Functional testing for Substrate Frontier Node RPC

This folder contains a set of functional tests designed to perform functional testing on the Frontier 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 frontier template test node with a given spec before executing the tests.

Build the node for tests

cargo build --release

Installation

npm install

Run the tests

npm run build && npm run test

You can also add the Frontier Node logs to the output using the FRONTIER_LOG env variable. Ex:

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

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