  def test(verbosity=1, xunitfile=None, exit=False):
      """
      Runs the full Blaze test suite, outputting
      the results of the tests to sys.stdout.
  
      This uses nose tests to discover which tests to
      run, and runs tests in any 'tests' subdirectory
      within the Blaze module.
  
      Parameters
      ----------
          Value 0 prints very little, 1 prints a little bit,
          and 2 prints the test names while testing.
      xunitfile : string, optional
          If provided, writes the test results to an xunit
          style xml file. This is useful for running the tests
          in a CI server such as Jenkins.
      exit : bool, optional
          If True, the function will call sys.exit with an
          error code after the tests are finished.
