Guys I don't understand how to write tests - salesforce

I have a class in which I get the number of ids per year with a soql query on a custom object:
public static Integer numberRecords(Integer year) {
List<AggregateResult> numbersOfRecords = [
SELECT Keeper__c
FROM Month_Expense_Application__c
WHERE calendar_year(MonthDate__c) =: year
];
Set<Id> keepers = new Set<Id>();
for (AggregateResult result : numbersOfRecords) {
keepers.add((Id)result.get('Keeper__c'));
}
Integer value = keepers.size();
return value;
}
I'm trying to write a test for this method by creating an object and filling in the fields it needs, then I try to get the id with a soql request and compare:
#isTest
public class ExpenseAdminControllerTests {
#isTest
public static void numberRecordsTests() {
Month_Expense_Application__c monthExpenseTest = new Month_Expense_Application__c(
Balance__c = 12.3,
Income__c = 11,
Keeper__c = '0034x00001K7kGCAAZ',
MonthDate__c = date.newInstance(2022, 11, 21)
);
Integer year = 2022;
List<Month_Expense_Application__c> numbersOfRecords = [
SELECT Keeper__c
FROM Month_Expense_Application__c
WHERE calendar_year(MonthDate__c) =: year AND Id =: monthExpenseTest.Id
];
Set<Id> keepers = new Set<Id>();
keepers.add(numbersOfRecords[0].Keeper__c);
Integer value = keepers.size();
System.assertEquals(1, value);
}
}
But i cant tell me what am i doing wrong

I guess you just forgot to insert "monthExpenseTest" in actual database, by means that you have just created a object by using below lines as you mentioned
Month_Expense_Application__c monthExpenseTest = new Month_Expense_Application__c(
Balance__c = 12.3,
Income__c = 11,
Keeper__c = '0034x00001K7kGCAAZ',
MonthDate__c = date.newInstance(2022, 11, 21)
);
by writing above lines you just created object which is present in memory only. it is not stored in database, so that it is not fetched when you try to fetch it via SOQL Query.
Now you may want to add one more line after above code.which is given as below
insert monthExpenseTest ;
so after inserting your object is stored in database. now you can fetch it via SOQL query.
So your test class will be looks like below
#isTest
public class ExpenseAdminControllerTests {
#isTest
public static void numberRecordsTests() {
Month_Expense_Application__c monthExpenseTest = new Month_Expense_Application__c(
Balance__c = 12.3,
Income__c = 11,
Keeper__c = '0034x00001K7kGCAAZ',
MonthDate__c = date.newInstance(2022, 11, 21)
);
insert monthExpenseTest;
Integer year = 2022;
Integer keepers = ExpenseAdminController.numberRecords(year);
System.assertEquals(1, keepers);
}
}
So when you are testing ExpenseAdminController then you just need to call that method because you want to test it. in test class which is mentioned in question it not testing numberRecords() method instead of you are rewriting logic.

How to get query covered in apex test class for salesforce

I'm having a tough time trying to get all code covered in my test class for an apex class.
Apex class:
public with sharing class myclass {
**public List<CustomObject1> listvar {get;set;}**
public myclass(ApexPages.StandardController sc){
CustomObject2 var = [SELECT Id, Field1__c FROM CustomObject2 WHERE Id = :ApexPages.currentPage().getParameters().get('id')];
**listvar = [SELECT Id,Name,Field1__c,Field2__c,Field3__c,Field4__c,Field5__c,CreatedDate,CreatedById FROM CustomObject1 WHERE Field2__c = :var.Field1__c ORDER BY CreatedDate DESC];**
}
}
Test Class:
#isTest
public class myclass_Test {
static testmethod void dosomething(){
Account a = new Account();
a.Name = 'Test acct';
insert a;
CustomObject4__c v = new CustomObject4__c();
v.Field1__c = '123 ABC';
v.Name = 'test name';
v.Field2__c = True;
v.Account__c = a.Id;
insert v;
... more record creates including ones for the object being queried...
PageReference pageref = Page.myVFpage;
Test.setCurrentPageReference(pageref);
ApexPages.StandardController sc = new ApexPages.StandardController(v);
myclass myPageCon = new myclass(sc);
}
}
I've tried creating a new list for the underneath the last line in the test class and populating the list, but I cannot get 100% code coverage. I marked the lines that I'm not getting any coverage from the test class with. Any suggestions?
You should put some asserts into your test Class. Something like
System.assertEquals(5, yourListsize)
I figured out that the listvar list for CustomObject1 wasn't getting populated because an Id wasn't being passed to var for CustomObject2. In the test class I had to put the record Id using ApexPages.currentPage().getParameters().put('Id', something.id);
with the Id for the record created in the test class for that object. Thanks anyways guys :-)

How to get the code coverage required to deploy Apex Class

Please Help!!!
I have this Apex controller class that I'm trying to deploy from Salesforce Sandbox to Production but I'm not getting the code coverage required!!
the class is consuming 3 objects, one is stranded and 2 are custom and constructing a hierarchy tree view for those three objects.
//Apex Class
public class TeeView {
/* Wrapper class to contain the nodes and their children */
public class cNodes
{
Public StandardObject gparent {get;set;}
public List<CustomObject1__c> parent {get; set;}
Public List<CustomObject2__c> child {get;set;}
public cNodes(StandardObject gp, List<CustomObject1__c> p, List<CustomObject2__c> c)
{
parent = p;
gparent = gp;
child = c;
}
}
/* end of Wrapper class */
Public List<cNodes> hierarchy;
Public List<cNodes> getmainnodes()
{
hierarchy = new List<cNodes>();
List<StandardObject> tempparent = [Select Id,Name , End_Date__c, Owner.Name Account.Name from Contract ];
for (Integer i =0; i< tempparent.size() ; i++)
{
List<CustomObject1__c> tempchildren = [Select Id,Name, Owner.Name , (select Id,Name, Owner.Name from CustomObject2__r) from CustomObject1__c where Related_Field__c = :tempparent[i].Id];
List<CustomObject2__c> tempchild = [Select Id,Name Owner.Name from CustomObject2__c where Related_Field__c= :tempparent[i].Id];
hierarchy.add(new cNodes(tempparent[i],tempchildren, tempchild));
}
return hierarchy;
}
}
//Test Class
#isTest
public class treeviewTest
{
static testMethod void test1()
{
test.startTest();
Account acc = new Account(Name = 'Unit test account');
insert acc;
StandardObject c = new StandardObject(
Name = 'test',
AccountId = acc.Id,
Status = 'Draft',
StartDate = System.today());
try
{
insert c;
}
catch (Exception ex)
{
ApexPages.addMessages(ex);
}
List<StandardObject> standard = [select Id, Name from StandardObject where Name = 'test'];
system.assertequals(standard.size(), 1);
CustomObject1__c s = new CustomObject1__c(
Related_StandardObjectField__c = c.Id,
Name = 'test'
);
try
{
insert s;
}
catch (Exception ex)
{
ApexPages.addMessages(ex);
}
List<CustomObject1__c> cus1 = [select Id, Name from CustomObject1__c where Name = 'test'];
system.assertequals(cus1.size(), 1);
insert new CustomObject2__c(Related_StandardObjectField__c = c.Id, Description__c = 'test');
List<CustomObject2__c> cus2 = [select Id, Name from CustomObject2__c where Description__c = 'test'];
system.assertequals(cus2.size(), 1);
insert new CustomObject2__c(Related_CustomObject1Field__c = s.Id, Description__c = 'test');
List<Mods__c> cus3 = [select Id, Name from Mods__c where Description__c = 'test'];
system.assertequals(cus3.size(), 1);
treeView view = new treeView();
view.getmainnodes();
test.stopTest();
}
}
Oh man, where do we even start... Looks like you copy-pasted some code at random trying to get the test to work? Your code works on Contract, CustomObject1__c, CustomObject2__c. Your unit test inserts Contract, Subaward__c, Mods__c. Was this some attempt at anonymizing your code? And what's this List<StandardObject> thing, it shouldn't even compile.
I think you need help of a developer with more experience, you've cobbled something together but it doesn't follow the Salesforce best practices for code...
About the main class
Smart use of subqueries will mean
you waste less SOQL (it's bad idea to blindly select all records without any filters but whatever),
don't run into errors related to "too many SOQL statements" (the limit is 100 so since you query in a loop - your code will crash and burn the moment you have around 50 Contracts)
lead to compact code occupying less lines (easier to maintain & cover with tests).
I'd go with something like that, query Contract & first related list in one go and then the parents + children in another query. Using a Map to link them for displaying.
List<Contract> levelOneAndTwo = [SELECT Id, Name, End_Date__c, Owner.Name, Account.Name,
(SELECT Id,Name, Owner.Name FROM Subawards__r)
FROM Contract];
Map<Id, SubAward__c> levelTwoAndThree = new Map<Id, Subaward__c>([SELECT Id,
(SELECT Id,Name Owner.Name FROM Mods__r)
FROM Subaward__c WHERE Contract__c = :levelOneAndTwo];
);
This wastes only 2 queries but fetches all contracts and their related data. Then you can loop over results building your wrapper object or just feed it directly to Visualforce for displaying.
About the unit test
You don't get the coverage because you're spread too thin. One unit test methods inserts only Contracts (so your main query will hit something, give you some coverage). Then another method (in completely different context) inserts some child objects - but they don't matter. In that other method there are 0 contracts so it won't even enter your main loop. Combine it into one?
Account acc = new Account(Name = 'Unit test account');
insert acc;
Contract c = new Contract(
Name = 'test contract',
AccountId = acc.Id,
Status = 'Draft',
StartDate = System.today()
);
insert c;
Subaward__c s = new Subaward(
Contract__c = c.Id,
Name = 'test'
);
insert s;
insert new Mod__c(Subaward__c = c.Id, Description__c = 'test');
Now you have nice tree hierarchy set up, from Account all the way down. Queries in the test should hit some data.
I was finally able to get %100 code coverage for the above class by adding these lines to the test class:
treeView view = new treeView();
view.getmainnodes();
system.assert(view.hierarchy.size() > 0);

Insert CSV using Apex Batch Class Salesforce for OpportunityLineItem

I want to add a button to my opportunity header record that is called Insert Products. This will send the opportunity ID to a visualforce page which will have a select file button and an insert button that will loop through the CSV and insert the records to the related opportunity.
This is for non technical users so using Data loader is not an option.
I got this working using standard apex class however hit a limit when i load over 1,000 records (which would happen regularly).
I need to convert this to a batch process however am not sure how to do this.
Any one able to point me in the right direction? I understand a batch should have a start, execute and finish. However i am not sure where i should split the csv and where to read and load?
I found this link which i could not work out how to translate into my requirements: http://developer.financialforce.com/customizations/importing-large-csv-files-via-batch-apex/
Here is the code i have for the standard apex class which works.
public class importOppLinesController {
public List<OpportunityLineItem> oLiObj {get;set;}
public String recOppId {
get;
// *** setter is NOT being called ***
set {
recOppId = value;
System.debug('value: '+value);
}
}
public Blob csvFileBody{get;set;}
public string csvAsString{get;set;}
public String[] csvFileLines{get;set;}
public List<OpportunityLineItem> oppLine{get;set;}
public importOppLinesController(){
csvFileLines = new String[]{};
oppLine = New List<OpportunityLineItem>();
}
public void importCSVFile(){
PricebookEntry pbeId;
String unitPrice = '';
try{
csvAsString = csvFileBody.toString();
csvFileLines = csvAsString.split('\n');
for(Integer i=1;i<csvFileLines.size();i++){
OpportunityLineItem oLiObj = new OpportunityLineItem() ;
string[] csvRecordData = csvFileLines[i].split(',');
String pbeCode = csvRecordData[0];
pbeId = [SELECT Id FROM PricebookEntry WHERE ProductCode = :pbeCode AND Pricebook2Id = 'xxxx HardCodedValue xxxx'][0];
oLiObj.PricebookEntryId = pbeId.Id;
oLiObj.Quantity = Decimal.valueOf(csvRecordData[1]) ;
unitPrice = String.valueOf(csvRecordData[2]);
oLiObj.UnitPrice = Decimal.valueOf(unitPrice);
oLiObj.OpportunityId = 'recOppId';;
insert (oLiObj);
}
}
catch (Exception e)
{
ApexPages.Message errorMessage = new ApexPages.Message(ApexPages.severity.ERROR, e + ' - ' + unitPrice);
ApexPages.addMessage(errorMessage);
}
}
}
First problem that I can sense is that the insert DML statement is inside FOR-loop. Can you put the new "oLiObj" into a List that is declared before the FOR-loop starts and then try inserting the list after the FOR-loop ?
It should bring some more sanity in your code.

limits using AggregateResult in batch APEX

I've just recently run into a governor limit using Batch Apex with the AggregateResult object and I was hoping someone could clearly explain this limit. I think batch APEX could support up to 50 million records, but when I use AggregateResult, I hit governor limits even though the total records in the object was about 250,000.
How does the AggregateResult limit apply within batch APEX?
Any explanation on how this limit is applied and how to overcome it would be appreciated. Should I simply avoid using AggregateResult within batch APEX? Or, if I do use it, how do I determine when this limit will be hit?
Here is a simple batch program I wrote using AggregateResult. This runs monthly and I'm aggregating Tasks related to a case by user. How can I determine if this will hit limits?
global class MemberCaseAchievementBatch implements Database.Batchable<sObject> {
public string query = 'select Id, Enhancement_Value__c from Case where RecordType.DeveloperName = \'SF_Enhancement\' AND Stage__c = \'Deployed\' AND ClosedDate = THIS_MONTH';
public Set<Id> caseIds = new Set<Id>();
public Set<Id> allCaseIds = new Set<Id>();
Integer totalCompletedCases = 0;
Integer totalAssignedCases = 0;
Double totalCompletedValue = 0;
global database.querylocator start(Database.BatchableContext BC)
{
return Database.getQueryLocator(query);
}
global void execute(Database.BatchableContext BC, Sobject[] scope)
{
for(Case c : (List<Case>)scope) {
caseIds.add(c.Id);
totalCompletedCases++;
if(c.Enhancement_Value__c == null) {
totalCompletedValue = c.Enhancement_Value__c;
}
else {
totalCompletedValue += c.Enhancement_Value__c;
}
}
for(Case c : [select Id from Case where RecordType.DeveloperName = 'SF_Enhancement' AND CreatedDate = THIS_MONTH]) {
allCaseIds.add(c.Id);
totalAssignedCases++;
}
Map<Id, Member_Goal__c> memberGoalsMap = getMemberGoals();
List<Member_Case_Achievement__c> achievementsToInsert = new List<Member_Case_Achievement__c>();
AggregateResult[] results = getMemberAchievementMetrics(caseIds);
Map<String, AggregateResult> tasksAssigned = getMemberTotalTasksAssigned(allCaseIds);
Date firstDayOfMonth = System.today().toStartOfMonth();
Date lastDayOfMonth = firstDayOfMonth.addDays(Date.daysInMonth(firstDayOfMonth.year(), firstDayOfMonth.month()) - 1);
for(AggregateResult ar : results) {
Member_Case_Achievement__c mca = new Member_Case_Achievement__c();
if(memberGoalsMap.containsKey(String.valueOf(ar.get('OwnerId')))) mca.Member_Goal__c = memberGoalsMap.get(String.valueOf(ar.get('OwnerId'))).Id;
AggregateResult aggResult = tasksAssigned.get(String.valueOf(ar.get('OwnerId')));
mca.Total_Assigned_Tasks__c = (Integer)aggResult.get('expr0');
mca.Total_Completed_Tasks__c = (Integer)ar.get('expr1');
mca.Total_Completed_Task_Value__c = (Double)ar.get('expr0');

achievementsToInsert.add(mca);
}
if(!achievementsToInsert.isEmpty() && achievementsToInsert.size() > 0) {

}
}
global void finish(Database.BatchableContext BC) {
}
private AggregateResult[] getMemberAchievementMetrics(Set<Id> caseids) {
AggregateResult[] groupedResults = [select OwnerId, SUM(Task_Value__c), Count(Id) from Task where WhatId in: caseids AND Subject in ('Requirements','Design','Develop / Config','Unit Testing') group by OwnerId];
return groupedResults;
}
private Map<String, AggregateResult> getMemberTotalTasksAssigned(Set<Id> caseids) {
Map<String, AggregateResult> aggregateResultMap = new Map<String, AggregateResult>();
for(AggregateResult ar : [select OwnerId, Count(Id) from Task where WhatId in: caseids AND Subject in ('Requirements','Design','Develop / Config','Unit Testing') group by OwnerId]) {
aggregateResultMap.put(String.valueOf(ar.get('OwnerId')), ar);
}
return aggregateResultMap;
}
private Map<Id, Member_Goal__c> getMemberGoals() {
Map<Id, Member_Goal__c> memberGoalMap = new Map<Id, Member_Goal__c>();
for(Member_Goal__c mg : [select Id, Member__c from Member_Goal__c where Goal_Period__r.Period_Start_Date__c = THIS_MONTH]) {
memberGoalMap.put(mg.Member__c, mg);
}
return memberGoalMap;
}
}
Is the limit determined by the scope? Or, is it determined by the AggregateResult query?
Batch apex allows you to run batches of up to 50 million records. So in your case you could batch over 50M Cases. Normal Apex limits still apply however inside of each batch.
You could try to limit the scope size of each batch via Database.executeBatch(yourBatch, scopeSize); where scopeSize is an Integer between 1 and 2000. Setting this to a lower number (200 is the default) would run fewer Cases per batch, in effect hopefully decreasing the size of your aggregate result too.

thanks

There is a validation rule on the Part object. To view the validation rule(s), go to Setup > Create > Objects > Part > Validation Rules.
You'll need to modify your code to create a Part__c record that complies with the validation rules.
