Definition : The defect detection percentage (DDP) gives a measure of the testing effectiveness. It is calculated as a ratio of defects found found prior to release and after release by customers.Click to see full answer. Considering this, what is a defect ratio? Defect Rate and Defects Per Million The formula for defect rate is the amount of defective products observed divided by the number of units tested. For example, if 10 out of 200 tested units are defective, the defect rate is 10 divided by 200, or 5 percent. Defect rate is often stated in terms of defects per million. what is defect metrics in software testing? Software testing metrics or software test measurement is the quantitative indication of extent, capacity, dimension, amount or size of some attribute of a process or product. Example for software test measurement: Total number of defects. Beside this, how do you measure defects? Defect measures that are useful while work is in process (or pretty close) include: Defect Density is a measure of how many defects are in a piece of software during a defined period of development divided by the size of the module. Defect Discovery Rate is a count of the number of defects being discovered over time. How do you calculate defect rejection ratio? Defect rejection ratio: (No. of defects rejected/ total no. of defects raised) X 100. Defect leakage ratio: (No. of defect missed/total defects of software) X 100.
