Test case are used to test the cogency of software.
Is ther anything to test the test cases i.e. validness of test cases?


if test cases are written for one version which have no more further development till next version then the person who knows complete functionality of the application can give training as well as based on documents one can write test cases which should be not 100% valid but yes fairly well atleast 80% valid then starts the process of verification of test cases and changes till the person(or group of persons) who knows functionality more and indulged into the application from the starting finally approves that...but here is one catch also you can't say the person who is working on the project from the starting know more than the person who joins that project newly...it all depends on the knowledge,intelligence,how you think and it changes from person to person....


What I personally feel the creator of test cases is the only person who can test the test cases for the validness.
If he understands the right requirement then the test cases written by him will be bug free.
let's take simple example:
if we have to test the sum of variable a and b.
to be very simple if a=3, b=2 then c = a+ b =5
if a=2.4 and b=1.4 then c=a+b = 3.8 but it's the requirement whether to take it as 3.8 or 4.
if a=1.4 b=2.1 then c= 3.5 and again it depends on requirement whether to take it as 3.5 or 3 or 4.
So all is the game of requirement and tester's mind, he is the only one who can test the test cases for it's validness.
Yesterday I was going through the topic "good test cases" and I read many post according to me good test cases are those wwhich converts the requiremnt correctly into test cases, whether the requirement provided to is right or wrong.
I also read there is no application which is bug free. Again this is wrong I have manually tested the application and it was delivered bug free and the application tested was connected through 27 interfaces.
