### Question:
SpaceLet extends QBeanSupport implements Space { public void initService() throws ConfigurationException { Element config = getPersist (); grabSpace (config.getChild ("space")); initSpace (config.getChild ("init")); String name = getName(); if ("spacelet".equals (name)) name = "default"; uri = "spacelet:" + name; Element e = config.getChild ("out"); outScript = getScript (e); if (e != null) outSource = e.getAttributeValue ("source"); e = config.getChild ("push"); pushScript = getScript (e); if (e != null) pushSource = e.getAttributeValue ("source"); e = config.getChild ("in"); inScript = getScript (e); if (e != null) inSource = e.getAttributeValue ("source"); e = config.getChild ("rd"); rdScript = getScript (e); if (e != null) rdSource = e.getAttributeValue ("source"); e = config.getChild ("put"); putScript = getScript (e); if (e != null) putSource = e.getAttributeValue ("source"); }  void initService(); void startService(); void stopService(); void out(Object key, Object value); void out(Object key, Object value, long timeout); void push(Object key, Object value); void push(Object key, Object value, long timeout); void put(Object key, Object value); void put(Object key, Object value, long timeout); Object in(Object key); Object rd(Object key); Object in(Object key, long timeout); Object rd(Object key, long timeout); Object inp(Object key); Object rdp(Object key); boolean existAny(Object[] keys); boolean existAny(Object[] keys, long timeout); void nrd(Object key); Object nrd(Object key, long timeout);  }### Answer:
@Test public void testInitServiceThrowsNullPointerException() throws Throwable { SpaceLet spaceLet = new SpaceLet(); try { spaceLet.initService(); fail("Expected NullPointerException to be thrown"); } catch (NullPointerException ex) { } }
