[0035] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following will briefly introduce the accompanying drawings required for the description of the embodiments of the present application.

[0040] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present invention.

[0041] Those skilled in the art of the present technology can understand that, unless specifically stated otherwise, the singular forms "a", "an", "the", and "said" used herein may also include the plural forms. The "first", "second", etc. are only used to clearly introduce the solution and define the objects, and do not limit the objects themselves. Of course, the objects defined by "first" and "second" may be the same terminal, device, and user, etc., or the same type of terminal, device, and user. It should be further understood that the term "including" used in the description of the present application means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or their groups. The phrase "and / or" used herein includes all or any unit and all combinations of one or more of the associated listed items.

[0042] In addition, it should be understood that "at least one" in the embodiments of the present application means one or more, and "a plurality" means two or more. The "and / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B may be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item) of the following" or its similar expression refers to any combination of these items, including any combination of single item (s) or plural item (s). For example, at least one (item) of a, b, or c may represent: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c may be single or multiple.

[0043] As stated in the background art, currently in many testing fields including financial testing, etc., test data requires testers to obtain the test data by using a database or other auxiliary generation operations. This method has cumbersome steps and high labor costs. In addition, there are also some technical solutions that first determine the data generation models corresponding to each test system, and then generate the test data corresponding to each test system based on the key data generation fields and data generation rules in each data generation model. The test data generated by this method is fixed and cannot generate diverse test data according to scenario changes. Additionally, there are some solutions that obtain the corresponding driver functions in the database operation function library by parsing and executing SQL instruction information, and obtain the parameterization basis from the target database. This method is mainly used for automated test scripts and uses pure technical languages, which are not easy to understand and operate. There are also some solutions that create generation rules for each test field type in advance and convert the original data in the database into multiple test data. This method uses pure technical languages, and testers need to have a relatively in-depth understanding of the generation rules to accurately write the corresponding statements, which is not conducive to popularization and use. In summary, based on the various limitations of the above test data acquisition solutions, the following embodiments of the present application disclose a data acquisition method and device to solve at least one of the above technical problems.

[0044] Figure 1 FIG. shows a schematic flowchart of a data acquisition provided by an embodiment of the present application. As Figure 1 shown, the method mainly may include:

[0045] S101. Obtain a test case input by a tester and identify business elements;

[0046] S102. Obtain business data having a mapping relationship with the business elements from a pre-constructed business data model according to the business elements; wherein the business data model stores business elements and business data having a mapping relationship with the business elements.

[0047] In a further optional embodiment, the constructing the business data model includes:

[0048] Step 1. Obtain valid business data;

[0049] Step 2. Construct the valid business data model based on a tree model through a business data hierarchical division standard; wherein the business data model includes at least a parent class, a subclass, a detailed class, and derivative business data in a descending order.

[0050] In a preferred embodiment, the constructing the business data model includes:

[0051] Step 1. Obtain the data source of the system database table;

[0052] Step 2: Clean the dirty data in the data source, and filter out the data irrelevant to the business elements to obtain the effective business data.

[0053] Step 3: Based on the business data hierarchy division standard, construct the effective business data model based on the tree model; wherein the business data model includes at least, in descending order, parent classes, subclasses, detailed classes, and derivative business data.

[0054] In a further alternative embodiment, the business element values correspond to the enumerated values of the business data, including fixed values, function relation values, or SQL rule values, that is, the business data having a mapping relationship with the business elements can be:

[0055] (1) Fixed values;

[0056] (2) Function relations;

[0057] (3) SQL rules for obtaining the business data having a mapping relationship with the business elements in the database table.

[0058] In a further alternative embodiment, the obtaining of the business data having a mapping relationship with the business elements includes:

[0059] Step 1: Obtain the business fields in the pre-constructed business data model according to the business elements; wherein the business fields are the unique identifiers of the business data having a mapping relationship with the business elements;

[0060] Step 2: Determine the business data having a mapping relationship with the business elements according to the unique identifier.

[0061] In the embodiments of the present application, each business element included in each business transaction (that is, the business elements included in the test cases) can correspond to the business data having a mapping relationship with it, and the business data can be corresponding through the library table and the library table fields. For example, for the customer class - the private customer class - the private customer class with a normal account status, the business data it contains are customer number cust_info - cust_no, customer name cust_info - cust_name, customer document type cust_info - cust_IDtype, etc. For the business transaction APICODE, its business elements are customer number, customer name, customer document number, account number, etc., and among them, the customer number, customer name, and customer document number correspond to the business data of each specific business field in the above business data. Therefore, by establishing the mapping relationship between the business elements and the business data, a bridge for converting the business language to the technical language can be established.

[0062] Based on the above embodiments, in a specific embodiment, testers provide test cases or build business elements by means of checking / filling in the business values of the business scenarios through the interface. The system can automatically fill in the general SQL rules according to the established business data model or supplement them in multiple ways with fixed values and function relationship values to convert business language into technical language. The specific implementation method is as follows:

[0063] Each business transaction has many transaction scenarios, but the business elements, that is, the business language, used in these transaction scenarios are the same, only the values are different. Combining the established business data model (in a specific embodiment, this model is stored in the form of business element - business data table), only the SQL filling of the general value-taking method with the enumerated values of the business elements or the supplementation in multiple ways with fixed values and function relationship values is required to complete the adaptation of the business scenario of the technical language. As Figure 2 shown in the example, by changing the enumerated values of the general SQL rules, the data conditions of different scenarios can be satisfied, and the conversion from business language to technical language can be realized.

[0064] In a further optional embodiment, when the business data having a mapping relationship with the business element can be the SQL rule for obtaining the business data having a mapping relationship with the business element in the database table, the implementation manner of obtaining the business data having a mapping relationship according to the business element further includes:

[0065] Step 1: Construct a unique identification number for the business data of the target test case; wherein, the target test case includes at least two or more business elements; the identification numbers of the business data obtained according to the two business elements are both the unique identification number;

[0066] Step 2: Cache the first business data of the first business element obtained in the business scenario data pool;

[0067] Step 3: Obtain the second business data in the pre-constructed business data model according to the first business data and the second business element.

[0068] In the embodiment of the present application, a business scenario data pool (i.e., a test scenario data pool of a business test case) is established, and real-time dynamic interaction of business scenario-related elements is performed with a unique identification number to obtain a set of data that meets the scenario. For example, a business scenario case includes business elements A, B, C, D..., where the values ​​of A and B are obtained by a joint table SQL, and the SQL relationship of B is partially determined by the value of A. Then, the invention will preferentially obtain the value of A according to the SQL of A, store it in the business scenario data pool, and generate a unique scenario identification number. Then, the value of A is passed into the SQL rule of B to obtain the value of B, and then written into the scenario under the business scenario class identification, and so on to complete the acquisition of a set of scenario business data. Based on the embodiment of the present application, the difficulties and pain points of dynamic acquisition of test data are solved, such as high difficulty and low efficiency, insufficient diversity of test data and low accuracy.

[0069] Based on the data acquisition scheme provided by the above embodiment of the present application, in specific application operations, users only need to select and configure relevant data classes in the interface according to the business scenario to obtain corresponding test data, without paying attention to the value logic of the data class or business scenario, thereby improving user experience, lowering the threshold for use, and greatly improving test efficiency; in addition, the data acquisition scheme provided by the above embodiment can also meet the user's 7*24 hours real-time dynamic acquisition of test data needs, and the acquired test data is dynamic and diverse, enriching the test scenario while avoiding the possible insufficiency of manual testing. At the same time, using the data acquisition scheme disclosed in the above embodiment of the present application, when a major functional or architectural change occurs in the business system, it is only necessary to maintain the data relationship model of the affected data class and business library table in a targeted manner to complete the update of test data in real time. Users are not aware of it and do not need to be aware of it at the business level, which greatly improves the ease of use and robustness of the test data acquisition scheme.

[0074] The 301 acquisition module is further configured to obtain business data having a mapping relationship with the business element from a pre-constructed business data model according to the business element.

[0075] In a further embodiment, according to the valid business data obtained by the 301 acquisition module, the 303 construction module is specifically configured to construct the business data model based on a tree model through a business data hierarchy division criterion; wherein the business data model includes at least a parent class, a subclass, a detailed class, and derivative business data in a descending order.
