title: running unit tests of schematics/scully
body: <p>After having forked <code>scully</code>, running <code>npm test</code> from the root folder launches <code>jest</code> tests but doesn't launch the unit tests with jasmine under ./schematics/scully. </p>
  
  <p>When running <code>npm test</code> from under ./schematics/scully, it doesn't work:</p>
  
  <pre class="lang-sh prettyprint-override"><code>git clone git@github.com:atao60/scully.git
