I am drafting up a couple of unit tests for this code.

Here is what the code looks like so far:

public class ContentController {

    public ContentController() {
        file = new ContentVersion();

    public ContentVersion file { get; set; }
    public PageReference go() {
        insert file;
        return new PageReference('**url**');

The initial unit test for testing just a file upload for this code is drafted up as such:

private class BestDoctorsTest{
    private static void testUpload(){
        ContentController controller = new ContentController();
        controller.file.Body = Blob.valueOf('populated');
        PageReference redirect = controller.go();
        system.assertEquals(1, [SELECT count() FROM ContentVersion]);

Given how Blobs work and the functionality of ContentVersions this should work fine. However, apex returns this error: enter image description here

How to I correctly obtain the body of a ContentVersion?


For ContentVersion, the property that contains the blob data is 'VersionData'. Line 6 should be changed to:

controller.file.VersionData = Blob.valueOf('populated');
