A New Process for Measuring and Displaying Board Test Coverage
Kenneth P. Parker · 2003
Board test coverage has for years been expressed as a percentage, for example, “98.2%”. However it is completely unclear what this measure really means. When the product development team, test department, and manufacturing were all within one company, these groups could comfortably define what coverage meant to them. Now it is more likely these functions reside in three different companies, and each works with different sets of people and tools every day. There is little chance these groups can effectively define their own definition of coverage. Now there is a compelling reason to agree on a common definition of board test coverage.
