Insert Contentversion - The argument is null or invalid

This is my trigger And the test class
When running the test class I get 100% coverage yet the test fails and I get the following error:

System.DmlException: Insert failed. First exception on row 0; first error: INVALID_ARGUMENT_TYPE, The argument is null or invalid.: []

Try this
public class TestNewFileAlert 
    public static testmethod void MyUnitTest()
      //  test.startTest();
        Profile p = [SELECT Id FROM Profile WHERE Name='Standard User'];
        UserRole r = [SELECT Id FROM UserRole WHERE Name='COO'];
        User futureUser = new User(firstname = 'Future', lastname = 'User',
                                   alias = 'future', defaultgroupnotificationfrequency = 'N',
                                   digestfrequency = 'N', email = 'test@test.org',

            insert cdl;
            Test.setCreatedDate(cdl.Id, DateTime.now());
          //  test.stopTest();

Hi ,

Krishnaveni A 2Krishnaveni A 2
I tried the above code, I didnt get any errors. Can u please explain in detail 
Raj VakatiRaj Vakati
You need to set the Create date in test class .. 

In your code you are refering the create date so ... 

            Test.setCreatedDate(cdl.Id, DateTime.now());

i set like above and i set ruunAs users also .. its 100% code covergae
