我正在开发一个客户端应用程序,但在创建正确的 Karma 配置时遇到问题。现在,我的设置如下:
Webpack:使用 ts-loader,编译 TypeScript、资产等。
Karma:使用 webpack 插件,加载 Webpack 配置(使用 ts-loader),然后使用 Jasmine + PhantomJS 运行所有单元测试
单元测试都运行良好,但我还没有找到处理 webpack istanbul 重新映射的方法。 Karma-webpacks 似乎不会生成源映射以允许重新映射发生。任何指示将不胜感激!
业力配置:
var webpackConfig = require("./webpack.config.js");
delete webpackConfig.entry;
module.exports = function (config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jasmine'],
// list of files / patterns to load in the browser
files: [
// Non-automatically bundled libraries

'app/client/js/lib/tweenjs.min.js',

'app/client/html/**/*.html',

},
ngHtml2JsPreprocessor: {
cacheIdFromPath: function (filepath) {
// Remaps the path for Karma webpack
return '/_karma_webpack_//' + filepath.replace(/^.*[\\\/]/, '');
},
