Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
In addition, the case attribute module mentioned in the embodiment of the present invention refers to a set of attribute information corresponding to the same test case, and the test case attribute information may be various descriptive information representing the test case, and may include, for example, a test case number, a test step, a delay time, and a call setting value.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1, an automated testing method for a vehicle control unit according to an embodiment of the present invention includes:
and S11, acquiring an automatic test request.
Regarding the execution subject of the method of the embodiment of the present invention, on one hand, it may be realized by a device or an instrument dedicated to executing the automated test of the vehicle control unit; on the other hand, it may also be an automated test unit or an automated test module configured on a general-purpose terminal or device for implementing the automated test method of the embodiment of the present invention, for example, a corresponding code for testing may be configured on the automated test unit or the automated test module. By way of example, it may be implemented based on code, units, or modules applied to hardware in a loop test system (HIL).
The automatic test request acquisition mode can be realized based on the operation of a user on the automatic test equipment; it should be noted that, in the embodiment of the present invention, the person who requests to execute the automated test is not required to be a professional person who needs to understand the programming language of the test case, and the person may be a person who can realize the automated test operation without completely knowing the professional programming language of the test case. Wherein the test request is specific to one or more specific test cases to request the automatic test to be executed on the test cases.
S12, inquiring the attribute case association table based on the automatic test request to determine a target case attribute module corresponding to the automatic test request, wherein the attribute case association table comprises a plurality of case attribute modules, and each case attribute module points to different test cases.
The attribute case association table in the embodiment only needs to point and associate the attribute module and the test case, so that the test case is called, and therefore the attribute case association table can be suitable for various types of test cases.
And S13, calling the pointed target test case based on the determined target case attribute module, and executing the automated test.
In this embodiment, through the pre-configured attribute case association table, the directional association is performed between the case attribute module and the test case, so that the corresponding case attribute module can be found by responding to the automatic test request for the table look-up type request, and further, the call of the targeted test case is realized, and the automatic test process of the test case is effectively realized. Therefore, the current complicated manual operation testing process is upgraded into automatic testing (such as automatic testing based on a software program), so that the manual intervention in the testing process is avoided, the accuracy and subjectivity of the testing process are improved, the testing result is more feasible, and the requirement is finally realized in a full coverage manner.
It should be noted that, as described above, the use case attribute module refers to a set of attribute information corresponding to the same test case, and all the expressed contents are contents that are easily understood by the user; therefore, the automatic test request related to the table lookup can be made by the user based on the comprehension of the descriptive information, so that the user executing the automatic test task does not even need to understand the meaning of the test case, the user can call the specific test case only by operating the attribute case association table, even does not need a professional test engineer to access the operation, the application range of the automatic test is expanded, and the test cost is reduced.
In some embodiments, test conditions (for example, an and relationship or an or relationship) combination can be performed on the pointed target test case, so that a plurality of groups of test cases with different test conditions can be derived, and test case recombination is automatically realized, so that the test case requiring the test condition combination is automatically tested, test requirements of some personalized test scenes are met, and test experience of a user is improved.
Preferably, the user may also issue the automatic test request by operating on the same table, for example, setting test request information in the table, and then when performing the automatic test, obtaining the automatic test request by reading the table. An example of a specific execution flow of S11 as shown in fig. 2 includes:
and S111, reading test request information set by a user from the test case association table, wherein the test request information comprises selection information aiming at the case attribute module.
And S112, generating the corresponding automatic test request based on the test request information.
More specifically, it may also be that the test request information is set at a predefined location of the test case association table, so that the test request information at the predefined location can be read when the automated test operation starts, thereby generating the automated test request.
In some preferred embodiments, the selection information further includes call times information, thereby enabling determination of the number of times of calling to execute the test case according to the call times information, and enabling execution of the automated test corresponding to the call times information on the determined target test case when the automated test is executed. When the calling frequency information is more than 1 time, the cyclic automatic test can be executed on the determined target test case by inputting the request once without repeating complicated multiple inputs, so that the test experience of the user is improved.
In some embodiments, only part of steps in the test case can be tested, and the whole test case does not need to be called and executed, so that the test efficiency is improved. Specifically, the test start value, the test end value, and the test step value may be set in the selection information, so that when the automated test is executed, the selected case attribute module may be resolved and split according to the test start value and the test end value, then a continuous test sequence may be generated according to the split case attribute module and the test step value, and the continuous automated test may be executed based on the continuous test sequence. As an example, when the input test number is set as a, the start value is 50, the end value is 100, and the step size is 10, a 50-100 continuous test sequence corresponding to 5 steps can be automatically obtained, so as to complete the continuous automatic test of the selected step interval under the use case, and multiple inputs are not required, thereby avoiding the deviation caused by multiple input settings of the user.
Regarding the construction method of the attribute use case association table in the embodiment of the present invention, on one hand, the relationship between the use case attribute module and the corresponding test use case may be artificially constructed, so as to implement the construction of the use case attribute module; on the other hand, it may also be implemented by an automatic creation mode, such as the flow of automatically creating the attribute use case association table shown in fig. 3, specifically including:
and S31, acquiring a plurality of test cases.
The obtained multiple test cases may be all test cases that may be involved in future tests.
S32, respectively reading the test case attribute information of a plurality of test cases, and aggregating the read test case attribute information to generate a case attribute module pointing to the read test case.
And S33, creating an attribute use case association table according to the generated use case attribute module.
In some embodiments, it may be necessary to ensure that the test case attribute information is from the same data format to ensure the reliability of the aggregated use case attribute modules. Therefore, when the test case is input, the test case should meet a uniform text format, for example, all the test cases may be in an excel text format; preferably, when the case attribute information is read, the plurality of test cases may be converted into a corresponding standard case input text format (for example, an excel text format), and the test case attribute information is read from the plurality of test cases in the standard case input text format.
In some embodiments, the test case attribute information may be read based on a python generator to automatically identify a data format of the test case attribute information, such as a null value, a non-null value, a special character string, and the like, thereby implementing fast reading of data and occupying a small memory. In addition, the work flow of the python generator to read information is not only applicable to the table creation phase, but also applicable to the phase of executing the test in response to the request, and the effect of fast reading of data can be achieved.
As shown in fig. 4, in an example of the attribute use case association table according to an embodiment of the present invention, data in each column is stored in a dictionary (dictionary) format, for example, the data may be stored with a column position as key and a value in each column as value.
In some preferred embodiments, it is desirable to obtain test results directly during automated testing, rather than just test data. As shown in fig. 5, an automated testing method for a vehicle control unit according to an embodiment of the present invention includes:
and S51, acquiring an automatic test request.
S52, inquiring the attribute case association table based on the automatic test request to determine a target case attribute module corresponding to the automatic test request, wherein the attribute case association table comprises a plurality of case attribute modules, and each case attribute module points to different test cases.
And S53, calling the pointed target test case based on the determined target case attribute module, and executing the automated test.
For details and effects of the embodiments of S51-S53, reference may be made to the above description of the related embodiments, and therefore, the details are not repeated herein. Further, in order to intuitively obtain the test result, it may be realized by performing the following operations.
And S54, when the automatic test data are generated, comparing the automatic test data with expected test data corresponding to the target case attribute module to obtain an automatic test result, wherein the attribute case association table comprises the expected test data corresponding to each case attribute module.
And S55, storing the automatic test result to the attribute case association table for real-time reference by the user.
In this embodiment, the automatic test result may be directly stored in the attribute case association table, so that the user can intuitively refer to the test result of the test case. Therefore, the embodiment of the invention can realize that the result can be generated in real time and can be consulted by the user in real time after the test result of one test case is finished, and the user does not need to consult the test case after all the test cases are finished, so that the user can conveniently know the test condition in time, the user is allowed to quickly take measures, and the automatic test experience of the whole vehicle controller is improved.
In the embodiment, the standard format test case input text is provided, so that the requirements of different types of test cases can be met. The test case file can be automatically read, the corresponding parameter names and values in the test text are stored in a data dictionary format, the test process circularly calls a universal test script unit, an automatic test operator who completes the case can complete the automatic test only by maintaining the test case file without knowing a programming language and compiling the test script, and the high automation of the system test can be completed. In addition, many effects can be achieved by implementing the embodiment of the present invention, for example: firstly, the testing period can be shortened to the greatest extent, so that the optimization of time and labor cost is realized, the product development cost is saved, and the product development period is shortened. Secondly, the test result can be observed and judged in real time, signals with short duration in the process are captured and read, and post-processing analysis of data is avoided; and thirdly, an operator does not need to know the programming development language, only needs to know the test requirement and input the test document, the test process can be completed, and the combined operation of different work types can be realized.
As shown in fig. 6, the architecture of the automatic test system of the vehicle control unit according to an embodiment of the present invention may be a test environment based on the original HIL and INCA calibration software, a test software platform is added, and a python programming language calculation method is adopted to program the test process, so as to achieve the VCU test automation. Specifically, it may include three test units: the test data reading unit, the test unit and the data result storage unit are simple to maintain, and can configure the test repetition times of the use case in the test use case configuration file to realize the repeatability test; the configuration file can also carry out selective configuration on the test case, and can carry out test configuration forbidding if the test is not needed, so that the point inspection test is realized. The test unit adopts an interface function, duplicate removal operation is not needed, and the worry that a certain variable is repeatedly input in a test case is avoided.
As shown in fig. 7, an example of the working principle of the automatic test system of the vehicle control unit according to the embodiment of the present invention may be that a test identifier is added to a test document, so that test cases can be screened and executed. The method mainly comprises the definition of an input file of Excel and the development of automatic testing software.
The following examples of the method of the embodiment of the present invention applied to a machine-readable storage medium of an integrated automation test software program code specifically include the following aspects:

Illustratively, the specific standard template may be a table as shown with reference to fig. 4. Firstly, before testing, the test case document needs to be maintained, including: number, test description, number of tests, whether to test, test steps, delay time, set values, and expected values. The test step and the expected value are the parts mainly needing maintenance, and init and step (set value and expected value) need to be maintained in the test step. Engineers need to input the test documents according to requirements, and the test conditions and the test results are ensured to be correct.
On the other hand, the development of the automated testing software may be to read a maintenance document (as input), automatically read an actual measurement result, automatically analyze a testing procedure, automatically evaluate a testing result, and automatically generate a testing report.
The automatic test method of the vehicle control unit comprises the following steps:
1) reading maintenance documents
The test software can automatically identify batch test case files, for example, the test script file is x, xls, different testers can put respective test cases into a designated folder, and the software can automatically complete execution of all test cases, so that the testers are prevented from independently testing. The item is characterized in that the input data of the maintenance document is read by software, the software can read the number, the test description, the test step, the time, the set Value and the expected Value, each column is stored in a dictionary (dictionary) format, the column position is used as a key, the Value of each column is used as Value, the data is read in a python generator (yield) mode, and the software can automatically identify the data format (null Value, non-null Value and special format character string). The software can automatically recognize the keywords in the dictionary, thereby executing different flow operations.
In the test flow shown in fig. 8, all test cases share one universal test script unit, which avoids that each test case needs to write its own test script, and is simpler to maintain. Meanwhile, the software provides an open function interface, and an operator can compile own private functions, so that the embedding of different test requirements is facilitated, and the upgrading of the software is also facilitated. In the testing process, the software analyzes the test variable name and the test variable value from the data dictionary to carry out data input and result comparison. And the testing step is used for testing and judging results.
