The common misconception about implementation of automation testing tools are
- Automating a system is expensive - Free tools & low cost automation tools are available in market.
- It can reduce manual testers - manual testers are required as they have the thorough application knowledge and without them test cases cant be written and without test case test scripts can't be generated.
- It can find more bugs - It is as good as running a written test case so its limited
- 100% automation can be done - On an average 70-80% automation can only be achieved as the tool itself has programming limitations.
