Specifically, as shown in fig. 2 of the specification, in response to the test start instruction, the step S103 of obtaining a corresponding upgrade package according to one of the OTA upgrade objects in the Adaptive automotive platform under test, that is, the step S includes:
s202, obtaining the information of the OTA upgrading object in the tested Adaptive AUTOSAR platform.
As described in step S103, before starting the test, the information of the OTA upgrade object is acquired, that is, the type of the OTA upgrade object is determined, or the OTA upgrade object is specifically acquired, and the subsequent selection and acquisition can be performed.
And S204, selecting and executing a corresponding test case in the test set according to the information of the OTA upgrading object.
And if one test case can be understood as a set of upgrading test flow corresponding to a certain OTA upgrading object, executing the test case, namely considering that the automatic test is carried out on the OTA upgrading object.
In this case, the test start instruction may be issued after the test case is selected and executed, or it may be considered that the test start instruction is not issued, and only the test case is acquired to start executing, and then the acquisition of the upgrade package may be automatically started to execute the automated test.
S206, selecting the corresponding upgrade package according to the test case for obtaining.

Specifically, in step S109, receiving the test log further includes:
and receiving the updated platform state information of the tested Adaptive AUTOSAR platform sent by the tested Adaptive AUTOSAR platform.
In this step, the updated platform state information may be obtained by some auxiliary programs in the Adaptive automotive architecture platform under test by monitoring the OTA upgrade test process; in a possible embodiment of the present specification, the obtained platform state information may also be understood as information contained in the test log, and may particularly include some information of the diagnosis result of the upgrade exception, and the OTA emulation test platform can visually display the information after receiving the information; for example, an upgrade test fails due to an abnormality in the upgrade test process, and the failure is caused by the fact that the simulation cloud interface is loosened, the Adaptive AUTOSAR platform to be tested cannot download the upgrade package successfully, and the information can be displayed intuitively; in addition, the state information of the tested Adaptive AUTOSAR platform after the upgrade test is completed can be checked after the platform state information is received, and further analysis and development are facilitated.
