S105, carrying out Adaptive preprocessing on the upgrade package according to the information of the Adaptive AUTOSAR platform to be tested.
The Adaptive preprocessing refers to the processing of enabling the upgrade package to be conveniently and rapidly received, downloaded, upgraded and installed by the Adaptive AUTOSAR platform to be tested, and can comprise a series of processing such as upgrade package selection, upgrade package encryption, upgrade package splitting and the like; in one possible implementation manner of the present disclosure, the upgrade package selection and obtaining in step S103 may also belong to one of the processing manners of the adaptive preprocessing.
S107, the upgrade package after the suitability pretreatment is sent to the Adaptive AUTOSAR platform to be tested so as to simulate the cloud sending process, and the Adaptive AUTOSAR platform to be tested performs OTA upgrade test according to the received upgrade package, generates a test log and sends the test log.
The upgrade package can be sent out through an analog cloud interface arranged in the OTA simulation test platform, and the analog cloud interface is connected with the tested Adaptive AUTOSAR platform to realize upgrade interaction between the two platforms.
S109, receiving the test log.
S111, generating a test report capable of reflecting the OTA upgrading test process according to the test log.
The test log is generated according to the process of monitoring the OTA upgrade test, and the test log contains information of the OTA upgrade test process, and specifically can comprise information of whether the OTA upgrade test process is successful, information of upgrade abnormality in the process, information of reasons for the upgrade abnormality, and the like; the information is sent back to the OTA simulation test platform, so that the information is generated into a test report to realize visual display, and clear test results are conveniently provided for testers, so that the testers can optimize the OTA upgrading function later.

Specifically, as shown in fig. 2 of the specification, the step S103 of obtaining, in response to a test start instruction, a corresponding upgrade package according to the OTA upgrade object in the Adaptive auto sar platform under test includes:
s202, obtaining information of the OTA upgrade object in the tested Adaptive AUTOSAR platform.
As described in step S103, before the test is started, the information of the OTA upgrade object, that is, the type of the OTA upgrade object is determined, or the specific party of the OTA upgrade object is obtained, so that the subsequent selection and obtaining can be performed.
S204, selecting and executing the corresponding test cases in the test set according to the information of the OTA upgrading object.
The test set is internally provided with a plurality of test cases in advance, one test case can be understood as a set of upgrading test flow corresponding to a certain OTA upgrading object, and then the test case is executed, so that the OTA upgrading object can be considered to be automatically tested.
In this case, the test initiation instruction may be issued after the test case is selected and executed, or the test initiation instruction may be issued without being issued, and the test case may be acquired to start execution, and then the upgrade package may be automatically acquired to execute the automated test.
S206, selecting the corresponding upgrade package according to the test case for obtaining.
Similar to the upgrade package, at least part of test cases respectively correspond to a plurality of OTA upgrade objects, namely, a plurality of built-in test cases are also used for upgrade test of the OTA upgrade objects, so that for a plurality of OTA upgrade objects to be tested in the Adaptive AUTOSAR platform to be tested, each OTA upgrade object can find a corresponding test case in the OTA upgrade object to perform automatic test so as to ensure normal and stable performance of upgrade test; it can be seen that the selection of the upgrade package corresponds to the test case, and the selection of the test case corresponds to the determined to-be-upgraded OTA upgrade object, which can be understood that during testing, the to-be-upgraded OTA upgrade object is determined first, then the test case is selected for execution, and finally the upgrade package is selected for obtaining.
Specifically, as shown in fig. 3 of the specification, in step S105, the performing Adaptive preprocessing on the upgrade package according to the information of the Adaptive auto sar platform to be tested at least includes:
s301, acquiring a corresponding dependency package from the upgrade package according to the dependency description in the upgrade package, wherein the dependency package is used for an OTA upgrade object in the tested Adaptive AUTOSAR platform to execute an installation operation.

S303, obtaining a differential calculation result, and dividing the upgrade package according to the differential calculation result to obtain an incremental upgrade package.
The step can also set a differential packet manufacturing module in the OTA simulation test platform for processing; the differential calculation is carried out by the OTA simulation test platform, the upgrade package is subjected to differential calculation after the upgrade package is obtained, if the upgrade package is larger (usually more than hundred megabytes) as shown by the check calculation result, the upgrade package can be divided into a plurality of small increment upgrade packages, and then the increment upgrade packages are sent, so that in the downloading process of the tested Adaptive AUTOSAR platform, if the condition that one increment upgrade package fails to be downloaded, the increment upgrade package can be downloaded again, the increment upgrade package which is downloaded successfully before is not required to be downloaded again, and the dividing process belongs to the division on an application layer instead of the division of a bottom communication protocol layer, so that the downloading speed is greatly accelerated, and the whole upgrading efficiency is improved; otherwise, once the upgrade package fails to download, the upgrade package needs to be downloaded again, and the downloading progress is greatly slowed down; if the result of the differential calculation shows that the obtained upgrade package is a smaller upgrade package, and the upgrade package is not split, the upgrade package after the differential calculation can be directly sent to the Adaptive AUTOSAR platform to be tested for downloading after the differential calculation is finished, so that the efficiency is higher.

Specifically, before the response to the test start instruction and the corresponding upgrade package is obtained according to the OTA upgrade object in the Adaptive AUTOSAR platform under test, that is, before the upgrade test starts, the method further includes:
and starting dynamic monitoring to dynamically monitor the process of the OTA upgrade test by the tested Adaptive AUTOSAR platform.
