title: GTest change output of failure
body: <p>I have written a Parameterized Gtest using a struct I made as the parameter value. When the test fails it writes a byte object of the struct like so:</p>
  
  <pre><code>[  FAILED  ] RulesNoProcessing/StressTest.MainTest/2, where GetParam() = 
               40-byte object &lt;01-12 00-00 02-00 00-00 F4-01 00-00 ...&gt;.
  </code></pre>
  
  <p>Is there anyway way that I can customize the output? I know that there is predicate formats for assertions but I need to do something similar with the actual outcome of the test. If anyone can I help I would really appreciate it!</p>
