title: Completely removing tests from angular4
body: <p>I have built a really small application using <code>angular4</code>. I have the main app component, two subcomponents and one service. I feel like I don't need tests for such a small application and want to remove everything test related to make the project cleaner</p>
  <p>So my question is what are all the files I can remove from my project that are related to testing? I already deleted the spec files under my components but what next? Can I delete the <code>src/test.ts</code>, <code>src/tsconfig.spec.js</code>, <code>protractor.conf.js</code>, <code>karma.conf.js</code> and etc? Do I have to modify some configurations if I deleted this?</p>
  <p>Also on a side note does angular cli allow to create a new project without all this test related stuff?</p>
