### Question:
BasePlugin implements Plugin { @Override public void initialize(RequestContext requestContext) { this.context = requestContext; this.configuration = configurationFactory. initConfiguration(context.getConfig(), context.getServerName(), context.getUser(), context.getAdditionalConfigProps()); this.initialized = true; } BasePlugin();   BasePlugin(ConfigurationFactory configurationFactory); @Override void initialize(RequestContext requestContext); final boolean isInitialized();  }### Answer:
@Test public void testInitialize() { ConfigurationFactory mockConfigurationFactory = mock(ConfigurationFactory.class); Configuration configuration = new Configuration(); RequestContext context = new RequestContext(); when(mockConfigurationFactory. initConfiguration(context.getConfig(), context.getServerName(), context.getUser(), context.getAdditionalConfigProps())) .thenReturn(configuration); BasePlugin basePlugin = new BasePlugin(mockConfigurationFactory); basePlugin.initialize(context); assertTrue(basePlugin.isInitialized()); assertEquals(configuration, basePlugin.configuration); assertEquals(context, basePlugin.context); }
