### Question:
DefaultExtendedRenderingConfiguration implements ExtendedRenderingConfiguration { @Override public Syntax getDefaultContentSyntax() { return this.coreConfiguration.getDefaultDocumentSyntax(); }  @Override int getImageWidthLimit(); @Override int getImageHeightLimit(); @Override boolean isImageDimensionsIncludedInImageURL(); @Override List<Syntax> getDisabledSyntaxes(); @Override List<Syntax> getConfiguredSyntaxes(); @Override Syntax getDefaultContentSyntax(); List<Syntax> getAvailableParserSyntaxes();  }### Answer:
@Test void getDefaultContentSyntax() throws Exception { CoreConfiguration coreConfiguration = componentManager.getInstance(CoreConfiguration.class); when(coreConfiguration.getDefaultDocumentSyntax()).thenReturn(Syntax.XWIKI_2_1); assertEquals(Syntax.XWIKI_2_1, this.defaultExtendedRenderingConfiguration.getDefaultContentSyntax()); }
