Introduction
We are aware that test cases are pivotal to any Test Plan. They help us discover information about the
product. According to IEEE Standard 610 Test cases are defined as “A set of test inputs, execution
conditions, and expected results developed for a particular objective, such as to exercise a particular
program path or to verify compliance with a specific requirement.” Another definition from IEEE
Standard 829 states that test cases are “Documentation specifying inputs, predicted results, and a set of
execution conditions for a test item.”
Let us now learn the different definitions of test cases. According to Ron Patton, “Test cases are the
specific inputs that you’ll try and the procedures that you’ll follow when you test the software.” Boris
Beizer defines a test as “A sequence of one or more subtests executed as a sequence because the
outcome and/or final state of one subtest is the input and/or initial state of the next.” The word ‘test’ is
used to include subtests, tests proper, and test suites.
Perhaps, a simpler definition is stated by Brian Marick, who calls the test case as test idea, where he
defines as follows, “A test idea is a brief statement of something that should be tested. For example, if
you're testing a square root function, one idea for a test would be ‘test a number less than zero’. The
idea is to check if the code handles an error case.”
