Abstract: A system and a method for automatically testing embedded system software and a method for constructing a test scenario are provided to reduce test consumption time and to enhance correctness by automating construction various user test scenarios and the test of the embedded system software at each target system. A method for automatically testing an embedded system software comprises the following several steps. An event management engine sets up a test environment at a target system(S610). The event management engine accesses an event agent of the target environment(S620). The event agent reads a test event stored at an event & message repository of a host system, and execute the event by a scheme that a signal generated when there occurs the event is inputted to an equipment driver(S630), and then storing a message, generated at a test program installed at a target system, at the event & message repository of the host system(S640). If all the events are determined to be completed(S650), a result message stored together when the host system constructs a scenario is compared with a message generated by the test program after the target system executes the scenario(S660).

Abstract: A method and an apparatus for managing out-of-memory in an embedded system are provided to provide a flexible algorithm for processing the out-of-memory according to a memory usage behavior of an application program. A method for managing out-of-memory comprises the following several steps. A user sets an available memory threshold and an out-of-memory management policy including an out-of memory algorithm and a protection process selection via a policy setup module, and registers the set memory management policy at an operating system(S320). If a new process requests memory assignment during system operation(S330), a management apparatus checks an available memory by using the inputted available memory threshold(S340). If the threshold of the available memory is larger than a requested memory amount of the new process, the apparatus assigns the requested memory to the new process(S345). If the threshold of the available memory is smaller than a requested memory amount of the new process, the apparatus recognizes the out-of-memory and executes the out-of-memory management algorithm(S350). The apparatus selects a sacrifice process according to the selected out-of-memory management algorithm(S360). The apparatus terminates the selected sacrifice process and gets back the memory used by the sacrifice process(S370), and checks the available memory.
