EIP4337 bundler compatibility tests.

Version 0.7

For more information on the motivation and importance of having a compatibility test suite, see https://notes.ethereum.org/@yoav/unified-erc-4337-mempool

For the formal schema EIP-4337 bundler RPC API spec, see https://github.com/eth-infinitism/bundler-spec

The spec test for previous release is at releases/v0.6

Prerequisites

Python version 3.8+ PDM - python package and dependency manager version 2.2.1+

Installation

Run pdm install && pdm run update-deps

Running the tests

Running with an up and running Ethereum node and bundler

Assuming you already have an Ethereum node running, EntryPoint deployed and your bundler running and ready for requests, you can run the test suite with:

pdm test

With the following parameters:

• --url the bundler to test (defaults to http://localhost:3000)
• --entry-point (defaults to 0x0000000071727De22E5E9d8BAf0edAc6f37da032)
• --ethereum-node (defaults to http://localhost:8545)
• --launcher-script (See below)
• -k <regex>, (or any other pytest param)

Running with a launcher script

You can provide a launcher script by adding the option --launcher-script to the command line.

Your launcher script will be invoked by the shell with:

<launcher-script-file> {start|stop|restart}

where:

• start should start an Ethereum node, deploy an EntryPoint contract and start your bundler.
• stop should terminate both the Ethereum node and your bundler processes, and cleanup if necessary.
• restart should stop and start atomically.

Running using the "test executor"

See https://github.com/eth-infinitism/bundler-test-executor, for the test executor to run the test suite against all registered bundler implementations.
