TypeError: _ is not a function while writing jest unit test case in react

Question

我有一个 function 如下图

export const getTopL1L2Errors = (data) => {
    const dataByPriority = [];
    data.forEach((record, counter) => {
        if (record['New Lv1-Lv2'] !== '#N/A') {
            dataByPriority.push(record);
        }
    });
    const result = _(dataByPriority)
        .countBy('New Lv1-Lv2')
        .map((count, l2CaseName) => ({ l2CaseName, count }))
        .value();
    const sortedL2List = _.orderBy(result, ['count'], ['desc']);
    const top10List = sortedL2List.slice(0, 10);
    return top10List ;
};

我在 countBy 中使用 loadash，orderBy 逻辑工作得很好，但是当我开玩笑地运行测试用例时

TypeError: _ is not a function

  62 |         }
  63 |     });
> 64 |     const result = _(dataByPriority)
     |                    ^
  65 |         .countBy('New Lv1-Lv2')
  66 |         .map((count, l2CaseName) => ({ l2CaseName, count }))
  67 |         .value();

即使我已经在文件 import * as _ from 'lodash' 中导入了 loadash；

新的编写测试用例不确定什么是工作请帮我解决这个问题
