Welcome

This guide is intended to provide resources for those wanting to help test Metropolis EIPs. The CPP team is currently in the middle of a migration from EthDocs to a documentation site that is more dedicated to CPP-Ethereum so the documentation on creating tests for Ethereum using testeth is scattered. Everything you will need to get started should be compiled below.

Suggested skill sets needed to create and run tests

Ability to compile/build testeth and LLL compiler or run a docker file.
Ability to [understand the LLL Ethereum language](https://gist.github.com/Souptacular/fd197b1fac7c6d2660b0bef27a33ed40#lll-and-evm-st

System Design Cheatsheet

Step One: Framing The Problem a.k.a get the MVP

Identify the use cases that are in scope
Determine constraints based on scoped use cases

use case : the things your system needs to be do.

constraints : the things your system will have to consider to be able to do stuff

I think we should have all our code in a monolithic repository.

I've detailed the big benefits to having one, addressed possible issues to having one, and mentioned a few risks to not moving to a monorepo below.

Benefits To Adopting a Monolithic Repo

Golang package dependencies

Single vendor/ dir at the top level of deis/deis
All internal packages use the same external dependencies

#Translating Marty to Redux

Some people have asked how I've translated a Marty app to Redux. Once you get your head around how Redux works I found concepts in Marty translated easily. Below is side-by-side comparison of the two libraries to help you along the way.

Also if you're looking for some devtools, check out redux-devtools.
