Ich bin neu in der Jest-Testsuite für Vue JS und integriere sie in meine Nuxt JS-Anwendung. Ich habe einige grundlegende Tests eingerichtet, um zu überprüfen, ob es sich bei der Komponente um eine Vue-Instanz handelt, und diese Tests werden erfolgreich bestanden.
Ich versuche jetzt, ein Element auf meiner Seite zu finden und zu prüfen, ob es existiert und welchen Inhalt es enthalten könnte.
Das ist meine Struktur

Der von mir eingerichtete Test liefert Folgendes:
import { mount } from '@vue/test-utils'
import LoanTerm from '@/components/Form/Steps/Loan/LoanTerm'
describe('LoanTerm', () => {
test('is a Vue instance', () => {
const wrapper = mount(LoanTerm)
expect(wrapper.vm).toBeTruthy()
})
test('terms are available for selection', async () => {
const wrapper = mount(LoanTerm)
const terms = await wrapper.find('.jest__datasets-terms')
expect(terms.exists()).toBe(true)
})
})
Die Ergebnisse, die ich bei der Durchführung dieses Tests erhalten habe, waren meine „Begriffe zur Auswahl“. „Der Test ist fehlgeschlagen, weil ein Fehler.
eingegangen istIch habe es auch mit findAll versucht und es gibt nichts zurück
Was habe ich verpasst?

看起来 modal 的内容（包括您的测试正在寻找的“datasets-terms”按钮）最初并未呈现，因为 termSelectionModalIsOpen 被初始化为 false，并且没有任何设置将其设置为 true。该模式可能看起来与此类似：
// Modal.vue
使用 data() 属性挂载 LoanTerm，该属性将 termSelectionModalIsOpen 初始化为 true，以便呈现模式的内容：
const wrapper = mount(LoanTerm, {
data () {
return {
termSelectionModalIsOpen: true,
}
},
})
我注意到 LoanTerm.vue 中缺少 jest__datasets-terms 类，但我认为这只是一个复制粘贴错误。
