s1, defining at least one data generation rule in the database for at least one data type.
The database includes data for enumerated values for each data type (e.g., nationality, marital), as well as various summaries of the generated data. Such as contract information, whose enumerated value data includes nationality, marital, house property, and the like, which are involved in the house property business system. For example, enumerated values corresponding to nationality include: mainland china, hong kong and ao tai, foreign nationality; enumerated values for marital correspondences include: married, not married, bereaved, dissimilarity; enumerated values for the property of the house include: commercial houses, purchased public houses, economically applicable houses, removal and placement houses and house change houses. The database supports direct use of generated data, for example, a plurality of different contract information are constructed for the same seller, and the various information of personnel are mutually related and can be directly used.
Defining at least one data generation rule for at least one data type, wherein personnel information comprises an identity card number, nationality and marital information, the identity card number is defined to be 18 bits long, the 7 th to 10 th identification year and the 17 th identification gender; enumerated values defining nationality and marital are obtained from a database. For example, the house information includes the name of the building, the year of construction and the property of the house, and the name of the building is defined to be randomly acquired from the database; defining numbers between the established year random assignments 2000-2010; the defined house property is obtained from the corresponding enumerated value in the database.
S2, acquiring and analyzing the service process information of the system to be tested to obtain the data type of the service process.
The system to be tested, such as an NTS transaction system, a configuration platform system and other internal systems needing to construct test data. For example, contract information of the service flow of the NTS transaction system is acquired, and the contract information is analyzed to obtain the property (data type) of the house.
In this step, information of each service flow of the system to be tested can be obtained and analyzed, and the data type of each service flow is obtained. The data type required by the first process of the system to be tested is obtained through analysis, and then the data type required by the second process is automatically analyzed, so that the data type of each service process is obtained in sequence.
And S3, acquiring the data generation rule matched with the data type from the database, and automatically generating test data according to the matched data generation rule.

And acquiring a rule set matched with the data type from the database, and automatically generating test data according to the matched rule set. For example, the data type is an identification number, and a plurality of generation rules are defined, for example, a first rule: replacing the data of the identification year in the randomly acquired identity card number with a random year in 1950-2000; the second rule is as follows: the data identifying the sex in the randomly acquired identification number is changed to be odd (representing a male) or even (representing a female). And when the test data is automatically generated, matching the first rule with the second rule, and correspondingly replacing and changing the data for identifying the year and the sex in the identification number.
Optionally, before automatically generating the test data, it is determined whether the data type is an associated data type, where the associated data type has one or more associated data types. If the data type is the associated data type, automatically generating the test data of the associated data type and the test data of one or more data types associated with the associated data type according to the matched data generation rule. For example, the data type of "buyer property" (data value includes individual and company) in the contract information, when the acquired data value is "individual", the personal information (including buyer name, gender, marital, contact address, nationality, etc.) in the "buyer information" data type (composite data type) is associated, and the personal information is automatically generated; when the acquired data value is 'company', company information (including company name, company registration address, company certificate number, company legal name, company legal nationality, company legal identity number and the like) in the 'buyer information' data type is associated, and the company information is automatically generated.
