		//Get those records based on the IDs
		List<Account> accList = [SELECT Name FROM Account WHERE Id IN : accountIds];
		//Process records
	}
}

Test Class:

@isTest

Sample Code:

@isTest()
public class TestUtils {
    
    private static testmethod  void CreateAccount(){
        //Get Account Record Type Id
        Id accountRecordTypeId = Schema.SObjectType.Account.getRecordTypeInfosByName().get('DeveloperNameOfRecordType').getRecordTypeId();
        
        //Create Account
        Account acc = new Account();
        acc.Name ='Test Account';
        acc.Industry = 'Retail';
        acc.AccountNumber = '123456';
        acc.RecordTypeId = accountRecordTypeId;
        Insert acc;
    }
}

Test Class for Controller Extension

Apex Extension:

public class AccountExtension  {
    
    public Account acc {get; set;}
    
    //Constructor
    public AccountExtension(ApexPages.StandardController stdCtrl) {
        //Get Account Id
        Id accountId = stdCtrl.getId();
        
        //Get Account Required Information
        acc = [SELECT Id, Name, Business_Unit__c, Shipping_Country_Name__c FROM Account WHERE Id = : accountId];
    }
}

Apex Test Class:

@isTest()
public class TestUtils {
    
    private static testmethod  void CreateAccount(){
        
        //Create Account
        Account acc = new Account();
        acc.Name ='Test Account';
        acc.Industry = 'Retail';
        acc.AccountNumber = '123456';
        Insert acc;
        system.assertEquals(true,acc.Id != null);

        //Add Pagereference
        PageReference pageRef = Page.AccountPage;
        Test.setCurrentPage(pageRef);
        
        //Pass Standard controller Parameter
        pageRef.getParameters().put('Id', String.valueOf(acc.Id));
        String accountId = ApexPages.currentPage().getParameters().get('id');
        system.assertEquals(true, accountId != null);
        ApexPages.StandardController sc = new ApexPages.StandardController(acc);
        AccountExtension accExtn = new AccountExtension(sc);
    }

Test Class For Apex Trigger

Biswajeet   May 1, 2013   No Comments on Test Class For Apex Trigger

Here in below example the apex trigger is on “Account” object, to check duplicate Account Names.

Apex Trigger:

trigger AccountTrigger on Account (before Insert, before Update) {
     
    Map<String, Account> accMap = new Map<String, Account>();
     
    for (Account acc : System.Trigger.new) {
         
        //Make sure you don't treat account Name that isn't changing during an update as a duplicate.  
        if (System.Trigger.isInsert || (acc.Name != System.Trigger.oldMap.get(acc.Id).Name)) {
             
            //Make sure another new account isn't also a duplicate  
            if (accMap.containsKey(acc.Name)) {
                acc.Name.addError('An account already exist with same name.');
            } else {
                accMap.put(acc.Name, acc);
            }
        }
    }
     
    //Query to find all the Accounts in the database that have the same name as any of the Accounts being inserted or updated.  
    for (Account acc : [SELECT Name FROM Account
                        WHERE Name IN :accMap.KeySet()]) {
                            Account newAcc = accMap.get(acc.Name);
                            newAcc.Name.addError('An account already exist with same name.');
                        }
}

Here is the Test Class for the above apex trigger.
Test Class:

@isTest
private class TestAccountTriggers {

    static testMethod void AccountTriggerUnitTest() {
	
        Account acc1 = new Account();
        acc1.Name = 'ABC Corp Ltd';
        acc1.Type = 'Prospect';
        acc1.Industry = 'Banking';
        Insert acc1;
		
        Account acc2 = new Account();
        acc2.Name = 'ABC Corp Ltd';
        acc2.Type = 'Prospect';
        acc2.Industry = 'Apparel';
		
        try
        {
        	Insert acc2;
        }
        catch(System.DMLException e)
        {
        	System.assert(e.getMessage().contains('An account already exist with same name.'));
        }
    }
}
