Safety Critical Software - Test Coverage vs Remaining Faults

Licentiate Thesis

Abstract

Safety-critical software systems have traditionally been found in the aerospace-, nuclear- and medical domains. As technology advances and software complexity increases, such systems can be found in more and more applications, e.g. self driving cars. These systems need to meet exceptionally strict standards in terms of dependability. Proving compliance is a challenge for the industry. The regulatory bodies often require a certain amount of testing to be performed but do not require evidence of a given failure rate (which for software is hard to deal with compared to hardware). This Licentiate thesis discusses how to quantify test results and analyses what conclusions can be drawn from a given test effort, in terms of remaining faults in the software.
