Zitiert aus dem Werk von Glenford Myers, ``The Art of Software Testing'':
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 own
program.
| |
A programming organization should not test its own
programs.
| |
Thoroughly inspect the results of each test.
| |
Test cases must be written for invalid and unexpected,
as well as valid and expected, input conditions.
| |
Examining a program to see if it does not do what it
is supposed to do is only half of the battle. The other
half is seeing whether the program does what it is not
supposed to do.
| |
Avoid throw-away test cases unless the program is
truly a throw-away 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.
