Automated testing


Test automation is the use of software to control the execution of tests, the comparison of actual outcomes to predicted outcomes, the setting up of test preconditions, and other test control and test reporting functions. Commonly, test automation involves automating a manual process already in place that uses a formalized testing process.


The  principle of automated testing is  that there is a program (which could  be a job stream) that runs the program being tested, feeding it the  proper input, and checking the output against the output that was expected.  Once  the  test suite is written,  no human intervention is needed,  either to run the program or to look to see if it worked; the test  suite  does  all  that,  and somehow indicates  (say, by a :TELL message  and  a  results  file)  whether  the program's  output was as
expected.  We, for instance, have over two hundred test suites, all of which  can  be  run  overnight by executing  one job stream submission command;  after  they run, another command  can show which test suites succeeded and which failed.

ADVANTAGES
Automated Testing
Manual Testing

• If you have to run a set of tests repeatedly automation is a huge gain

• If Test Cases have to be run a small number of times it's more likely to perform manual testing
• Helps performing "compatibility testing" - testing the software on different configurations • It allows the tester to perform more ad-hoc (random testing)
• It gives you the ability to run automation scenariosto perform regressions in a shorter time • Short term costs are reduced
• It gives you the ability to run regressions on a code that is continously changing • The more time tester spends testing a module the grater the odds to find real user bugs
• Can be run simultaneously on different machines thus decreasing testing time  
• Long term costs are reduced  
DISADVANTAGES
Automated Testing
Manual Testing
• It's more expensive to automate. Initial investments are bigger than manual testing • Manual tests can be very time consuming
• You cannot automate everything, some tests still have to be done manually • For every release you must rerun the same set of tests which can be tiresome
OTHER FACTORS
• The performance of yout test tools
• The knowledge level of your testing team
• The continous growth of software to be tested
• Number of necessary regressions
