In software development, a test suite, less commonly known as a validation suite, is a collection of test cases that are intended to be used to test a software program to show that it has some specified set of behaviors.
In model-based testing, one distinguishes between abstract test suites, which are collections of abstract test cases derived from a high-level model of the system under test, and executable test suites, which are derived from abstract test suites by providing the concrete, lower-level details needed to execute this suite by a program.
[2] An abstract test suite cannot be directly used on the actual system under test (SUT) because abstract test cases remain at a high abstraction level and lack concrete details about the SUT and its environment.
An executable test suite must work on a sufficiently detailed level to correctly communicate with the SUT and a test harness is usually present to interface the executable test suite with the SUT.
The testing subroutine would supply each number in the list to the primality tester, and verify that the result of each test is correct.
