It is the test data which causes the application to fail ..... much depends on test data itself....
@ Santosh : Application is never defect free.. testing can find defect but at no point of time, being a tester one can say that there are no more defects available in the system ....
samrat is correct..some inputs might work where as some other fail for the same.To over come that we do test with multiple test data
Testing application with Multiple data helps in covering maximum scenarios of the application ensuring all the scenarios are covered, testing with negative scenarios ensures no other bugs are raised.
