junit4 framework

every method name must start with "test" and no argument.

 

setUp();

tearDown();

 

1: extends TestCase   --------------run with junit framework

 

        public class A extends TestCase{
		public void test1(){}
	}

 

2 : use testSuite         ------------ run with java application, not junit framework

 

public class Main{
       public static void suite(){
			TestSuite suite = new TestSuite();
			suite.addTestSuite( A.class ); //--run all test case methods
			suite.addTest( new A("test1") ); //--run only parameter test1 method
			return suite;
		}
		public static void main(String[] args){
			junit.textui.TestRunner.run( suite() );
		}
	}

 

3: using annotation       -------- run with junit framework

the most convenient point is that you can define init something before all test case start and do something after all test case end.   extends TestCase can not do it.

 

public class annotationSample{
        @BeforeClass
	public static void beforeAllTestCase(){}
	@Test
	public void test1(){}
	@Test
	public void test2(){}
	@Before
	public void beforeEveryTest(){}
	@After
	public void afterEveryTest(){}
	@AfterClass
	public static void afterAllTestCase(){}
}

 

    the junit main will run class A and annotationSample test case , it is simple write style equals TestSuite

@RunWith(Suite.class)
@SuiteClasses({A.class,annotationSample.class})
public class Anno{

}
