Unit Test Problem

Question

My Test class not covering all the code in this class plz help me to resolve this

Here it is my Class

public class emailCon1 {

    public map<string,string> m{set;get;}
    public list<contact> con{set;get;}

    public emailCon1()
    {
    m=new map<string,string>();
    con=[select lastname,email from contact];

         for(contact c:con)
         {
             m.put(c.email,c.lastname);
         }
    }
}

It is my Test Class

@isTest
public class emailCon1_Tc
{

    static testMethod void testMthd()
    {
        map<string,string> m=new  map<string,string>();
            contact c=new contact();
         emailCon1 ec1=new emailCon1();
          c.lastname='YYY';
         c.email='[email protected]';
        m.put(c.email,c.lastname);
    }
}

Answer 1

The reason you are not getting full test coverage is because you are not inserting the Contact record, so the code would not of been iterating over the for loop in your code.

This code should give you full test coverage:

@isTest
public class emailCon1_Tc
{
    static testMethod void testMthd() {
        String email = '[email protected]';
        String lastName = 'YYY';
        Contact c = new Contact(LastName = lastName, Email = email);
        insert c;
        emailCon1_Tc ec = new emailCon1_Tc();

        System.assertEquals(1, ec.con.size());
        System.assertEquals(c.Id, ec.con[0].Id);

        System.assertEquals(lastName, ec.m.get(email));
    }
}

This is the answer for my Question just 'seeAllData' made me to cover 100% code coverage thanks every one for helping me to resolve issue.

Here i covered NumberOfCons Trigger and emailCon1,emailCon classes

@isTest(seeAllData=true)

public class emailCon_Tc

{

  static testMethod void testMthd()

    {
        contact c=new contact();
        map<string,string> m=new  map<string,string>();
        set<string> e=new set<string>();        
        set<string> n=new set<string>();
         emailCon1 ec1=new emailCon1();
         emailCon ec=new emailCon();  
         c.lastname='YYY';
         c.email='[email protected]';
         insert c;

         c.lastname='YYYY';
         update c;
         delete c;
    }
}
