title: How to debug my Eunit test suite run when using rebar3?
body: <p>I have created an <code>release</code> app with rebar3 (beta-4).
  Added some eunit tests and wrote some code.</p>
  
  <p>For now I have to debug one test case to see what I have to add to make the implementation to work properly.</p>
  
  <p>I found some articles about using <code>dbg</code> from Erlang console and I found how to write debug info from Eunit. But I need to get info from code that I have to test (the actual implementation(logic)).</p>
  
  <p>Is there a way to debug Erlang code (actual source code, not the test one) when <code>rebar3</code> is used with <code>eunit</code> argument?</p>
  
  <p>I'm using tracing in terminal like there: <a href="https://aloiroberto.wordpress.com/2009/02/23/tracing-erlang-functions/" rel="nofollow noreferrer">https://aloiroberto.wordpress.com/2009/02/23/tracing-erlang-functions/</a></p>
