Make sure that the attrs option of responses_test actually work properly.

Refer to the discussion at #633.

Edit: Could also look at ContriteTFT

👍

FYI, for when this is looked at ba1cce5 was failing on the expected response (the C versus the D) so it's not just the attr that aren't working in that case.

Wrong hash, I meant 27a065e

The reason for the failures are because the order of random draws is not the same in the two cases since the opponent is Random(). The test function actually calls the strategy functions (to try to set the proper internal variables) and then overwrites with the intended (not necessarily actual history). So in this case random.random() is called one additional time (in the beginning), which mucks up the random seeding.

As far I as I can tell the test function is working as intended.
