### Question:
STKPlugin extends PluginAdapter { @SuppressWarnings("unused") @Override public void initialize(PluginLoaderData plugindata, Toolbox toolbox) { myTransformer = new STKLayerTransformer(toolbox.getDataRegistry(), MantleToolboxUtils.getMantleToolbox(toolbox).getDataGroupController(), toolbox.getEventManager()); myAttributionTransformer = new AttributionTransformer(toolbox.getDataRegistry(), toolbox.getMapManager()); ServerToolboxUtils.getServerToolbox(toolbox).getServerSourceControllerManager() .setPreferencesTopic(STKServerSourceController.class, STKPlugin.class); new EnvoyDebuggins(toolbox); }  @Override Collection<? extends Transformer> getTransformers(); @SuppressWarnings("unused") @Override void initialize(PluginLoaderData plugindata, Toolbox toolbox);  }### Answer:
@Test public void testInitialize() { EasyMockSupport support = new EasyMockSupport(); Toolbox toolbox = createToolbox(support); PluginLoaderData loaderData = new PluginLoaderData(); support.replayAll(); STKPlugin plugin = new STKPlugin(); plugin.initialize(loaderData, toolbox); support.verifyAll(); }
