Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1, the variable-based dynamic data operation and management system includes a relational data storage management module, a dynamic variable data management module, and an external interface module. The relational data storage management module is used for uniformly managing data which are strongly associated and need to be stored permanently, such as format definition, parameter information, data structures and the like of test data. And the dynamic variable data management module takes out the data information in the relational data storage management module aiming at different test scenes and test processes, and analyzes the data information into variables to be injected into a dynamic data variable pool according to a uniform format. The external interface module is a black box capable of receiving external commands, and can access the dynamic data variable pool through a series of API functions. Also because the mode that adopts the black box, so under the prerequisite that realizes the interface, multiple optimization can be carried out in inside realization, like distributed execution etc. have very high expansibility. The functional blocks are explained in detail below.
1. Relational data storage management module
The relational data storage management module comprises a tested product information base, a test data message structure base and a test data and hardware resource binding information base, wherein the tested product information base, the test data message structure base and the test data and hardware resource binding information base are all realized by a MYSQL database.
The tested product information base mainly carries out all-around description and management on the information related to the tested system. The method mainly comprises a verification stage to which a tested product belongs, an affiliated project, an affiliated product type, the name, the number, the picture and other necessary description information. The specific attributes and the cross-linking relationship of the product information base to be tested are shown in fig. 2.
The test data configuration file is used as the output of the product detailed design stage, defines the functional data flow of the tested system and is a core input file in the test verification process. And after loading and analyzing the test data configuration file, extracting the structure information of the test data and storing the structure information in a test data message structure library for unified management. The test data message structure library includes a structure table of the message packet, a structure table of the signal in the message packet, and a structure table of the variable in the signal, and specific attributes and cross-linking relationships of the test data message structure library are shown in fig. 3.
The test data is in data communication with the system to be tested through a certain hardware resource, and after manual configuration, each test data can bind corresponding hardware resource information and is finally analyzed to a hardware resource layer, so that data interaction between the test data and the system to be tested is realized. The test data and hardware resource binding information base mainly comprises a node computer information table and a hardware information table. The specific properties and cross-linking relationship between the test data and the hardware resource binding information base are shown in fig. 4.
The general structure diagram of the relational data storage management module and the cross-linking relationship of each database are shown in fig. 5, the test data message structure library is respectively associated with the tested product information library and the test data and hardware resource binding information library, after the test data configuration file and the hardware resource configuration file of the tested system are imported into the relational data storage management module, the relational data storage management module analyzes the test data configuration file and the hardware resource configuration file, and fills the analyzed data into the tested product information library, the test data message structure library and the test data and hardware resource binding information library.
2. Dynamic variable data management module
Due to the insufficiency of the relational data storage management module in real-time, the data interaction between the test data and the tested product is seriously influenced. In order to solve the problem, a high-instantaneity memory database Redis is used for storing and maintaining dynamic test data, relevant information of test messages in a relational data storage management module is extracted and registered in a dynamic data variable pool. The dynamic data variable pool mainly comprises two parts: value key queue of test messages and structure key of test messages.
The Value key queue of the test message includes a message Value key queue, a signal Value key queue, and a variable Value key queue, and selects a < key, string > mode, as shown in table 1. In order to ensure the uniqueness of the key value in the Redis, a character string consisting of a message name and a message specification number is selected as the key value.
TABLE 1 Redis data storage Structure design-ID mapping
The structural key team of the test message selects the < key, hash > mode, and Redis designed as follows, as shown in table 2.
Table 2 Redis data storage Structure design-data Structure
It should be noted that all the x values in the table are extracted from the corresponding table in the relational data storage management module, the signal queue includes all the signals of the message, the variable queue includes all the variables of the signals, and the multi-layer nested hash structure is adopted to store all the structure information of the test message.
3. External interface module
The external interface module is responsible for remote calling through a ZeroRpc component, so that the external interface module is a black box capable of receiving external commands and can be accessed through a socket. Because the engine is a black box, on the premise of realizing the interface, the internal implementation can be optimized in various ways, such as distributed execution and the like, and the engine has high expansibility. For example: the external interface module can import a test data configuration file and a hardware resource configuration file of the tested system into the relational data storage management module; when the dynamic data service runs, if data needs to be changed, a variable value in a message is changed by calling an assignment function set _ para _ data:
s101, finding a corresponding variable in a variable value key value queue, and updating the variable value;
s102, querying a structure key value queue of the test message to obtain a signal corresponding to the variable, finding a corresponding signal value in the signal value key value queue, and updating the signal value;
s103, querying a structure key value queue of the test message to obtain a message corresponding to the signal, finding a corresponding message value in the message value key value queue, and updating the message value.
If the message needs to be sent, the message sending function send _ message _ data is called to realize that:
s201, searching a message Value key Value queue according to a required message to obtain a message Value;
s202, searching a structural key Value of the test message according to the required message, and acquiring hardware resource information bound by the message Value;
s203, sending the message to a specified service node, and calling the simulation hardware resource by the service node to send the simulation hardware resource to the tested product.
If the message needs to be received, the message is received by calling a receiving function recv _ message _ data:
s301, receiving a message of a tested product uploaded by a service node;
s302, searching a structural key value queue of the test message according to the identification of the received message to obtain a structure of the message, the signal and the variable corresponding to the message;
and S303, assigning the received message data to the corresponding message Value key Value queue, signal Value key Value queue and variable Value key Value queue respectively according to the structures of the obtained message, signal and variable.
If monitoring/displaying is needed, the monitoring/displaying function get _ para _ data is called to realize that:
s401, searching a structural key value queue of the test message according to the message needing to be displayed/monitored to obtain a corresponding message key, a signal key and a variable key;
s402, searching the corresponding message Value key Value queue, signal Value key Value queue and variable Value key Value queue according to the obtained message key, signal key and variable key, and pushing the obtained message, signal and variable Value to an interface for displaying/monitoring.
The following description is made with the pseudo code of two functions of set _ para _ data and send _ msg _ data:
Calling a keyword set _ para _ data (para _ name, value) to change a variable value in a message; the pseudo code of its execution logic is as follows:
If data needs to be transmitted (taking event type data transmission as an example temporarily), a key send _ msg _ data (msg _ name) is called, and the key needs to complete two steps: (1) acquiring the value of a corresponding message through the msg _ name; (2) and after the length, the bus information and the hardware channel information are acquired through the msg _ name, the message is issued. It executes pseudo code as follows:
the operation flow of the variable-based dynamic data operation and management system is shown in fig. 6:
1) A user selects a test data configuration file and a hardware resource configuration file of a current system to be tested and loads the test data configuration file and the hardware resource configuration file through an external interface module;
2) And the external interface module analyzes the test data configuration file and the hardware resource configuration file after judging that the test data configuration file and the hardware resource configuration file are correct, creates form data, and stores the tested product information, the test data structure information and the hardware information into the MySQL database.
3) And the simulation application tool extracts relevant information from the relational database through the external interface module to form an interactive interface for binding the test data and the hardware resources. And manually configuring the interface by a user, and binding the test data with the hardware channel. After the binding is finished, storing the binding result in a MySQL database;
4) The dynamic variable data management module initiates a register variable, extracts related information from the relational database, forms a dynamic data variable pool in the redis database and assigns initial values, namely a Value key Value queue of the test message and a structure key Value queue of the test message. (ii) a
5) When the variables need to be released, the key word function library of the external interface module accesses the dynamic data variable pool to obtain variable data, and then the test data is sent out through the release channel.
6) When the subscribed variables are updated, the external interface module calls the key word function library to update the variables of the dynamic data variable pool.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
