writing test methods

I can't for the life of me grasp the concept of test methods. 

 

I have a very basic class that deactivates specific users but i don't know how to write a test method for it.

 

 

global class deactivateAccount {    
	webservice static String deactivateUserAccount(){
        String myResult; // define the result that will be returned
        Integer countUsers = 0; // count the updated users
        List<User> myUsers = [
                        SELECT u.Profile.Name, u.isActive
                        FROM User u
                        WHERE u.Profile.Name = 'test' and u.IsActive = TRUE
			];
        for (User aUser: myUsers){
            aUser.IsActive = FALSE;
            countUsers++;
        }
        update myUsers;
        return 'done: '  + countUsers;
    }
}
 
 How do I test this? Can someone EXPLAIN what i'd be testing.
 
Thank you!

it is my idea here， but i did not run it and i like to konw the result from your thanks:
 
public static testMethod void testdeactivateUserAccount()

    { 
      deactivateUserAccount();
      Profile p = [select id from profile where name='test' limit 1];

    User testuser = new User(profileid = p.Id, IsActive = TRUE, alias = 'test', email='test@hotmail.com',
             lastname='Testing', country='New Zealand', username='test@hotmail.com');
        insert testuser;
      String mes = deactivateUserAccount();
      System.assertEquals(FALSE,[select u.ISACTIVE from User u WHERE Id=:testuser.Id].IsACTIVE);
      SYstem.assertEquals('done: 1',mes);

     }

you rock! the coverage is 77%, can you explain the reasoning, the train of thoughts you had writing the test method? I'm trying to understand the concept.


NZ_XueNZ_Xue
i like to see those code that have not been tested, could you list them? thanks


SergiuSergiu
it all checked to 100% ... I had to change the profile name from test to the actual profile name I have in my org and then it jumped to 100% coverage. And I think I get the idea of testing as well:
1. prepare dummy data
2a. if you test a trigger then do the action that would trip the trigger.
2b. if you test a method/function then call that function
3. write system.assert  to write to the log file
 
4? check results returned by function/trigger

My mistake, I should remind you to get profile name from your sandbox.  I doubted about the 77%coverage, 
 
 :smileyvery-happy:  100%  is acceptable one. few suggestions :
 
1 100% is not necessary.
2 you do not have to hard code the profile name if your konw how to use SystemRunAs(user) .(teststart(), teststop()...)
3 focus on user cases not coding lines coverage.

Hello,
 
Could you make a suggestion on how to test the following:
 
 
global class MassLogNoAnswer {
  WebService static Integer insertTasks(Id[] iParentIds) {
    Task[] tasks = new Task[0];
    for (Id iParentId : iParentIds) {
        Tasks.add(new Task(WhoId = iParentId,
                           Type = 'No Answer',
                           Status = 'Completed'));
    }
    insert tasks; //Bulk Insert 
     
    return tasks.size();
  }
}

Dear NZ_Xue,
 
I have very similar class structure and web service, but instead of SOQL, it has a SOSL query. 
This web service is called from a custom button on VF page, everyhting works good, but when I call the web service from a test class, SOSL retuns nothing .. any reason as to why this may be happnening?  
global class ProductAdminWebService { 
    
    //This method is called from custom 'Go Live' button on Product Administration page
    webservice static string goLive(string recordId, string status, string productRegion){   
        
        Product_Administration__c pa;
        //Stores Products and its related Services returned by SOSL
        List<List<SObject>> searchList;
        
        system.debug('recordId: ' + recordId);
        system.debug('status: ' + status);
        system.debug('productRegion: ' + productRegion);
        
        //Display an error message if record status is not approved or scheduled
        if(status != 'Approved' && status != 'Scheduled'){
            return 'The updates needs to be approved before it can go live. Please contact your system administrator for further details.';
        }
        else{
        	            
            //1. Run SOQL to get List<List<SObject>> of Product_Administration__c and all its related Service_Administration__c
            //searchList[0]: list<Product_Administration__c>
            //searchList[1]: list<Service_Administration__c>
            
            if(productRegion == 'NA'){
	            searchList = [FIND :productRegion IN ALL FIELDS
	                                              RETURNING 
	                                                 Product_Administration__c (id, Description__c, Product__c, Product_Region__c, AP_Price__c, Direct_Price__c, Dist_Price__c, LA_Price__c, Standard_Price__c, Schedule_Date__c WHERE Id= :recordId), 
	                                                 Service_Administration__c (id, Description__c, Product__c, Product_Region__c, AP_Price__c, Direct_Price__c, Dist_Price__c, LA_Price__c, Standard_Price__c WHERE Product_Administration__c= :recordId LIMIT 7)
	                                              LIMIT 8];
            }
            else if(productRegion == 'EMEA'){
	            searchList = [FIND :productRegion IN ALL FIELDS 
	                                              RETURNING 
	                                                 Product_Administration__c (id, Description__c, Product__c, Product_Region__c, DISTID__c, DISTIE__c, SID__c, SIE__c, VADD__c, VADE__c, Standard_Price__c, Schedule_Date__c WHERE Id= :recordId),

	                                              LIMIT 10];
