/**
 * Starts and clears the NGINX proxy between tests.
 *
 * You can define constants in your phpunit.xml to control how this test behaves.
 *
 * Note that the WEB_SERVER_HOSTNAME must also match with what you have in your
 * NGINX configuration file.
 *
 * To define constants in the phpunit file, use this syntax:
 * <php>
 *     <const name="NGINX_FILE" value="./tests/FOS/HttpCache/Tests/Functional/Fixtures/nginx/fos.conf" />
 * </php>
 *
 * NGINX_FILE          NGINX configuration file (required if not passed to setUp)
 * NGINX_BINARY        Executable for NGINX. This can also be the full path
 *                     to the file if the binary is not automatically found
 *                     (default nginx)
 * NGINX_PORT          Port NGINX listens to (default 8088)
 * NGINX_CACHE_PATH    directory to use for cache
 *                     Must match `proxy_cache_path` directive in
 *                     your configuration file.
 *                     (default sys_get_temp_dir() + '/foshttpcache-nginx')
 * WEB_SERVER_HOSTNAME hostname where your application can be reached (required)
