Let me know if this class helps.
  
@isTest
private class AfterUpdateSNameTest{
	public static testMethod void AfterUpdateAssociatePeopleStaticTestMethod()
	{

		S__c objS =new S__c(Name='TestS' ,A__c='A' ,B__c='B', C__c='C',Status__c='Open');
		insert objS;

		R__c objR =new R__c(Name='TestR' ,A__c='A' ,B__c='B', C__c='C',Status__c='Open');
		insert objR;

		objS.Status__c = 'Approved';
		update objS;
	}

}

Hi Guna,

There are basic syntax / keywords like @isTest, @isTest(SeeAllData=true), startTest, stopTest, etc...

You need to learn all of them.

For code coverage improvment, I suggest reading your code, understand the logic flow and prepare test data accordingly.

For example, if you have a condition check like below. 
if(opp.StageName == 'Closed Won'){
  //Do stuff
}
else if (opp.StageName == 'Closed Lost'){
 //Do other stuff
}
else{
  //Do some other stuff 
}
These lines of code says that you need at least three opportunity records created (in your test data) with three different opportunity stages to get all three conditions covered.

More the number of conditions, more the number of test records to be created.

Does this make sense?

            R.Status__c ='Completed';
            update R;
          
    LogController.fromTrigger(sid); // this is new line (Here  "Logcontroller" is onemore new apexclass,in that class have method like "fromtrigger"that method calling here .when click on runtest shown error like this "Method doen't exist getcontact();")
        }
    }
}

Hi Guna,

This has to be an exception from the fromTrigger method. I cannot comment on it, unless I take a look at the code. 
LogController.fromTrigger(sid); // this is new line (Here  "Logcontroller" is onemore new apexclass,in that class have method like "fromtrigger"that method calling here .when click on runtest shown error like this "Method doen't exist getcontact();")
Also, you are passing an attribute called sid to the fromTrigger method (in the above line of code). Where are you getting it from?
