Karma webpack sourcemaps ne fonctionne pas

j'utilise Karma-Webpack pour exécuter mes 2 Spécifications angulaires.

https://github.com/webpack/karma-webpack

lorsque j'exécute des tests en utilisant Karma dans Chrome, les fichiers source de mes spécifications apparaissent lisibles dans le débogueur. Cependant, le système sous Fichiers de test (my application source) est illisible.

j'utilise le karma-sourcemap-loader et j'ai mis devtool sur 'inline-source-map' comme indiqué. Qu'est-ce qui pourrait causer ce problème?

cette construction est modelée d'après L'AngularClass angular2-webpack-starter. https://github.com/AngularClass/angular2-webpack-starter
