Question

我为Syncfusion柱形图创建了组件，并尝试使用JEST（react-test-renderer）对我的代码进行单元测试，但出现错误。 TypeError：无法读取未定义的属性“ getRandomValues”

TypeError: Cannot read property 'getRandomValues' of undefined

  31 | describe('<Column />', () => {
  32 |     test('Column changes the class when hovered', () => {
> 33 |         const component = renderer.create(
     |                                    ^
  34 |             <Column data={data1} chartProp={chartProp1} />,
  35 |             );
  36 |             const tree = component.toJSON();
