Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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.

The existing subway operation scene case testing method generally has the problems of low test task completion efficiency and long time consumption caused by the fact that cases are tested one by one in a test case library of a project and waste of manpower and material resources caused by the fact that the same test case is tested repeatedly in the same traffic scene. The following describes the test case layout method based on the intersection information of the line to be tested according to the present invention with reference to fig. 1 to 3. Fig. 1 is a schematic flow chart of a test case layout method based on traffic information of a line to be tested, as shown in fig. 1, the method includes:

and step 110, extracting actual scene elements and position attributes in the intersection information of the line to be detected.

Optionally, the line to be tested is an actual line to be tested, which includes test cases corresponding to all the position scenes, and is also a main body to be laid with the test cases, that is, the test cases are laid in each position scene of the line to be tested. The premise of arranging the layout is to acquire which position scenes the line to be tested contains and which test cases each position scene can be tested in, and the information acquisition needs to be obtained from a pre-constructed traffic scene database. And the query condition for acquiring the information of the line to be tested from the intersection scene database is an actual scene element in the intersection information of the line to be tested. Scene elements refer to different operational sections included in the intersection information of lines in the subway operational scene, for example: a straight double track section between two stations, a station section, a single track turnout section, a crossing turnout section, and the like. For a line to be tested comprising three stations, two straight double-track sections and a single-track switch, the scene elements in the line to be tested are: the system comprises a platform, a straight double-track section and a single-track switch, wherein scene elements in the line to be detected are the same as scene elements of another line to be detected comprising seven platforms, six straight double-track sections and four single-track switches, the intersection scenes of the two lines can be judged to be the same only by confirming the consistency of the scene elements in the two lines, and the number of the scene elements in the two lines can be different. And the position attribute in the line to be detected is used for matching the position attribute with the template position scene in the template cross road scene after a template cross road scene corresponding to the line to be detected in the cross road scene database is searched subsequently, and determining the actual position scene in the line to be detected.

And 120, inquiring an intersection scene database based on the actual scene elements, and determining a template position scene corresponding to an intersection scene to which the line to be tested belongs, wherein the intersection scene database comprises a pre-stored corresponding relation between a test case and the template position scene, a corresponding relation between the template position scene and the template intersection scene, and a corresponding relation between the template intersection scene and the scene elements.

Optionally, the traffic scene database is a database which is constructed in advance and stores a correspondence between the test case and the template position scene, a correspondence between the template position scene and the template traffic scene, and a correspondence between the template traffic scene and the scene element. And by taking the actual scene elements of the line to be detected as query conditions, finding out a template intersection scene of which the intersection scene database is consistent with the scene elements of the line to be detected, taking the template intersection scene as an intersection scene to which the line to be detected belongs, and extracting a template position scene contained in the template intersection scene from the scene database.

Step 130, determining an actual position scene contained in the line to be tested based on the position attribute of the line to be tested and a template position scene corresponding to the intersection scene to which the line to be tested belongs, wherein the number of the actual position scenes is not less than 2.

Optionally, since the intersection scene to which the line to be tested belongs is the template intersection scene obtained by querying the intersection scene database in step 120, and the intersection scene database further includes the corresponding relationship between each template position scene and the template intersection scene, and the corresponding relationship between the test case and each template position scene, since the actual position scene included in the line to be tested does not exceed the range of the template position scene corresponding to the corresponding template intersection scene queried in the intersection scene database, the actual position scene in the line to be tested can also be obtained by traversing all the template position scenes in the template intersection scene and sequentially performing matching with the position attribute in the line to be tested. For example, there are four template position scenes corresponding to the template intersection scene: crossing ZC demarcation point, interval, rail and website of turning back, and through crossing four stencil position scenes of ZC demarcation point, interval, rail and website of turning back in the stencil intersection scene carry out the matching with the position attribute in the circuit that awaits measuring in proper order, obtain the actual position scene in the circuit that awaits measuring and have three kinds: crossing ZC demarcation points, intervals and retrace tracks. The number of the actual position scenes is limited to be not less than 2, because when the number of the actual position scenes is only one, the mutually matched layout of the test cases among the position scenes is not needed, and in this case, the test of all the test cases in the only actual position scene is only needed to be completed when the test task of the line to be tested is executed.

And 140, processing the test cases contained in the actual position scenes based on a preset duplication elimination rule, and determining the test cases to be tested in the actual position scenes.

Optionally, for the same intersection scene, the same test cases on different position scenes can be merged, that is, only one test is selected in one position scene, and repeated tests are not needed, so that resource waste of manpower and material resources can be avoided, the efficiency of completing the test task is improved, and time consumption is reduced. The preset deduplication rule may be various rules, for example, the simplest test case of the same kind that repeatedly appears in different location scenes, one of the different location scenes is randomly selected as the location scene when the test that is laid out is performed, the test cases may be centralized in deduplication processing that includes the location scenes thereof, the deduplication processing may be performed with the minimum number of actual location scenes required by the test cases as a target when a union set of the test cases included in each actual location scene is tested, and the like, the preset deduplication rule is not specifically limited, different de-duplication processes can be carried out according to different test scene requirements to obtain different test case layouts, and compared with the prior art, the de-duplication test method has higher test task completion efficiency and less test task time consumption, the waste of manpower and material resources caused by repeated testing of the same test case in the same traffic scene can be avoided; different deduplication rules only have advantages for different application scenarios, such as small calculation amount, centralized utilization of manpower in the same location scenario, or reduction of the number of location scenarios participating in the test task to avoid mobilization of test personnel between different location scenarios.

The test case layout method based on the to-be-tested line traffic information provided by the invention extracts the actual scene elements and the position attributes in the to-be-tested line traffic information; then inquiring a traffic scene database based on the actual scene elements, and determining a template position scene corresponding to the traffic scene to which the line to be tested belongs, wherein the traffic scene database comprises a pre-stored corresponding relation between a test case and the template position scene, a corresponding relation between the template position scene and the template traffic scene, and a corresponding relation between the template traffic scene and the scene elements; determining an actual position scene contained in the line to be tested based on the position attribute of the line to be tested and a template position scene corresponding to an intersection scene to which the line to be tested belongs, wherein the number of the actual position scenes is not less than 2; and finally, processing the test cases contained in the actual position scenes based on a preset duplication elimination rule, and determining the test cases to be tested in the actual position scenes. The method comprises the steps of determining a cross road scene of a line to be tested in a cross road scene database based on actual scene elements, matching a template position scene corresponding to the cross road scene of the line to be tested with position attributes of the line to be tested to determine an actual position scene contained in the line to be tested, and processing a test case contained in each actual position scene according to a preset deduplication rule to obtain the layout of a proper test case in each actual position scene, so that the situation that the same test case is repeatedly laid in different position scenes in the same cross road scene is avoided. Therefore, the method provided by the invention improves the efficiency of completing the test task, reduces the time consumption of the task, and can avoid the waste of manpower and material resources caused by repeated testing of the same test case in the same traffic scene.

On the basis of the above embodiment, the processing, based on the preset deduplication rule, the test cases included in each actual location scene, and determining the test cases that need to be tested in each actual location scene specifically include:

determining a union set of test cases contained in each actual position scene;

Optionally, the duplication removal is performed on the test cases included in each actual position scene, namely, a union set of the test cases included in each actual position scene is determined, the union set is determined, that is, all the test cases which need to be tested when a test task is performed are checked, and the checked test cases are subsequently distributed to the corresponding position scene to ensure that each test case is tested only once, that is, the repeated testing of the same test case is avoided. The subsequent layout method provided by this embodiment randomly selects one of the actual position scenes corresponding to any test case element and collects the selected actual position scene, and determines the position scene where the test case element is located when testing. For example, the line to be tested has four actual position scenes, namely an actual position scene 1, an actual position scene 2, an actual position scene 3 and an actual position scene 4, and the traffic scene database can know that the actual position scene 1 corresponds to the template position scene 1 of the traffic scene to which the actual position scene belongs and the template traffic scene in the traffic scene database, and the traffic scene database also stores the corresponding relationship between the test cases and the template position scenes, so that the test cases included in the template position scene 1 can be inquired, that is, the test cases of the actual position scene 1 can be obtained, and the test cases included in the actual position scene 2, the actual position scene 3 and the actual position scene 4 can also be obtained respectively by the method. Assuming that the obtained actual location scene 1 includes test case 001, test case 003, test case 004, and test case 007, the actual location scene 2 includes test case 003, test case 004, test case 007, and test case 008, the actual location scene 3 includes test case 003, test case 007, test case 009, and test case 010, and the actual location scene 4 includes test case 001, test case 002, test case 005, and test case 006, then for test case 003, it can be determined and collected as { test case 001, test case 002, test case 003, test case 004, test case 005, test case 006, test case 007, test case 008, test case 009, test case 010}, for example, for test case 003 therein, one position scene laid during testing can be randomly selected from the actual position scene 1, the actual position scene 2 and the actual position scene 3 as a test case. The layout of the position scenes when the test cases appearing in different position scenes are tested by using the random determination mode can reduce the calculated amount of the preset deduplication rule processing and reduce the processing complexity, and is suitable for the condition that the execution main body, namely the corresponding device, of the test case layout method based on the to-be-tested line traffic information, which is provided by the invention, is low in hardware performance.

On the basis of the above embodiment, the preset deduplication rule is: and when the union set of the test cases contained in each actual position scene is tested, centralizing the test cases in the position scene containing the test cases.

Optionally, the duplication removal is performed on the test cases included in each actual position scene, namely, a union set of the test cases included in each actual position scene is determined, the union set is determined, that is, all the test cases which need to be tested when a test task is performed are checked, and the checked test cases are subsequently distributed to the corresponding position scene to ensure that each test case is tested only once, that is, the repeated testing of the same test case is avoided. The subsequent layout method provided by this embodiment sequentially and preferentially selects the location scene containing the most test cases to provide and concentrates the location scenes when the test cases need to be tested. For example: the line to be tested has six actual position scenes, namely an actual position scene 1, an actual position scene 2, an actual position scene 3, an actual position scene 4, an actual position scene 5 and an actual position scene 6, and the traffic scene database can know that the actual position scene 1 corresponds to the template position scene 1 of the traffic scene to which the actual position scene corresponds to the template traffic scene in the traffic scene database, because the corresponding relation between the test case and the template position scene is also stored in the cross road scene database, the test case contained in the template position scene 1 can be inquired, that is, the test cases of the actual position scene 1 can be obtained, and the test cases included in the actual position scene 2, the actual position scene 3, the actual position scene 4, the actual position scene 5, and the actual position scene 6 can be obtained by the above method. Assuming that the obtained actual position scene 1 includes test case 001, test case 002, test case 003, test case 004, test case 005, test case 006 and test case 007, the actual position scene 2 includes test case 008, the actual position scene 3 includes test case 007, the actual position scene 4 includes test case 010, the actual position scene 5 includes test case 001, test case 002, test case 005, test case 007 and test case 009, the actual position scene 6 includes test case 003, test case 004, test case 006, test case 008 and test case 010, then the position scenes including the most test cases can be selected in turn to provide and concentrate the position fields when the test cases need to be tested, wherein the position scenes including the most test cases are selected in turn to provide and concentrate the position fields when the test cases need to be tested Firstly, determining that the actual position scene 1 is the position scene containing the most test cases, then testing in the actual position scene 1 when the test cases 001, 002, 003, 004, 005, 006 and 007 are laid for testing tasks, for the remaining { test case 008, test case 009, test case 010}, since the actual position scene 6 contains more test cases 008 and 010 than other actual position scenes contain the rest test cases, therefore, when the test cases 008 and 010 are laid out to perform the test task, the test is performed in the actual position scene 6, for the last remaining test case 009, the actual position scene 5 that only contains the test case 009 is selected as the position scene where the test case 009 was subjected to the test task. Therefore, the duplication elimination processing mode of intensively arranging a large number of test cases in the same actual position scene is used, so that the human resources in the same position scene can be fully utilized, the repeated calling of the test cases for multiple times in the same actual position scene can also reduce the time for repeated setting of the same setting among the test cases, the consumed time is reduced, and the duplication elimination processing mode is suitable for the condition that the test task of the line to be tested is executed and has strict time limitation.

determining a union set of test cases contained in each actual position scene;

Optionally, in this embodiment, the position scenes that include the most test cases and are provided in sequence and preferentially selected and the test cases are concentrated when the test cases need to be tested are described by using a specific mathematical formula, so that how to perform the position scenes that include the most test cases and are provided in sequence and preferentially selected and the test cases need to be tested can be more clearly indicated. Firstly, finding out an actual position scene containing the most test case elements in the union set as a first position scene, then determining all test cases contained in the first position scene as the position scene where the test is carried out, then removing all test cases contained in the first position scene from the union set to obtain a first remainder set, wherein in order to ensure that the description for determining the i-th remainder set and the i + 1-th remainder set of all test cases contained in the i + 1-th position scene are the i + 1-th remainder set is common to the determination of the first remainder set, the condition that i is 0 is separately defined, namely the zero-th remainder set is the union set, and then determining the actual position scene containing the most test case elements in the i + 1-th remainder set as the i + 2-th position scene; continuing to remove the test cases which can be laid in the currently selected position scene from the current remainder set to obtain a remainder set selected in the next round of position scenes containing the most test cases, namely determining that the intersection of all the test cases contained in the (i + 2) th position scene and all the test cases contained in the (i +1) th position scene is the (i +1) th sub-intersection, and determining that the remainder set of the intersection of all the test cases contained in the (i + 2) th position scene and the (i +1) th sub-remainder set; and determining the (i + 2) th position scene as a position scene where the (i +1) th sub-remainder set comprises all test cases for testing. The end flag of this loop is to stop the iteration if the elements of the ith residual set and the ith sub-residual set are equal, i.e. N is the value of i when the number of elements in the ith residual set and the ith sub-residual set is 0.

On the basis of the above embodiment, when the preset deduplication rule tests the union set of the test cases included in each actual position scene, the minimum number of the actual position scenes required by the test cases is taken as a target.

Optionally, the duplication removal is performed on the test cases included in each actual position scene, namely, a union set of the test cases included in each actual position scene is determined, the union set is determined, that is, all the test cases which need to be tested when a test task is performed are checked, and the checked test cases are subsequently distributed to the corresponding position scene to ensure that each test case is tested only once, that is, the repeated testing of the same test case is avoided. The subsequent layout method provided by this embodiment aims to minimize the number of actual position scenes required by the test case during testing. For example: the actual position scene 1 includes a test case 001, a test case 002, a test case 003, a test case 004, a test case 005, a test case 006, and a test case 007, the actual position scene 2 includes the test case 008, the actual position scene 3 includes the test case 007, the actual position scene 4 includes the test case 010, the actual position scene 5 includes the test case 001, the test case 002, the test case 005, the test case 007, and the test case 009, the actual position scene 6 includes the test case 003, the test case 004, the test case 006, the test case 008, and the test case 010, and then { the test case 001, the test case 002, the test case 003, the test case 004, the test case 005, the test case 006, the test case 007, the test case 008, the test case 009, and the test case 010} can be determined and collected, and selected to be distributed in the actual position scene 5 for the test case 001, the test case 002, the test, The test cases 002, 005, 007, 009 perform tests on the test tasks, and the test cases 003, 004, 006, 008, 010 perform tests on the test tasks in the actual position scene 6. Therefore, the number of actual position scenes participating in the test task is reduced, and the movement of the tester among different position scenes can be avoided.

On the basis of the above embodiment, the construction of the traffic scene database specifically includes:

Optionally, to construct the traffic scene database, data in the traffic scene database needs to be integrated on the basis of an existing test case library, and a corresponding relationship between a test case and a position scene is extracted, and a corresponding relationship between the position scene and a traffic scene and a corresponding relationship between the traffic scene and a scene element are extracted, so that a large amount of disordered data without obvious association can be sorted into different corresponding tables through different corresponding relationships between the data so as to be extracted regularly during subsequent data extraction. Furthermore, the corresponding relation between the test case and the position scene is described by using the corresponding relation matrix, and the corresponding relation between the position scene and the traffic scene is also described by using the corresponding relation matrix.

Fig. 2 is a structural diagram of a corresponding relationship between data stored in the traffic scene database provided by the present invention, as shown in fig. 2: firstly, a test case library is obtained, test cases in the test case library are classified, and each test case corresponds to one or more test case scenes. Each test case scene corresponds to an actual operation position in a line, and each type of test case scene contains all test cases to be executed at the operation position in the line, so the test case scene is also called as a position scene because the test case scene corresponds to the actual operation position in the line. The operation scenes are composed of different test case scenes, and at least one test operation scene is determined by determining train operation cross roads according to the actual operation line of the train, so the test operation scene is also called as a cross road scene. And (3) with train operation cross roads as a carrier, embedding the test cases in the test case library into a test operation scene to generate a test operation scene library, namely a cross road scene database.

The test scenes are generated by combining test cases to analyze the route scenes which the train may pass under the CBTC system level and the input and output of the basic functions of the train under the route scenes on the basis of the existing subway line conditions. And analyzing and classifying all cases in the test case library, and making the test case library into a scene. Fig. 3 is a schematic diagram of test case library scenario provided by the present invention, as shown in fig. 3:

the test case library scene concrete implementation steps are as follows:

1. generating a test case scene class (namely the corresponding relation between the position scene and the test case):

the production of the test case library is to analyze the specific conditions and scenes of the existing line, classify the test cases by combining the characteristics of the test cases, divide the test cases into a plurality of classes, wherein each class corresponds to a specific position scene in the line, and the class contains all cases which can be executed in the position scene in the line. Thus, all test cases in the complete test case library are divided into a plurality of case scenarios. Table 1 is a relational matrix table of the correspondence between the test cases and the location scenes, and as shown in table 1, it represents the generated corresponding matrix between the test cases and the case scenes (i.e., the location scenes), and the test case scene class covers the sum of all the test cases in the test case library.

Table 1 relationship matrix of correspondence between test cases and position scenes

And finishing the classification of the test cases. The above table shows that all the test cases are classified, and the sum of all the cases in the test case library is covered in the case scene class.

2. Generating a test operation scene library (namely a traffic scene database):

the train operation cross road scene is used as a carrier, the test cases are used as nodes, the operation cross road scene is abstracted into a description form of an image, a common search algorithm is used for searching according to the characteristics of the cases to be tested in the position scene, and a complete test operation scene library, namely a corresponding relation matrix of the position scene (Case) and the cross road scene, is generated through multiple iterations.

Table 2 is a relational matrix table of the corresponding relationship between the position scene and the traffic scene, as shown in table 1, which is a relational matrix of the relationship between the test case and the test operation scene generated according to the above method:

table 2 relationship matrix of the corresponding relationship between the position scene and the traffic scene

In table 2, the label "1" indicates that the test case included in the location scenario is executed when the corresponding traffic scenario performs test operation, and the label "0" indicates that the test case included in the location scenario is not executed when the corresponding traffic scenario performs test operation, which can be seen from table 2.

To describe the implementation manner of the corresponding relationship between the location scene and the test case more intuitively, the following examples are given:

the following test cases are selected from the existing test case library as a sample case library:

case 001: handling one route to run at the CBTC-CM level;

case 002: handling one route down operation (ZC demarcation point) at the CBTC-CM level;

case 003: CBTC-CM foldback;

case 004: ITC-CM is converted into CBTC-CM;

case 005: CBTC train stop guarantee;

case 006: and detecting whether the CBTC train can normally move across a ZC boundary point or not in the process of entering a ZC (N +1) jurisdiction from a ZC (N) jurisdiction.

The test cases in the sample case library can be divided into three types of test case scenes, namely

Case C1: crossing ZC demarcation points;

case C2: an interval;

case C3: and turning back the rail.

Table 3 is a relational matrix table of the corresponding relationship between the test case and the case scenario class (i.e. location scenario), and table 3 is as follows:

TABLE 3 relationship matrix of the corresponding relationship between test cases and case scene classes
