/**
* Helper method for loading test configuration from a file.
*
* The configuration can be specified by an environment variable. If the
* variable content is a file name, the configuration is loaded from the
* file. Otherwise it's assumed to be a json encoded configuration hash. If
* the environment variable is not set, the method tries to load a conf.php
* file from the same directory as the test case.
*
* @param string $env An environment variable name.
* @param string $path The path to use.
* @param array $default Some default values that are merged into the
* configuration if specified as a json hash.
*
* @return mixed The value of the configuration file's $conf variable, or
* null.
