reactjs - 无法在 bool 值 'true' 测试用例上准备属性 __mobxInstanceCount 失败 typescript 和 mobx

Question

TypeError:无法在 bool 值“true”上创建属性“__mobxInstanceCount”

      at Object.<anonymous> (node_modules/mobx/lib/mobx.js:2620:38)
      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.

Dashboard.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

我的要求是提供一些关于如何对组件和存储进行单元测试的提示。谢谢你。

我不知道为什么，当我试图将窗口声明为全局窗口时，对我来说这是 jest 配置文件中的一个问题。
