任何人都可以帮助我为什么不执行测试。
我添加了spec文件：＆＃39; app / 1st.spec.ts＆＃39;根据angular.io测试web site。
describe('1st tests', () => {
it('true is true', () => expect(true).toBe(true));
});
业力没有问题。 结果如下：
Chrome 55.0.2883 (Windows 10 0.0.0): Executed 0 of 0 ERROR (0.002 secs / 0 secs)
我不知道为什么我的项目不起作用，但我在另一个新项目中测试并且执行了单元测试。请指教！
这是我的package.json。我也在使用Angular Universal。

// Then we find all the tests.

// And load the modules.

// Finally, start Karma to run the tests.

我遇到了同样的问题。
在karma.conf.js上试试这个：
mime: {
'text/x-typescript': ['ts','tsx'],
'text/javascript': ['js']
},

在你的karma.config中进行以下更改 -
files: [
{ pattern: './src/[path_to_your_app_folder]/*.spec.ts', watched: false }
]
preprocessors: {
'./tests/**/*.spec.js': ['angular-cli']
}
它将解决您的问题。

就我而言：
添加了：
mime: {
'text/x-typescript': ['ts', 'tsx']
},
编辑：
reporters: config.angularCli && config.angularCli.codeCoverage ?
['progress', 'karma-remap-istanbul'] :
['progress'],
现在测试工作正常。
