Automated testing advantages
n Permits quick and efficient verification of bug fixes
SLIDE 14
TA–14
Automated testing advantages – 2
n Permits quick and efficient verification of bug fixes n Speeds debugging and reduces “bad fixes”
SLIDE 15
TA–15
Automated testing advantages – 3
n Permits quick and efficient verification of bug fixes n Speeds debugging and reduces “bad fixes” n Allows consistent capture and analysis of test results
SLIDE 16
TA–16
Automated testing advantages – 4
n Permits quick and efficient verification of bug fixes n Speeds debugging and reduces “bad fixes” n Allows consistent capture and analysis of test results n Its cost is recovered through increased productivity and better
system quality
SLIDE 17
TA–17
Automated testing advantages – 5
n Permits quick and efficient verification of bug fixes n Speeds debugging and reduces “bad fixes” n Allows consistent capture and analysis of test results n Its cost is recovered through increased productivity and better
system quality
n More time to design better tests, rather than entering and
reentering tests

Automated testing advantages – 6
n Unlike manual testing, it is not error-prone and tedious
SLIDE 19
TA–19
Automated testing advantages – 7
n Unlike manual testing, it is not error-prone and tedious n Only feasible way to do regression testing
SLIDE 20
TA–20
Automated testing advantages – 8
n Unlike manual testing, it is not error-prone and tedious n Only feasible way to do regression testing n Necessary to run long and complex tests
SLIDE 21
TA–21
Automated testing advantages – 9

SLIDE 22
TA–22
Limitations and caveats
n A skilled tester can use his experience to react to manual
testing results by improvising effective tests
SLIDE 23
TA–23
Limitations and caveats – 2
n A skilled tester can use his experience to react to manual
testing results by improvising effective tests
n Automated tests are expensive to create and maintain
