Hi Salesforcedevs,

I need some help creating a testclass to test my custom controller. I never wriiten one for a controler before and wouldn't know how to "Push" the save button on the VF page to run the controller.

To explain:
VF page simply displays a apex:form with fields of the Lead object. No id's are passed through URL. Page is hosted on Force.com sites, just a blanc "create a lead form":
Page Tipformulier
 

<apex:page sidebar="false" showHeader="false" controller="Tipform" standardStylesheets="false" applyBodyTag="false" applyHtmlTag="false">

<div id="wrapper">
    <div id="header">
        <img alt="Van Gansewinkel" class="auto-style1" src="{!$RESOURCE.HeaderTip800}" ></img>
    </div>
    
  <div class='scfForm'>
    <apex:form >
        <div id="tipgever">
            
            <div class="scfSectionContent">
                <div class="scfIntroBorder">
                In het onderstaande formulier kunt u de gegevens over uw tip invullen.<br />
                </div>
            <h2>Gegevens Tipgever</h2>
            <apex:outputLabel value="Voor- en achternaam *" />
            <apex:inputField value="{!lead.Naam_chauffeur__c}" required="true"/>
            <apex:outputLabel value="Regio *"/>
            <apex:inputField value="{!lead.Regio__c}" required="true"/>
            <apex:outputLabel value="E-mailadres"/>
            <apex:inputField value="{!lead.Privat_email__c}"/>
            <apex:outputLabel value="Vestiging Tipgever" />
            <apex:inputField value="{!lead.Planningslocatie_chauffeur__c}" />
            </div>
            
        </div>
        
        <div id="tip">
            
            <div class="scfSectionContent">
            <h2>Tipgegevens</h2>
            <apex:outputLabel value="Tip voor *"/>
            <apex:inputField value="{!lead.Lead_for__c}" required="true"/>
            <apex:outputLabel value="Type Tip *" />
            <apex:inputField value="{!lead.Tip_chauffeur__c}" required="true"/>
            <apex:outputLabel value="Iemand gesproken?"/>
            <apex:inputField value="{!lead.Contact_met_lead__c}"/>
            </div>
           
        </div>
        
        <div id="klant">
            
            <div class="scfSectionContent">
            <h2>Bedrijfsgegevens</h2>
            <apex:outputLabel value="Bedrijfsnaam *" />
            <apex:inputField value="{!lead.Company}" required="true"/>
            <apex:outputLabel value="Voornaam" />
            <apex:inputField value="{!lead.FirstName}" />
            <apex:outputLabel value="Achternaam *" />
            <apex:inputField value="{!lead.LastName}" />
            <apex:outputLabel value="E-mailadres" />
            <apex:inputField value="{!lead.Email}" />
            <apex:outputLabel value="Telefoon *" />
            <apex:inputField value="{!lead.Phone}" required="true"/>
            <apex:outputLabel value="Straat + huisnr *" />
            <apex:inputField value="{!lead.Street}" required="true"/>
            
            <apex:outputLabel value="Postcode" />
            <apex:inputField value="{!lead.PostalCode}"/>
           
            <apex:outputLabel value="Plaats *" />
            <apex:inputField value="{!lead.City}" onfocus="" required="true"/>
            <apex:outputLabel value="Land" />
            <apex:inputField value="{!lead.Country}"/>
            <apex:outputLabel value="Sector" />
            <apex:inputField value="{!lead.Industry}"/>
            </div>
           
        </div>
        
        <div id="bijkomend">
            
            <div class="scfSectionContent">
            <h2>Bijkomende Informatie</h2>
            <apex:outputLabel value="Omschrijving tip *"/>
            <apex:inputField value="{!lead.Omschrijving_tip__c}" required="true"/>
            <div class="scfSubmitButtonBorder">
            <apex:commandButton action="{!save}" value="Tip Indienen" />
            </div>
            </div>
            
        </div>    
        
    </apex:form>
</apex:page>

Custom Controller Tipform

public class Tipform {

// the Topform record we are adding values to
  public Lead lead {
    get {
      if (lead == null)
        lead = new Lead();
        lead.RecordTypeId ='012200000009dAI';
        lead.LeadSource = 'Tip form';
       
      return lead;
    }
    set;
  }

  public Tipform() {
    // blank constructor
  }

  // save button is clicked
  public PageReference save() {

    try {
      insert lead; // inserts the new record into the database
    } catch (DMLException e) {
      ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'Error creating new tipform.'));
      return null;
    }

    // if successfully inserted new contact, then displays the thank you page.
    return Page.bedankt;
  }

}

So when someone comes on the URL he gets a blank form with leadfields he has to fill in and then hits Save. Lead is immediately created in Salesforce and the visitor is redirected to a thank you page.

I have really no clue how to write a testclass for this. Could someone please help me?
