Software Testing Principles

Below are some basic Software Testing Principles:

– A necessary part of a test case is a definition of the expected output or result.
– A programmer should avoid attempting to test his or her own program.

– A programming organization should not test its own programs.

– Thoroughly inspect the results of each test.

– Test cases must be written for input conditions that are invalid and unexpected, as well as for those that are valid and expected.

– Examining a program to see if it does not do what it is supposed to do is only half the battle; the other half is seeing whether the program does what it is not supposed to do.

– Avoid throwaway test cases unless the program is truly a throwaway program.

– Do not plan a testing effort under the tacit assumption that no errors will be found.

– The probability of the existence of more errors in a section of a program is proportional to the number of errors already found in that section.

– Software Testing is an extremely creative and intellectually challenging task.
