### Question:
MultipleInstanceVariableEditorPresenter extends FieldEditorPresenter<String> { static String getDisplayName(String realType) { if (getMapDataTypeNamesToDisplayNames().containsKey(realType)) { return getMapDataTypeNamesToDisplayNames().get(realType); } return realType; } @Inject  MultipleInstanceVariableEditorPresenter(final View view,
                                                   final SessionManager sessionManager); @PostConstruct void init(); @Override void setValue(String value); List<String> getSimpleDataTypes(); @Override void setReadOnly(boolean readOnly); void onVariableChange(); Path getDiagramPath(); static Map<String, String> getMapDataTypeNamesToDisplayNames();  }### Answer:
@Test public void testDisplayNameDoesNotExist() { String dataType = "java.util.List"; assertEquals(dataType, getDisplayName(dataType)); }
