### Question:
OSGIPlugin implements PluginInterface, ClassLoadingPluginInterface { @Override public <T> T loadClass( Class<T> pluginClass ) { if ( classFactoryMap.containsKey( pluginClass ) ) { return classFactoryMap.get( pluginClass ).create( pluginClass ); } return null; } OSGIPlugin(); @Override String getCategory(); void setCategory( String category ); @Override Map<Class<?>, String> getClassMap(); @Override String getDescription(); void setDescription( String description ); @Override String getErrorHelpFile(); void setErrorHelpFile( String errorHelpFile ); @Override String[] getIds(); String getID(); void setID( String ID ); @Override String getImageFile(); void setImageFile( String imageFile ); @Override List<String> getLibraries(); @Override Class<?> getMainType(); void setMainType( Class<Object> mainType ); @Override String getName(); void setName( String name ); @Override URL getPluginDirectory(); @Override Class<? extends PluginTypeInterface> getPluginType(); @Override boolean isNativePlugin(); @Override boolean isSeparateClassLoaderNeeded(); @Override boolean matches( String id ); void setPluginTypeInterface( Class<PluginTypeInterface> pluginTypeInterface ); @Override T loadClass( Class<T> pluginClass ); BeanFactory getBeanFactory(); void setBeanFactory( BeanFactory beanFactory ); @Override ClassLoader getClassLoader(); @Override String getCasesUrl(); @Override void setCasesUrl( String casesUrl ); @Override String getDocumentationUrl(); @Override void setDocumentationUrl( String documentationUrl ); @Override String getForumUrl(); @Override void setForumUrl( String forumUrl ); @Override String getClassLoaderGroup(); @Override void setClassLoaderGroup( String arg0 ); @Override void setSuggestion( String suggestion ); @Override String getSuggestion(); void setClassToBeanMap( Map<Class, String> classToBeanMap ); void addClassFactory( Class<?> aClass, BlueprintBeanFactory blueprintBeanFactory );  }### Answer:
@Test public void testLoadClassNotInBeanMap() throws KettlePluginException { ArrayList result = osgiPlugin.loadClass( ArrayList.class ); assertNull( result ); }
