       How to write good test cases

As distant as possible, write test cases in such a style that you test only one thing at a time.
Do not overlap or impede test cases. Attempt to make your test cases ‘atomic’.

•       Ensure that all conclusive scenarios AND adverse scenarios are covered.

•       Language:

Ø  Write in simple and easy-to-understand language.

Ø  Use active voice instead of passive voice: Do this, do that.

Ø  Use  identical and consistent names (of forms, fields, etc).

 Characteristics of a good test case:

Ø  Accurate:                Exacts the purpose.

Ø  Economical:            No unnecessary steps or words.

Ø  Traceable:               Capable of being traced to requirements.

Ø  Repeatable:            Can be used to enforce the test over and over.

Ø  Reusable:                Can be reused if necessary.

Ø  Identifiable:            Easily identifiable with its name;

Ø  Bug Finder:            Allows isolation and identification of defects
