Hi,Community.

I have a test in the following code.

Test was Success,

But Test Code coverage is 0%.

 I want to 100% test coverage.

Please tell me what to do?

@isTest
public with sharing class LogACallControllerExtension {
    
    public Task task;
    
    ApexPages.Standardcontroller controller;
    
    public LogACallControllerExtension(ApexPages.StandardController controller) {
        this.task = (Task)controller.getRecord();
        User u = [Select Id From User Where id = :UserInfo.getUserId()];
//        List<Lead> lead = [Select Id,Email,Phone From Lead Where Lead.Id =:ApexPages.currentPage().getParameters().get('who_id')];
//        task.WhoId = lead[0].Id;
        task.WhoId = ApexPages.currentPage().getParameters().get('who_id');
        task.WhatId = ApexPages.currentPage().getParameters().get('what_id');
        task.Status = ApexPages.currentPage().getParameters().get('tsk12');
        task.OwnerId = u.Id;
    }
    
    
    public PageReference save() {
        Task t = new Task();
        t.ownerId = task.ownerId;
        t.status = task.status;
        t.subject = task.subject;
        t.whoId = task.whoId;
        t.activityDate = task.activityDate;
        t.Description = task.Description;
        insert t;   
        return null;
    }


static testmethod void LogACallControllerExtension(){
 
      Task task = new Task();
        task.ownerId = '005U0000000NadXIAS';
        task.status = 'Completed';
        task.subject = 'Call';
        task.whoId = '00QU0000002mMkw';
        task.activityDate = date.parse('2012/07/18');
        task.Description = 'test data';
      Insert task;

   PageReference pageRef = Page.instask;
   Test.setCurrentPage(pageRef);
        pageRef.getParameters().put('who_id','00QU0000002mMkw');
        pageRef.getParameters().put('tsk12','Completed');

   ApexPages.Standardcontroller std = new ApexPages.standardcontroller(task);
  LogACallControllerExtension lcall = new LogACallControllerExtension(std);
  Task TaskL = [select Id,description,ownerId,status,subject,activitydate from Task where activitydate = :date.parse('2012/07/18')];
  system.assertequals(TaskL.ownerId,'005U0000000NadXIAS');
  system.assertequals(TaskL.description,'test data');
  system.assertequals(TaskL.activitydate,date.parse('2012/07/18'));
  system.assertequals(TaskL.status,'Completed');
  system.assertequals(TaskL.subject,'Call');
 lcall.save();
 
}

}

Thanks.
