The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a test case generation method according to an embodiment of the present invention. The embodiment can be applied to the condition of testing the service software. Specifically, the test case generation method may be executed by a test case generation device, and the test case generation device may be implemented in a software and/or hardware manner and integrated in the test equipment. Further, the test equipment includes, but is not limited to: the test case testing system comprises electronic equipment capable of storing and running test cases, such as a desktop computer, a notebook computer, a smart phone, a server, an upper computer and the like.
As shown in fig. 1, the method specifically includes the following steps:
s110, determining the service state of the target service according to the service demand information and the service logic in the database.
Specifically, the service requirement information may be obtained from a product specification, a technical description document, a service introduction document, and the like, and includes functions, processes, service states, and the like that the target service needs to be implemented in actual application, and the service state that the target service should have may be extracted according to the service requirement information. The service logic in the database comprises functions, processes, service states and the like realized by software or codes designed and developed aiming at the target service, and the service state actually realized by the software developed aiming at the target service can be extracted according to the service logic.
Illustratively, taking a software test scenario of a service for applying for borrowing from a bank by a user as an example, the service requirement information means that the developed software is applied to realize the following processes: a user initiates a loan application to a bank, the bank checks the loan application and releases the loan, the user repays from the bank and the like, and related business states comprise an initial state (or an application state), a checking state, a releasing state, a repaying state and the like; the service logic refers to a state in which the developed software is implemented in the service logic in order to make the developed software meet the service requirement, such as an initial state (or an application state), an audit state, a release state, a payment completion state, a pre-payment state, and an overdue payment state. In general, the service state corresponding to the service logic covers all service states involved in the service requirement information.
According to the embodiment, all the service states to be tested of the target service are determined according to the service demand information and the service logic, the influence on the normal realization of the service due to the inconsistency of the service demand and the service logic can be avoided, and the comprehensiveness and the reliability of the test are ensured by comprehensively analyzing the service states. In addition, if the service logic is inconsistent with the service state of the service requirement, that is, the service logic does not include one or more service states corresponding to the service requirement information, it indicates that the service logic is wrong or incomplete, and a developer needs to modify the service logic of the developed software; and if the test cases are consistent, performing the subsequent steps of generating the test cases.
And S120, marking a conversion relation among the service states, wherein the conversion relation comprises convertible and non-convertible.
Specifically, the conversion relationship between the service states can be visually and accurately displayed by using forms such as tables, graphs and the like, including whether any two service states are convertible, and for each convertible two service states, the functional flow of each convertible service state needs to be tested through the test case. Optionally, in some embodiments, the conversion relationship may also include whether the conversion is unidirectional or bidirectional, the direction of the conversion, whether a condition, probability, or weight is attached, and the like.
For example, the target traffic has four traffic states in total: traffic state 1, traffic state 2, traffic state 3, and traffic state 4, for example, the switching relationship of the four traffic states is that traffic state 1 can be switched to traffic state 2 and traffic state 3, traffic state 2 can be switched to traffic state 4, and traffic state 3 can be switched to traffic state 1. One implementation is to generate a table with 4 rows and 4 columns, and fill in the transition relationship between the service state i and the service state j in the ith (i is 1,2,3,4) row and jth (j is 1,2,3,4) column of the table, so as to indicate whether the service state i can transition to the service state j. Another way to implement this is to use the service state 1, the service state 2, the service state 3, and the service state 4 as four vertices of a square, and then draw the transition relationship between any two service states in a manner pointed by arrows.
And S130, generating a test case of the target service according to the conversion relation.
Specifically, the test case generated according to the conversion relationship between the service states includes test codes of each group of convertible service states, and is used for testing whether any one service state can be correctly converted to the next service state to complete the corresponding service function.
According to the test case generation method provided by the embodiment of the invention, the service state of the target service is fully covered and the conversion relation among all the service states is accurately combed by comprehensively considering the service requirement and the service logic, so that a full and reliable test case is generated on the basis, and the comprehensiveness and the test reliability of the test case are improved.
Example two
Fig. 2 is a flowchart of a test case generation method according to a second embodiment of the present invention, where this embodiment is optimized based on the above embodiment, and specifically describes a process of labeling a transformation relationship and generating a test case according to the transformation relationship. It should be noted that technical details that are not described in detail in the present embodiment may be referred to any of the above embodiments.
Specifically, as shown in fig. 2, the method specifically includes the following steps:
s210, determining the service state of the target service according to the service demand information and the service logic in the database.
Taking a software test scenario of a service for which a user applies for borrowing from a bank as an example, determining a service state of the service according to service demand information and service logic comprises:
initial state (raft): a user initiates a borrowing request;
cancellation state (rubbbish): the user cancels the borrowing request;
audit refund status (audioscreen): the bank refutes the borrowing request, and the borrowing request is not passed;
audit pass status (CONFIRM): the borrowing request passes the audit;
service OPEN state (OPEN): the borrowing service is started, an order is created, and a bank issues a borrowing;
deposit complete status (FULL): the loan is fully issued to the account of the user;
service off status (CLOSE): closing the borrowing service and completing the loan issuance;
repayment status (REPAYING): the user initiates advance payment;
advanced payment status (PREPAYMENT _ FINISH): the user completes payment in advance within a specified time limit;
payment due status (FINISH): the user completes payment on the day of reaching the specified time limit;
default repayment status (OVER _ DUE): the user does not complete all repayment within the specified time limit and is in a default state;
default payment completion status (OVER _ DUE _ FINISH): and after the specified time limit is exceeded, the user completes all payment.
Payment generation status (payment _ credit): the user does not complete all the repayment within the specified time limit, and other accounts replace the user to complete all the repayment.
S220, generating a two-dimensional service state analysis table, wherein the header of the service state analysis table comprises each service state.
In this embodiment, the conversion relationship of each service state is labeled in a form of a two-dimensional table.
Fig. 3 is a schematic diagram of a service status analysis table according to a second embodiment of the present invention. As shown in fig. 3, all the service states are listed in the horizontal header and the vertical header, respectively, starting from a2 cell, all the service states are listed, and there are N ═ 13 service states, and the transition relationship between the service state i and the service state j is filled in the ith (i ═ 1, 2.., N) column of the table, which is used to indicate whether the service state i can be transitioned to the service state j, so as to facilitate the analysis of the transition relationship and the transformation into a case tree, and provide a basis for generating a comprehensive test case.
And S230, according to the service logic, marking a conversion relation between any two service states in the service state analysis table.
Specifically, the transition trend of the service states is determined by combining the service logic, and the preposed state and the postpositional state of each service state are determined. For example, in the service state analysis table illustrated in fig. 3, the service state in the vertical header is used as the current service state, the service state in the horizontal header is used as the next service state, and for one current service state, a position corresponding to the reachable next service state is labeled "Y" to indicate that the conversion relationship between the two service states is convertible; and marking a position corresponding to the next service state which cannot be reached by the user with "-" to indicate that the conversion relation between the two service states is not convertible. On the basis, the conversion relation between any two service states can be clearly and intuitively displayed.
S240, generating a corresponding use case tree based on the conversion relation in the service state analysis table as a convertible service state.
Specifically, in the process of generating the case tree according to the conversion relationship in the service state analysis table, only the conversion relationship labeled "Y" may be concerned, and the conversion relationship labeled "-" does not need to be considered, so that the generation process of the case tree is simplified, unnecessary analysis and calculation are avoided, and the efficiency of generating the test case is improved.
Fig. 4 is a schematic diagram of a use case tree according to a second embodiment of the present invention. As shown in FIG. 4, the conversion relationship between the nodes connected in the use case tree is convertible, and the conversion direction is from the upper node to the lower node of the use case tree. The case tree shown in FIG. 4 has 7 branches, and each branch should have a corresponding test case.
Further, the service state of the target service includes: an initial state and at least one non-initial state; the initial state corresponds to a parent node of the use case tree; each non-initial state corresponds to a child node of the use case tree.
Specifically, the initial state refers to a state of triggering a target service, for example, a service state of a user initiating a loan application; the non-initial state refers to various service states after the target service is triggered, such as a cancel state, an audit pass state, an advance payment state and the like. The initial state corresponds to a parent node of the use case tree, e.g., the DRAFT in fig. 4; the non-initial state corresponds to a child node of the use case tree, such as RUBBISH, CONFIRM, PREPAYMENT _ FINISH, etc. in FIG. 4.
And S250, generating a corresponding test case for each branch of the case tree.
Specifically, a corresponding test case is generated for each branch of the case tree, so that the circulation trend of the whole service state is covered. Table 1 is a test case table generated from the case tree shown in fig. 4. As shown in table 1, 7 test cases are formed together corresponding to the branches of the case tree, for example, case3 is used to test whether order can be normally created, loan is issued, issuance is completed, advance payment is initiated by the user and payment is completed within a specified period if the audit is passed; the case7 is used to test whether the order can be normally created, the loan is issued, the issuance is completed if the audit is passed, and whether the payment can be substituted by another account if the user defaults the payment, etc.
TABLE 1 test example Table
Optionally, labeling a conversion relationship between service states, including: under the condition that a preset condition is met, marking a conversion relation among the service states; wherein the preset conditions include: the corresponding service states in the service demand information all belong to service states in the service logic.
In this embodiment, it is determined that the service state needs to satisfy a certain preset condition according to the service demand information and the service logic, and the corresponding service states in the service demand information all belong to service states in the service logic, that is, the service logic is guaranteed to be correct and complete; otherwise, the developer is required to correct the service logic in the database according to the service requirement information, and label the conversion relation under the condition of meeting the preset condition.
Optionally, the conversion relationship between the service states includes: transition conditions between the traffic states.
In this embodiment, a conversion condition is attached to a conversion relationship between service states. For example, the initial state can be converted to other possible business states only if the assets, wages, credit data, etc. of the user are all eligible for a debit. The conversion conditions can be marked in a service state analysis table or a case tree, and the generated test case is also generated aiming at the convertible branches meeting the preset conditions. If the current service state does not meet the conversion condition to the next service state, the current service state may be circularly in the current service state, or converted to the initial state again, or directly jumped to the final service completion state, etc. For example, the service state 1 is switched to the service state 2 when the condition a is satisfied, is switched to the service state 3 when the condition B is satisfied, and if neither the condition a nor the condition B is satisfied, the service state 1 is maintained until one of the conditions is satisfied and then is switched to the next service state.
Optionally, the converting relationship includes: transition weights between the traffic states.
Specifically, when one service state can be converted into a plurality of service states, the conversion into each service state corresponds to a certain conversion weight. For example, if the service state 1 can be randomly switched to the service state 2 and the service state 3, the weights for switching to the service state 2 and the service state 3 are 0.5 respectively; for another example, if the weight value for the transition to the service state 2 is 0.8, and the weight value for the transition to the service state 3 is 0.2, the probability of the transition to the service state 2 is greater.
The test case generation method provided by the second embodiment of the invention is optimized on the basis of the first embodiment, the preposed state and the postpositional state of each service state are determined by utilizing the service state analysis table and the case tree, and the conversion relation between any two service states is clearly and intuitively displayed, so that a comprehensive test case is generated, and the test case generation efficiency is improved; by attaching the conversion conditions and the conversion weight, the test case is generated more flexibly, has expandability and is suitable for various service scenes; and the service state is analyzed under the condition of meeting the preset condition, so that the correctness and perfection of service logic can be ensured, the quality of the test case is improved, and the reliability of the test is further improved.
