I like to share some definitions about TEST CASES ...

The most common definition of a test case is a set of conditions or
variables under which a tester will determine if a requirement or use
case upon an application is partially or fully satisfied. It may take
many test cases to determine that a requirement is fully satisfied. In
order to fully test that all the requirements of an application are met,
there must be at least one test case for each requirement unless a
requirement has sub requirements. In that situation, each sub
requirement must have at least one test case.

If the application is created without formal requirements, then test
cases can be written based on the accepted normal operation of programs
of a similar class. In some schools of testing, test cases are not
written at all but the activities and results are reported after the
tests have been run.

Under special circumstances, there could be a need to run the test,
produce results, and then a team of experts would evaluate if the
results can be considered as a pass. This happens often on new products'
performance number determination. The first test is taken as the base
line for subsequent test / product release cycles.
