setting the appdir in Dancer::Test - perl

Question

I have an dancer webapp that I'm trying to test, and I have a few issues related to paths. It appears that the appdir setting isn't being set correctly.
The top of my test code is:
use MyApp;
use Dancer::Test;
if I dump out the settings (using dd from Data::Dump) from:
my $settings = Dancer::Config::settings();
dd $settings;
I get:
{ appdir => "/Library/WebServer/Documents/myapp/lib",
apphandler => "Standalone",
auto_reload => 0,
charset => "",
confdir => "/Library/WebServer/Documents/myapp/lib",
content_type => "text/html",
daemon => 0,
engines => {},
envdir => "/Library/WebServer/Documents/myapp/lib/environments",
environment => "development",
handlers => {},
logger => "file",
plugins => {},
port => 3000,
public => "/Library/WebServer/Documents/myapp/lib/public",
server => "0.0.0.0",
server_tokens => 1,
startup_info => 1,
template => "simple",
traces => 0,
views => "/Library/WebServer/Documents/myapp/lib/views",
warnings => 0}
clearly it's not setting the appdir correctly. It doesn't appear that it matters how I call code (i.e. the working directory).
I've been calling it as perl -I lib -I ../lib t/001_base.t with the additional library calls as MyApp.pm needs modules in both lib and ../lib.
When I run the same code as a standalone webapp which is the following in bin/app.pl which has the code:
use Dancer;
use MyApp;
dance;
dumping the settings gives me the right appdir, which loads the configuration file and sets all of the other correctly.
In my test code, I thought that adding the lines:
Dancer::set appdir=>"/Library/WebServer/Documents/myapp"
Dancer::Config->load;
would do it. However that sets the appdir correctly, but doesn't change any other parameters. From the Dancer::Test code, there is an import command which appears to do what I want, but didn't help at all. Any other thoughts?
