unit-testing - 测试：由于 firebase 和 bootstrap 导致单元失败。我如何导入这些？
问题描述
我尝试编辑 vue.config.js 但未能解决问题：
这是我的package.json：
{
"name": "tp-health-test",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint",
"test:unit": "vue-cli-service test:unit"
},
"dependencies": {
"axios": "^0.18.0",
"bootstrap": "^4.3.1",
"bootstrap-vue": "^2.0.0-rc.19",
"chart.js": "^2.8.0",
"firebase": "^5.11",
"register-service-worker": "^1.6.2",
"vue": "^2.6.10",
"vue-chartjs": "^3.4.2",
"vue-class-component": "^7.1.0",
"vue-property-decorator": "^8.1.1",
"vue-router": "^3.0.6",
"vue-slider-component": "^3.0.31",
"vuefire": "^2.0.0-alpha.24",
"vuejs-datepicker": "^1.5.4",
"vuex": "^3.1.1",
"vuex-map-fields": "^1.3.4"
},
"devDependencies": {
"@types/chai": "^4.1.0",
"@types/mocha": "^5.2.4",
"@vue/cli-plugin-pwa": "^3.7.0",
"@vue/cli-plugin-typescript": "^3.7.0",
"@vue/cli-plugin-unit-mocha": "^3.7.0",
"@vue/cli-service": "^3.7.0",
"@vue/test-utils": "1.0.0-beta.29",
"chai": "^4.1.2",
"typescript": "^3.4.5",
"vue-template-compiler": "^2.6.10"
}
}
终端输出：
警告：这是一个以浏览器为目标的 Firebase 包，但它似乎是在 Node 环境中运行的。如果在 Node 环境中运行，请确保您使用的"main"是package.json.
如果您使用的是 Webpack，您可以指定"main"为第一项
"resolve.mainFields"：
https ://webpack.js.org/configuration/resolve/#resolvemainfields
如果使用 Rollup，请使用rollup-plugin-node-resolve插件并设置"module"
为 false 和"main"true：
