Need some clarification with Test class

Hello Guys, 

I'm into a situation with a Test class , please help me to resolve it .

My Apex Code : -
public class Acc_dtls_nw 
{
    public String s;
    public integer i =0;
       
    public string acc_type_check(String Type_value)
    {
       string qry ='select count() from account where type=:Type_value';       
        i= database.countQuery(qry);
        if (i>0)
        {
           s='Total no of account Types are: '+i; 
        }
        else
        {
            s='Invalid type :';
        } 
              
          return s;     
         
    }}

I'm not able to get a 100% code coverage for this class. below part is not included under code coverage
 
 s='Total no of account Types are: '+i; 

Now the test class I wrote is below 
@istest
public class test_acc_dtls_nw 
{
     static testMethod void test_trucond()
    {
        Acc_dtls_nw ac= new Acc_dtls_nw();
        string tst_true = ac.acc_type_check('Prospect');
       // System.AssertEquals(ac.i,2);
        string p ='prospect';
       // System.AssertEquals(ac.s,p);      
    }
    
    static testMethod void test_flscond()
    {
        Acc_dtls_nw ac= new Acc_dtls_nw();
        string tst_flse = ac.acc_type_check('xyz');
       // System.AssertEquals(ac.i,0);        
    }
}

So why that part is getting missed under code coverage? is it because S is not doing anything and used just for strong some text value? please help me to get this clarified.

You need to insert an Account beacue test class do not have access to the database by default.

Use below test class. 
@istest
public class test_acc_dtls_nw 
{
     static testMethod void test_trucond()
    {
       Account acc = new Account(Name='Test Account', Type='Prospect');
        insert acc; // If some fields are rewuired then insert value in those fields as well.
        Acc_dtls_nw ac= new Acc_dtls_nw();
        string tst_true = ac.acc_type_check('Prospect');
       // System.AssertEquals(ac.i,2);
        string p ='prospect';
       // System.AssertEquals(ac.s,p);      
    }
    
    static testMethod void test_flscond()
    {
        Acc_dtls_nw ac= new Acc_dtls_nw();
        string tst_flse = ac.acc_type_check('xyz');
       // System.AssertEquals(ac.i,0);        
    }
}

Hi ,

Is that Acc_dtls_nw  class you created working properly? I checked in the method acc_type_check. Do you able to use that parameter  Type_value? I think you need to use something like this : string qry ='select count() from account where type=:'+Type_value;
