From 235ed7ecb92527ce0029c2a6f5ace06707db9b28 Mon Sep 17 00:00:00 2001 From: Felix Lange Date: Fri, 17 Apr 2015 16:30:15 +0200 Subject: [PATCH] cmd/geth, tests: enable running multiple tests from a single file This commit also changes the block test loading so tests containing invalid RLP blocks can be loaded and return an error only when they are run.
