Test Efficiency Vs Test Effectiveness

Test Efficiency Vs Test Effectiveness

S. No	Test Efficiency	Test Effectiveness
1	Test efficiency= internal in the organization how much resources were consumed how much of these resources were utilized	Test effectiveness = how much the customer's requirements are satisfied by the system how well the customer specifications are achieved by the system how much effort is put in developing the system
2	Number of test cases executed divided by unit of time (generally per hour).	Number of defects found divided by number of test cases executed.
3	Test efficiency = (total number of defects found in unit+integration+system) / (total number of defects found in unit+integration+system+User acceptance testing)	Test effectiveness = (total number of defects injected +total number of defect found) / (total number of defect escaped)* 100
4	Test Efficiency: Test the amount of code and testing resources required by a program to perfirm a function	Test Effectivness: It judge the Effect of the test enviornment on the application
5	Testing Efficiency = (No. of defects Resolved / Total No. of Defects Submitted)* 100	Test Effectiveness = Loss due to problems / Total resources processed by the system
6	Test Efficiency is the rate of bugs found by the tester to the total bugs found. Let me explain it more clearly: When the build is sent to the customer side people for the testing (Alpha and Beta Testing), the customer side people also find some bugs. Test Efficiency = A/(A+B) Here A= Number of bugs found by the tester B= Number of bugs found by the custome side people This test efficiency should always be greater than 90%
