使用业力茉莉花和离子的代码覆盖率

Question

我正在使用Ionic开发应用程序。我需要做单元测试。我用业力和茉莉花。我的问题是这是我的第一个使用离子的应用程序。我已经使用Angular开发了一些应用程序，但从未遇到过单元测试的问题。

当我运行此命令（位于site上）时：

karma start ./test-config/karma.conf.js --coverage

在执行单元测试（生成html报告程序等）时，我的报告是空的（我的意思是每个文件为0％）

这是我的karma.conf.js

var webpackConfig = require('./webpack.test.js');
const path = require('path');

module.exports = function (config) {
