It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The data acquisition, storage, use, processing and the like in the technical scheme of the present disclosure all conform to the relevant regulations of the national laws and regulations.
Fig. 1 is a flow chart illustrating a method of generating test data according to a first embodiment of the present disclosure.
As shown in fig. 1, a method for generating test data according to a first embodiment of the present disclosure includes the following steps:
in step S101, metadata of a plurality of production fields included in production data is acquired.
It should be noted that, the execution subject of the test data generation method of the present disclosure is an electronic device. The method for generating test data according to the embodiment of the present disclosure may be performed by the apparatus for generating test data according to the embodiment of the present disclosure, and the apparatus for generating test data according to the embodiment of the present disclosure may be configured in any electronic device to perform the method for generating test data according to the embodiment of the present disclosure.
It should be noted that the production data includes a plurality of production fields. The production data and the production field are not limited too much, for example, the production data can comprise bank production data, insurance production data, hospital production data and the like, and the production field can comprise name, age, mailbox, mobile phone number, amount and the like.
It should be noted that different production fields may correspond to the same metadata, or may correspond to different metadata. Metadata is not overly restricted. For example, metadata may include a field name of a production field, a field category, a data format, a distribution of field values of the production field, and so forth.
The distribution of the field values of the production field may include statistics of the central tendency of the field values of the production field (such as mean, median, etc.), statistics of the degree of dispersion of the field values of the production field (such as variance, standard deviation, etc.), and statistics of the distribution form of the field values of the production field (such as bias coefficient, standard score, etc.).
In one embodiment, the metadata of the production field includes a field class of the production field. The metadata of a plurality of production fields included in the production data is obtained, wherein the metadata comprises field categories corresponding to target rules and determined to be field categories of the production fields if field values of the production fields meet the target rules in the rule set, or set categories are determined to be field categories of the production fields if the field values of the production fields do not meet each rule in the rule set. Therefore, whether the field value of the production field accords with any rule in the rule set can be identified, if so, the field category corresponding to the target rule is determined as the field category of the production field, and if not, the set category is determined as the field category of the production field.
It should be noted that, the rule set includes a plurality of rules, the target rule is any rule in the rule set, and a corresponding relationship between each rule in the rule set and the field category may be established in advance. The rule set and the set category are not excessively limited.
For example, the rule set includes rules 1 to 3, wherein a correspondence is provided between rule 1 and a field class mailbox, a correspondence is provided between rule 2 and a field class name, and a correspondence is provided between rule 3 and a field class phone number. The field class mailbox, the name and the mobile phone number are all constraint classes, and the set classes are non-constraint classes.
If the field value of the production field a accords with the rule 1, determining a field type mailbox corresponding to the rule 1 as the field type of the production field a.
If the field value of the production field b accords with the rule 2, determining the field category name corresponding to the rule 2 as the field category of the production field b.
If the field value of the production field c accords with the rule 3, determining the field type mobile phone number corresponding to the rule 3 as the field type of the production field c.
If the field values of the production field d do not meet the rules 1 to 3, determining the unconstrained category as the field category of the production field d.
In step S102, a generation requirement of the test data is acquired, and a plurality of test fields included in the test data are extracted from the generation requirement.
It should be noted that the generation requirement includes a plurality of test fields included in the test data. The generation requirement can be set by a developer and a user, and is not limited excessively, for example, the generation requirement can further comprise the total number of test data, the total number of field values of the test fields, the generation mode, the data format, the data source, the category of the data source and the like. The generating party may include batch generation, stream generation, and the like, and the data format may include JSON (JavaScript Object Notation, JS object numbered musical notation), XML (Extensible Markup Language ), CSV (common-Separated Values), and the like. It should be noted that JavaScript is a programming language.
It should be noted that, the related content of the test field may refer to the related content of the production field, which is not described herein.
In step S103, a production field corresponding to the test field is determined, and a rule for generating the test field is obtained based on metadata of the production field corresponding to the test field.
It should be noted that, the number of production fields corresponding to one test field may be at least one, for example, if the number of production fields is M, the number of production fields corresponding to one test field may be 1, 2 to M. Wherein M is a positive integer. The production fields corresponding to the different test fields may be the same or different.
In the embodiment of the disclosure, determining the production field corresponding to the test field may include the following several possible implementations:
mode 1, extracting a production field corresponding to a test field from a generation requirement.
In some examples, the generation requirement includes a correspondence between a test field and a production field. For example, the generating requirement includes a correspondence between the test field e and the production field a, and further includes a correspondence between the test field f and the production fields b and c, and further includes a correspondence between the test field g and the production field a, b, c, d, where the production field a corresponding to the test field e, the production fields b and c corresponding to the test field f, and the production field a, b, c, d corresponding to the test field g may be extracted from the generating requirement.
Therefore, the method can directly extract the production field corresponding to the test field from the generation requirement.
And 2, identifying that a target field exists in the plurality of production fields, wherein the field name of the target field is the same as the field name of the test field, and/or the field category of the target field is the same as the field category of the test field, and determining the target field as the production field corresponding to the test field.
For example, the field name of the production field a is SEGMENT2, the field type is mailbox, the field name of the production field b is SEGMENT3, the field type is mailbox, the field name of the production field c is SEGMENT4, the field type is mobile phone number, the field name of the test field e is SEGMENT2, the field type is mailbox, the field name of the test field f is SEGMENT5, and the field type is mobile phone number.
The field name of the production field a can be identified to be the same as the field name of the test field e, the field types of the production fields a and b are the same as the field type of the test field e, and the production fields a and b are determined to be the production fields corresponding to the test field e.
The field type of the production field c can be identified to be the same as the field type of the test field f, and the production field c is determined to be the production field corresponding to the test field f.
Thus, the method can determine the target field with the consistent field name and/or field category with the production field as the production field corresponding to the test field.
It should be noted that the rule for generating the test field is not limited too much, and may include, for example, a field type of the test field, a data type, a data format, a distribution of field values of the test field, and the like.
In one embodiment, the generating rule of the test field is obtained based on the metadata of the production field corresponding to the test field, and the generating rule of the test field is determined by the metadata of the production field corresponding to the test field.
For example, a field type of the production field c corresponding to the test field f may be determined as a field type of the test field f, a data type of the production field c may be determined as a data type of the test field f, a data format of the production field c may be determined as a data format of the test field f, and a distribution of field values of the production field c may be determined as a distribution of field values of the test field f.
In step S104, a plurality of field values of the test field are generated in accordance with the generation rule of the test field, and the plurality of field values of each test field are used as test data.
It should be noted that, according to the rule for generating the test field, generating the plurality of field values of the test field may be implemented by any data generating method in the related art, which is not limited herein. For example, the generation rule of the test field may be input into the data generation model, and a plurality of field values of the test field may be output by the data generation model.
In one embodiment, the method further comprises determining S data sources of the test data, performing format conversion on the test data according to the category of the t data sources to obtain t conversion data, and storing the t conversion data into the t data sources. Wherein S is a positive integer, and t is a positive integer not greater than S. Therefore, in the method, the format conversion can be carried out on the test data according to the type of the data source to obtain the conversion data, so that the conversion data is matched with the type of the data source.
In summary, according to the method for generating test data provided by the embodiment of the present disclosure, metadata of a plurality of production fields included in production data is obtained, a generation requirement of the test data is obtained, a plurality of test fields included in the test data are extracted from the generation requirement, a production field corresponding to the test field is determined, a generation rule of the test field is obtained based on the metadata of the production field corresponding to the test field, a plurality of field values of the test field are generated according to the generation rule of the test field, and a plurality of field values of each test field are used as the test data. Therefore, the production field corresponding to the test field can be determined, the metadata of the production field corresponding to the test field is considered to obtain the generation rule of the test field so as to generate a plurality of field values of the test field, and the test field with higher similarity with the production field can be obtained, namely, the test data with higher similarity with the production data can be obtained.
Fig. 2 is a flow chart of a method of generating test data according to a second embodiment of the present disclosure.
As shown in fig. 2, a method for generating test data according to a second embodiment of the present disclosure includes the following steps:
s201, metadata of a plurality of production fields included in the production data is acquired.
S202, obtaining the generation requirement of the test data, and extracting a plurality of test fields included in the test data from the generation requirement.
S203, determining a production field corresponding to the test field.
The relevant content of steps S201-S203 can be seen in the above embodiments, and will not be described here again.
S204, determining N value intervals of the production field corresponding to the test field as N value intervals of the test field.
In an embodiment of the present disclosure, metadata of a production field includes N valued intervals of a field value of the production field, where N is a positive integer. The generation rule of the test field comprises N value intervals of the test field.
In one embodiment, the metadata of the production field further includes a duty ratio of an ith value interval of field values of the production field, wherein the duty ratio of the ith value interval is a ratio between a number of field values within the ith value interval and a total number of field values of the production field, i being a positive integer not greater than N.
The method comprises the steps of obtaining a generation rule of a test field based on metadata of a production field corresponding to the test field, and determining the duty ratio of an ith value interval of the production field corresponding to the test field as the duty ratio of a jth value interval of the test field, wherein the ith value interval is identical to the jth value interval, the duty ratio of the jth value interval is a ratio between the number of field values in the jth value interval and the total number of field values of the test field, and both i and j are positive integers not larger than N. It is understood that the rule for generating the test field includes the duty ratio of N valued intervals of the test field. Therefore, the method can determine the duty ratio of the value interval of the production field corresponding to the test field as the duty ratio of the value interval of the test field, so that the duty ratio of the value interval of the test field is similar to the duty ratio of the value interval of the production field, and the method is beneficial to obtaining the test field with higher similarity with the production field.
For example, if the field type of the production field c corresponding to the test field f is a name, the value interval of the field value of the production field c may include a surname, a limp name, and a rare word surname, if the total number of the field values of the production field c is 100, the number of the field values of the surname of the production field c is 20, the number of the field values of the limp name of the production field c is 10, the number of the field values of the rare word surname of the production field c is 1, the ratio of the surname of the production field c is 20%, the ratio of the limp surname is 10%, and the ratio of the rare word surname is 1%.
The surname, the prune surname and the uncommon surname can be determined as the value interval of the test field f, 20% is determined as the duty ratio of the surname of the test field f, 10% is determined as the duty ratio of the prune surname of the test field f, and 1% is determined as the duty ratio of the uncommon surname of the test field f.
For example, if the field type of the production field c corresponding to the test field f is an amount, the value interval of the field value of the production field c may include (0, 100), (100, 200), (200, 300), (300, 400), and if the field value of the production field c is 100, the number of field values in (0, 100) of the production field c is 10, the number of field values in (100, 200) of the production field c is 50, the number of field values in (200, 300) of the production field c is 30, and the number of field values in (300, 400) of the production field c is 20, the (0, 100) of the production field c accounts for 10%, the (100, 200) accounts for 50%, the (200, 300) accounts for 30%, and the (300, 400) accounts for 20%.
(0, 100], (100, 200], (200, 300], (300, 400) may be determined as the value interval of the test field f, and 10% may be determined as the duty ratio of (0, 100) of the test field f, 50% may be determined as the duty ratio of (100, 200) of the test field f, 30% may be determined as the duty ratio of (200, 300) of the test field f, and 20% may be determined as the duty ratio of (300, 400) of the test field f.
S205, generating a plurality of field values of the test fields according to the generation rule of the test fields, and taking the field values of each test field as test data.
The relevant content of step S205 may be referred to the above embodiments, and will not be described herein.
In summary, according to the method for generating test data provided by the embodiment of the present disclosure, N value intervals of a production field corresponding to a test field may be determined as N value intervals of the test field, so that the value intervals of the test field are similar to the value intervals of the production field, which is helpful to obtain a test field with higher similarity to the production field.

S301, metadata of a plurality of production fields included in production data is acquired.
S302, obtaining the generation requirement of the test data, and extracting a plurality of test fields included in the test data from the generation requirement.
S303, determining a production field corresponding to the test field.
The relevant content of steps S301 to S303 can be seen in the above embodiments, and will not be described here again.
S304, determining the duty ratio of the production field corresponding to the test field as the duty ratio of the test field, wherein the duty ratio of the test field is the ratio between the total number of field values of the test field and the total number of test data.
In an embodiment of the present disclosure, the metadata of the production field includes a duty cycle of the production field, wherein the duty cycle of the production field is a ratio between a total number of field values of the production field and a total number of production data. The generation rule of the test field includes a duty cycle of the test field.
In one embodiment, the generating rule of the test field is obtained based on metadata of a production field corresponding to the test field, and the generating rule further comprises extracting total amount of test data from the generating requirement, and determining a product between a duty ratio of the test field and the total amount of the test data as total amount of field values of the test field. It will be appreciated that the generation rule of the test field includes the total number of field values of the test field. Thus, the product between the duty cycle of the test field and the total number of test data may be determined as the total number of field values of the test field in the method.

In some examples, determining the product of the duty cycle of the j-th value interval of the test field and the total number of field values of the test field as the number of field values within the j-th value interval of the test field is further included.
For example, if the total number of field values of the test field f is 1000, the value interval of the test field f includes (0, 100), (100, 200), (200, 300), (300, 400), and the ratio of (0, 100) of the test field f is 10%, the ratio of (100, 200) is 50%, the ratio of (200, 300) is 30%, and the ratio of (300, 400) is 20%.
The product 100 of 10% and 1000 may be determined as the number of field values within (0, 100) of the test field f, the product 500 of 50% and 1000 may be determined as the number of field values within (100, 200) of the test field f, the product 300 of 30% and 1000 may be determined as the number of field values within (200, 300) of the test field f, and the product 200 of 20% and 1000 may be determined as the number of field values within (300, 400) of the test field f.
