 *
 * To define constants in the phpunit file, use this syntax:
 * <php>
 *     <const name="VARNISH_FILE" value="./tests/Functional/Fixtures/varnish-3/fos.vcl" />
 * </php>
 *
 * VARNISH_FILE         Varnish configuration file (required if not passed to setUp)
 * VARNISH_BINARY       executable for Varnish. this can also be the full path
 *                      to the file if the binary is not automatically found
 *                      (default varnishd)
 * VARNISH_PORT         port Varnish listens on (default 6181)
 * VARNISH_MGMT_PORT    Varnish management port (default 6182)
 * VARNISH_CACHE_DIR    directory to use for cache
 *                      (default sys_get_temp_dir() + '/foshttpcache-varnish')
 * WEB_SERVER_HOSTNAME  hostname/IP your application can be reached at (required)
 *
 * If you want to test with Varnish 3, you need to define an environment
 * variable with the varnish version:
 * <php>
 *     <env name="VARNISH_VERSION" value="3" />
