Flex4之测试框架--FlexUnit

1.先建一个类BankAccount.as

package test
{
	public class BankAccount
	{
		private var balance:Number=0;
		
		//存钱
		public function deposit(amount:Number):void{
			balance=balance+amount;
		}
		
		//取钱
		public function withdraw(amount:Number):void{
			balance=balance-amount;
		}
		
		//获取当前款项
		public function getBalance():Number{
			return balance;
		}		
	}
}

2.再创建BankAccountTest.as

package test
{
	
	import flexunit.framework.TestCase;
	
	public class BankAccountTest extends TestCase {
		
		/**
		 * Test Deposit
		 */
		public function testDeposit():void {
			var bankAccount:BankAccount=new BankAccount();
			bankAccount.deposit(50);
			assertTrue("Balance on a new account after 50 deposit is 50",bankAccount.getBalance() == 50);
			bankAccount.deposit(25);
			assertEquals("Balance after 50 deposit and another 25 deposit is 75",75,bankAccount.getBalance());
		}
		
		/**
		 * Test withdraw
		 */
		public function testWithdraw():void {
			var bankAccount:BankAccount=new BankAccount();
			bankAccount.deposit(100);
			bankAccount.withdraw(50);
			assertTrue("Balance on a new account after 100 deposit and a 50 withdraw is 50",bankAccount.getBalance() == 50);
		}
		
	}
}

3.然后创建一个mxml application : flexunit.mxml

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark" 
			   xmlns:mx="library://ns.adobe.com/flex/mx"
			   minWidth="955" minHeight="600"
			   xmlns:flexunit="flexunit.flexui.*"  
			   creationComplete="onCreationComplete()"
			   
			   >
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	
	<fx:Script>
		<![CDATA[
			import test.BankAccountTest; 
			import flexunit.framework.TestSuite; 
			
			// Create the test suite and run the tests 
			private function onCreationComplete():void 
			{ 
				testRunner.test = createSuite(); 
				testRunner.startTest(); 
			} 
			
			// Creates the test suite to run 
			private function createSuite():TestSuite { 
				var testSuite:TestSuite = new TestSuite(); 
				testSuite.addTestSuite(BankAccountTest); 
				return testSuite; 
			}    
		]]>
	</fx:Script>
	
	<!-- FlexUnit GUI Component -->  
	<flexunit:TestRunnerBase id="testRunner" width="100%" height="100%" />  
	
</s:Application>

4. 别忘了导入测试框架FlexUnit.swc
5. 运行flexunit.mxml就可以了，你会看到2个test都通过测试了。

备注：工程文件上传半天不成功，不过没关系，新建一个工程，新建上面3个文件，

? ??把FlexUnit.swc考进libs文件夹就可以运行了。

6运行效果如下所示：
