title: jUnit testing Double.toString in multiple cultures
body: <p>I have an open source library which has plenty of unit tests that compare string forms of numbers.</p>
  
  <p>These tests pass fine in <code>en-GB</code>, <code>en-US</code> and other cultures where numbers are generally written in the form <code>1,234.00</code>.</p>
  
  <p>However in cultures such as Germany and France, these values are formatted differently, and the tests fail.</p>
  
  <p>How can the jUnit tests be forced to run as <code>en-GB</code>?</p>
