title: Can I hide angular build progress output when running tests from karma?
body: <p>I am configuring a build process for an Angular 4 application and would like to silence progress output as it muddies the runner's logs.</p>
  
  <p>The project configs were generated using angular cli (v1.0.1)</p>
  
  <p>Using <code>ng build</code>, it is possible to pass a <code>--no-progress</code> flag to silence the build/compilation progress output.</p>
  
  <p>Is it possible to configure karma in a way to silence progress output for the build it performs before tests are run?</p>
