我当前正在使用:
"mocha": "^5.2.0"
"mocha-webpack": "^2.0.0-beta.0"
"webpack": "^4.19.1"
"nyc": "^13.0.1"
出于某种原因,我得到了奇怪的源文件。
.tmp/mocha-webpack/1537879911832/webpack:/src
| 61.18 | 29.63 | 64.29 | 61.18 | |
db.js
我想知道这是怎么产生的,因为排除不起作用
"nyc": {
"exclude": [
"./tmp/**/*"
],
}
这是我的webpack文件
var nodeExternals = require("webpack-node-externals")
const path = require("path")
const webpack = require("webpack")
const webpackConfig = {
mode: "none",
context: path.resolve(__dirname),
resolve: {
extensions: [".js"],
alias: {
"#": path.join(__dirname, "../src"),
}
},
output: {
// use absolute paths in sourcemaps (important for debugging via IDE)
devtoolModuleFilenameTemplate: "[absolute-resource-path]",
devtoolFallbackModuleFilenameTemplate: "[absolute-resource-path]?[hash]"
},
devtool: "inline-cheap-module-source-map",
plugins: [
new webpack.NamedModulesPlugin()
],
target: "node", // webpack should compile node compatible code
externals: [nodeExternals()], // in order to ignore all modules in node_modules folder
}
module.exports = webpackConfig
答案 0 :(得分:1)
我通过阅读以下手册来使它正常工作:https://github.com/vuejs/vue-test-utils-mocha-webpack-example
主要的技巧是安装babel-plugin-istanbul
和更新.babelrc
文件:
"env": {
"test": {
"plugins": ["istanbul"]
}
}
package.json
如下:
"nyc": {
"exclude": [
"**/tests/**/*.js",
".tmp/**/*.js",
"webpack.config.js"
]
}
webpack.config.js
如下:
var path = require('path')
var webpack = require('webpack')
const nodeExternals = require('webpack-node-externals')
module.exports = {
entry: './src/main.js',
output: {
// use absolute paths in sourcemaps (important for debugging via IDE)
devtoolModuleFilenameTemplate: '[absolute-resource-path]',
devtoolFallbackModuleFilenameTemplate: '[absolute-resource-path]?[hash]',
},
resolve: {
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': path.resolve(__dirname, 'src')
}
},
module: {
rules: [
{
test: /\.vue$/,
loader: 'vue-loader'
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
},
{
test: /\.(png|jpg|gif|svg)$/,
loader: 'file-loader',
options: {
name: '[name].[ext]?[hash]'
}
}
]
},
devServer: {
historyApiFallback: true,
noInfo: true
},
performance: {
hints: false
},
devtool: 'inline-cheap-module-source-map',
externals: ["fs", nodeExternals()],
mode: 'development',
plugins: [
new webpack.NamedModulesPlugin()
]
}
