how to write test class of my code

can you please me to write test class on below code:
Apex code:

public class copycontact {
    public list<selectoption>account1{set;get;}
    public list<selectoption>account2{set;get;}
    public list<contact>contacts{set;get;}
    public String getListOfAccounts { get; set; }
    public id selectedaccountId1 {set;get;}
    public id selectedaccountId2 {set;get;}
    public list<id>selected ;
    public List<SelectOption> getListOfAccounts1()
    {
        List<Account> AccountList1 = [select id,Name from Account] ;
        System.debug('Accounts'+AccountList1.size());
        account1 = new List<SelectOption>();
        account1.add(new SelectOption( ' ' ,'---Select---'));
        for(Account acc : AccountList1 )
        {
            account1.add(new SelectOption(acc.id , acc.Name));
        }
        return account1 ;         
    }
    public List<SelectOption> getListOfAccounts2()
    {
        List<Account> AccountList2 = [select id,Name from Account] ;
        System.debug('Accounts'+AccountList2.size());
        account2 = new List<SelectOption>();
        account2.add(new SelectOption( ' ' ,'---Select---'));
        for(Account acc : AccountList2 )
        {
            account2.add(new SelectOption(acc.id , acc.Name));  
        }
        system.debug('java');
        return account2 ;  
    } 
    public  void clonecontacts(){
        system.debug('gsvdd');
        if(selectedaccountId1!=null){
            contacts=new list<contact>([select id,lastname from contact where accountid=:selectedaccountId1]);
            if(contacts.size()==0){
                system.debug('gsg'   );
               ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.Error,'No contacts to display'));
            }
            else{
                system.debug('dhg');
                list<contact>clist=new list<contact>();
                for(Contact con:contacts){
                    contact c=new contact();
                    c.lastname=con.LastName;
                    c.AccountId=selectedaccountId2;
                    clist.add(c);
                }
                insert clist;
                ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.CONFIRM,'successfully copied'));
            }
        }
    }
}
vf page:

I will recommend you to start using trailhead to learn about test classes
1) https://trailhead.salesforce.com/modules/apex_testing

Pleasse check below post sample test class
1) http://amitsalesforce.blogspot.com/2015/06/best-practice-for-test-classes-sample.html

Also please check below post
1) https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_qs_test.htm
2) https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_testing_example.htm

You write a test class for this the same way that you would any other:
Set up some data for the controller to access (in this case it looks like Account ,Contact and Opportunity)
- Instantiate the controller - as its custom you don't need to pass any parameters
- Execute a method/methods
- Verify the behaviour with asserts.

Sample Test class for you to start
@isTest
private class copycontactTest {

    static TestMethod void myUnitTest()
	{
		Account acc = new Account();
			acc.Name ='Test';
			// Add all required field
		insert acc;
		
		Contact cont = new Contact();
			cont.LastName ='Test';
			cont.accountId = acc.id;
		insert cont;
		
		Opportunity testOpportunity = new Opportunity(
	            Name = 'Test Opportunity Triggers',
	            CloseDate = '2016-01-01',        
	            StageName = 'Sourcing Demand',
	            accountId = acc.id,
				copyContact__c = cont.id
        );
		insert testOpportunity;
		
		Test.startTest();
			copycontact  obj = new copycontact ();
			List<SelectOption> lstAccSelectOpp1 = obj.getListOfAccounts1();
			List<SelectOption> lstAccSelectOpp2 = obj.getListOfAccounts2();
			
			obj.clonecontacts();
			obj.selectedaccountId1 = acc.id;
			obj.clonecontacts();
				
			
		Test.stopTest();
    }
}


 

Please follow below salesforce Best Practice for Test Classes :-

1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with testMethod keyword .
5. To deploy to production at-least 75% code coverage is required 
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the  percentage of code coverage ,we should make sure that every use case should covered including positive, negative,bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger ,class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase :-Not to add future date , Not to specify negative amount.
Restricted User :-Test whether a user with restricted access used in your code .
10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method  is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private ,no matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't  send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method  and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
26. Maximum number of test classes run per 24 hour of period is  not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process .

1.insert the list of accounts
2.call all the methods.

sample code 
@isTest 
public class copyContactTest
{
	static testMethod void testMethod1() 
	{
		Account testAccount = new Account();
		testAccount.Name='Test Account' ;
		insert testAccount;
		
		Contact cont = new Contact();
		cont.FirstName='Test';
		cont.LastName='Test';
		cont.Accountid= testAccount.id;
		insert cont;
		
		Test.StartTest(); 
			copyContact obj = new copyContact();
			obj.getListofccounts1();
                        obj.getListofccounts2();
                        obj.cloneContacts();
			obj.selectedAccountId = testAccount.id;
			obj.viewContacts();
			
		Test.StopTest();
	}
}



your code get 100% coverage

thank you but it cover 60% code only

vijay kumar kvijay kumar k
thanks its working. can u help me to how i think to write test classes
vijay kumar kvijay kumar k
i think u understood what is my senario.
I have to make changes on my senario i.e in case that inserted contacts have some child opportunities (i create custom loocup relationship between contact and opportunities) ,that opportunities also insert as another account.
so please help me write code

ok help me to write test class of this code
public class copycontact {

Thank you amit sir, from now i will follow the above instructions for test classes.
If u don't mind tell me last one about this test class. This test cover 88%of code so  please help me to solve it.

What help you need ? Code coverage is 88% which is a good number
