Hi, can someone help me write the  test method for the following custom component. I couldnt find any link to custom component test methods in the force.com knowledgebase/community. Please help.


public with sharing class AutoComplete_Controller{

    public AutoComplete_Controller() {}
    public AutoComplete_Controller(ApexPages.StandardController controller) {}

	private List<String> resultsname = new List<String>();
	private Boolean hasparams = false;
	private Boolean hasnoresults = false;
    public String state = '';
    //Getters and Setters
 	public Boolean getHasparams(){
 		return hasparams;
 	public void clearValues(){
 		hasparams = false;
 	public Boolean getHasnoresults(){
 		return hasnoresults;	

	public void avoidRefresh(){

 	/*public void setState(String sName) {
        state = sName;
        system.debug('sName  - ' + sName);
    public String getState() {
        return state;
    public PageReference searchSuggestions() {

		//Initalize variables, hasparams just indicates that a search has started
        hasparams = true;
        hasnoresults = false;

		//Obtain current parameters
        String sobjectname = System.currentPageReference().getParameters().get('objectname');
        String stext = String.escapeSingleQuotes(System.currentPageReference().getParameters().get('aname').trim())+'%';
        String stateText = String.escapeSingleQuotes(System.currentPageReference().getParameters().get('statename').trim());
        system.debug('State Name  - ' + state);
        system.debug('stateText - ' + stateText);
        //Limit Suggestions to 10 Results
        Integer iLimit = 10;
     //Validate if there's an input and get results
     if(stext.length() > 2){

			  //String sql = 'select City__C from ' + sobjectname + ' where City__C like \''+stext+'\' and State__c = ' + stateText + '' limit '+ iLimit;
			  String sql = 'select City__C from ' + sobjectname + ' where City__C like \'' + stext + '\' and State__c = \''+ stateText+'\' GROUP BY City__C'; 
			  // limit ' + iLimit;
			  //lstAR = [];
			  system.debug('SQL Formed + ' + sql );
		         	for(sobject x : Database.query(sql)){
		        		String s  = String.escapeSingleQuotes(((String)(x.get('City__C'))));
		}catch(Exception e){
			resultsname.add('Unexpected Error, please contact support- ');	

       return null;
	 public List<String> getResultsname(){
	  	  //Make sure to clear past values
			hasnoresults = true;
			resultsname.add('No Results');
	      return resultsname;

I think the reason you're having difficulty finding any links to help you out here is because you're searching for the wrong thing.


This is a controller extension, not a custom component.


Here's a good place to start:




But I am using this controller in the component , and here is the code for the component


<apex:component controller="AutoComplete_Controller">

<apex:attribute name="InputId" description="Id of the InputField to which the AutoComplete Componente will belong, use {!$Componente.THEID}" type="String" required="true"/>
<apex:attribute name="AutoCompleteId" description="Unique Id for this AutoComplete Component" type="String" required="true" />
<apex:attribute name="ObjectName" description="This is the lookup Object." type="String" required="true"/>
<apex:attribute name="ClassName" description="This is the name of the CSS Class used to style the AutoComplete Menu." type="String" required="true"/>
<apex:attribute name="Width" description="AutoComplete Width, In case you need to adjust it for certain inputs" type="Integer" required="true"/>
<apex:attribute name="StateName" description="State Name" type="String" required="true" />
          <apex:actionFunction name="search{!AutoCompleteId}" action="{!searchSuggestions}" rerender="OP_" immediate="true" >
             <apex:param name="aname" value="" />
             <apex:param name="objectname" value="" />
             <apex:param name="statename" value="" />
           <apex:actionFunction name="clear{!AutoCompleteId}" action="{!clearValues}" rerender="OP_" immediate="true"/>
           <div id="suggestions"><div id="{!AutoCompleteId}" class="{!ClassName}" style="position:absolute;display:none;width:{!Width}px !important;"></div></div>
           new AutoComplete(document.getElementById('{!InputId}'),document.getElementById('{!AutoCompleteId}'),'search{!AutoCompleteId}','clear{!AutoCompleteId}','{!ObjectName}', document.getElementById('{!StateName}'));
           <apex:outputPanel id="OP_{!AutoCompleteId}" layout="block">
            var container = document.getElementById('{!AutoCompleteId}');
                container.innerHTML = '';
            var myElement;
            var textNode;
            var aIds;   
            <apex:actionStatus ><apex:facet name="stop">     
                <apex:repeat value="{!resultsname}" var="a" rendered="{!hasparams}">
                        myElement = document.createElement('div');
                            myElement.id = '{!AutoCompleteId}N_R';
                            myElement.style.background = "#CCCCFF";
                            textNode = document.createTextNode('{!a}');                   
                            textNode = document.createTextNode('{!a}');
              if(document.getElementById('{!InputId}').type == 'hidden'){
                var cont=document.getElementById('{!AutoCompleteId}');cont.innerHTML='';cont.style.display='none';
