      For option 1, the test integrands have the form:
      <ol>
        <li>
          f1(x) = cos(2*omega*x);
        </li>
        <li>
          f2(x) = 1
        </li>
        <li>
          f3(x) = exp(x*x) * exp(-px)/(1+exp(-qx));
        </li>
        <li>
          f4(x) = exp(x*x) * sin ( x^2 );
        </li>
