Patent attributes
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.
