您正在测试Dashboard组件并尝试检查ATable（）组件渲染了传递给的槽内容它。这是错误的。 考虑到 ATable 组件，在测试 Dashboard 组件时您应该检查的是 ATable 组件是否刚刚渲染。就是这样。

// In Dashboard.spec.js
it("renders ATable component.", () => {
  const ATableStub = {
    template: '<div>ATableStub</div>' 
  }
    const wrapper = shallowMount(Dashboard, {
      stubs: {
        ATable: ATableStub
      },
      data() {
        return {
          patients: [
            {
              id: 1,
              firstName: "arpit",
              lastName: "satyal",
              email: "arpited7@gmail.com",
              contact: "12345",
              address: "ktm",
              dob: "1998-07-29",
              allergies: ["Pet allergies"],
            },
          ] as IPatientResponse[],
        };
      },
    });
wrapper.findComponent(ATableStub).exists.toBe(true);
  });
});

您应该将测试 ATable 的槽内容留给测试 ATable 组件，而不是仪表板 组件。

// In ATable.spec.js
import { shallowMount, RouterLinkStub } from '@vue/test-utils'

  it("renders proper texts.", () => {
    const wrapper = shallowMount(ATable, {
      stubs: {
        RouterLink: RouterLinkStub
      },
      scopedSlots: {
        bodyCell: `
          <template slot-scope="{ column, record }" v-if="column.key === 'firstName'">
          <router-link :to="{ name: 'PatientProfile', params: { id: record.id } }">
            <div id="test-patient">{{ record.firstName }} {{ record.lastName }}</div>
          </router-link>
        </template>`
      },
      data() {
        return {
          patients: [
            {
              id: 1,
              firstName: "arpit",
              lastName: "satyal",
              email: "arpited7@gmail.com",
              contact: "12345",
              address: "ktm",
              dob: "1998-07-29",
              allergies: ["Pet allergies"],
            },
          ] as IPatientResponse[],
        };
      },
    });
    const patientNameSelector = wrapper.find("#test-patient");
    // see if the message renders
    expect(patientNameSelector.text()).toEqual("arpit satyal");
  });
});
