Test class code coverage - Syncing custom fields between quotes and opportunities (Custom Quote Sync)

Question

I have copied the code from the blog amitsalesforce for syncing custom fields from Opportunity Line Item to Quote Line Item on creation of Quote.

Made small changes in that code and that works fine for me. But when it comes to test class I get only code coverage of 70%. Below is the test class

@isTest

public with sharing class testTriggerOLISyncQLI{
    static testMethod void myUnitTriggerOLISyncQLI(){

                ));  

        insert qli;    
    }
}

The code didnt cover this part

Where am I missing ?? Suggestion please.

Looking at the blog, it updates and syncs the QLIs when the OLIs change. Your test class simply inserts a single oli and qli without ever updating either one of them. That's why the rest of the lines are never covered.

Also, you'll want to use testStartTest before you do your DML for oli and qli and then testStopTest when you're finished. Don't forget to add assertions to your test class to show that the changes made by the trigger were as expected.
