The file to be flashed is a corresponding ECU flashing file.
In step S12, before the test step is executed, the expected result parameters corresponding to each test step are called in the configuration parameters, it should be noted that, for different test steps, the expected result parameters corresponding to the different test steps may be the same or different, but before the test step is executed each time, the expected result parameters corresponding to the current test step need to be called in the configuration parameters. The test case of the file to be flashed is executed through a plurality of test steps under the current test project, namely the test case of the file to be flashed is executed according to all test steps under the current test project, the test case comprises the test steps formed by combining the flashing test points on the basis of the project flashing flow, and the functional programs corresponding to all test steps under the current test project are packaged in advance. The files corresponding to the functional programs are modularized and independent, so that each testing step in the flashing process has no dependency relationship, and the independent association of logic and projects is realized.

The reverse test point comprises a power supply short-circuit disconnection step, a Controller Area Network (CAN) short-circuit disconnection step, a skipping brushing step and the like, the step to be skipped is removed on the basis of the previous complete process if the brushing step is skipped, and the pressure test is carried out for thousands of times on the basis of the forward test point or the reverse test point.
And step S13, detecting the current testing step according to the expected result parameters to obtain a detection result. The detection process may be comparing the actual parameter with the expected result parameter, wherein the corresponding detection result is successful when the comparison is successful, and the corresponding detection result is failed when the comparison is failed.
And under the condition that the detection result is successful, the function of the test step can be detected, and the detection process is to call each function instruction to obtain the test result. And calling each functional instruction as a diagnosis instruction, determining that the test result is successful when the diagnosis results are successful, and determining that the test result is failed if one of the diagnosis results is failed.
After the test of the current test step is completed, under the condition that the test result is successful, the test of the next test step is carried out, namely the next test step is taken as the current test step, and the step S12 is returned until the test of all the test steps is completed. It should be noted that, in the case that the test result fails, the test of the current test step is directly ended, and the test process is not executed in the subsequent test step, so that the test result is determined to fail. And under the condition that the test result fails, directly ending the test of the current test step, and determining that the test result fails without executing the test process in the subsequent test step.
The embodiment of the invention provides a flash test method, which comprises the following steps: acquiring configuration parameters of a current test project and a file to be flashed; calling an expected result parameter corresponding to the current testing step from the configuration parameters, wherein a test case of a file to be flashed is executed through a plurality of testing steps under the current testing project, the test case is obtained by combining functional programs corresponding to the plurality of testing steps according to the configuration parameters, and the functional programs corresponding to the plurality of testing steps are packaged in advance; testing the current testing step according to the expected result parameters to obtain a testing result, and calling a diagnosis function instruction to test the function corresponding to the current testing step under the condition that the testing result is successful to obtain the testing result; and under the condition that the test result is successful, taking the next test step as the current test step, and returning to the step of calling the expected result parameter corresponding to the current test step in the configuration parameters until the flash test of the test step in the test case is completed. According to the method, the configuration parameters and the flash process are separated, the test process is independent into each test step according to each function program, and each function program is combined according to the configuration parameters to obtain the test case, so that the test steps get rid of the dependency relationship with the current test project, and the corresponding flash process of the existing test project is prevented from being redeveloped. The method and the device have the advantages that the testers do not need to be familiar with the flash flow, the test points and the flash process realization principle of each test item, the technical level requirements on the testers are reduced, and the test steps can be arranged only according to the configuration parameters to realize the flash test process. In addition, before testing each test step, the test of expected result parameters is firstly carried out, the test processing is carried out only under the condition that the test result is successful, and the test of the next test step is carried out after the test result of the current test step is successful, so that the test time is saved, the universality of the flash test and the efficiency of the whole flash process are improved, and the accuracy of the final test result is improved.
On the basis of the above embodiment, the step S13 of checking the current testing step according to the expected result parameters to obtain a checking result includes:
obtaining a return result parameter of the current testing step, wherein the return result parameter is a result parameter fed back by calling a checking instruction sent by the current testing step;
comparing an expected result parameter corresponding to the current testing step with a returned result parameter;
when the expected result parameter is the same as the returned result parameter, determining that the test result is successful;
and when the expected result parameter is different from the returned result parameter, determining that the inspection result is failure.
Specifically, a return result parameter of the current testing step is obtained, where the return result parameter is an inspection instruction sent by calling the current testing step, and then a reply instruction, that is, a result parameter, is sent correspondingly according to the received detection instruction. It is understood that the returned result parameter is an actual parameter of the current testing step before the execution, and the expected result parameter corresponding to the current testing step is compared with the returned result parameter. The comparison process is to compare one digit of each character string with one digit, and when the digits are different, the two parameters are different. The comparison process can also be carried out in a regular matching mode to accelerate the comparison time, and other comparison modes can also be adopted, so that limitation is not required, and the comparison process can be set according to actual conditions.
And when the comparison results of the two parameters are the same, determining that the detection result is successful, and when the comparison results are different, determining that the detection result is failed.
In the test process of the expected result provided by this embodiment, the current test result is determined before the function test of the test step is performed, so as to provide a guarantee for the subsequent function test, and if the test result fails, the test of the current test item is ended, so as to save the time for the flash test and improve the efficiency of the flash test.
On the basis of the above embodiment, the step S12 of executing the test case of the file to be flashed through a plurality of test steps under the current test item includes:
obtaining a test point of a current test item, wherein the test point is a forward test point and/or a reverse test point;
and performing flash writing on each test step according to the test points to execute the test cases of the files to be flash written.
Specifically, the test point of the current test item is obtained, and the pressure test is only a test means, and is a repeated test aiming at each test case under the condition of testing the forward test point or the reverse test point. The test points are test function points, mainly comprise functional key points of test requirements, are approximate description or rough test of a test scene, and do not comprise specific test data. The test site may have an indication of test pass or fail.
And performing flash writing on each test step according to the test points to execute the test cases of the files to be flash written. When the test point is a forward test point, the test steps are listed in sequence to realize the successful case flashing, and when the test point is a reverse test point, as an embodiment, when the test point is the reverse test point, the test case flashing according to the test steps of the test point to execute the file to be flashed comprises the following steps:
when the reverse test type is the skip flashing step type, executing the test case of the file to be flashed according to the skip test step corresponding to the skip flashing step type without executing, wherein the skip test step is a test step except the skip flashing step in each test step;
and when the reverse test type is a short circuit disconnection type, carrying out protection operation processing according to the test step corresponding to the short circuit disconnection type. It CAN be understood that the test types of the reverse test point include a power short circuit disconnection, a CAN short circuit disconnection, a type of skipping the flashing step, and the like, and under the abnormal condition of the power short circuit disconnection and the CAN short circuit disconnection, the corresponding operation is the operation for protecting the flashing process, so the power short circuit disconnection and the CAN short circuit disconnection are combined into the short circuit disconnection type.
And when the test type of the reverse test point is the skip flashing step type, executing the test case of the file to be flashed according to the skip test step corresponding to the skip flashing step type without executing the skip test step. With reference to the foregoing example of the embodiment, in a Flash process, the Flash steps are Flash clearing, data downloading request, data transmission, and push-out transmission, and if the Flash clearing step is skipped, the test steps corresponding to the data downloading request, the data transmission, and the push-out transmission are not skipped.
When the flash type is a short-circuit disconnection type, a step of automatic operation is added at a time when access is needed, the step of automatic operation is protection operation such as automatic power off in the embodiment, and the automatic operation is directly powered off as long as the power supply and the CAN line are tested to be abnormal. In the existing flash test, the operation of a power supply and a CAN line needs manual operation, so that the opportunity cannot be accurately grasped, and the test result is influenced. The automatic operation in the embodiment enables the action of the control power supply CAN line in the test case to be automated, and accurate action control and time control are achieved. It should be noted that when the test case performs the short-circuit disconnection type of the reverse test point, RS232 needs to be called to interact with the CAN bus and the power supply voltage, and control the CAN line short-circuit disconnection, the power supply input voltage, and the like.
Correspondingly, the operation test of the power supply and the CAN refers to a specific flash step in a normal flash process, for example, the power supply is disconnected when the set voltage exceeds the limit, or the power supply is short-circuited, or the CAN is short-circuited, disconnected and the like.
The embodiment provides according to the test point to each test step write by brush, when the test point is reverse write by brush test point, write by brush to each test step according to different reverse test types, guarantee the process of writing by brush orderly, short circuit breaking connection type when reverse test point simultaneously can realize accurate action control and time control, improves efficiency of writing by brush.

when the initial test results corresponding to the diagnosis function instruction are successful, determining that the test results are successful;
and when one result fails in the initial test result corresponding to the diagnosis function instruction, determining that the test result is a failure.
Specifically, the diagnosis function instruction is a send function instruction, a reply function instruction, or a check result function instruction, and the present embodiment provides only three types, and the actual diagnosis function instruction includes not only the three types, but also other diagnosis function instructions, which is only an embodiment and can be set according to actual situations.
And when the initial test results corresponding to the diagnosis function instructions are successful, determining that the test results are successful, and when the initial test results corresponding to the diagnosis function instructions are failed, determining that the test results are failed.
