Depends on the level, I would say, and JUST what you are trying to test (and/or teach). In any case discussing this with a professor, he suggested that the burden be put on the student. Rather than supply them with, allow them to bring, for example, a card with anything written on it. He felt that students would do a little more focused thinking in preparation.
Have tried both letting them bring almost anything but their book and just a sheet. It perhaps helps as a psychological crutch, but not much in solving problems. On a personal level when I used to work as an 'applied' mathematican I definitely depended on my knowledge of where to find hints to solve problems rather than absolute knowlege. There is just too much to know.
Another point. If I do supply 'aids', then I raise the level of 'difficulty'.
