Summary
It is generally difficult to measure the testing process or the testing team. Test Efficiency helps calculate how many defects were leaked to the customer as compared to number of defects reported by the testing team. Generally almost 10-15 percent of defects will be leaked and is considered acceptable. Recently, companies have started spending huge amounts of money for developing quality. Due to this, the defect leakage percentage has come down to less than 10 percent.
