我一直在关注本指南和本指南,使用 webpacker 在 Rails 5.1 上使用 vue-test-utils 和 vue 2 设置玩笑测试。我能够在没有 vue 组件的情况下运行基本测试,但尝试挂载 vue 组件会导致错误:
TypeError: Cannot create property '_Ctor' on string 'PostAddress'
7 |
8 | it('mounts', () => {
> 9 | let wrapper = shallow('PostAddress');
10 |
11 | expect(1 + 1).toBe(2);
12 | });
at Function.Vue.extend (node_modules/vue/dist/vue.runtime.common.js:4785:67)
at createConstructor (node_modules/@vue/test-utils/dist/vue-test-utils.js:4562:25)
at mount (node_modules/@vue/test-utils/dist/vue-test-utils.js:4654:12)
at shallow (node_modules/@vue/test-utils/dist/vue-test-utils.js:4691:10)
at Object.<anonymous> (spec/javascript/PostAddress.spec.js:9:19)
我的测试文件PostAddress.test.js
如下所示:
import { mount } from '@vue/test-utils' // mounts with children
import { shallow } from '@vue/test-utils' // mounts without children
import PostAddress from 'packs/components/PostAddress.vue';
describe('PostAddress', () => {
it('mounts', () => {
let wrapper = shallow('PostAddress');
expect(1 + 1).toBe(2);
});
});
的相关部分package.json
:
"devDependencies": {
"@vue/test-utils": "^1.0.0-beta.12",
"babel-jest": "^23.0.0-alpha.0",
"babel-preset-es2015": "^6.24.1",
"jest": "^22.4.2",
"vue-jest": "^2.2.1",
"webpack-dev-server": "2.11.2"
},
"jest": {
"roots": [
"spec/javascript"
],
"moduleDirectories": [
"node_modules",
"app/javascript"
],
"transform": {
"^.+\\.js$": "<rootDir>/node_modules/babel-jest",
".*\\.(vue)$": "<rootDir>/node_modules/vue-jest"
},
}
该组件本身在浏览器中运行良好(并且很简单)。在我添加语句并尝试挂载/浅化组件 之前,Jest 正在处理一个简单的expect(1 + 1).toBe(2);
断言。let
还有什么我需要的吗?第一次使用很多这些工具,所以感谢任何指针!
