title: Using minitest to test that hash contains array values of specific size
body: <p>How would one test that the returned value from a method contains a hash with values that are arrays of elements of no less than 3 and no greater than 5?</p>
  
  <p>Here is the hash:</p>
  
  <pre><code>{455=&gt;[638205575, 298486374, 51848956, 113629430], 310=&gt;[457008489, 587967610, 241469500, 991788158], 430=&gt;[1047793131, 510532105, 1018350795, 281110143, 980190962]}
  </code></pre>
  
  <p>I would show my attempts at this, but they're pathetic. I'm still wrapping my head around testing.</p>
