This post is just a suggestion/ feature request.
0x has a neat tool called sol-trace, which helps with finding the exact line in the smart contract where a nasty bug occurred. The problem is that it’s rather cumbersome to use with truffle. Here’s how my truffle-config file looks.
The recent upgrade of the OpenZeppelin SDK is *awesome* and it would be even more awesome if it had a functionality similar to sol-trace. I know it’s a long shot, since the CLI tool doesn’t run tests now, but it’s worth keeping it in mind imo.
