All our tests subclass TestCase with our own, which includes the
method

  def assert_flequal(exp, actual, msg='')
    if exp == 0.0
      error = 1e-7
    else
      error = exp.abs/1e7
    end

    assert((exp - actual).abs < error, 
           "#{msg} Expected #{'%f' % exp} got #{'%f' % actual}")
  end

Latest versions report the count of asserts executed.
