Entities like Open Zeppelin offer "well tested and audited" (I'm paraphrasing) open source Solidity code for common patterns such as ownership, ERC20 tokens, etc.
Are there any such entities (or just normal developers) who are, in the same vein as Open Zeppelin, open sourcing rigorous tests for code that is supposed to comply with the popular ERC standards?
Specifically, I've written some ERC721 compliant code, and I'm wondering if there are really good truffle test modules for this code. Would probably be more rigorous than what I'd write, and would definitely save me a lot of time and effort.
