### Question:
WXAttr implements Map<String, Object>,Cloneable { public String getLoadMoreRetry() { Object src = get(Constants.Name.LOADMORERETRY); if (src == null) { return null; } return src.toString(); } WXAttr();  WXAttr(@NonNull Map<String,Object> standardMap);  WXAttr(@NonNull Map<String,Object> standardMap, int extra); static String getPrefix(Map<String, Object> attr); static String getSuffix(Map<String, Object> attr); static String getValue(Map<String, Object> attr); WXImageQuality getImageQuality(); WXImageSharpen getImageSharpen(); String getImageSrc(); boolean canRecycled(); boolean showIndicators(); boolean autoPlay(); String getScope(); String getLoadMoreRetry(); String getLoadMoreOffset(); String optString(String key); boolean getIsRecycleImage(); String getScrollDirection(); int getOrientation(); float getElevation(int viewPortW); float getColumnWidth(); int getColumnCount(); float getColumnGap(); int getLayoutType(); @Override boolean equals(Object o); @Override int hashCode(); @Override void clear(); @Override boolean containsKey(Object key); @Override boolean containsValue(Object value); @NonNull @Override Set<Entry<String, Object>> entrySet(); @Override Object get(Object key); @Override boolean isEmpty(); @NonNull @Override Set<String> keySet(); @Override Object put(String key, Object value); @Override void putAll(Map<? extends String, ?> map); @Override Object remove(Object key); @Override int size(); @NonNull @Override Collection<Object> values(); ArrayMap<String, Object> getBindingAttrs(); WXStatement getStatement(); void setBindingAttrs(ArrayMap<String, Object> mBindingAttrs); void setStatement(WXStatement mStatement); void parseStatements(); void skipFilterPutAll(Map<String,Object> attrs); @UiThread void mergeAttr(); @Override WXAttr clone();  }### Answer:
@Test public void testGetLoadMoreRetry() throws Exception { assertEquals(null,attr.getLoadMoreRetry()); }
