How do I get code coverage in Salesforce?

Question

I'm not a developer but found some info on GitHub which gave an Apex class that creates a Quote PDF upon creating the Quote. I tested in my sandbox and everything works perfectly, however it's telling me I have 0 code coverage so I can't deploy to Prod. Below are is the Apex and the Test for it. Any thoughts on what could be wrong? I followed all the steps in this article which provided the link to the code.

Apex Class

`Public class generateQuotePdfDocument{

@InvocableMethod   
public static void CreateQuote(List<Id> quoteIds)  
{ 
    createQuoteFutureMethod(quoteIds);
}

@future(callout=true)
public static void createQuoteFutureMethod (List<Id> quoteIds) {
    //Initialize the quote url
    String quoteUrl = '/quote/quoteTemplateDataViewer.apexp?';
    
    //Get the Quote Template Id from Custom Settings
    String quoteTemplateId = Label.QuoteTemplateId;
    
    //List variable to get all the Quote Documents
    List<QuoteDocument> lstQuoteDoc = new List<QuoteDocument>();
    
    if(!quoteIds.isEmpty() && quoteIds.size() > 0) {
        
        for(Id quoteId :quoteIds) {
            //Construct the quote URL to generate PDF
            quoteUrl += 'id=' + quoteId;
            quoteUrl += '&headerHeight=197&footerHeight=10';
            quoteUrl += '&summlid=' + quoteTemplateId;
            
            //call the quote url
            PageReference pageRef = new PageReference(quoteUrl);
            
            //get the quotePdf
            Blob quoteBlob;
            
            if(Test.isRunningTest()) {
                quoteBlob = Blob.valueOf('Generate Pdf');
            } else {
                quoteBlob = pageRef.getContentAsPDF();
            }
            
            //initialze the QuoteDocument to hold the quote pdf for insertion
            QuoteDocument quoteDoc = new QuoteDocument();
            quoteDoc.Document = quoteBlob;
            quoteDoc.QuoteId = quoteId;
            lstQuoteDoc.add(quoteDoc);
        }
    }
    
    if(!lstQuoteDoc.isEmpty() && lstQuoteDoc.size() > 0) {
        Database.insert(lstQuoteDoc);
    }
    
}

}`

Test Class

`@istest private class generateQuotePdfDocumentTest {

@testSetup static void setup() {

Product2 product = new Product2(); product.Name = 'Test Product '; product.ProductCode = '123'; product.IsActive = true; insert product;

PricebookEntry pbe = new PricebookEntry(); pbe.Pricebook2Id = Test.getStandardPricebookId(); pbe.Product2Id = product.Id; pbe.IsActive = true; pbe.UnitPrice = 10; insert pbe;

Opportunity op = new Opportunity(); op.Name = 'Test'; op.Type = 'Value Proposition'; op.Amount= 1200; op.CloseDate = Date.today().addDays(2); op.StageName = 'Created';

insert op;

Quote quote = new Quote(); quote.OpportunityId = op.Id; quote.Name = 'TestQuote'; quote.ExpirationDate = Date.today().addDays(5); quote.Status = 'Draft'; quote.Pricebook2Id = Test.getStandardPricebookId(); insert quote;

QuoteLineItem qli = new QuoteLineItem(); qli.QuoteId = quote.Id; qli.Quantity = 2; qli.PricebookEntryId = pbe.Id; qli.UnitPrice = 20; insert qli; }

@isTest static void generateQuotePdfTest() {

Quote quote = [SELECT Id, Status FROM Quote LIMIT 1];

quote.Status = 'Draft'; update quote; }

}`

In my attempt to deploy to production I realized my code coverage was 0. So I'm trying to learn how to correct this issue.

Answer 1

You are not calling your code in your test method.

Sorry on my phone but something like

Test.startTest;
  Generatequotepfddpcument.createquote(new list<id>{quote.id};
 Test.StopTest;

Answer 2

How are you calling this invocable method in your class "CreateQuote"? I guess the the update you are doing in your test class is not firing that invocable method hence the 0 coverage. Try making the update so that the condition matches in your test class for firing the invocable method.
