Should it be so hard? The exact percent depends on the nature of the product, its complexity and expected life-cycle. But developers' work also brings cost, and—more importantly—testers' work also brings value. Overall, the term cost of quality (COQ) is a means to sum up product quality-related costs (control, detection, prevention) and defect-related costs (failure, non-conformance, deficiencies). Years of doing testing enables me to work out that a test of a particular complexity will take x hours of effort for preparation and execution. - how many features/functions Testing is regarded as the number one bottleneck in the software delivery process.
