祝大家新年快乐,有任何问题可与我联系:点击这里给我发消息

       Flex单元测试与Junit有很大的不同,而Flexunit是用于flex的单元和集成测试的,编写测试代码之前首先到http://opensource.adobe.com/wiki/display/flexunit/Downloads去下载相应的flexunit包。

         在MyEclipse中右击工程,选择属性,选择”java build path”,选择第二个选项卡,将flexunit.swc加入到工程,单击“确定”,就可以编写相应的单元测试代码了。

        实例:新建要测试的文件:代码如下,这里使用的是ActionScript。

package test{
 public class BankAcount{
  private var balance:Number = 0 ;
  
  public function deposite(amount:Number):void{
   balance = balance + amount;
  }
 
  public function withdraw(amount:Number):void{
   balance = balance - amount;
  }
  
  public function getBalance():Number{
   return balance;
  }
 }
 
}

 package test{
 import flexunit.framework.TestCase;
 
 public class BankAcountTest extends TestCase{
  
  public function testDeposite():void{
   var bankAcount:BankAcount = new BankAcount();
   bankAcount.deposite(50);
   assertTrue("BankAcount on a new account is 50 after deposite 50",50,bankAcount.getBalance() == 50);
  }
  
  public function testWithDraw():void{
   var bankAcount:BankAcount = new BankAcount();
   bankAcount.deposite(100);
   bankAcount.withdraw(50);
   assertTrue("BankAcount on a new account is 50 after withdraw 50",10,bankAcount.getBalance() == 40);
   
  }
 }
}

新建一个mxml文件,用于运行测试:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="<a href="http://www.adobe.com/2006/mxml">http://www.adobe.com/2006/mxml</a>" layout="absolute"
 xmlns:flexunit="flexunit.flexui.*"
  creationComplete="onCreationComplete()">
 <mx:Script>
  <![CDATA[
      import flexunit.framework.TestSuite;
      import test.BankAcountTest;
   
    private function onCreationComplete():void{
     testRunner.test = createSuite();
     testRunner.startTest();
    }
   
    private function createSuite():TestSuite{
     var testSuite:TestSuite = new TestSuite();
     testSuite.addTestSuite(BankAcountTest);
     return testSuite;
    }
  ]]>
 </mx:Script>
 
 <flexunit:TestRunnerBase id="testRunner" width="100%" height="100%"/>
</mx:Application>

现在可以运行了,如果要测试的代码在mxml文件里也是可以运行的,更改testSuite.addTestSuite(BankAcountTest);括号里面的类名为mxml文件名就可以了。
