我有一个项目，我使用webpack进行开发/测试，并将业力作为我的测试运行员。这个项目的源文件写入js的一半，ts / tsx的一半。测试套件完全用js编写。我目前使用karma-coverage，它显示我所有js源文件的覆盖率报告，但它不支持typescript文件。我的所有测试都运行，没有问题，我只想覆盖所有测试文件的报告。谁能指出我正确的方向？
如果这有帮助，这是我的karma.conf.js。
'use strict';
const webpackCfg = require('./webpack.config')('test');
module.exports = function karmaConfig(config) {
config.set({
browsers: ['Chrome'],
files: [
'test/loadtests.js'
],

captureTimeout: 60000,

'sinon'

}
});
};

经过几天的灵魂和谷歌搜索数百个浏览器标签后，我找到了一个有效的解决方案。这是使用TypeScript 2.x和Webpack 2.x. test.js是我的切入点。它可以很容易test.ts（最终会是）。在该入口点，我加载了*.spec.js和*.spec.ts个文件。然后这些文件导入他们需要测试的任何来源。我已将所有webpack配置放在karma.conf.js中，因此更容易看到：
let myArgs = require('yargs').argv;
let path = require('path');
let webpack = require('webpack');
module.exports = function(config) {
const REPORTS_PATH = myArgs.reportsPath ? myArgs.reportsPath :path.join(__dirname, 'build');
config.set({
basePath: '',
frameworks: ['jasmine', 'es6-shim'],
files: [
'./test.js'
],
exclude: [],
reporters: ['progress', 'spec', 'coverage', 'junit', 'coverage-istanbul'],
preprocessors: {
'./test.js': ['webpack', 'sourcemap']
},
webpackServer: {
noInfo: true // prevent console spamming when running in Karma!
},
webpack: {
devtool: 'inline-source-map',
resolve: {
modules: [
path.resolve('./node_modules'),
path.resolve('./')
],
extensions: ['.js', '.ts', '.css', '.scss']
},
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
"window.jQuery": "jquery"
})
],
module: {
rules: [
{
enforce: 'pre',
test: /\.js$/,
use: 'source-map-loader',
exclude: [/node_modules/]
},
{
test: /\.ts$/,
use: [{
loader: 'awesome-typescript-loader',
options: {
module: 'commonjs'
},
}]
},
{
test: /\.js$/,
use: [{
loader: 'awesome-typescript-loader',
options: {
entryFileIsJs: true,
transpileOnly: true
}
}],
exclude: [/node_modules/],
},
{
enforce: 'post',
test: /\.(js|ts)$/,
use: [{
loader: 'istanbul-instrumenter-loader',
options: {
esModules: true
}
}],
exclude: [/node_modules/, /\.spec\.(js|ts)$/, /test/]
},
{ test: /\.html/, use: 'raw-loader' },
{ test: /\.(s)?css$/, use: 'null-loader' },
{ test: /\.(png|jpg|jpeg|gif|svg|pdf)$/, use: 'null-loader' },
{ test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/, use: 'null-loader' },
{ test: /\.(ttf|eot)(\?v=[0-9]\.[0-9]\.[0-9])?$/, use: 'null-loader' },
{ test: /\.json$/, use: 'null-loader' }
]
}
},
coverageReporter: {
type: 'in-memory'
},
coverageIstanbulReporter: {
//TODO: Figure out why the 'html' reporter blows up with istanbul-reports (something with absolute path copying files)
reports: ['text-summary', 'cobertura'],
// base output directory
dir: REPORTS_PATH,
fixWebpackSourcePaths: true,
'report-config': {
cobertura: {
file: 'coverage.xml'
},
'text-summary': {
file: null
}
}
},
junitReporter: {
outputDir: `${REPORTS_PATH}/junit/`,
outputFile: 'jasmine-results.xml'
},
// Hide webpack build information from output
webpackMiddleware: {
stats: {
chunkModules: false,
colors: true
},
noInfo: 'errors-only'
},
colors: true,
logLevel: config.LOG_ERROR,
autoWatch: true,
browsers: ['Chrome'],
singleRun: false,
autoWatchBatchDelay: 400
});
};
因此，此处的关键部分为awesome-typescript-loader，karma-coverage-istanbul-reporter，source-map-loader，而在tsconfig.json中，您希望在compilerOptions中设置这些： / p>
"inlineSourceMap": true,
"sourceMap": false,
我指出了一个关于HTML报告的TODO。它可以工作，但我无法将它输出到一个自定义目录（subdir）与TypeScript文件作为其一部分。 JavaScript只能正常工作。可能是istanbul-reports的特定于Windows的问题。如果您将html添加到reports下的coverageIstanbulReporter数组中，您应该在项目目录中看到它，但可能会在将其放入REPORTS_PATH时遇到问题。
同样值得注意的是，我使用karma-remap-coverage而不是karma-coverage-istanbul-reporter获得了很多运气，但前者无法正确生成cobertura报告，因为我需要Jenkins进行覆盖。
