Examples of junit.framework.TestCase

junit.framework.TestCase
A test case defines the fixture to run multiple tests. To define a test case
1. implement a subclass of TestCase
2. define instance variables that store the state of the fixture
3. initialize the fixture state by overriding {@link #setUp()}
4. clean-up after a test by overriding {@link #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 {@link junit.framework.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 {@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.
```
 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; } 
```
