Hi, 

I am fairly new to Apex development and programming in general.  My particular issue is that I am having trouble creating a test method for a custom controller.  I have a VF page with a simple form for submitting cases, and a custom controller to handle it.  I've deployed the VF page and controller to my developement org and everything works properly.  Now I want to deploy it to production but need test coverage.  

I have read through the Apex Developer's Guide and countless forum postings on developing test methods but I am still stumped.  

Below is the VF page, Custom Controller class, and my current (inadequate) test method.

VF Page: simple case submit form

<apex:page controller="SubmitCaseController"> <h1>Submit New Case</h1> <apex:form > <apex:pageMessages /> <table> <tr> <th>Your Name:</th> <td><apex:inputText value="{!c.SuppliedName}"/></td> </tr> <tr> <th>Your Email:</th> <td><apex:inputText value="{!c.SuppliedEmail}"/></td> </tr> <tr> <th>Your Account Number:</th> <td><apex:inputText required="true" value="{!acctNum}"/></td> </tr> <tr> <th>Title:</th> <td><apex:inputText required="true" value="{!c.Subject}"/></td> </tr> <tr> <th>Your Problem:</th> <td><apex:inputTextArea required="true" rows="5" value="{!c.Description}"/></td> </tr> <tr> <td><apex:commandButton value="Submit Case" action="{!submitCase}"/></td> </tr> </table> </apex:form></apex:page>

 Custom Controller: The general functionality is to use the acctnum field to match an existing account.  Then, find the appropriate contact by matching the account and email address.  Then insert the case.

public with sharing class SubmitCaseController { public Case c { get; set; } public String acctNum { get; set; } public SubmitCaseController() { c = new Case(); } public PageReference submitCase() { List<Account> accts = [SELECT Id FROM Account WHERE AccountNumber = :acctNum]; if (accts.size() != 1) { ApexPages.Message msg = new ApexPages.Message(ApexPages.Severity.FATAL, 'Invalid account number'); ApexPages.addMessage(msg); return null; } else { try { c.AccountId = accts.get(0).Id; // now look for an associated contact with the same email Contact cnt = [SELECT Id FROM Contact WHERE AccountId = :c.AccountId AND Email = :c.SuppliedEmail LIMIT 1]; if (cnt != null) c.ContactId = cnt.Id; // Specify DML options to ensure the assignment rules are executed Database.DMLOptions dmlOpts = new Database.DMLOptions(); dmlOpts.assignmentRuleHeader.useDefaultRule = true; c.setOptions(dmlOpts); // Insert the case INSERT c; return new PageReference('/thanks'); } catch (Exception e) { ApexPages.addMessages(e); return null; } } }}

 My current test method:

@isTestprivate class SubmitCaseControllerTests { public static testMethod void testSubmitCaseController() {PageReference pageRef = Page.PortalCaseSubmit; Test.setCurrentPage(pageRef); Account testaccount = new Account(name = 'Acme', AccountNumber='123456'); insert testaccount; Contact testcontact = new Contact(firstname='joe', lastname='smith', email='joe@smith.com'); insert testcontact; Case c; c.SuppliedName='Joe Smith'; c.SuppliedEmail='joe@smith.com'; c.Subject = 'Test'; c.Description = 'This is a test.'; String acctnum = '123456'; SubmitCaseController controller = new SubmitCaseController(); controller.submitcase(); Case cases = [Select ID, subject, description from Case Where account.id = :testaccount.id]; System.assertequals(cases.description, c.description); } }

My logic is to instantiate an account and contact and insert them into the database.  Then, mimic the process of someone completing the form and submitting it.  I could test both positive and negative results this way.  However, I am stumped as to how to populate the form fields and submit the form using Apex.  Any help would be appreciated.

Thanks,

Clint
