Getting sources

Upstream Thermostat source releases can be downloaded from: http://icedtea.wildebeest.org/download/thermostat/

Building standalone Integration Tests

This only works for releases > 0.15.

$ wget http://icedtea.wildebeest.org/download/thermostat/thermostat-<VERSION>.tar.gz
$ tar -xzf thermostat-<VERSION>.tar.gz
$ cd thermostat-<VERSION>
$ mvn clean package

The last step should produce a jar with stand-alone integration tests, which can be run against packaged thermostat. Passing integration tests will ensure that basic thermostat functionality is working.
