Flex - FlexUnit Integration

Flash Builder 4對Flex開發周期中的FlexUnit集成提供了極好的內置支持。

Create a Test Case Class

可以使用Flash Builder創建測試類嚮導創建測試用例類。正如您將在本文中看到的，使用Flash Builder運行測試用例是輕而易舉的事情。

要使用Flash Builder創建測試用例類，請單擊「新建測試用例類」。輸入如下所示的詳細信息。

Flash Builder將創建以下TestClass1.as文件。

package com.tutorialspoint.client {
   public class TestClass1 {		
      [Before]
      public function setUp():void {}

      [After]
      public function tearDown():void {}

      [BeforeClass]
      public static function setUpBeforeClass():void {}

      [AfterClass]
      public static function tearDownAfterClass():void {}	
   }
}

FlexUnit Integration Example

現在，讓我們按照步驟在Flex應用程式中測試FlexUnit集成;

Step	Description
1	Create a project with a name HelloWorld under a package com.tutorialspoint.client as explained in the Flex - Create Application chapter.
2	Modify HelloWorld.mxml as explained below. Keep rest of the files unchanged.
3	Create TestClass1.as test case as described above and Modify TestClass1.as as explained below.
4	Compile and run the application to make sure business logic is working as per the requirements.

package com.tutorialspoint.client {
   import org.flexunit.asserts.assertEquals;

   public class TestClass1 {		
      private var counter: int = 1;

      [Before]
      public function setUp():void {
         //this code will run before every test case execution
      }

      [After]
      public function tearDown():void {
         //this code will run after every test case execution
      }

      [BeforeClass]
      public static function setUpBeforeClass():void {
         //this code will run once when test cases start execution
      }

      [AfterClass]
      public static function tearDownAfterClass():void {
         //this code will run once when test cases ends execution
      }      

      [Test]  
      public function testCounter():void { 
         assertEquals(counter, 1);
      }
   }
}

<?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 = "500" minHeight = "500">
</s:Application>

完成所有更改後，讓我們以正常模式編譯，就像在flex-create application一章中那樣。

Running Test cases

現在右鍵單擊package explorer中的TestClass1並選擇Run As>FlexUnit Tests。您將在Flash Builder測試窗口中看到以下輸出。

Flash Builder還會在瀏覽器中顯示測試結果。
