| /** | ||
| * A test case defines the fixture to run multiple tests. To define a test case<br/> | ||
| * <ol> | ||
| * <li>implement a subclass of <code>TestCase</code></li> | ||
| * <li>define instance variables that store the state of the fixture</li> | ||
| * <li>initialize the fixture state by overriding {@link #setUp()}</li> | ||
| * <li>clean-up after a test by overriding {@link #tearDown()}.</li> | ||
| * </ol> | ||
| * Each test runs in its own fixture so there | ||
| * can be no side effects among test runs. | ||
| * Here is an example: | ||
| * <pre> | ||
| * public class MathTest extends TestCase { | ||
| * protected double fValue1; | ||
| * protected double fValue2; | ||
| * | ||
| * protected void setUp() { | ||
| * fValue1= 2.0; | ||
| * fValue2= 3.0; | ||
| * } | ||
| * } | ||
| * </pre> | ||
| * | ||
| * For each test implement a method which interacts | ||
| * with the fixture. Verify the expected results with assertions specified | ||
| * by calling {@link junit.framework.Assert#assertTrue(String, boolean)} with a boolean. | ||
| * <pre> | ||
| * public void testAdd() { | ||
| * double result= fValue1 + fValue2; | ||
| * assertTrue(result == 5.0); | ||
| * } | ||
| * </pre> | ||
| * | ||
| * 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. | ||
| * <pre> | ||
| * TestCase test= new MathTest("add") { | ||
| * public void runTest() { | ||
| * testAdd(); | ||
| * } | ||
| * }; | ||
| * test.run(); | ||
| * </pre> | ||
| * | ||
| * The dynamic way uses reflection to implement {@link #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. | ||
| * <pre> | ||
| * TestCase test= new MathTest("testAdd"); | ||
| * test.run(); | ||
| * </pre> | ||
| * | ||
| * The tests to be run can be collected into a TestSuite. JUnit provides | ||
| * different <i>test runners</i> which can run a test suite and collect the results. | ||
| * A test runner either expects a static method <code>suite</code> as the entry | ||
| * point to get a test to run or it will extract the suite automatically. | ||
| * <pre> | ||
| * public static Test suite() { | ||
| * suite.addTest(new MathTest("testAdd")); | ||
| * suite.addTest(new MathTest("testDivideByZero")); | ||
| * return suite; | ||
| * } | ||
| * </pre> | ||
| * @see TestResult | ||
| * @see TestSuite | ||
