A method for automatically testing an apparatus controlled by software based on pilot test case file comprising user input sequence data recorded manually and the time stamp of the input. In the process of automated testing, these pre-recorded user inputs are replay with same input sequence but with either the same time interval between two subsequent inputs recorded prior; or with a random time interval autonomously generated in a range set by the test configuration. During the process of replaying user input, a separate plural numbers of background tasks are executed in parallel with random execution delays to generate varying system load and execution timing to simulate the apparatus' unpredictable real operation scenarios. The user input and new random time interval between each user input are recorded at replay as a new expanded test record file for later test result trace and failure analysis.

The invention discloses an automatic parking active braking test method based on CAN bus programming. The automatic parking active braking test method comprises a VCU (3), an ECU and an RTK (6) for controlling automatic parking. The VCU sends an automatic parking start instruction to the simulation brake test system (1); the simulation brake test system sends a no-brake request message to the EBS(5); and when the distance between the vehicle and the parking target point meets a distance threshold, the VCU sends a parking braking request to the EBS, the simulation braking test system switchesa message mode and sends a braking request message to the whole vehicle CAN network system (2), the whole vehicle CAN network system forwards the braking request message to the EBS, and the EBS executes braking operation to complete automatic parking. According to the invention, debugging of the control message of the whole vehicle controller can be avoided, the simulation brake test system is used for simulating a message receiving and sending function to realize pilot test and calibration of vehicle active braking performance and related functional parameters in the automatic parking process, and the development period is shortened.

A judgment unit judges the pass / fail of DUTs. A power supply circuit has changeable characteristics, and supplies a power supply signal to the DUTs. A condition setting unit performs a pilot test before a main test for the DUTs, and acquires a test condition to be used in the main test. The condition setting unit executes: (a) measuring a first device characteristic value for each of multiple pilot samples sampled from among the DUTs while emulating a power supply characteristic close to what is used in a user environment in which the DUT is actually used; (b) measuring a predetermined second device characteristic value for each of the multiple pilot sample devices while emulating a power supply characteristic close to what is used in a tester environment in which the main test is performed; and (c) determining the test condition based on the first and second device characteristic values.

A static pressure type powerful refrigeration hot air exchange system is adopted, the inside of the static pressure chamber is provided with an air cooler of a ceiling suspended refrigerator, and axial-flow ventilation fans arranged on the tops of the temperature gradient rooms and vertical air duct systems at four corners form a cold-hot air exchange general circulation. The ambient temperature of each temperature gradient room is automatically adjusted by adjusting the operation time of the fans. The tops of vertical air ducts at the four corners are all provided with air current one-way check valves to prevent hot air from flowing reversely into the static pressure chamber when the temperature gradient rooms supply the hot air. The cold store can meet different pilot-scale experiment requirements such as low temperature, high temperature and variable temperature for synchronously performing agriculture product fresh keeping, and can meet environmental conditions for simulating storage, transport, storage rack and common cold store precooling and perform fresh-keeping experiments under different atmosphere environmental conditions at the same time.
