我目前正在尝试为使用 RCTooltip 的组件编写简单的测试:https ://github.com/react-component/tooltip

import * as Tooltip from "rc-tooltip";
console.log("qqqqqqqqqqqq: ", Tooltip);
...

<Tooltip>Hello</Tooltip>

当我在浏览器中打开应用程序时,它会打印出以下内容:

qqqqqqqqqqqq:  Module {default: ƒ, __esModule: true, Symbol(Symbol.toStringTag): "Module"}

但是,当我尝试运行此测试时:

const shallowRender = (props = {}) =>
    shallow(<Complex {...{ ...GENERIC_PROPS, ...props }} />);

describe("renders", () => {
    it("renders back and next buttons", () => {
        const wrapper = shallowRender();
        expect(1).toEqual(1);
    });
});

它打印出来:

  console.log src/shared/components/Form/Complex/index.tsx:5
    qqqqqqqqqqqq:  function Tooltip() {
        var _temp, _this, _ret;

        (0, _classCallCheck3['default'])(this, Tooltip);

        for (var _len = arguments.length, args = Array(_len), _key = 0; _key < _len; _key++) {
          args[_key] = arguments[_key];
        }

        return _ret = (_temp = (_this = (0, _possibleConstructorReturn3['default'])(this, _Component.call.apply(_Component, [this].concat(args))), _this), _this.getPopupElement = function () {
          var _this$props = _this.props,
              arrowContent = _this$props.arrowContent,
              overlay = _this$props.overlay,
              prefixCls = _this$props.prefixCls,
              id = _this$props.id;

          return [_react2['default'].createElement(
            'div',
            { className: prefixCls + '-arrow', key: 'arrow' },
            arrowContent
          ), _react2['default'].createElement(_Content2['default'], {
            key: 'content',
            trigger: _this.trigger,
            prefixCls: prefixCls,
            id: id,
            overlay: overlay
          })];
        }, _this.saveTrigger = function (node) {
          _this.trigger = node;
        }, _temp), (0, _possibleConstructorReturn3['default'])(_this, _ret);
      }

  console.error node_modules/react/cjs/react.development.js:188
    Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

为什么进口不一样??

这是我的package.json
