All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In one embodiment, as shown in fig. 1, a sample generation method for automated testing is provided, wherein the sample for automated testing is taken as an example of air ticket data testing, but is not limited thereto; the sample generation method for the automatic test comprises the following steps:
s1: acquiring a data source based on user search behaviors, wherein the data source comprises route information with flight date and department; the airline department includes an independent airline and a common airline.
The data source is the data source of the test case, and the closer the data source is to the data input by the user in the real application, the better the coverage and representativeness of the test sample established according to the data source is, and the better the test effect can reflect the problems of the tested system/module.
The user searching behavior refers to that the user searches through the web, APP and other modes, for example, the user searches for tickets, air tickets, flight information, and searches for gourmet and tourist attractions.
Specifically, the data source comprises a departure place, a destination, a departure date and a navigation code based on user search; the method comprises the steps of collecting an air ticket searching log, cleaning data, and recording a departure place, a destination, a departure date and a navigation department code when a user searches an air ticket to obtain airline information with flight dates and navigation departments, wherein each navigation department comprises a unique airline and/or an airline shared with other navigation departments, so that a data source based on user searching behaviors is formed and is used as a main data source of a test case.
S2: and grouping the data sources according to the flight date to obtain first-level hierarchical sampling data.
Specifically, data are layered according to dates, the data coverage rate of the approaching and hot dates is high through a reasonable sampling rate, meanwhile, the omission of routes of the long-term and cold dates is avoided, and a certain coverage proportion is given. For example, the groups are divided into "within 3 days", "3 to 7 days", "7 to 15 days", "15 to 30 days", "30 to 90 days", and "departure route after 90 days", etc.
S3: and screening the first-level hierarchical sampling data according to the affiliated driver to obtain second-level hierarchical sampling data.
The amount of routes is also distributed unevenly due to the fact that the routes of different navigation departments are different; therefore, each navigation department should theoretically cover as much as possible, and the navigation departments are layered, so that each navigation department can be covered.
Specifically, a sample is selected on the basis of the first-level hierarchical sampling data, and the sample can cover all navigation departments, so that the second-level hierarchical sampling data is obtained.
S4: and screening the second-level hierarchical sampling data by using the independent air route and the common air route to obtain third-level hierarchical sampling data.
After step S3, some navigation systems have unique routes, and the data volume is often a low proportion of the total volume; but the unique air route is more important, so that the data of the unique air route of the screening department is added to improve the sample coverage ratio of the unique air route.
Specifically, the method is divided into two types according to the unique route and the common route of the navigation department, and third-level layered sampling data is formed.
S5: and performing sample extraction on the third-level hierarchical sampling data through a first preset weighted random sampling method to obtain a test case data set based on user search behaviors.
The first preset weighted random sampling method is used for weighting the third-level hierarchical sampling data and then sampling, so that a test case data set based on user search behaviors is obtained.
In the embodiment, the test data is divided into three layers according to the date, the driver, the unique route and the common route, and the test data is extracted by adopting a weighted random sampling algorithm in the third layer, so that the coverage and representativeness of the finally obtained test case data set based on the user search behavior are better than those of a mode of selecting samples by simple sampling, and the automatic test effect is improved.
Further, regarding step S4, that is, performing sample extraction on the third-level hierarchical sampling data by using a first preset weighted random sampling method, the method specifically includes the following steps:
s41: and taking the times of searching the route information by the user as the weight, and sequencing the route information in the third-level hierarchical sampling data from large to small according to the weight.
The airline information includes departure place, destination, departure time, driver code, etc., and the more times the airline information is searched by the user, the more important the airline is represented, and the larger the weight occupied.
Specifically, a route information set X = [ X1, X2, X3,.. once.. Xn ] is included in the third-level hierarchical sampling data, where n is a total number of routes, and the ith route information Xi (including a starting place, a destination, and a travel date) is searched by the user for Wi times, that is, the weight is Wi. Then, the above-mentioned X1 to Xn are arranged from large to small according to the magnitude relation of Wi.
S42: and calculating the sum of the weights of all the route information.
Specifically, the sum of the weights sum of all the routes X1 to Xn is calculated:
Figure 183509DEST_PATH_IMAGE002
s43: and randomly generating a random number, wherein the random number is between 1 and the sum of the weights.
Specifically, a random number R is generated by a random algorithm before 1 to sum, that is,
Figure 291143DEST_PATH_IMAGE004
wherein random is a random number acquisition function for randomly selecting a number between 1 and sum.
S44: and accumulating the weight of the sequenced route information until the weight is larger than or equal to the random number, and taking the route information traversed during accumulation as a test case data set based on the user searching behavior.
Specifically, traversing the whole sequenced route information, and counting the sum of the weights of the traversed items. If the weight corresponding to the traversed route information is greater than or equal to R, stopping traversing, namely,
Figure 499401DEST_PATH_IMAGE006
get it
Figure 376090DEST_PATH_IMAGE008
Wherein k is the k-th traversed route information; and selecting the information from the first traversed item to the kth air route, and sequentially using the information as a test case data set based on the user search behavior.
In this embodiment, by using a first preset weighted random sampling method, each route information is weighted and screened on the basis of the third-level hierarchical sampling data, so as to obtain a test case data set with a more reasonable coverage.
Further, in one embodiment, cold air route data is obtained as an important supplement to the data source based on user search behavior.
Specifically, the method comprises the following steps:
s01: and acquiring all-route data based on the flight schedule information.
S02: and obtaining cold air route data after filtering the air route information in the data source from the all-air route data.
The flight schedule information is all route data acquired from a preset database. Specifically, flight-based planning information is used as full-route data, route information in a data source is removed from the full-route data, and a cold route data set is obtained
S03: the cold air route data are sampled in the same three-level hierarchical screening mode as the steps S2 to S4, namely, the data are firstly layered according to the date and then layered according to the navigation department, and then the navigation department data are divided into a unique air route and a special air route. The cold route data comprises a departure place, a destination, a departure date, a navigation code and the like.
S04: and performing sample extraction on the third-level hierarchical sampling data screened out by the cold route data by using a second preset weighted random sampling method. Different from the first preset weighted random sampling method, the data of the cold route cannot be used as the weight because the data has no user search times, so that the number of flights corresponding to the route is selected as the weight, that is, the more the number of flights corresponding to one route is, the more important the route is, and the larger the weight is.
S05: in the manner described in steps S42 to S44, the cold route data is sampled to obtain a test case data set based on the cold route.
S06: and combining the test case data set based on the user search behavior and the test case data set based on the cold air route, and performing deduplication operation, namely, eliminating duplicate data in the test case data set based on the user search behavior and the test case data set based on the cold air route to obtain a target test case data set.
In this embodiment, the target test case dataset is derived from a data source based on a user search behavior and a test case dataset based on a cold air route, so that the data of the cold air route is covered, and the coverage of the test case is further improved to meet the test requirement.
By the sample generation method provided by the embodiment of the invention, a test case data set with high coverage rate and representativeness can be obtained; by constructing the sample data of the air ticket test case, the test requirement on the stability of the air ticket service is met by using lower cost, and the benign development of the service is facilitated.
On the basis, when the subsequent test system performs abnormity judgment, only the abnormity judgment is performed on the search result through a program, and when no result is returned to the airline, the tester performs manual reconfirmation, so that whether the whole program is abnormal is judged, and related personnel are notified to process the abnormal program.
