And the server side service instance MockServer generating module is used for simulating a function interface to return parameter values by using a description file of the service description model for testing according to the frame code of the new model to generate the server side service instance MockServer. If the service description model is tested, the description file (such as an IDL file) of the service description model to be tested can be used as the description file of the service description model for testing; if the data object model is tested, the description file of the service description model used for testing may be a description file of any given one of the service description models, and the data object model may be described.
The client capability test MockClient generation module is used for loading an interface by using a Java parent class loader according to a frame code of a service instance of a server so as to acquire a class object instance by using a reflection mechanism, collecting interface method array information of a service description model for testing by using the reflection mechanism, acquiring an instance class required by a client through the reflection mechanism according to the acquired class object instance and interface method data information, creating a client object by using the instance class and acquiring member variables and corresponding calling methods to form the client capability test MockClient.

The standard data elements, the entity data model and the service description model can be in tree structures, can be uniformly stored in a database with field attributes and precision, can provide the standard and definition of basic data elements of a consistent service system, and is the basis for establishing all models. The entity data topic model (data object model) is stored as a wide table (the wide table is a database table with more fields in a literal sense) of a data object oriented to a specific business system, generally refers to a database table with related indexes, dimensions and attributes of business topics associated together, and refers to a model which is packaged in a structure called an object class in a mode of the attributes and the operation attributes of data resources, and is essentially abstract description of the business data resources; the service description model is stored as an interface description file of interface interaction between various service systems defined by a system in a specific service field, and the input and output parameter sources of the interface are standard data elements or complex entity data models.
The model building layer can be responsible for building standard data elements (obtained by importing or manually adding), a solid data model (related to an interaction mode) and a service description model, provides a visual interface, builds a new data model or a service description model by adopting a dragging and associating mode, and supports two modes of building a data object and building a new data model based on the existing model aggregation. Selection, such as checking selection, can be made on the interface for the function interface model, basic type of function, container, etc.

(S12) lexical analysis and verification are carried out on the text file generated by using the data entity object model and the function interface model described in the language in the step (S11), the constructed description file is scanned by taking characters as units, blank symbols, line feed symbols and annotation parts are skipped, if the scanned words are keywords of the description language, attribute codes (such as types, structures, functions, parameter numbers, data objects and the like, such as int types, are changed into i32) corresponding to the reserved words are returned, otherwise, character string information of the words is directly returned until the end of the description file is scanned, and the lexical analysis and verification on the description file are completed;
(S13) parsing the description file (i.e., IDL description file) (to obtain a file recognizable by the compiler) according to the result of the lexical analysis of the step (S12), initializing a global variable to call and generate a code function generating code according to execution of a corresponding function, parsing a language type, generating a corresponding class object according to the language type, and then calling the generating program function to generate a corresponding program code; there may be a corresponding table of attribute codes and corresponding contents, and the obtained attribute codes may be parsed into files that a compiler can recognize, and the compiler is also a compiler through proper adjustment;
