stephen mallette commented on TINKERPOP3-867:
---------------------------------------------
not a big deal. i had thought that IO created directories but maybe it
doesn't. I kinda don't think IO should do too much in that area now that I
think about it. But TinkerGraph should just "save" when it closes without
hassles about creating directories. So yeah, if you could just copy/paste that
code there, i think we'd be good. sound good?
> TinkerGraphProvider does not initialize temp dir

> Key: TINKERPOP3-867
> URL: https://issues.apache.org/jira/browse/TINKERPOP3-867
> Project: TinkerPop 3
> Issue Type: Bug
> Components: tinkergraph
> Affects Versions: 3.0.1-incubating
> Reporter: Matt Frantz
> Assignee: Matt Frantz
> Priority: Minor
> Fix For: 3.1.0-incubating, 3.0.2-incubating
>
>
> Running the {{GraphTest}} suite by itself fails because the temporary
> directory used to test {{TinkerGraph}} persistence is not initialized by
> {{TinkerGraphProvider}}. When run with other tests, the failure does not
> occur, presumably because another test creates the directory.
