Post subject:	how to detect the error rate of a program
Hello, what is a good method to detect the error rate (defects per 1.000 loc) of a program? I'm aware of two methods: 1. needs data from two testers A and B which independently analysed the same code parts. If tester A observed m errors and tester B n errors, whereas k of the errors were observed by both testers, a rough estimate is (mn) / k problem: get data from at least two observers 2. artificially insert m bugs into source code analysed by testers. Assume x bugs were detected in total and z of them were artificial bugs, then the estimate is (x-z)(m/z) Jakob
