There is provided a network join method including transmitting a long beacon message including transmission timing information of a first short beacon message to a child node network device, transmitting a first short beacon message including information regarding an interval in which it is possible to transmit a message, to the child node network device according to a transmission timing of the first short beacon message, receiving a slot allocation request message from the child node network device according to the interval in which it is possible to transmit a message, and checking whether the child node network device joins a network, and transmitting a slot allocation confirmation message to the child node network device.

Network join method and network device using the network join method

A fault-based software testing method and system are provided. The fault-based software testing method includes: generating a plurality of error programs by injecting faults into a testing target program; grouping the generated error programs into a plurality of groups with respect to respective test data, and selecting representative error programs with respect to the respective groups; and when an error is detected in the execution result of the representative error programs with respect to the corresponding test data, determining that errors are detected in all the error programs of the corresponding group.

Fault-based software testing method and system

Provided are a method and apparatus for evaluating the effectiveness of a test case used for a program test on the basis of error detection capability. The method includes: receiving a target program used for evaluating the effectiveness of the test case; generating an error program by inputting errors to the target program; detecting the errors by executing the test case on the generated error program; and calculating evaluation points of the test case using a ratio of the number of the detected errors to the number of the input errors. Thus, the capability of the test case used for a program test to detect errors can be evaluated.
