所以我有 1 个带有 3 个测试的 spec.ts 文件。测试运行良好：
HeadlessChrome 0.0.0 (Windows 7 0.0.0): Executed 3 of 3 SUCCESS (0.255
secs / 0.027 secs)
但覆盖率始终显示 0/0：
=============================== Coverage summary ===============================
Statements : 100% ( 0/0 )
Branches : 100% ( 0/0 )
Functions : 100% ( 0/0 )
Lines : 100% ( 0/0 )
================================================================================
我查看了很多示例，但我不明白它有什么问题。
这是我的karma.config.js：
module.exports = function (config) {
config.set({
basePath: ".",
frameworks: ["jasmine"],
files: [
"./wwwroot/dist/vendor.js",
"./boot-tests.js"
],
preprocessors: {
"./boot-tests.js": ["webpack", "sourcemap"],
"./ClientApp/app/**/!(spec).ts": ["coverage"]
},
coverageReporter: {
includeAllSources: true,
reporters: [
{ type: "in-memory" }
]
},
remapCoverageReporter: {
"text-summary": null,
html: "./_report/coverage/html-report"
},
reporters: [
"html",
"coverage",
"remap-coverage",
"progress"
],
htmlReporter: {
outputFile: "index.html",
outputDir: "_report/tests"
},
webpackServer: {
noInfo: true
},
webpack: require("./webpack.config.js")()
.filter(conf =>
conf.target !== "node"
),
webpackMiddleware: {
stats: "errors-only"
},
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: false,
browsers: ["ChromeHeadless"],
singleRun: true
});
};
引导测试.js：

var testing = require("@angular/core/testing");
var browser = require("@angular/platform-browser-dynamic/testing");
testing.TestBed.initTestEnvironment(
browser.BrowserDynamicTestingModule,
browser.platformBrowserDynamicTesting()
);
Object.assign(global, testing);
var appContext = require.context("./ClientApp/app", true, /\.spec\.ts/);
appContext.keys().map(appContext);
webpack.config.js：
const path = require('path');
const webpack = require('webpack');
const merge = require('webpack-merge');
const CheckerPlugin = require('awesome-typescript-loader').CheckerPlugin;
module.exports = (env) => {

const isDevBuild = !(env && env.prod);
const sharedConfig = {

output: {

},
module: {

{ test: /\.(png|jpg|jpeg|gif|svg)$/, exclude: /node_modules/, use: 'url-loader?limit=25000' }
]
},
plugins: [new CheckerPlugin()]
};
// Configuration for client-side bundle suitable for running in browsers
const clientBundleOutputDir = './wwwroot/dist';
const clientBundleConfig = merge(sharedConfig, {
entry: { 'main-client': './ClientApp/boot-client.ts' },
output: { path: path.join(__dirname, clientBundleOutputDir) },
plugins: [
new webpack.DllReferencePlugin({
context: __dirname,
manifest: require('./wwwroot/dist/vendor-manifest.json')
})
].concat(isDevBuild ? [
// Plugins that apply in development builds only
new webpack.SourceMapDevToolPlugin({
filename: '[file].map', // Remove this line if you prefer inline source maps
moduleFilenameTemplate: path.relative(clientBundleOutputDir, '[resourcePath]') // Point sourcemap entries to the original file locations on disk
})
] : [
// Plugins that apply in production builds only
new webpack.optimize.UglifyJsPlugin()
])
});
return [clientBundleConfig];
};
