### Question:
Environment { public static void mock() { Environment.from("../rc-drivecontrol/src/test/resources/dukes/dukes.ini"); } private  Environment();  Environment(String propFilePath); static String readFirstLine(File file); static String osRelease(); boolean isPi(); static Environment getInstance(); boolean runningOnRaspberryPi(); Properties getProperties(); JsonObject asJsonObject(); static void from(JsonObject configJo); List<String> getMyIpAddresses(); String getString(String key); int getInteger(String key); double getDouble(String key); static void reset(); static void from(String propFilePath); static void mock(); static String dukesHome; public String propFilePath; }### Answer:
@Test public void testMock() throws Exception { Environment.mock(); JsonObject jo = Environment.getInstance().asJsonObject(); String json = jo.toString(); if (debug) System.out.println(json); Environment env = Config.getEnvironment(); assertEquals(-20.0,env.getDouble(Config.WHEEL_MAX_LEFT_ANGLE),0.001); }
