Abstract
Abstract A method, and associated circuitry, for testing operation of computer software of a computer system, such as a telephonic switch system. The computer system may be installed and optionally on-line while the computer software is being tested. Multiple portions of the computer software are executed while the computer software is under test. Selected portions of the computer software are tested in interpreted form. Remaining portions are executed more quickly in compiled form. Therefore, line-by-line execution of only portions of the computer software is required during testing of the entire computer software. The selected portions may be selected, for example, either manually during run-time or automatically based on commands within the code of the computer software. In another embodiment of the invention, the line-by-line interpreted testing of portions of the computer software is conducted with a computerized emulator.
