Did you mean for this to be webexposed/stable instead of stable/webexposed?  I'm
not sure what the naming convention is for virtual tests.

[Dirk Pranke, 2013/08/21 21:53:05]

This should be "virtual/stable/webexposed". The  convention is "virtual" +
name-of-suite + name-of-dir, as per the previous lines.

lgtm w/ this fixed.

Sounds good, will be fixed. Thanks for review!
