Testing does not ensure risk-free or bug-free software

Testing does not ensure risk-free software. There is nothing called hundred percent testing. Be it manual or automated testing but all testing is in a way manual (even in automated testing the test scripts are altered manually) and hence it is for sure that the testing will never be able to cover all possible test cases in a practical situation if compared to an ideal situation. Every time my team comes to me with a final report of bugs of any software tested, I am able to point out many cases that they say “yes, it should have been done! But we missed it or skipped it!”. Sometimes some cases or scenarios are intentionally dropped by the tester based on just his imagination that this case has no significant role. But if looked from another angle, the same intentionally dropped case appears to be a very important test case that is must to conduct to understand the result of an important behavior of the software. Like security, testing also does not ensure zero percent risk after it has been done. Only thing it ensures is minimizing the risks and vulnerabilities to the best possible level. Software Testing is the process to reduce or minimize the bugs or defects hidden in the software.

For further tips on how to achieve this you can go through my previously posted blog as “Twenty ways to ensure complete coverage of software testing”: http://itknowledgeexchange.techtarget.com/quality-assurance/
