PRINCIPLES OF FUNDAMENTAL TESTING

It is not possible. Instead, we need the optimal amount of

testing based on the risk assessment of the application.

It states that a small number of modules contain most of

the defects detected.

This is the application of the Pareto Principle to software

testing: approximately 80% of the problems are found in 20% of the modules.

Repetitive use of the same pesticide mix to eradicate insects during farming will

over time lead to the insects developing resistance to the pesticide Thereby

ineffective of pesticides on insects.

He must look out

continually to improve the existing methods to make testing more effective.

If the

same set of repetitive tests are conducted, the method will be useless for

discovering new defects.

the test cases need to be regularly reviewed & revised, adding

new & different test cases to help find more defects.

Software Testing reduces the

probability of undiscovered defects remaining in the software but even if no

defects are found, it is not a proof of correctness.

It is possible that software which is 99% bug-free is still unusable.

Testing should start as early as possible in the Software

Development Life Cycle.
