Description
Technical field
The present invention relates to a kind of method for testing software of Simulated Spacecraft unit exception.
Background technology
Spaceborne device is numerous, and the complete unit related to is numerous, and constituent parts achieves the unit test equipment of different framework according to spaceborne device concrete condition.Spacecraft-testing software needs to examine these units and synthetic operation situation.Before software drops into formal use, unit testing, integration testing, configuration item test and system qualification testing need be carried out, to find software defect, improve software quality.
During configuration item test, various exception must be applied with the robustness of verifying software to software, find out leak wherein.But at present without effective hardware anomalies applying method, when its reason is software work, can not spaceborne device be damaged, real airborne equipment cannot be used to apply abnormal, at present also without the exception of equipment various on miscellaneous equipment imitating shell, therefore software configuration item test job cannot be carried out.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, a kind of method of testing of spacecraft-testing software is provided, can not the problem of Simulated Spacecraft unit exception when can solve software test, simulate various certainty fault and chance failure.
The object of the invention is to be achieved through the following technical solutions: a kind of method for testing software of Simulated Spacecraft unit exception, it comprises following steps:
(1), define hardware manager and hardware adapter, hardware manager and hardware adapter are connected each other by configuration file;
(2), set up hardware adapter list based on CBaseDriver in hardware manager, and define hardware adapter interface;
(3), by the real equipment class in configuration file virtual unit class is changed into, the information processing function of defining virtual equipment class
(4) abnormal before free of contamination operation injection is carried out, and with virtual hardware Simulated Spacecraft equipment;
(5), the operation to real hardware or the operation to virtual hardware are encapsulated in hardware adapter, through hardware adapter Card read/write, process function and ID exclusive number;
(6), hardware manager searches corresponding hardware adapter according to the hardware ID number of unified distribution;
(7), particular hardware operation is performed by hardware adapter interface.
Described hardware adapter list is the version of one-to-many.
Described configuration file is XML format configuration file.
The invention has the beneficial effects as follows: define hardware manager, hardware adapter, the operation of real hardware, virtual hardware is encapsulated in hardware adapter interface, adopt virtual hardware Simulated Spacecraft equipment, various certainty fault and chance failure can be simulated, use the test case of the method exploitation can accomplish tested software pollution-free, can not the problem of Simulated Spacecraft unit exception when solving software test.
Accompanying drawing explanation
Fig. 1 is test schematic diagram of the present invention;
Fig. 2 is hardware manager Organization Chart of the present invention.
Embodiment
Technical scheme of the present invention is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As Fig. 1, a kind of method for testing software of Simulated Spacecraft unit exception, it comprises following steps:
(1), define hardware manager and hardware adapter, hardware manager and hardware adapter are connected each other by configuration file;
(2), set up hardware adapter list based on CBaseDriver in hardware manager, and define hardware adapter interface, the Major Members of CBaseDriver is in table 1
Table 1CBaseDriver Major Members table
Hardware adapter list is numbered mark with key word ID, and in identification information write configuration file driver.xml.Hardware manager uses ID numbering to search a certain hardware adapter (may be real hardware, also may be virtual hardware), by interface function operation particular hardware or the virtual unit of this hardware adapter.
Definition format in driver.xml is as follows:
(3), by the real equipment class in configuration file virtual unit class is changed into, the information processing function of defining virtual equipment class
(4) abnormal before free of contamination operation injection is carried out, and with virtual hardware Simulated Spacecraft equipment;
(5), the operation to real hardware or the operation to virtual hardware are encapsulated in hardware adapter, through hardware adapter Card read/write, process function and ID exclusive number, hardware manager searches related hardware according to ID, realizes operation that is true, virtual unit;
(6), hardware manager searches corresponding hardware adapter according to the hardware ID number of unified distribution;
(7), particular hardware operation is performed by hardware adapter interface.
Described hardware adapter list is the version of one-to-many.
Described configuration file is XML format configuration file, is numbered by the ID of hardware adapter and in type write configuration file, reduces the coupling of code.
As Fig. 2, the basis of CBaseDriver achieves RS422 serial communication class of operation C422Driver, 1553B bus communication class C1553Driver, and virtual hardware class CVirtual1553, CVirtual422.
If carry out software test, use the virtual cpu CPU based on 1553B communication that is virtually reality like reality, as long as testsoft.C1553Driver to be changed into the title of virtual cpu class.
To simulate cpu fault, defining virtual CPU class CVirtuaCPU.The data buffer simulating one piece of 1553B of CVirtualCPU class, and define the read/write function for buffer zone.The various actions of true CPU when taking orders of the information processing functional simulation of CVirtualCPU class.The information processing function code example of CVirtualCPU class is as follows:
The information processing code of above code and true CPU is similar, but uses auto-coding instrument the information processing code of true CPU to be converted into the information processing code of CVirtualCPU class, thus generating test use case fast.
Claims (1)
