Components

nFixture

–Configured instance of class to be tested

nTest case

–Stimulus used for the test

nCheck

–Code to check results of the test

nTest suite

–Collection of tests


	Here’s a list of some of the components needed for the tests.

	In the example there really isn’t a fixture, since there are only class methods and no variables. If you were testing sets, an example would be the empty set or the set of even numbers less than 100.

	The test case in the example is really the collection of maximum values 0, 2, 3, and 100.

	Results are often checked with assertion statements. In Java there is an assertEquals method, but Smalltalk often uses should: and shouldnt:

	Lastly, tests can be grouped together into test suites. In this example, the test suite is generated automatically using language reflection capabilities, but it is also possible to make suites in code.
