Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations or operations have not been shown or described in detail to avoid obscuring aspects of the invention.
The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.
The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
The "recommendation system" described in this embodiment may be a recommendation module of a friend-making application product, and is generally used to dynamically push information that may be of interest to a current user. For example, the recommender system (e.g., a recommender module of a friend-making application) pushes N recommenders and their dynamics to the current user this time (where N is a positive integer), and the recommender system pushes N different recommenders and their dynamics to the user next time. Therefore, if the recommenders are tested one by one, the problems of huge testing workload and huge cost caused by manual query of a large amount of user information are caused. Meanwhile, the randomness of the recommendation causes that manual testing cannot ensure the testing accuracy.
In addition, because the recommendation system dynamically recommends different information, the way of testing through forged data is also not suitable for testing the recommendation system of friend-making application products.
Fig. 1 shows a flow diagram of a method for testing a recommendation system according to an embodiment of the invention. The test method of the recommendation system provided by the embodiment overcomes the above disadvantages of the test method of the existing recommendation system at least to some extent.
The execution subject of the test method of the recommendation system provided in this embodiment may be a device having a calculation processing function, such as a server.

and step S103, testing the information to be tested through the standard range value of the parameter to be tested.
In the technical solution provided in the embodiment shown in fig. 1, on one hand, a parameter to be tested is obtained to determine a standard range value of the parameter to be tested, and then the information to be tested output by the recommendation system is tested according to the standard range value of the parameter to be tested, so that the test on the recommendation system is completed according to the test result. Compared with the problem of low test accuracy caused by the existing manual test mode, the test accuracy is improved by automatically inquiring and counting the to-be-tested information output by the recommendation system in the embodiment. Meanwhile, the problem of high overhead caused by manual testing of the dynamically recommended information to be tested is solved.
On the other hand, the information to be tested is further determined according to the identifier of the recommender and the parameter to be tested by acquiring the identifier of the recommender output by the recommendation system. Therefore, the information to be tested can be rapidly and accurately determined, the problem of low testing efficiency caused by redundancy of the information to be tested is effectively avoided, and the testing efficiency is improved.
Specific embodiments of the individual steps of the embodiment shown in FIG. 1 are described in detail below.
In an exemplary embodiment, fig. 2 schematically shows a flowchart of a method for determining a standard range value of a parameter to be measured according to an embodiment of the present invention, which may be used to explain a specific implementation manner of step S101.
Referring to fig. 2, the method for determining the standard range value of the parameter to be measured according to the embodiment includes:
step S201, acquiring a recommendation requirement set by a user, and determining a parameter to be measured according to the recommendation requirement; and step S202, determining a standard range value of the parameter to be measured according to the recommendation requirement and the parameter to be measured.
In an exemplary embodiment, if the recommendation set by the user is "please recommend me a single man with an age between 20 and 30 years, a height between 170 and 185 centimeters, a master and above academic degree, and a residence in Beijing". In order to recommend a user (recommender) meeting the set recommendation requirement to the user, in the technical solution provided in this embodiment, the following keywords may be extracted from the recommendation requirement set by the user in a keyword extraction manner: age, height, school calendar, residence and gender, so as to determine the parameters to be tested related to the test of the recommendation system according to the keywords.
In an exemplary embodiment, the recommendation requirement is filtered again according to the parameters to be measured determined in the above steps, and a range value (standard range value) corresponding to each parameter to be measured is determined. For example, if the parameter "height" to be measured, the recommendation requirement is screened by the keyword "height", and the standard range value is obtained as follows: between 170 cm and 185 cm. In the following test process, aiming at a certain parameter to be tested, the corresponding information to be tested is compared with the standard range value to realize the test of the recommendation system.
In an exemplary embodiment, after the parameter to be tested and the standard range value thereof are determined, the number of the test combinations is also determined by traversing the parameter to be tested and the standard range value thereof. Illustratively, for the parameter "age" to be measured, the standard range value is 18 to 60 years, but the number of test combinations regarding the parameter "age" to be measured can be determined to be 5. Specifically, the test combination of the parameter "age" to be measured is as follows: testing the upper limit: greater than 18 years old, without upper limit; testing the lower limit: less than 60 years old, no lower limit; testing an upper limit and a lower limit simultaneously: greater than 18 and less than 60; fourthly, the first boundary value is tested to be less than 18; second boundary value test, greater than 60. It can be seen that the number of test combinations for the parameter "age" to be measured is 5 in total.
In an exemplary embodiment, the parameters to be measured are determined with respect to recommended requirements set by a user a of an application product. The standard range values of the parameters to be tested and the number of the test combinations of each parameter to be tested can be referred to table 1.
TABLE 1
In an exemplary embodiment, in the case that the parameter to be measured is greater than one, the total number of parameter combinations may be determined according to the following two ways.
The first mode is a cadier mode, specifically, the number of test combinations corresponding to each parameter to be tested is multiplied, and the product is used as the total number of the parameter combinations. If the number of the test combinations of the parameter to be tested, namely the age, is 5, the number of the test combinations of the parameter to be tested, namely the living area, is 10, the number of the test combinations of the parameter to be tested, namely the height, is 5, the number of the test combinations of the parameter to be tested, namely the academic calendar, is 5, and the number of the test combinations of the parameter to be tested, namely the monthly income is 6, the total number of the corresponding test combinations is as follows: 5 × 10 × 5 × 6 ═ 9000 test combinations.
The second approach is a simplification of the first approach. In view of the fact that the relationships among the parameters to be tested are independent and independent, an independent testing mode can be adopted. Namely, the total number of the test combinations is determined by means of summation: 5+10+5+5+6 are 31 kinds.
In an exemplary embodiment, in the case that the parameter to be measured is more than one, determining the total number of parameter combinations is not limited to the above two ways.
Taking the second method as an example, the 31 test combination forms are stored in a table, and then the 31 test combination forms are traversed and filled in the parameters of the data driving interface to be tested, so that the test taking the 31 test combination forms as the input can be automatically completed.
Illustratively, the unit test framework of python may be utilized to do the driving of data. Storing the data in an excel table, reading out the data line by line, and then calling an interface to execute testing by cycle.
In the technical solution provided by the embodiment shown in fig. 2, the data-driven test is used for testing an application product including a recommended user function, so that the problem of low test efficiency caused by repeated manual tests is solved, meanwhile, the test overhead is saved, and the test accuracy is favorably provided.
In an exemplary embodiment, fig. 3 schematically shows a flowchart of a method for determining information to be measured according to an embodiment of the present invention, which may be used to explain a specific implementation manner of step S102.
Referring to fig. 3, the method for determining information to be measured provided in this embodiment includes:
step S301, creating a class related to recommender information, and taking the parameter to be tested as the attribute of the class; step S302, obtaining the identifier of the recommender from the output data of the recommendation system, and initializing the class through the identifier to determine the recommender instance; and step S303, acquiring the attribute value of the recommender instance as the information to be tested from the database.
In an exemplary embodiment, a class related to recommender information is created in step S301, and the parameter to be measured is taken as an attribute of the class. The embodiment adopts a result data mode to improve the extraction accuracy of the information to be detected.
In an exemplary embodiment, the output data of the recommendation system is in JSON format. Then item _ id can be obtained from the output data in JSON format to obtain the identity of the recommender.
Specifically, the identification of the recommender is extracted:
in order to reduce information redundancy and accurately determine the information to be detected, the identifier ID of the recommender is extracted first in this embodiment for subsequent information arrangement. Specifically, all item _ IDs in the JSON can be read by the ID extraction module and stored in an array for use by subsequent modules.
For example, in the step S302, the class is initialized according to the obtained identifier of the recommender to determine the recommender instance. Further, the information about the parameter to be tested is obtained from the database and is used as the attribute value of the recommender instance, and then the information to be tested of the test is determined.
And extracting recommender information:
the recommender information extraction module is mainly used for extracting the information of the user for statistics and verification of subsequent results. The basic user information that we need statistics is probably as follows: age, sex, place of birth, income, school calendar, height, weight, native place, etc.
In the technical solution provided by the embodiment shown in fig. 3, all recommended information is extracted to avoid manual query one by one, thereby improving the testing efficiency and reducing the manual overhead.
In an exemplary embodiment, fig. 4 schematically shows a flowchart of a data-driven testing method according to another embodiment of the present invention, which may be used to explain a specific implementation manner of step S103.
Referring to fig. 4, the data-driven testing method provided by this embodiment includes:
step S401, counting the information to be tested, and determining the range value to be tested of the parameter to be tested, including: an upper limit value to be measured and a lower limit value to be measured; and step S402, testing the range value to be tested through the standard range value of the parameter to be tested.
In an exemplary embodiment, the information to be tested is counted in step S401, and the parameter "age" to be tested is taken as an example for explanation. For the user B, obtaining and counting recommender information recommended by the recommendation system for 4 times, wherein the specific statistical result of each time is as follows:
the statistical result of the recommender information recommended for the first time is as follows: the range value to be measured: 26-41 years old, the upper limit value to be detected is 41 years old, and the lower limit value to be detected is 26 years old;
and the statistical result of the recommender information recommended for the second time is as follows: the range value to be measured: 23-40 years old, the upper limit value to be tested is 40 years old, and the lower limit value to be tested is 23 years old;
and the statistical result of the third recommended recommender information is as follows: the range value to be measured: 24-41 years old, the upper limit value to be detected is 41 years old, and the lower limit value to be detected is 24 years old;
the statistical result of the recommender information recommended for the fourth time is as follows: the range value to be measured: 26-39 years old, the upper limit value to be measured is 39 years old, and the lower limit value to be measured is 26 years old.
Among the recommendation requests set by the user B, the information "age" to be measured is set to 25 to 40 years old. Whether the recommender information meets the recommendation of the user is verified in the following steps, that is, fig. 5 is used to explain how to judge whether the age of the recommender is 25-40 years old.
In an exemplary embodiment, fig. 5 schematically shows a flowchart of a data-driven testing method according to still another embodiment of the present invention, which may be used to explain a specific implementation manner of step S402.
Referring to fig. 5, the data-driven testing method provided by this embodiment includes:
step S501, judging whether the upper limit value to be detected and the lower limit value to be detected are both within the standard range value;
in an exemplary embodiment, in response to that the upper limit value to be measured or the lower limit value to be measured is not within the standard range value, step S502 is executed: the result of the data drive is determined to be a throw error.
Illustratively, the upper limit value to be measured in the statistical result of the recommender information recommended for the first time/the third time exceeds the standard range value, and the lower limit value to be measured in the statistical result of the recommender information recommended for the second time exceeds the standard range value. That is, the first, second and third cases are that the upper or lower boundary is out of range, so that the recommended user does not meet the recommendation of user B, thereby determining that the data-driven result is a throw error.
In an exemplary embodiment, in response to that the upper limit value to be measured and the lower limit value to be measured are both within the standard range value, for example, the statistical result of the recommender information recommended for the fourth time is that the standard range value does not completely cover the range value to be measured, which may be that the range setting in the code to be measured is problematic, and may also be caused by insufficient data fetching.
Step S503 is executed: acquiring output data of the recommendation system to expand the information to be tested, and updating a range value to be tested according to the expanded information to be tested; and, step S504: and testing again according to the updated range value to be tested.
In an exemplary embodiment, the output data of the recommendation system (i.e., the recommender information of the user B) may be continuously collected to expand the information to be tested, and the specific method for expanding the information to be tested may refer to the specific implementation manner provided in the embodiment shown in fig. 3, which is not described herein again.
In an exemplary embodiment, the specific method for updating the value of the range to be measured through the expanded information to be measured may refer to the specific implementation manner provided in the embodiment shown in step S401, and is not described herein again.
In an exemplary embodiment, the specific method for performing the test again according to the updated value of the range to be tested may refer to the specific implementation manner provided in the embodiment shown in step S402, and is not described herein again.
In the technical solutions provided by the embodiments shown in fig. 4 and 5, the accuracy of the test is improved by performing automatic query statistics on the information to be tested output by the recommendation system. Meanwhile, the problem of high cost caused by manual test of the dynamically recommended information to be tested is solved.
