title: How to pass parameters to all the pester test scripts
body: <p>The <code>Invoke-Pester</code> command makes it possible to invoke a single test script with explicit parameters using the <code>-Script</code> parameter. But what if I want to pass the same parameters to all of the test scripts?
  I do not want to invoke pester in a loop, because I want it to produce a single test result file.</p>
  
  <p>So, how do we do it?</p>
