Testing Apex class and code coverage

Hello all,
I apologize if this is a repeat, but I am very new to SFDC Apex Code.  I have an apex class in Sandbox that I am trying to migrate to production.  I get the code coverage error (my class currently shows "no coverage" in sandbox).  I am reading about testing, but unsure how it all ties together to create a deployable inbound change set in prod.

the code I have is as follows:
public class AssignLeadsUsingAssignmentRules
{@InvocableMethod     public static void LeadAssign(List<Id> LeadIds)    
{Database.DMLOptions dmo =
new Database.DMLOptions();dmo.assignmentRuleHeader.useDefaultRule= true;
Lead Leads=
[select id from lead where lead.id in :LeadIds]; Leads.setOptions(dmo); update Leads;    } }

again, being new to this, I thought adding "@istest" to the beginning would do the trick.  sounds like it's a little more involved than that?

any help is greatly appreciated.
thank you.

Hello, 

Use below Test method for you Class.. Code Coverage 100%
 
@isTest
Public class AssignLeadsUsingAssignmentRules_Test
{
static testMethod void testLeadAR() 
    {
  Lead TestLead= new Lead();
  TestLead.LastName ='TestLastName';
  TestLead.Company ='TestCompany';
  TestLead.status ='Lead-Contactd';
  insert TestLead;
  list<id> listids= new list<id>();
  listids.add(TestLead.id);
   
   
        Test.StartTest();                  
        AssignLeadsUsingAssignmentRules.LeadAssign(listids);
        Test.StopTest();
        
        }
}

Hi Erik Peterson 20,

I hope you will get a good code coverage with Karthik test class. If you want to learn the test class and want some sample test classes then please check below post
1) http://amitsalesforce.blogspot.com/search/label/Test%20Class
2) http://amitsalesforce.blogspot.com/2015/06/best-practice-for-test-classes-sample.html

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 .

This worked great! I have 100% coverage in Sandbox. I will most definitely mark as best answer. Thank you!!! On a side note, when I attempt to migrate to production, it fails and I am perplexed. Code coverage for a trigger in our production, but nothing I wrote. Also “missing required field”, Company. I may turn ALL validation rules off, and try again. I’m going to peruse the community for tips on successful migration. Any further assistance is greatly appreciated.

Migration to Production error
Erik John PErik John P
Thank you Karthik, So are you saying the trigger we have in production (ELQA_LeadConvert_Update_Marketing_Trigger) needs a test class created in sandbox before I can deploy my apex class? Is it possible for me to somehow “deactivate” that trigger before importing my apex class?

Erik John PErik John P
Thank you! Again, I apologize for all the questions. But perhaps an obvious one: When I import the original apex class with the change set, am I supposed to import both the apex class and the test?

Hello Karthik, I’ve got code coverage now, but another issue is perplexing me. Getting an error that states: ELQA_Leadconvert_updateTest positivetest System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Company]: [Company] Stack Trace: Class.ELQA_Leadconvert_updateTest.positivetest: line 10, column 1 ELQA LeadConvert_updateTest has COMPANY in it, so I’m not sure why we’re getting this error. ELQA LeadConvert test class has the following snippit of code…company is in there. static testmethod void positivetest() { Lead testlead = new Lead(); testlead.firstname = 'test first'; testlead.lastname = 'test last'; testLead.company = 'Test Co'; testLead.email = 'test@gmail.com'; TestLead.TS_Factory__c ='TS00020'; // added all required field here As always, any guidance is helpful!

Hello again Karthik, A follow up with a bit more info as I’m looking at it. Thank you so much for assistance if you can provide it. No problem if not. Receiving error on validation of import to production – Required field missing [Company]. Error refers to “line 7 and line 29” in the test class, “TestLeadTriggerActions”. Those lines call a different test class “TestDataUtil”. So I’m missing “company” from TestDataUtil, just not sure where to put it. Here’s the code for “TestDataUtil”: public with sharing class TestDataUtil { //create Accounts public static List createAccounts(Integer numToInsert, Boolean doInsert, Map nameValue) { List accounts = new List(); for( Integer i = 0; i < numToInsert; i++ ) { Account a = new Account( Name='Test Account'+String.valueOf(i) ); for(String key : nameValue.keySet()){ a.put(key, nameValue.get(key)); } accounts.add(a); } if( doInsert ) { insert accounts; } return accounts; } //create contacts public static List createContacts(Integer numToInsert, Boolean doInsert, Map nameValue) { List contacts = new List(); for( Integer i = 0; i < numToInsert; i++ ) { Contact a = new Contact( LastName='Test Contact'+String.valueOf(i),Email = String.valueOf(i)+'random-wedsasdascsdfusvs@gmail.com'); for(String key : nameValue.keySet()){ a.put(key, nameValue.get(key)); } contacts.add(a); } if( doInsert ) { insert contacts; } return contacts; } public static List createLeads(Integer Size) { List leadList = new List(); for(Integer i=0;i createELOQUAMA(List leadList) { List maList = new List(); for(lead l:leadList){ ELOQUA__Marketing_Activity__c ma = new ELOQUA__Marketing_Activity__c(); ma.ELOQUA__Lead__c = l.Id; maList.add(ma); } insert maList; return maList; } } Erik Peterson | Application Support Analyst Tuff Shed, Inc. | IT Department Phone: 303-474-5684 Email: epeterson2@tuffshed.com From: Erik Peterson Sent: Wednesday, September 28, 2016 7:59 AM To: 'reply' Subject: RE: (Salesforce Developers): New reply to your question.

Hello Peter, 

Just add this line before "system.runas()"
User thisUser = [SELECT Id FROM User WHERE Id = :UserInfo.getUserId()];

and replace this line  "System.runAs(u)​"
 
system.runAs(thisUser)

Hope this will help you. 

Thanks
karthik
