### Question:
Configurer { public final Xml getRoot() { return root; } Configurer(Media media); static void clearCache(); final void save(); final Xml getRoot(); final String getPath(); final Media getMedia(); final String getText(String... path); final String getTextDefault(String defaultValue, String... path); final String getString(String attribute, String... path); final String getStringDefault(String defaultValue, String attribute, String... path); final boolean getBoolean(String attribute, String... path); final boolean getBooleanDefault(boolean defaultValue, String attribute, String... path); final int getInteger(String attribute, String... path); final int getIntegerDefault(int defaultValue, String attribute, String... path); final double getDouble(String attribute, String... path); final double getDoubleDefault(double defaultValue, String attribute, String... path); final T getImplementation(Class<T> type, String... path); final T getImplementation(ClassLoader loader, Class<T> type, String... path); final T getImplementation(Class<T> type, Class<?> paramType, Object paramValue, String... path); final T getImplementation(Class<T> type,
                                         Class<?>[] paramsType,
                                         Collection<?> paramsValue,
                                         String... path); final T getImplementation(ClassLoader loader,
                                         Class<T> type,
                                         Class<?>[] paramsType,
                                         Collection<?> paramsValue,
                                         String... path); static final T getImplementation(ClassLoader loader,
                                                Class<T> type,
                                                Class<?>[] paramsType,
                                                Collection<?> paramsValue,
                                                String className); final boolean hasNode(String... path);  }### Answer:
@Test void testGetRoot() { final Xml root = configurer.getRoot(); assertNotNull(root); assertEquals("root", root.getNodeName()); }
