Test Class For Controller

Hi All,

How to write test class for below class.

public with sharing class ContactSearchController {

  // the soql without the order and limit
  private String soql {get;set;}
  // the collection of contacts to display
  public List<Contact> contacts {get;set;}

  // the current sort direction. defaults to asc
  public String sortDir {
    get  { if (sortDir == null) {  sortDir = 'asc'; } return sortDir;  }

  // the current field to sort by. defaults to last name
  public String sortField {
    get  { if (sortField == null) {sortField = 'lastName'; } return sortField;  }

  // format the soql for display on the visualforce page
  public String debugSoql {
    get { return soql + ' order by ' + sortField + ' ' + sortDir + ' limit 20'; }

  // init the controller and display some sample data when the page loads
  public ContactSearchController() {
    soql = 'select id,firstname, lastname,, interested_technologies__c,Test__c from contact where != null ';
// != null 
  // toggles the sorting of query from asc<-->desc
  public void toggleSort() {
    // simply toggle the direction
    sortDir = sortDir.equals('asc') ? 'desc' : 'asc';
    // run the query again

  // runs the actual query
  public void runQuery() {

    try {
      contacts = Database.query(soql + ' order by ' + sortField + ' ' + sortDir + ' limit 20');
    } catch (Exception e) {
      ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR, 'Ooops!'));


  // runs the search with parameters passed via Javascript
  public PageReference runSearch() {

    String firstName = Apexpages.currentPage().getParameters().get('firstname');
    String lastName = Apexpages.currentPage().getParameters().get('lastname');
    String accountName = Apexpages.currentPage().getParameters().get('accountName');
    String technology = Apexpages.currentPage().getParameters().get('technology');
    String Test= Apexpages.currentPage().getParameters().get('Test');

    soql = 'select id,firstname, lastname,,interested_technologies__c,Test__c from contact where != null';
if (!firstName.equals(''))
soql += ' and firstname LIKE \''+String.escapeSingleQuotes(firstName)+'%\'';
if (!lastName.equals(''))
soql += ' and lastname LIKE \''+String.escapeSingleQuotes(lastName)+'%\'';
if (!accountName.equals(''))
soql += ' and LIKE \''+String.escapeSingleQuotes(accountName)+'%\''; 
if (!accountName.equals(''))
soql += ' and Test__c  LIKE \''+String.escapeSingleQuotes(Test)+'%\''; 
if (!technology.equals(''))
soql += ' and interested_technologies__c includes (\''+technology+'\')';
    // run the query again

    return null;

  // use apex describe to build the picklist values
  public List<String> technologies {
    get {
      if (technologies == null) {

        technologies = new List<String>();
        Schema.DescribeFieldResult field = Contact.interested_technologies__c.getDescribe();

        for (Schema.PicklistEntry f : field.getPicklistValues())

      return technologies;          


Since writing a test class to cover all of the facets of this class is not something that anyone on here will do for you, I can give you some pointers and hopefully get you started.  I would recommend that you do some reading on testing [1] [2] [3] [4] to get a better understanding.  Each of your individual tests should only tests one specific portion of you class (ie a constructor test, sendEmail test, contactSelected test, etc).  You should also have both a postitive (everything works perfectly) and a negative (things are not right) test.

Each test should follow the following structure:
  • Setup of test data. This includes creation of any data needed by your class.  Account, Contacts etc
  • Starting the test. This is calling Test.startTest() to reset the governor limits
  • Calling your class / method
  • Stopping the test.This is calling Test.stopTest() to reset the governor limits and allow for any async jobs to finish
  • Asserting that your changes have worked
    • If you have inserted/updated/deleted data, you need to query for the updates
    • Run System.assert, System.assertEquals, System.assertNotEquals to verify that you got the correct data back

If you have any specific problems with your tests, feel free to create a new post with the part of the class you are trying to test and your current test method, and you will more likely get a better response then asking for someone to essentially write an entire test class for you.
