Determining What to Test
You continue test planning by identifying test cases for your application. Each test
case describes a specific area of the application to test. Each area can encompass a
broad class of situations that you must test. For example, in testing a cash sales
transaction, you would probably test:
s
Valid input (the customer pays the exact price; the customer pays more and needs
change).
s
Invalid input (the customer pays less than the sales price; the sales clerk enters an
invalid part number).
So how do you determine what to test? This part of test planning test analysis and
design often requires you to rely on your own intelligence and experience, using
existing project assets as a reference.
When you design tests, the first step is to understand how the system is supposed to
behave. During analysis, you identify the conditions you must test to verify that:
s
The application does what is intended.
s
The application does not do what is not intended.
