类型错误：$（...）。telerik_ReportViewer不是一个函数 在我的 React Typescript 应用程序中使用 Jest 测试

问：

● ReportViewer › 渲染时不会崩溃

TypeError: $(...).telerik_ReportViewer is not a function

尝试使用 Jest 测试我的 ReportViewer.TSX 组件，代码如下，但获得上述错误任何相同的线索

// Initialize the Telerik Report Viewer with the props
if (this.reportViewerRef) {
  ($(this.reportViewerRef) as any).telerik_ReportViewer({
    serviceUrl: 'http://localhost/ReportWebAPI/api/reports/',
    reportSource: reportSource,
    scale: scale,
    viewMode: viewMode,
    printMode: printMode,
    sendEmail: sendEmail,
  });

}
