salesforce 零基础学习（五十七）Test 类中创建TestUser帮助类

我们写Test Class的时候往往都需要指定一个uesr去run test method。

TestUserHelper类如下：

 public class TestUserHelper {
     public static User createUserByPermission(String permissionSetName) {
         Profile pfl = [select id from profile where name='System Administrator'];//the profile which you want to assign.
         //Declaring the User
         User runAsUser = new User(alias = 'Admin', email='admin@testorg.com',
                                   emailencodingkey='UTF-8', lastname='Testing', languagelocalekey='en_US',
                                   localesidkey='en_US', profileid = pfl.Id,  country='United States', CommunityNickname = 'u1',
                                   timezonesidkey='America/Los_Angeles', username='admin@xxx_org.com' );

         Insert runAsUser;
         PermissionSet pSet = [SELECT ID,Label from PermissionSet WHERE Name=:permissionSetName];
         PermissionSetAssignment Asign = New PermissionSetAssignment();
         Asign.AssigneeId=runAsUser.ID;
         Asign.PermissionSetId=pSet.ID;
         Insert Asign;
         Return runAsUser;
     }

     public static User createUserByPermissionAndProfile(String permissionSetName,String profileName) {
         Profile pfl = [select id from profile where name= :profileName];
         //Declaring the User
         User runAsUser = new User(alias = 'Admin', email='amin@testorg.com',
                                   emailencodingkey='UTF-8', lastname='Testing', languagelocalekey='en_US',
                                   localesidkey='en_US', profileid = pfl.Id,  country='United States', CommunityNickname = 'u1',
                                   timezonesidkey='America/Los_Angeles', username='admin@xxx_org.com' );

         Insert runAsUser;
         PermissionSet pSet = [SELECT ID,Label from PermissionSet WHERE Name=:permissionSetName];
         PermissionSetAssignment Asign = New PermissionSetAssignment();
         Asign.AssigneeId=runAsUser.ID;
         Asign.PermissionSetId=pSet.ID;
         Insert Asign;
         Return runAsUser;
     }

 }

里面有两个静态方法，一个是创建一个Profile为Admin，指定的Permission Set的User，一个是指定Profile，指定Permission Set的User。相关Test Class引用：

 @isTest
 private class TestUserClassUsingUserHelper {

     static testMethod void myUnitTest() {
         User testUser = TestUserHelper.createUserByPermission('your test permisson set name');
         System.RunAs(testUser) {
             Test.startTest();
             //TODO init data and operate like dml and assert etc
             Test.stopTest();
         }
     }
 }

总结：此篇方便以后自己写TestClass创建TestUser，有需要的可以直接用，有错误的地方欢迎指出。
