title: Verifying exception messages with GoogleTest
body: <p>Is it possible to verify the message thrown by an exception? Currently one can do:</p>
  
  <pre><code>ASSERT_THROW(statement, exception_type)
  </code></pre>
  
  <p>which is all fine and good but no where can I find a way to test e.what() is really what I am looking for. Is this not possible via google test?</p>
