Test

@isTest(seeAllData=true) 
public class attachPDFTestClass {

static testMethod void testAttachments() { 
    Facturatie__c a = new Facturatie__c(Facturatie__c.Accountname__r.Name='Test');
    insert a; 

    Attachment attach=new Attachment(); 
    attach.Name='Unit Test Attachment'; 
    Blob bodyBlob=Blob.valueOf('Unit Test Attachment Body'); 
    attach.body=bodyBlob; attach.parentId=a.id;
    insert attach;

    List<Attachment> attachments=[select id, name from Attachment where parent.id=:a.id]; 
    System.assertEquals(1, attachments.size()); 

    Test.StartTest();
    FeedItem f = new FeedItem();
        f.ParentId = a.id;
        f.body = 'test';
        insert f;
        FeedComment fc = new FeedComment();
        fc.CommentBody = 'legal test';
        fc.FeedItemId = f.Id;
        insert fc;
        Test.StopTest();
        System.assertEquals ('legal test', fc.commentbody); 
    }
}

I get the error:

Invalid field initializer

    @isTest(seeAllData=true) <- makes the world sad. Why aren't you creating your test data? – Girbot Feb 15 '17 at 16:00
  • In the testclass line 5 Facturatie__c a = new Facturatie.... – Eager 2 Learn apex Feb 15 '17 at 16:01

You cannot set the value of a relationship field like you are doing here:

Facturatie__c a = new Facturatie__c(Facturatie__c.Accountname__r.Name='Test');

Not to mention the format of

Facturatie__c.Accountname__r.Name='Test'

Is not valid, no need to include the Object Name as part of the field name.

You should be setting the Id value to the field

Facturatie__c a = new Facturatie__c(Accountname__c = [YOURVALIDID]);

You will need to create the AccountName__c object first obviously.
