使用Angular-CLI使用Karma和Jasmine设置进行ng测试时出现许多错误

Getting these errors on running the ng test command. I have created this project using Angular-Cli. Ng serve is working fine without any error but ng test not running properly.

    Even I changes the auto created target ES5 to ES6.

Below is my tsconfig.json

    {
    "compileOnSave": false,
    "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
