Abstract: PURPOSE: A method for automatically creating a test case for testing an object-oriented chill program is provided to create a sequence of complete member functions by extracting information for testing an interactive operation between objects from an MSC(message sequence chart) detail and extracting information for testing an interactive operation in the objects from an SDL(specification and description language) detail, thereby combining the information. CONSTITUTION: A BMSC(basic message sequence chart) detail is created by applying a test standard to a HMSC(hybrid message sequence chart) detail. A test driver is constructed by combining an event sequence extracted from a BMSC detail, a call of a member function extracted from the SDL detail and a synchronized sequence. The wanted test case is extracted by applying a test standard from the test driver.

Abstract: A wavelength tunable light source device integrated with an optical amplifier, a beam steering unit and a concave diffraction grating is provided to remove additional optical components or optical alignment by integrating optical components of a bulk type structure. An optical amplifier(102) amplifies a beam. A beam steering unit(104) moves a path of the beam outputted through the optical amplifier by an electric signal. A concave diffraction grating(106) diffracts and reflects the beam incident from the beam steering unit to have a specific wavelength according to the beam angle. The beam generated in the optical amplifier changes the beam path as the electric signal is applied to the beam steering unit and then is incident on the concave diffraction grating, and the beam having the specific wavelength by the concave diffraction grating is fed back to the optical amplifier, and the wavelength of the beam is tuned by the beam steering unit.
