Hello
Pls guide me in writing test class for the VF page.
​<apex:page standardController="Account"
           recordSetVar="accounts"
           tabStyle="Account"
           sidebar="false">
 
 <apex:pageBlock title="">
 
   <apex:repeat value="{!accounts}" var="a">
   
  <apex:pageBlockSection title="{!a.Name}"/>
 
  <apex:relatedList list="Contacts"
                    subject="{!a.ID}"
                    id="relatedlist1"
                    title="Contact Info"/>
 
 <apex:relatedList list="Opportunities"
                    subject="{!a.ID}"
                    id="relatedlist2"
                    title="Opportunity Info"/>
                  
</apex:repeat>
 </apex:pageBlock>
           
 
</apex:page>

@istest(SeeAllData=False)
private class MyCls_Test
{
    private static testmethod void testdata()
   {
          Profile p=[Select Id  from profile where name ='System Administrator'];
        
          User u=new User(ProfileId = p.Id, username = 'testmail@org.com', email = 'testuser@gmail.com',
        
                                        EmailEncodingKey = 'UTF-8' , LocaleSidKey = 'en_US',
                                      
                                        LanguageLocaleKey = 'en_US', timezonesidkey = 'America/Los_Angeles',
                                      
                                        alias='cspu',  lastname='lastname');
                
             System.RunAs(u)
            {
         }
}
