I have the following trigger:

trigger HelloWorldTrigger on Book__c (before insert) {
    Book__c[] books = Trigger.new;
    MyHelloWorld.applyDiscount(books);
}

which calls the function in the follwoing class:

public class MyHelloWorld {
    public static void applyDiscount(Book__c[] books) {
        for (Book__c b: books) {
            b.Price__c *= 0.9;
        }
    }
}

but when I am running a test script:

@isTest
private class HelloWorldTestClass {
    static testMethod void validateHelloWorld() {
        Book__c b = new Book__c(Name='Behind the Cloud', Price__c=100);
        System.debug('Price before inserting new book: ' + b.Price__c);
        // Insert book
        insert b;
        // Retrieve the new book
        b = [SELECT Price__c FROM Book__c WHERE Id =:b.Id];
        System.debug('Price after trigger fired: ' + b.Price__c);
        // Test that the trigger correctly updated the price
        System.assertEquals(90, b.Price__c);
    }
}

its giving me a 0% code coverage


Can anyone please help me with this?

Does <apex:pageMessages /> work the same with the VF page is embedded in a standard page?

I've added (inside the form tag)...

<apex:pageMessages />

then from the controller extn - I'm doing a 

ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR, 'ERROR message.'));

But I never see the message.  I've verified that the code is executing for the ApexPages.add...

 

I am in need of some serious help here.  I am trying to add the ability to add attachments to a visualforce page before the VF page is saved.  I found the code online but I am getting the following error:  Unknown Property 'Incident_Reports__cStandardController.IncidentReport'.  I have triple checked that the extension is correct, so I'm not sure why this error keeps coming up.

Apex Class:
 

public class IncidentReportAttachment {

    private final Incident_Reports__c IncidentReport;

    public Attachment attachment {
        get {
            if (attachment == null) attachment = new Attachment();
            return attachment;
        }

        set;
    }

    public IncidentReportAttachment (ApexPages.StandardController stdController)
    {
        IncidentReport = (Incident_Reports__c)stdController.getRecord();
    }

    public PageReference save() {
        insert IncidentReport;
        attachment.parentId = IncidentReport.Id;
        insert attachment;
      
        PageReference page = ApexPages.currentPage();
        page.setRedirect(true);
        return page;
     }
}

Here is the VF page:
 

<apex:page standardController="Incident_Reports__c" extensions="IncidentReportAttachment">

I'm at a loss as to why I keep getting this error.  Any help you can provide will be greatly appreciated.

Thanks,

Is there anything like function "ListFind" in apex.

 

such that  ListFind(a,b) returns true or false depending on if  an element "b" is there in list "a" or not.

To test a visualforce page, we pass the record id to the page, as in,

 

https://c.na9.visual.force.com/apex/pages/AccountRecord?id=a00E0000002RzBR

 

I want to dynamically pass the record id so I created a class, however it's giving an error, can someone please help me correct my code.
