How to use the @jupyterlab/codemirror/src.CodeMirrorEditorFactory function in @jupyterlab/codemirror

it('should create a new editor', () => {
      const factory = new CodeMirrorEditorFactory();
      const editor = factory.newDocumentEditor({ host, model });
      expect(editor).to.be.an.instanceof(CodeMirrorEditor);
      editor.dispose();
    });

it('should create a new editor with given options', () => {
      const factory = new CodeMirrorEditorFactory(options);
      const editor = factory.newDocumentEditor({
        host,
        model
      }) as CodeMirrorEditor;
      expect(editor).to.be.an.instanceof(CodeMirrorEditor);
      for (let key in Object.keys(options)) {
        const option = key as keyof CodeMirrorEditor.IConfig;
        expect(editor.getOption(option)).to.equal(options[option]);
      }
      editor.dispose();
    });
