Ich verwende Vue-Test-Utils, um eine Komponente zu testen, und habe beim Versuch, Text zu testen, diese Fehlermeldung erhalten. Auf leerem DOMWrapper kann kein Text aufgerufen werden.
Aktualisierter Code. „RangeError: Maximale Aufrufstapelgröße überschritten“ im atable.spec.ts-Test.
atable.spec.ts
import ATable from "../components/ATable.vue"; import { IPatientResponse } from "@/types/patients"; import { shallowMount, RouterLinkStub } from "@vue/test-utils"; it("renders proper texts.", () => { const wrapper = shallowMount(ATable, { props: { patients: [ { id: 1, firstName: "arpit", lastName: "satyal", email: "arpited7@gmail.com", contact: "12345", address: "ktm", dob: "1998-07-29", allergies: ["Pet allergies"], }, ] as IPatientResponse[], }, 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>`, } }); const patientNameSelector = wrapper.find("#test-patient"); // see if the message renders expect(patientNameSelector.text()).toEqual("arpit satyal"); });
Tabellenansicht Refaktorieren Sie die Tabellenkomponente in eine eigene Komponente. Es erhält nun Requisiten von der Dashboard-Komponente.

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。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。
