Maybe it would not be practical, but using a dark enclosure during test is
the fastest, cheapest and easiest way of conducting this kind of test.

LEDs emmit light in certain wavelenghts, and you can get sensors and filters
to improve rejection of unwanted light, but even this does not mean that
there won't be spurious light in the same wavelenght as the LED.
