Chitral Chadda test class issue
I have a trigger which displays list of contact address on account
suppost i hav accnt a1 and related contact as c1, c2
there addres_for_contact__c field on contact
and final_address_of_contact__c field on account
if for c1 ...addres_for_contact__c='a';
for c2 ..addres_for_contact__c='b';
then on account ..final address of contact = a,b
when i do run test it shows pass : but there is 0 % code coverage
i m unsure what cud b d reason

you are already updating the value of the address in acc with the required
value which is not needed.
What should happen is:
You create the account(correct)
insert the account(correct)
You create the contacts(correct)
insert the contacts(correct) >> This line will call the trigger and auto update the value of address field in the acc such that you need not again update it in the test method.
All you need to do next is:
run an SOQL to get the address field on the acc:
account updt =[ select id,Final_address_of_contacts__c from account where id=:acc.id];
and compare it to the values of the contact address, something like this:
system.assertEquals("<contact1 address>,<contact2 address>", acc.Final_address_of_contacts__c);
