Description

Technical Field

[0001] The present invention relates to a multi-type and multi-structure interface test data generation system in the field of aerospace business systems, and is particularly suitable for dynamically configuring and generating interface test data of different types and structures between systems. Background Art

[0002] In the field of aerospace business systems, simulation tests of interface data of various types and structures are often required during system joint testing. Developers and testers need to build dedicated test data based on different interface types, interface structures, and interface information to complete the test. This type of test interface has many types and complex interface content. The customized development test program is not highly scalable. Interface changes will bring many unforeseen risks and duplication of work to system development, increasing development risks and costs. Summary of the Invention

[0006] The data layer includes the interface information model, data item information model and data item hierarchical model;

[0007] The interface information model is used to define the interface name, interface identifier, and interface type; interface types include XML, binary, and JSON types;

[0009] The data item hierarchical model is used to define the unique identifier of the interface information, the unique identifier of the data item information, the position offset of the data item, and the unique identifier of the parent node of the current data item.

[0021] Figure 1 It is a schematic diagram of the system architecture of the present invention. DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] The system architecture of the system for generating test data of multi-type and multi-structure interfaces between systems of the present invention is as follows: Figure 1 As shown, it is divided into three layers, including data layer, application service layer and presentation layer.

[0024] (1) Data layer

[0025] The data layer consists of the interface information model, the data item information model and the data item hierarchical relationship model, and is the basic data for the operation of upper-level software and components.

[0026] The interface information model is responsible for distinguishing interface types and defining interface names; the data item information model is responsible for the overall management of different types of data items; and the data item hierarchy model is responsible for defining the hierarchy of data items through a tree structure. The specific structure is as follows:

[0027] 1) Interface information model: unique identifier, interface name, interface identifier, interface type (including XML, binary, and JSON types);

[0028] 2) Data item information model: unique identifier, node form (including XML field, data frame byte array, JSON object and JSON array), data item value type (including numeric type, character type, Boolean type, floating point type, byte type and null type), data item default value, data item length;

[0029] 3) Data item hierarchical model: unique identifier, interface information unique identifier, data item information unique identifier, data item position offset, and unique identifier of the parent node of the current data item (when this item is empty, it means that the node is the root node).

[0030] (2) Application Service Layer

[0031] The application service layer consists of basic data configuration services, XML data generation services, binary data generation services, and JSON data generation services. These data generation services are based on the data layer's data model and utilize basic data configuration services to configure XML, binary, and JSON data models and generate various test data.

[0032] The basic data configuration service configures common data items and structural information based on XML, binary, and JSON interface data, and constructs an interface information model, a data item information model, and a data item hierarchy model, which are stored in the data layer. It also provides the ability to read data items and structural information, and can read specified interface information models, data item information models, and data item hierarchy models from the data layer. The XML-type data generation service and the JSON-type data generation service, based on different interface information models and the data item hierarchy model, combine the data item information in the data item information model to form a data structure entity, completing the generation of configuration-based XML and JSON-type interface test data. The binary-type data generation service, based on the interface information model, and information such as the data item length in the data item hierarchy model and the data item information model, completes configuration-based binary data generation, and uses a data generation algorithm to concatenate data items into byte arrays to generate binary structured data.

[0033] Specific process of XML type data generation service:

[0034] 1) Get all node information of an xml type interface. The data item node form is an xml field, and its collection is X field , and get the root node r of the xml interface, where r∈X field ;

[0035] 2) Define the method f(p,X field ) can get the child node set of the current node p where p∈X field ,

[0036] 3) Define the method To generate the XML structure based on the current node and node set, the following recursive relationship is included:

[0037]

[0038] 4) Get the root node and call g(r,f(r,X field )) method, in the recursive relationship, assigns values ​​to leaf nodes according to the data item value type and the default value of the data item to complete the XML data generation.

[0039] Specific process of binary data generation service:

[0040] 1) Get all node information of a binary interface. The data item node form is a data frame byte array. Let it be the set F frame ;

[0041] 2) In the data frame structure, the root node has no practical meaning, so traverse the set F frame, get the set F of all nodes that are leaf nodes (no child nodes) byte ;

[0042] 3) By traversing the set F byte , assign values ​​to leaf nodes according to the data item value type, the default value of the data item, and the length of the data item, and define node n as the data item in the data item hierarchical model, n∈F byte ;

[0043] 4) During the traversal process, the p(n,len) method is defined to pack binary data according to the position offset of the data item. len represents the traversal set F byte The total length of the data frame accumulated by the middle node completes the generation of binary data frame data.

[0044] Specific process of json type data generation service:

[0045] 1) Get all node information of a json type interface, the data item node form is json object or json array, set its collection to J field , and get the root node r of the json interface, where r∈J field ;

[0046] 2) Define the method f(p,J field ) can get the child node set of the current node p where p∈J field ,

[0047] 3) Define a node set The set J object Contains all data items whose node type is json object (JsonObject);

[0048] 4) Define node collection The set J array Contains all data items whose node type is json array (JsonArray);

[0049] 5) Define method g(r,J,function(r,r)) to generate a json structure based on the current node and node set, where r is a node. Function(r,r) is defined as follows: method h(r,k) adds a JsonObject type data item to the tree structure of the current root node r; method y(r,k) adds a JsonArray type data item to the tree structure of the current root node r, which contains the following recursive relationship:

[0050]

[0051] Represents the set of child nodes of the r node;

[0052] 6) Get the root node and call g(r,f(r,J field ),function(r,r)) method, in the recursive relationship, assigns values ​​to leaf nodes according to the data item value type and the default value of the data item to complete the json data generation.

[0053] (3) Presentation layer

[0054] The presentation layer consists of the interface information configuration service and the data generation and display service. The interface information configuration service dynamically completes the information configuration of a certain interface through the basic data configuration service. The steps are as follows:

[0055] 1) Read the data layer model based on the basic data configuration service, and complete the creation of the interface information model, data item information model, and data item hierarchical model in sequence;

[0056] 2) Configure interface details, including business data nodes and dynamically changeable type nodes, and configure corresponding default values, data item lengths, and other information based on the business;

[0057] 3) Complete the interface hierarchy tree configuration and clarify the tree structure relationship between nodes through dynamic dragging.

[0058] Through the above configuration, the interface content can be visually presented on the interface, showing the hierarchical relationship and specific content information of the interface content in a tree structure.

[0059] The data generation and display service is used to display the data entities generated by the XML type data generation service, the JSON type data generation service, and the binary type data generation service. It can display the specific interface content information, data item information, and the correctness of the generated interface test data through the interface.
