Angular4 Karma-Jasmine测试未运行

Question

我正在尝试设置我的Karma-Jasmine测试，并且无法解决我出错的问题。 似乎无法理解问题所在，并尝试过各种在线搜索解决方案，试图改变目标＆＃39;和＆＃39;模块＆＃39;除了其他修复，但似乎没有工作。 我没有使用Webpack。

Karma.Config.js

module.exports = function(config) {
config.set({
    basePath: '',
    frameworks: ['jasmine'],

    plugins: [
         require('karma-jasmine')
        ,require('karma-chrome-launcher')
        ,require('karma-jasmine-html-reporter')
    ],
    client: {clearContext: false // leave Jasmine Spec Runner output visible 
    in browser},
    files:  [{ pattern: './test.ts', watched: false }],
    mime:   {'text/x-typescript': ['ts', 'tsx']},
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: true
   });
 };

import 'zone.js/dist/fake-async-test';
import * as testing from '@angular/core/testing';
import * as testingBrowser from '@angular/platform-browser-dynamic/testing';

// There's no typing for the `__karma__` variable. Just declare it as any
declare var __karma__: any;
declare var require: any;

// Prevent Karma from running prematurely
__karma__.loaded = function () {};

// First, initialize the Angular testing environment
testing.getTestBed().initTestEnvironment(
testingBrowser.BrowserDynamicTestingModule,
testingBrowser.platformBrowserDynamicTesting()
);

// Then we find all the tests
const context = require.context('../', true, /\.spec\.ts$/);

// And load the modules
context.keys().map(context);

// Finally, start Karma to run the tests
__karma__.start();

任何方向都将受到高度赞赏...见下面的截图

更新了test.ts

//changes
import { getTestBed } from '@angular/core/testing';
import {BrowserDynamicTestingModule,platformBrowserDynamicTesting} from

// There's no typing for the `__karma__` variable. Just declare it as any
declare var __karma__: any;
declare var require: any;

// Prevent Karma from running prematurely

getTestBed().initTestEnvironment(
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting()
);
//PREVIOUS code
