A very simplistic method for estimating testing time can be as follows for a typical black box testing assignment
Total Time=No of cycles*(Time for each testing cycle+time for fixing of bugs found in one cycle)
so if you have an estimated time of testing cycle as 6 days and you expectthat the developers are going to take 4 days for fixing bugs found in one cycle and if the number of testingcycles are estimated as 4 then
Total time = 4*( 6+4)
Total time= 40 days
But this is very simplistic model but is useful for simpler projects |

A little more complex model for estimating software testing time involves
1 Categorizing Software Requirements resulting into number of requirements-they can cover business,technical,functional and performance
2 Using a Complexity Constant ( e.g 1 for simple and 1.5 for complex)
3 Applying Risk Factors (e.g ranging from 1.1 to 1.5)
4 Applying a General Contingency Factor (e.g 1.15-1.35)
so one cycle time =No of requirement*complexity constant*risk factor*contingency factor |
