13-Jul-15 Test Suites

Test classes A unit test is a test of an individual class By convention, we name test classes after the class that is being tested For example, if we have a Machine class, we would have a MachineTest class for testing it This is just a convention—we might have more than one test class for any given class Interfaces have no actual methods to be tested Abstract classes may have non-abstract methods that can be tested (and abstract ones that can’t) If a project has multiple classes, it makes sense to have a test class for each

Test suites A test suite is a class that contains calls to unit test classes (and sometimes other test suites) This is sometimes more convenient than running your unit tests one at a time Naturally, Eclipse will help you create a test suite Create your unit test classes File  New…  Other…  Java  JUnit  JUnit Test Suite Click the Next button to choose which unit tests to include in the suite If you add test classes later, you can hand-edit this suite Like the JUnit test classes, it’s just ordinary java

Example test suite (slightly edited) import junit.framework.Test; import junit.framework.TestSuite; public class AllTests { public static Test suite() { TestSuite suite = new TestSuite("Test for default package"); suite.addTestSuite(CodeMachineTest.class); suite.addTestSuite(ArrayCodeMachineTest.class); suite.addTestSuite(SimpleCodeMachineTest.class); return suite; }

Running the test suite Run the test suite just like any other unit test: Run  Run As  JUnit Test Results are very similar to those for a simple JUnit test
