title: Please make sure that the argument ContactRepository at index [0] is available in the RootTestModule context
body: <p>I'm trying to test a class via Nest. In this class (cf image below), the person who coded the class, create a repository via typeorm.</p>

  <p>When I try to test the &quot;createContact&quot; function I get the following error : &quot;Nest can't resolve dependencies of the ContactService (?). Please make sure that the argument ContactRepository at index [0] is available in the AuthModule context&quot;.</p>
  <p>This is my test class :</p>

  <p>Do you know how to make the test take this into account and therefore not get the error anymore?</p>
  <p>Thanks a lot!</p>
