A TestCase is a collection of TestMethods that share a common test environment. When using FlexUnit4, each TestCase has a [Before] and [After] metadata tags that can be used to decorate methods you want to run before and/or after each test method. These metadatas simulate the setUp() and tearDown() methods of fluint and FlexUnit .9. So, for example, if you wanted to write a series of [TestMethods] to test the Flex Timer class, they could all exist in a single TestCase. In the method decorated with [Before] you would create a Timer instance to test use in your tests. In the method decorated with [After], you would stop that timer and remove references so it can be garbage collected.
Additionally, you may decorate any number of static methods per class with the medatadata [BeforeClass] and [AfterClass]. These methods will be run once per test class.

An example TestCase


package sampleSuite.tests
{
     import org.flexunit.Assert;

     public class TestCase1
     {		
          [Before]
          public function setUp():void
          {
          }
		
          [After]
          public function tearDown():void
          {
          }
		
          [BeforeClass]
          public static function setUpBeforeClass():void
          {
          }
		
          [AfterClass]
          public static function tearDownAfterClass():void
          {	
          }
		
          [Test( description="This tests addition" )]
          public function simpleAdd() : void
          {
               var x:int = 5 + 3;
               Assert.assertEquals( 8, x );
          }

          [Test( description="This tests subtraction" )]
          public function simpleSubtract() : void
          {
               var x:int = 5 - 3;
               Assert.assertEquals( 2, x );
          }


     }
