Description
Technical Field
The invention relates to a software testing system of a communication radio station, which can perform software testing work on various types of communication radio stations.
Background
With the development of wireless communication technology, the types of current communication equipment are gradually complicated, and radio stations in the communication equipment are perfected and developed in various stages, and are now widely applied to scientific research, even various fields of social life such as production economy and the like. Because the radio stations have a great variety, cover the complicated signals of each wave band, the interfaces with different specifications, the diversification of indexes and functions, the development of the current and new high-tech wireless communication technology cannot be met only by using the traditional manual testing instrument or simply using a narrow and targeted simple testing system to test the radio stations. An open automatic test system ats (automation test system) with high mobility has become necessary.
The aviation radio service is the basis for guaranteeing the aviation order, and the carrier of the aviation radio service is radio waves. The information exchange between the aircraft and the outside world during air flight is almost completely dependent on the aviation radio service, so the aviation radio service plays a crucial role in guaranteeing the safety of air traffic. However, with the recent gradual expansion of the commercial scale of civil aviation, the dependence of civil aviation on radio services has also gradually increased. The development of electronic technology has improved the function and performance of the aviation radio station. As an airborne communication device, an aviation radio station requires regular power-on checks to keep its function and performance in a good state, as compared with ordinary electronic devices. The aviation radio station test system needs to simulate the signal environment on the airplane, provide necessary excitation signals for the normal work of the radio station and receive response signals output by the radio station. The test system of the aviation radio station is a comprehensive platform which takes a computer as a control core, a comprehensive test instrument as a support and an interface card/adapter as a bridge and integrates control, acquisition, processing, storage, analysis, display and printing. The external interface signals of the radio station comprise a power supply, a control signal, audio and radio frequency signals. The power supply provides power supply signals for the work of the radio station, generally +27V, and some radio stations also need a single AC power supply of 115V/400 Hz; the control signal mainly controls the power switch, working frequency, receiving and transmitting state, modulation mode, squelch switch, working mode, etc. of the radio station, which is the core of controlling the radio station work, some radio stations are all provided in the form of discrete interface, and most radio stations are provided in the form of three-wire serial code, RS422, 1553B bus, ARINC429 bus or FOCTl8977 bus interface combined with discrete interface by the prescribed coding format. Different stations generally require different control signal environments, and even if the electrical interface characteristics are the same, the encoding formats are likely to be different. It is necessary to design corresponding control interfaces for different stations, which is a core and difficult point of constructing a test system, because besides providing electrical characteristics of various control signals, it is also necessary to satisfy logical relationships among various control signals. According to the test requirements of the radio station, the required universal instruments comprise an audio signal generator, a radio frequency signal generator, a digital meter, a power meter, a frequency meter, an oscilloscope, a modulation degree tester, a distortion degree tester and other equipment; attenuators and spectrum analyzers are also commonly used test instruments, depending on the transmit power of the station and the test items. At present, various types of radio comprehensive testers have appeared, all of which integrate an audio signal generator, a radio frequency signal generator and various commonly used testers together and have functions of program control interface and memory. The test process of the radio station comprises the processes of setting the working mode and working frequency of the radio station, setting the working state of a test instrument, processing a test result and the like, in the whole process, the time for setting the working frequency of the radio station is longest, particularly, the test of a short-wave radio station transmitter requires retuning when the frequency is changed, tens of seconds are required when the frequency is short, and some frequency points even need to be repeatedly tuned; from the whole testing process, basically all items need to be tested under the same frequency point. On the other hand, the radio comprehensive tester of the test radio station has 2 test states of receiving and transmitting, and can simultaneously test the main indexes of the receiver, such as audio output, distortion degree, signal-to-noise ratio and the like in the receiving state; in the transmitting state, the main indexes of the radio station transmitter such as carrier error, carrier power, modulation degree and the like can be tested simultaneously; the multifunctional and highly integrated characteristics of the radio comprehensive tester create conditions for parallel testing of multiple items of radio stations. Due to the fact that the radio stations are various in types, different in technical content, inconsistent in technical specification indexes and interface characteristics, many in test items and different in technical indexes. If a traditional instrument is adopted for testing, a plurality of testing devices and instruments are required to jointly complete the testing, so that the testing equipment has poor universality, low automation degree and complex operation. For testers, the core test items and the test procedures are different from each other. Moreover, testing of the radio station is a complex process, and besides the radio station itself, a large number of measuring instruments are required to construct different test data sets and the like. The prior avionic maintenance detection equipment mainly adopts a traditional instrument, and a test system formed by the traditional instrument has the defects of multiple instrument varieties, large volume and heavy weight; the test is carried out manually, so that the time and labor are wasted, the test error is large, and the requirement of battle training on the quick mobility of the maintenance guarantee is difficult to meet.
The aeronautical communication station is an onboard communication device installed on an airplane, and one of important means for providing the communication capability of bidirectional voice and data in the visual range between airplanes or between airplanes and the ground. With the proposal of a Software Defined Radio (SDR) concept, the technical complexity of radio software is continuously improved, and the role of the software in the radio station is increasingly greater, which puts higher requirements on the completeness, the correctness and the accuracy of the functions of the radio station software. The software flow design test process of the test system is a guide and a basis for test program development, but if the characteristics of equipment are not considered, the test process is simply compiled according to the test process, so that the test process is repeated, the test efficiency is reduced, and the working life of a tested piece is influenced. Therefore, on the basis of deeply researching the characteristics of equipment, the relation among test items and the test method, the test flow needs to be optimized, the repeated operation of the test process is avoided, and the detection work efficiency is improved. The radio station has the characteristics of multiple working modes, multiple test items, multiple test frequency points and the like, and the test items and the test process have great correlation. Therefore, the current test for station software faces the following problems:
(1) the aviation communication radio station can operate only by being connected with other equipment, and the test environment is difficult to build. Under a real operating environment, the aviation communication radio station can execute the test case only by matching with various test instruments and a platform for software test. There are high requirements on the scope of knowledge that the tester needs to be involved with. The test cannot be rapidly and effectively unfolded.
(2) The test case design and execution are disjointed, and the test efficiency is low. The design and execution of test cases are often performed separately. And other problems may be found in the execution process, so that the use case needs to be redesigned and executed again. So that the tester needs repeated labor and efficiency is low.
(3) The instrumentation operates manually, making the execution of test cases slow. At present, instruments required by testing are mostly manually controlled, instrument parameters need to be set according to requirements, unnecessary waste of use case execution time is caused, manual setting and possible input errors cause use cases to obtain wrong conclusions.
(4) Test data multiplexing is difficult. During use case execution, a large amount of test data may be used for the same function. Therefore, maintenance, migration, etc. of test data requires manual recording or replacement by a tester. The multiplexing of test data is not facilitated.

See fig. 2. The automatic test platform for the radio station software comprises three layers of structures including an interface, a function and a transmission. The interface layer is used for displaying and controlling the automatic test platform of the radio software and is also used as a module which is most contacted by a user directly. The system mainly comprises a case editing interface, and a user can selectively use specific functions in a functional layer to construct a test case of the user; and the error message and data display interface is used for displaying errors and data when a user executes a test case or the bottom layer of the automatic test platform of the radio station software, so that the user and a developer can quickly position the problems conveniently. The system/engineering menu is a radio software automatic test platform for storing user test cases, creating new projects, opening historical projects and the like, and provides a radio software automatic test platform which has strong functions, is friendly in interface, can flexibly develop test tasks and can execute the test cases in batches through a man-machine interaction mode for testers.
The functional layer is the most core and basic structure in the radio station test and comprises six main modules. The system mainly comprises a control module, a test data management module, a test data generation module, a test script management module, an interface management module and an automatic execution module of the instrument.
The interface management module mainly completes the management of interface control formats between radio stations and peripheral equipment, and because the interface formats between each radio station and the peripheral equipment are different, in order to facilitate the management, a uniform format must be formulated to decompose the interface and store the interface attributes. The interface management module stores the XML format, and converts the XML file into an interface script used in the test script by analyzing the XML file when in use. The interface management module includes the length of the interface, the signaling code id of the interface, the specific parameter value of the interface, and the bit for checking the error. If an interface needs to be designed more complicated for the reason of the requirement, nesting can continue in the value element and the unit of data can be changed for various requirements.
The test data generation module generates test data according to an interface format of the radio station, a combined test data set meeting a specific combined coverage standard is generated by adopting a combined test data generation method, one interface is abstracted into an entity influenced by a plurality of variables, and the value of each variable is discrete and limited.
The test data management module manages reusable test data, generates an XML entity document according to a specified format, provides functions of adding, deleting and copying online editing, abstracts the test data of some general radio station functions into reusable TOD time setting, sets test data according to channel parameters, stores the data in an XML format, classifies a test data set according to normal test and abnormal test when designing a test script, takes the normal test data as a background and the abnormal test data as a background, marks specific error fields in the test data by red fonts and shows the specific error fields in a table form in a platform.
The test script management module is internally provided with an intelligent auxiliary code compiling tool which automatically generates script fragments and logic according to the keywords, mainly completes the structure management of the test script and the specific content of the test case, sends and receives data, controls the generation of instrument data and the introduction of data, and tests different test contents. And according to the hierarchical relation and the name of the test case created by the user, creating a corresponding folder and a python file corresponding to the test case under the engineering directory. And generating a template character string according to the format of the interface, replacing keywords in the template character string with specific values in the interface, and directly replacing the template according to the code style of python to automatically generate a unified frame of the test case. The keywords are marked with different data types when being stored, and the problems of type conversion among numerical values and the like do not need to be considered, for example, fail is returned when the test fails, and success is returned when the case test passes.
The instrument control module mainly controls instruments, separates instruction sets of the instruments from instrument control, divides the instruments according to the application of the instruments and specific manufacturers or specific models, and divides the instruments into signal sources, comprehensive testers, frequency meters and power meters or newly adds instruments required to be used in a testing process according to a specified format. The SCPI command of the instrument is stored in an XML format, the frequency value of a signal source and the square wave output by the signal generator are set, and the signal is sent to the instrument by using communication modes such as TCP, UDP, serial ports and the like. For example, the signal generator is set to output square waves of 'SOURce 1: funtionsquare', the signal SOURce frequency value is set: 'SOUR: FREQ1000 MHz'. The specific frequency value can be changed by the user according to the requirement of the user. The SCPI commands for the other instruments are similar.
The automatic execution module mainly completes automatic execution of the test script, when in use, firstly initializes the test environment, checks the integrity and the availability of the test environment, then traverses the test script to be executed, loads the script into the memory for execution, and finally feeds back the execution result and the execution progress of the script. Based on the test script management module, the execution condition of the test case is given by a first-in first-out queue through a unified return value, fail or success, the test result is summarized in real time, and the passing, failing and unexecuted proportion is displayed in a pie chart form. In the execution of the use case, the data transmitted to the radio station and the data returned from the radio station are displayed in the platform in real time.
A transmission layer: the communication between the radio station software automatic test platform and the radio station or the instrument does not belong to the function of the radio station software automatic test platform. But is an essential part of the overall test procedure. The communication modes supported by the aviation communication radio station comprise a network port, a serial port, 429 and the like. The user needs to select a communication mode before the next operation can be performed. At present, the platform provides support for all the three communication modes. And uniformly packaging the data into a Bus parent class. Each independent communication means inherits the parent class. This class provides a method for send and recv. And calling is needed when the test case is written. While the specific subclass requires rewriting both methods. For example, the socket library function provided by python needs to be called in the network port communication mode to realize sending and receiving. The serial port also calls the res library function provided by python for communication. 429 the dynamic link library provided by the station developer needs to be loaded and the method provided in the dynamic link library is called, thereby realizing communication. The current platform only supports the three communication modes. If other communication means are needed in the new type of aeronautical communication station afterwards. Only one other subclass needs to be implemented to rewrite the send and recv methods. Not much extra code is required and no adjustment of the logic of the whole communication is required.
See fig. 3. The working process of the radio station software automatic test platform comprises the following steps: creating or editing projects on a radio station software automatic test platform in a test computer, designing different test scripts aiming at different functions of a radio station, judging whether the test scripts are edited, judging whether the test scripts are executed if the test scripts are edited, if so, starting the test, selecting a case to be executed by a user, starting the execution, and generating a test result in real time; and waiting for the completion of the execution of all the test scripts, judging whether the test scripts are correctly executed and pass the logic judgment of the test case, and if not, requiring a tester to check whether the test case is designed or the radio software. If the test case is a problem, the test case needs to be edited again and a new round of case execution is started. If the problem is the problem of the radio station software, the problem needs to be fed back to the developer, and the execution of the use case is started again after the radio station software is modified.
The main contents created or edited by the station software automatic test platform comprise: writing peripheral Interface (ICD) information, and storing data such as ICD information, data sets, instrument control commands and the like by using an Xml data format. So that the data can be read or modified the next time the platform is used. Before the ICD message is created, the communication mode used in the test is selected.
When a specific ICD Message is written, a Message type is provided in the code logic of the automatic test platform of the radio software, a Message part object of sub-messages, such as byte number, signaling code, checksum, data and the like, in the ICD Message is contained in the Message type, after an ICD Message is created, the specific Message part is added into the Message object, and the edited data of the user is assigned. After clicking and storing, the user can generate an XML file displayed in the similar interface management module according to a specified format. Before writing a test case, a user needs to generate a latest entites file, the file contains the bus type selected by the user at this time, specific ICD information, and the content of internal sub-information, and is stored in an engineering directory of the user in a python script form, and finally the entites file is called in the test case of the user, so that the automatically generated test case can become a complete python executable program.
The main basis for the tester to design the test script is also the content in the ICD message. The corresponding ICD message is selected according to the actual function. An automatic code generation tool can be used, or a tester writes a test case by himself, uses the well-defined ICD message, and sends or receives return data of the radio station. And finally, the tester judges the reason of failing to pass the script according to the passing condition of the test script and the sent and received data, if the script is in a problem, the tester modifies the test script and executes the test script again, and if the script is in a problem of the radio software, the developer needs to modify and then perform regression test work again.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
