Testing Limitations

You cannot test a program completely
We can only test against system requirements
- May not detect errors in the requirements.

- Incomplete or ambiguous requirements may lead to inadequate or incorrect testing.

Exhaustive (total) testing is impossible in present scenario.
Time and budget constraints normally require very careful planning of the testing effort.
Compromise between thoroughness and budget.
Test results are used to make business decisions for release dates.
Even if you do find the last bug, you’ll never know it
You will run out of time before you run out of test cases
You cannot test every path
You cannot test every valid input
You cannot test every invalid input
