Automation is usally used for productivity improvement and
cost saving. So following facts are pimarily considered.
1)ROI(return on investment) is huge.
2)When same set of test cases needs to be executed for many
number of times.
ROI Calculation:
(Say to execute a test case manually if it takes 20 mins
and the same test case should be executed for next 5
releases it takes 100(20*5=100) mins. Now to generate
Automation script takes 50mins and to execute each time
takes 2 mins so 2* 5 times = 10 mins , so totally it takes
only 60 mins, thereby saving 40 mins). Here we go for
automation. The numbers said here is less for examples. it
makes huge difference if we just convert mins into Hrs.
In Manual:
20Hrs * 5 times = 100Hrs
In Automation
2hrs * 5 times = 10Hrs + 10Hrsscripting time = 20Hrs.
There by saving 80Hrs(100-20=80) by automating.
Per hour if the customer is charging $20 to a comapany the
company is saving 20*80 = $160 which is profit to the
company.
