title: how to specify a vault password file to molecule test?
body: <p>When running tests with molecule:</p>
  
  <pre><code>molecule tests
  </code></pre>
  
  <p>and some files are protected with <a href="https://docs.ansible.com/ansible/latest/user_guide/vault.html" rel="noreferrer">ansible vault</a>, the <strong>--vault-password-file</strong> must be specified to provide the password to decrypt their content.</p>
  
  <p>Although it is possible to do that with converge</p>
  
  <pre><code> molecule converge -- --vault-password-file ~/.vault.txt
  </code></pre>
  
  <p>it fails with molecule tests</p>
  
  <pre><code> $ molecule test -- --vault-password-file ~/.vault.txt
   Usage: molecule test [OPTIONS]
   Error: Got unexpected extra arguments (--vault-password-file ~/.vault.txt)
  </code></pre>
