title: Angular what can be tested in the integration test and what in the unit test
body: <p>Generating a component via Angular CLI creates a .spec file. Should integration and individual tests be included there? How can I tell if a test is individual or not.</p>
  
  <p>For example, I am testing a method that emits a value through Output, subscribing to EventEmmiter and checking the value during a subscription, is it a unit test?</p>
  
  <p>The second example.
  I'm testing the tooltip display method, which is a bootstrap component, so this is an integration test, because you need interaction with another component?</p>
  
  <p>The third example,
  I am testing a method that changes variables in the component and finally redirects to the router.navigate, check if the router has redirected to the given address - is it an integration test?</p>
  
  <p>I can not find a single answer in the documentation.</p>
