commit 2d467544feadeefa9a484142c433170c66d32786 Author: Nick Mathewson nickm@torproject.org Date: Tue May 14 19:51:16 2019 -0400

Use new RNG and tinytest code to simplify prob_distr tests

Since the reproducible RNG dumps its own seed, we don't need to do it for it. Since tinytest can tell us if the test failed, we don't need our own test_failed booleans. --- src/test/test_prob_distr.c | 29 ++++++++++------------------- 1 file changed, 10 insertions(+), 19 deletions(-)
