How to set up a negative test using eValid

Good Afternoon.

How does one set about doing a "negative test" -- one that proves that something is not true?

Any recommendations or suggestions?


Thanks

An interesting question ValBaum.

This is not an unusual situation.

Whenever a test reveals a behavior that is incorrect then that is a "negative test".

If you already have that script in hand, you're home free: you have a "negative" test right there.

The other part of your questions, how to prove that something is not true is a little bit more difficult.

Sorry, that is something of an understatement because to show something is NOT true in general is impossible.

Al you can really say is whether something specific is true or NOT true.

The point is, you have to have something SPECIFIC in mind and then testing techniques will let you confirm or deny if that SPECIFIC fact is OK.

A good example is, "validate selected text" -- this is a common thing to verify.

Here is the manual page for that command, which, in addition WAITS for that particular fact to be true.

Hope this helps!
