This paper describes a software testing program for an airborne guidance system that includes two levels of on-line functional testing, diagnostics, field funneling capabilities, automatic data output for off-line analysis, field-test bypass and repair capability, and the ability to determine the long-term effect of aging on the unit under test. It is estimated that these features require approximately 20 t0 25 percent additional code and approximately 20 to 15 percent more test design and debug time than would have been necessary for 100-percent functional tests. The total testing software consists of fewer than 35 k 24-bit words of code. Design decisions, software-packaging decisions, test generation methods, and validation and verification methods used in the design and development of the software program are discussed briefly.
