Hanna Bergsma Help Writing Test Coverage on Simple Trigger!
I am not a coder and am looking to write test coverage for this simple trigger:
trigger ConDoc on ContentVersion (after insert) {
List<ContentVersion> conver = [SELECT Id, Title, OwnerId FROM ContentVersion WHERE Id IN: Trigger.newMap.keySet()];
for (ContentVersion CV: conver){
CV.OwnerId= '005F0000002QTR2IAO';
CV.Title = 'HannaTest';
}
update conver;
}
Right now this is where I am at, I have no idea what I am doing. I appreciate any help. Im getting an Insert Failed when I run the Test
@isTest public class Test_ConDocTrigger {
static testMethod void TestData(){
ContentVersion CV = new ContentVersion();
CV.OwnerId = '005F0000002QTR2IAO';
CV.Title ='Test Name';
insert CV;
}
}
Providing sample test classes for contentversion here
@isTest private class ContentDocumentTest { private static testMethod void testCreate() { ContentVersion contentVersion_1 = new ContentVersion( Title = 'Penguins', PathOnClient = 'Penguins.jpg', VersionData = Blob.valueOf('Test Content') IsMajorVersion = true ); insert contentVersion_1; ContentVersion contentVersion_2 = [SELECT Id, Title, ContentDocumentId FROM ContentVersion WHERE Id = :contentVersion_1.Id LIMIT 1]; List<ContentDocument> documents = [SELECT Id, Title, LatestPublishedVersionId FROM ContentDocument]; System.assertEquals(documents.size(), 1); System.assertEquals(documents[0].Id, contentVersion_2.ContentDocumentId); System.assertEquals(documents[0].LatestPublishedVersionId, contentVersion_2.Id); System.assertEquals(documents[0].Title, contentVersion_2.Title); } }Let me know if it gives you any coverage
When running this the methods fail and i get
"Error MessageSystem.DmlException: Insert failed. First exception on row 0; first error: INVALID_ARGUMENT_TYPE, The argument is null or invalid.: []
Stack TraceClass.Test_ConDocTrigger.testCreate: line 10, column 1"
