reactjs - 无法准备 bool “true”测试用例上的属性__mobxInstanceCount失败， typescript 和mobx

类型错误：无法在布尔值“true”上创建属性“mobxinstancecount”

      at Object.<anonymous> (src/Stores/DashboardStore.ts:9:14)
      at Object.<anonymous> (src/__tests__/DashboardStore.test.ts:3:24)

Test Suites: 1 failed, 1 total
mobx.js:2620 mentions about global multiple instance.

仪表板.test.ts
从“../stores/dashboardstore”导入dashboardstore；

describe('DashboardStore', () => {
    let dashboardStore;
    beforeEach(() => {
        dashboardStore = DashboardStore;
    });
    // tslint:disable-next-line:no-console
    console.log(dashboardStore);
});
 FAIL  src\__tests__\DashboardStore.test.ts
  ? Test suite failed to run

我的请求是关于如何对组件进行单元测试和存储提供一些提示。
谢谢你。

我不知道为什么，对我来说，当我试图将窗口声明为全局时，jest配置文件出现了问题。
