在Salesforce中编写Unit Test

Unit Test 也是一个 Class 文件，所以在创建 Unit Test 的时候要选择 Test Class 类型来创建，请看如下截图（在Eclipse中）：

 

编写 Unit Test 基本流程为：

　　1）：创建模拟数据。  

　　2）：调用Test.startTest方法。

　　3）：调用对应的我们所测试的方法。

　　4）：调用Test.stopTest()方法。

 

测试代码段一般会涉及到：测试属性，测试公共方法，测试静态方法，测试trigger。 请看如下代码段：

@isTest(SeeAllData = true)
private class EricSunUtilityTest {

    static testMethod void myUnitTest() {
    
        // first - what user profile are they? Sales Rep
        Profile p = [select id from Profile where Name = 'Sales Rep' limit 1];
        system.assert(p.id != null);
        User u = [select id, territory__c from User where ProfileId =:p.id and IsActive = true and territory__c != null limit 1];
        system.assert(u.id != null);
        
        //**---------  create test data ---------------------**//
        // create test data 
        Account a1 = new Account();
        a1.Name = 'Test Account001';
        a1.BDM_Owner__c = u.id;
        a1.Type = 'Prospect';
        insert a1;
        system.assert(a1.id != null);
        
        EricSunObject__c object1 = new EricSunObject__c();
        object1.Name = 'Test Object001';
        object1.OwnerId = u.id;
        object1.MyDate = date.newinstance(2011,7,1);
        
        system.runAs(u){

            Test.startTest();
          
            Test.setCurrentPage(Page.EricSunPage);    //set which page 
            EricSunController con = new EricSunController();    //init the 
          
            integer year = EricSunController.thisYear;     //test public variable
          
            //test special account owner
            ApexPages.currentPage().getParameters().put('uId',u.id);    //set the parameter
            con.ChangeOwner();        //test public function
          
            EricSunController.MyBillins_Target_All(u.id);    //test static function (Visualforce.remoting.Manager.invokeAction --> Remote Action)
            
            insert object1;
            system.assert(object1.id != null);    //test trigger about EricSunObject__c (insert)
            
            Test.stopTest(); 
        }
    }
}

 

编写完测试代码后，如何进行测试代码运行呢？请看如下过程：

Developer Console --- Test  --- New Run --- （Run Your Selected Test）

运行完之后，我们可以在 File --- Open 中选择对应的所测试的文件，来查看Unit Test 的覆盖率。

 

或者直接在Eclipse中运行对应的Class并且查看结果

Run Test 如下图所示：

 

View Result 如下图所示：

 

 

更加具体的细节，请详看如下链接:

http://wiki.developerforce.com/page/An_Introduction_to_Apex_Code_Test_Methods 

 

这里在简单的介绍一下 system.assert 的用法：

System.assert ---> 如果条件不满足将会抛出异常，通常我们不会在Trigger和Apex class中用到，但是在对应的Test中使用此方法是一个很好的处理方式
