Vue3 使用 vitest 测试 ElementPlus 控件
我正在使用 vite 运行 Vue3,无法为使用 ElementPlus 库的组件编写任何测试。显然需要注入其他东西,但我不知道该怎么做。
我有以下 dateControl.test.js:
import { describe, expect, test } from 'vitest';
import { ref } from 'vue';
import DateCtrl from '@/components/DateCtrl.vue';
import { mount } from "@vue/test-utils";
import ElementPlus from "element-plus";
describe("DateCtrl.vue", () => {
const messages = {
"en-US" : {
strings: {
placeholder: 'a',
label: 'b'
}
}
};
const locale = "en-US";
const data = ref ({
date: ''
});
test ("Arrange DateCtrl", async () => {
const component = mount(DateCtrl, {
props: {
vModel: data.value.date,
modelValue: data.value.date,
labelLoc: "label",
className: "w1x5",
placeholderLoc: "date"
},
global: {
plugins: [ElementPlus],
mocks: {
$t: (msg) => {
const params = msg.split('.');
return messages[locale][params[0]][params[1]];
}
}
}
});
//fails on previous lines.
expect(typeof component !== "undefined", "component created").toBeTruthy();
let h3Text = component.findAll('h3')[0].element.innerHTML;
expect(component.findAll('.form').length === 1, "form element rendered").toBeTruthy();
expect(h3Text === "d", "locale strings correct").toBeTruthy();
});
});
它甚至没有达到“预期”测试,失败并显示消息:
Error: Cannot find module 'C:\source\mySite\node_modules\dayjs\plugin\customParseFormat'
imported from
C:\source\mySite\node_modules\element-plus\es\components\date-picker\src\date-picker.mjs
Did you mean to import dayjs/plugin/customParseFormat.js?
I am running Vue3 with vite and can't write any tests for components that use the ElementPlus library. Something else needs to be injected apparently but I don't know how to do that.
I have the following dateControl.test.js:
import { describe, expect, test } from 'vitest';
import { ref } from 'vue';
import DateCtrl from '@/components/DateCtrl.vue';
import { mount } from "@vue/test-utils";
import ElementPlus from "element-plus";
describe("DateCtrl.vue", () => {
const messages = {
"en-US" : {
strings: {
placeholder: 'a',
label: 'b'
}
}
};
const locale = "en-US";
const data = ref ({
date: ''
});
test ("Arrange DateCtrl", async () => {
const component = mount(DateCtrl, {
props: {
vModel: data.value.date,
modelValue: data.value.date,
labelLoc: "label",
className: "w1x5",
placeholderLoc: "date"
},
global: {
plugins: [ElementPlus],
mocks: {
$t: (msg) => {
const params = msg.split('.');
return messages[locale][params[0]][params[1]];
}
}
}
});
//fails on previous lines.
expect(typeof component !== "undefined", "component created").toBeTruthy();
let h3Text = component.findAll('h3')[0].element.innerHTML;
expect(component.findAll('.form').length === 1, "form element rendered").toBeTruthy();
expect(h3Text === "d", "locale strings correct").toBeTruthy();
});
});
It doesn't even get to the "expect" tests, fails with message:
Error: Cannot find module 'C:\source\mySite\node_modules\dayjs\plugin\customParseFormat'
imported from
C:\source\mySite\node_modules\element-plus\es\components\date-picker\src\date-picker.mjs

这一点似乎表明节点希望您使用
.js
扩展名,而 element 没有这样做。我猜这是因为您可能正在运行旧的节点版本。 Element 至少需要 节点 v16。
This bit seems to indicate that node expects you to use
.js
extension and element is not doing that.I'm guessing this is because you may be running an older node version. Element requires at least node v16.
我也有这个问题。
看来这个问题已经在这个拉取请求中解决了 - https://github .com/element-plus/element-plus/pull/6811
I have this problem too.
