title: How to execute tests that match a regular expression only?
body: <p>In sbt 0.10.1, I frequently use <code>test-only</code> to narrow down the number of my tests.</p>
  
  <pre><code>sbt&gt; test-only com.example.MySpec
  </code></pre>
  
  <p>However, I want to narrow down such that I only run tests whose name/description matches a regular expression. Is there some syntax to achieve something like this?</p>
  
  <pre><code>sbt&gt; test-only .*someRexExp.*
  </code></pre>
