processing is carried out to said procedure simultaneously, found from program above
GetMeterRunStatus, TranslateStatus0or1, EventMagneticBegin, EventMagneticend be from
The function being called in other functions, it should which piling processing is carried out to it；GetMeterRunStatus,
TranslateStatus0or1, the two pile functions take part in computing and call, it is necessary to set different return values to it；
EventMagneticBegin, EVentMagneticend do not use its return value, without parameter call, therefore to this yet
Two pile functions need not be handled.
Second step, LDRA Testbed can form program logic structure figure as shown below to tested function, and use
Numeral is marked, and the logical relation of tested function is combined according to this figure, and point being tested can be clear that according to figure below
Branch will become green,
The program logic structure figure according to Fig. 2, design test case are as follows：
TC1：Test if (EventMagneticSecond==EVENT_RTC_SECOND) is true, terminates and performs.Specifically
Data such as following table：
The test case 1 of table 1
TC2：Test if (EventMagneticSecond==EVENT_RTC_SECOND) is false, if (1==
TranslateStatus0or1 (＆MagneticRealStatus ,s ＆EventMagneticStatusUse, ＆
EventMagneticDuration, DurationTime, EventMagneticJudgeStatus)) it is true, if (1==
MagneticRealStatus) it is true, specific test data such as following table：
The test case 2 of table 2
TC3：Test if (EventMagneticSecond==EVENT_RTC_SECOND) is false, f (1==
