創建user，這些是必填的
Profile saleProfile = [ select id from Profile where Name = '市場部人員'];
List<User> userList = [select id,ProfileId,Alias,TimeZoneSidKey,LocaleSidKey,
LanguageLocaleKey,EmailEncodingKey from User where id =:UserInfo.getUserId()];
User u = new User();
u.Username='[email protected]';
u.LastName='supUser';
u.Email='[email protected]';
u.Alias=userList[0].Alias;
u.TimeZoneSidKey=userList[0].TimeZoneSidKey;
u.ProfileId=saleProfile.Id;//簡檔
u.LocaleSidKey=userList[0].LocaleSidKey;
u.LanguageLocaleKey=userList[0].LanguageLocaleKey;
u.EmailEncodingKey=userList[0].EmailEncodingKey;
u.CommunityNickname='supUser';
insert u;
//新創建的用戶，作爲測試對象
system.runAs(saleUser)
