I don't think that is right.

There were 6 tests, and only one failed.  The error is the one that
fails (test #3) :)

The problem is:
# Column name not loaded on DBICTest::DefaultJoin=HASH(0xa7d804)
trying to resolve relationship at lib/DBIx/Class/Schema.pm line 968

The core issue is quite simple.  This is because a single insert
doesn't fetch the column info from default values.

Assuming Foo has a column 'name' with a default_value.

my $obj = $schema->resultset('Foo')->create({ bar => 'baz' });
$obj->name; # undef

If something has default values, you have to do a discard_changes to
get all the data.  I thought it was only in relationships, but it
isn't.
