Zusammenfassung:A system and method for collecting code coverage information relating to a fatal error path in a computer system. A fatal error operable to crash the computer system is instigated pursuant to executing a fatal error test module that exercises the fatal error path code, whose coverage is desired after the file system is rendered unavailable due to the crash. In response, a first dump file is created by the operating system kernel. Thereafter, a second dump process is launched to generate a second dump file which includes coverage information relating to the fatal error path code. After rebooting the computer system, an extractor is utilized to recover the code coverage information from the second dump file.
