Test coverage of selected Apex Trigger is 0%, at least 1% test coverage is required

I'm a new developer with apex. I am the getting the error when i tried to create an apex class and trigger. Could any one can help me?

 

Apex Trigger:

 

trigger ExpenseTrigger on Expense__c (before insert, before update) {

ExpenseUtil.areExpensesAllowed(Trigger.new);

}

 

Apex Class:

 

public with sharing class ExpenseUtil {

static final Double MAX_EXPENSE_PER_DAY = 1000000.00;

public static void areExpensesAllowed(Expense__c[] expenses) {

Double totalExpenses = 0;

String createdbyId = UserInfo.getUserId();

 

/* Adds the expenses created in previous requests for today */

for(Expense__c eq:[SELECT ExpenseInRs__c FROM Expense__c

WHERE Date__c = TODAY

 AND Expense__c.createdById = :createdbyId AND ExpenseInRs__c != null]) {

totalExpenses += eq.ExpenseInRs__c;

}

/* Totals the expenses in the request */

 for (Expense__c e:expenses) {

totalExpenses += e.ExpenseInRs__c;

if(totalExpenses > MAX_EXPENSE_PER_DAY)e.addError('Expense request exceeds daily limit: ' + MAX_EXPENSE_PER_DAY);

}

}

 

static testMethod void areExpensesAllowed() {System.assert('Expense' == 'Expense');

}

}

 

 

Even tried with some comments displayed in the community but not working. Thanks in advance :smileyhappy:

Try this:

 

static testMethod void areExpensesAllowed() 
{
 	Expense__c[] expense = new Expense__c[0];
        
	

	for(integer i=0;i<10;i++)
        { 
		expense.add(new Expense__c(ExpenseInRs__c = 10.00,Date__c = syatem.today()));

	} 

	insert expense;
	
	System.assert(Expense[0].ExpenseInRs__c == 10.00);

	Expense[0].ExpenseInRs__c = 1100000.00;


	update expense;

}

Hi lvivanin,
 
Thanks for your effort. But still the problem(red X appears in my trigger object) persists.

lvivaninlvivanin
is it possible to know what exact problem/error is..?


lvivaninlvivanin
Class method cannot be declared as static when used in a trigger
.

I have a trigger and a class as displayed earlier. While compiling itself i am got the below error
 
"Description-Test coverage of selected Apex Trigger is 0%, at least 1% test coverage is required
 Resource- ExpenseTrigger.trigger 
 Path- ExpenseProject/src/triggers  
 Location- line 1 
 Type- Force.com code coverage warning
"
 
even removing static declrations the effect remains the same.

When you run the test, does it give a code coverage percent for that trigger? Is it 0 there also?


lvivaninlvivanin
I tested it creating Expense object and fields similar to your code, it works fine and has 100% code coverage:
 
trigger ExpenseTrigger on Expense__c (before insert, before update) {

ExpenseUtil.areExpensesAllowed(Trigger.new);

}
 
 
public with sharing class ExpenseUtil {

static final Double MAX_EXPENSE_PER_DAY = 1000000.00;
public static void areExpensesAllowed(Expense__c[] expenses) {

Double totalExpenses = 0;

String createdbyId = UserInfo.getUserId();

 

/* Adds the expenses created in previous requests for today */

for(Expense__c eq : [SELECT ExpenseInRs__c FROM Expense__c WHERE Date__c = TODAY   AND ExpenseInRs__c != null AND createdById = :createdbyId]) 
{

totalExpenses += eq.ExpenseInRs__c;

}

/* Totals the expenses in the request */
 for (Expense__c e:expenses) {

totalExpenses += e.ExpenseInRs__c;
if(totalExpenses > MAX_EXPENSE_PER_DAY)e.addError('Expense request exceeds daily limit: ' + MAX_EXPENSE_PER_DAY);

}

}

 
static testMethod void areExpensesAllowed() 
{
    Expense__c[] expense = new Expense__c[0];
        
    

    for(integer i=0;i<10;i++)
        { 
        expense.add(new Expense__c(ExpenseInRs__c = 10.00,Date__c = system.today()));

    } 

    insert expense;
    
    System.assert(Expense[0].ExpenseInRs__c == 10.00);

    Expense[0].ExpenseInRs__c = 1100000.00;


    update expense;

}


}
 
 hope it helps!

Hi guys, 
 
thanks for your efforts. It worked fine for me but for different set of example. For mileage object it worked fine. It is not showing any compilation error. when i used the same logic for an Expense object it shows compilation error. Still wondering. :)
 
thanks
