Functional testing for Metachain Node RPC

This folder contains a set of functional tests designed to perform functional testing on the Metachain Eth RPC.

It is written in typescript, using Mocha/Chai as Test framework.

Test flow

Tests are separated depending on their genesis requirements. Each group will start a metachain test node with a given spec before executing the tests.

Build the node for tests

cargo build --release --features rpc-binary-search-estimate

Installation

npm install

Run the tests

npm run build && npm run test

You can also add the Metachain Node logs to the output using the METACHAIN_LOG env variable. Ex:

METACHAIN_LOG="warn,rpc=trace" npm run test

(The metachain node be listening for RPC on port 19933, mostly to avoid conflict with already running metachain node)

Required env : DEFID to set binary path GENESIS_PATH to load genesis state from a genesis.json file. Defaults to repository's genesis.json

genesis.json format :
