The project contains code of GraphGrail data labelling escrow smart contract and its test suite.
Smart contract is written in Solidity v. 0.4.17. JavaScript helpers and a test suite use Truffle v. 4.1.3.
To run tests and backend server geth v. 1.8.2 or later is required. It also should work with latest Parity.
Repository contains smart contract code and utils for build and deployment, tests written with Truffle, data and scripts for running local geth in development mode for testing purposes, and JavaScript code for interaction with smart contract.
truffle is a folder with Truffle development environment. Escrow smart contract code resides in truffle/contracts/GGProject.sol, truffle/migrations folder contains code for smart contract deployment, truffle/test is where all the tests are.
local-dev-net is the folder with scripts and seed data required for running local geth in development mode.
ethereum-bridge folder contains JavaScript code of client and server for interacting with GraphGrail escrow and token smart contracts: ethereum-bridge/client contains code of frontend library, and ethereum-bridge/server contains implementation of Node.js backend server providing REST API. Some code is shared between frontend, backend and smart contract tests; it resides in ethereum-bridge/shared subdirectory.
Prior to developing or running tests, you need to install dependencies:
cd <project-root>
./install-deps.sh
Frontend library is built with webpack. To start development server, run npm start command in ethereum-bridge/client folder. To build production version of the library, run npm run build in the same folder and check up ethereum-bridge/client/build folder for results.
GraphGrail escrow smart contract has a test suite. To run it against TestRPC virtual blockchain just run npm test:
cd ./truffle
npm test
To run test suite against real Ethereum node, furst run local geth in dev mode:
cd ./local-dev-net
./run-geth.sh
This will set up local testing Ethereum network and populate it with seed accounts and balances specified in blockchain dump ./local-dev-net/blockchain.tar.gz. After having successfully running geth node, run npm test-local:
cd ./truffle
npm run test-local
