Hi

Try the code below: 
@isTest
public static void testMethod1()
{
List<Account> accList=new List<Account>();
for(int i=0;i<10;i++)
{
Account acc=new Account(name='test Account');
accList.add(acc);
}
insert accList;

LDS_PaginationController.getAllRecords('1','5');
LDS_PaginationController.getPageCountChange('5');
LDS_PaginationController.getPageCountInfo('1','2','5'); //give the values based on the else if conditions --call the method multiple times to satisfy all teh conditions
}
