I used the post: Test class for contentdocumentlink as a model, however, when I attempt to define my own ContentSize for the ContentVersion document I receive:

Field is not writable: ContentVersion.ContentSize

ContentVersion contentVersion = new ContentVersion(
      Title = 'Penguins',
      PathOnClient = 'Penguins.jpg',
      VersionData = Blob.valueOf('Test Content'),
      IsMajorVersion = true,
      ContentSize = 304088000
    );
    insert contentVersion;

In my trigger I'm making decisions predicated on the ContentSize of the file added - if I'm unable to define ContentSize, my code coverage is only 41%

Since the field is not writable I think you only have three options.

  • If the file you are comparing to is small, you can simply create a file of that size. In your case the file size requirement seems too big to do that. That leaves you with two other solutions.
  • You can use Test.isRunningTest() to determine if it is a test and test your logic.
  • Alternatively, you could use @isTest(SeeAllData=true) and use a real file to test your logic with.

Ended up going with Kasper's third bullet point and using:

@isTest(SeeAllData=true) private class Test_ContentDocumentLink { static testMethod void myUnitTest() {
// uses a testUtility class to pre-define required fields etc. Opportunity opp = TestUtils.CreateOpportunities(1)[0]; insert opp; // not preferred, but defining ContentSize while creating a ContentVersion record resulted in the error "field not writable"
// a file larger than 304087040 bytes must reside in the org - otherwise nothing will be returned in the query List<ContentDocument> documents = [SELECT Id, Title, LatestPublishedVersionId FROM ContentDocument WHERE ContentSize > 304087040 LIMIT 1]; for (ContentDocument contentDocument: documents){ //create ContentDocumentLink record ContentDocumentLink cdl = New ContentDocumentLink(); cdl.LinkedEntityId = opp.id; cdl.ContentDocumentId = contentDocument.Id; cdl.shareType = 'V'; insert cdl; } } }
