A test case defines the fixture to run multiple tests. To define a test case

implement a subclass of TestCase
define instance variables that store the state of the fixture
initialize the fixture state by overriding setUp()
clean-up after a test by overriding tearDown().

Each test runs in its own fixture so there can be no side effects among test runs. Here is an example:

 public class MathTest extends TestCase {
    protected double fValue1;
    protected double fValue2;

    protected void setUp() {
       fValue1= 2.0;
       fValue2= 3.0;
    }
 }

For each test implement a method which interacts with the fixture. Verify the expected results with assertions specified by calling Assert.assertTrue(String, boolean) with a boolean.

    public void testAdd() {
       double result= fValue1 + fValue2;
       assertTrue(result == 5.0);
    }

Once the methods are defined you can run them. The framework supports both a static type safe and more dynamic way to run a test. In the static way you override the runTest method and define the method to be invoked. A convenient way to do so is with an anonymous inner class.

 TestCase test= new MathTest("add") {
    public void runTest() {
       testAdd();
    }
 };
 test.run();

The dynamic way uses reflection to implement runTest(). It dynamically finds and invokes a method. In this case the name of the test case has to correspond to the test method to be run.

 TestCase test= new MathTest("testAdd");
 test.run();

The tests to be run can be collected into a TestSuite. JUnit provides different test runners which can run a test suite and collect the results. A test runner either expects a static method suite as the entry point to get a test to run or it will extract the suite automatically.

 public static Test suite() {
    suite.addTest(new MathTest("testAdd"));
    suite.addTest(new MathTest("testDivideByZero"));
    return suite;
 }
