Sample1__c (Id,Name,chkbox__c,Sum__c)
Sample2__c (Id,Name,Sample1__c,Num1__c)
Sample3__c (Id,Name,Sample1__c,Sample2__c,chkbox__c,Num1__c,Sum__c,Other_Field__c)
Sample1__c is the master of both Sample2__c and Sample3__c.
Meanwhile, Sample3__c has a lookup relationship with Sample2__c.
I have a requirement that updates a Sample3__c record after updating a Sample2__c record. Since Sample3__c is a child of Sample1__c, a field from Sample1__c record must be updated too. I am not encountering any problem with this requirement. In fact, it's working perfectly when I test it with data.
So in order to deploy it, I created a test class. Every time I run it, both the apex test execution ui and developer console are giving me passed result. But there is no code coverage.
I tried researching about this scenario, and there's this link: https://success.salesforce.com/issues_view?id=a1p30000000eMoyAAE
After following the instructions, there is still no code coverage. So, I am certain that the problem is in my codes.
I am kind of stuck here. Meanwhile, below are the codes.
Apex Class

s2List = [SELECT Id, Name, Sample1__c, Sample1__r.chkbox__c, Num1__c FROM Sample2__c WHERE Id IN: s2List];
List<Sample3__c> s3Qry = new List<Sample3__c>();
List<Sample3__c> s3ListToUpdate = new List<Sample3__c>();
for(Sample2__c s2 : s2List) {
s3Qry = [SELECT Id,Name,Sample1__c,Sample2__c,chkbox__c,Num1__c,Sum__c FROM Sample3__c WHERE Sample2__c =: s2.Id];
for(Sample3__c s3 : s3Qry) {
if(s2.Id != null) {
if(s2.Sample1__r.chkbox__c == true) {
s3.Sample2__c = s2.Id;
s3.Num1__c = s2.Num1__c;
s3.Sum__c = s2.Sample1__r.Sum__c;
s3ListToUpdate.add(s3);
