Unit Test code coverage problem

Question

Here this is the class:

public class relatedList 
{

    public account acc{set;get;}
    public contact con{set;get;}    
    public string accname{set;get;}
    public void getdata() {
      acc=[select name,id from account where name=:accname];
      con=[select id,name,title,email,phone from contact where account.id=:acc.id limit 1];
    }

}

Here is Test Class which covers only 83% why not 100%? Showing error like list has no rows. Help me to resolve this.

@isTest

public class relatedList_TC

{

    static testMethod void testMthd()
    {
        relatedList rl=new relatedList();
        account a=new account(name='xxx');
        contact c=new contact(lastname='yyy',accountid=a.id);
        rl.getData();
    }
}

Answer 1

As the SOQL is filtering by accname, you need to set that field in your unit test. You also need to insert the objects in the test so they can be queried. So overall:

static testMethod void testMthd()
{
    account a=new account(name='xxx');
    insert a;
    contact c=new contact(lastname='yyy',accountid=a.id);
    insert c;

    relatedList rl=new relatedList();
    rl.accname = 'xxx';
    rl.getData();
    System.assertEquals(a.Id, rl.acc.Id);
    System.assertEquals(c.Id, rl.con.Id);
}

You should also add a "limit 1" to the Account query in your relatedList class because in production there could easily be multiple Accounts of the same name.

Answer 2

You need to insert your records within the test class, and then they will be available to the SOQL query:

static testMethod void testMthd()
{
    relatedList rl=new relatedList();
    account a=new account(name='xxx');
    insert a;

    contact c=new contact(lastname='yyy',accountid=a.id);
    insert c;

    rl.getData();
}
