我基于以下示例项目在ionic3项目中实现单元测试：https://github.com/ionic-team/ionic-unit-testing-example。
它工作正常，但我有一些问题：
我可以看到编译错误（对于jasmine），而这些错误不会阻止运行测试
karma start ./test-config/karma.conf.js
webpack: Compiled successfully.
webpack: Compiling...

即使我配置了kjhtml报告器，也无法在karma启动的浏览器中显示结果。见https://github.com/ionic-team/ionic-unit-testing-example/blob/master/test-config/karma.conf.js#L52。注意我添加了progress记者，它运行正常：
reporters: ['progress', 'kjhtml'],
感谢您的帮助！
