Following Points should be remembered during Testing process:

1.Always start with positive testing i.e, test for all the positive values according to requirements.

2.Continue with negative Testing i.e, test for all the possible negative values.

3.No exhaustive testing i.e, test engineer should not test repeatedly for similar kind of values.

4.No assumptions i.e, whenever the requirements are not clear then test engineer should not assume the requirements where as cross check with the concern person or get clarified with the concerned person.

5.No under testing i.e, whenever test engineer is doing testing he should always check for similar type of component or objects as well,if he don't test it is known as under testing.

Optimized Testing

Whenever a test engineer follows all the above mentioned points during testing process is know as optimized testing.
