A single repository intended to provide the ability to run a local Optimistic Ethereum environment including both L1 & L2 chains. This can be used to rapidly iterate over the many Optimism repositories and run integration tests.

• docker
  • At least version 19.03.12
• docker-compose
  • At least version 1.27.3
• Recommended Docker memory allocation of >=8 GB.

This package can be used to run tests, or even just spin up an easy-to-edit optimism system.

# Git clone with submodules
$ git clone [email protected]:ethereum-optimism/optimism-integration.git --recurse-submodules

$ cd optimism-integration

# The `docker` submodule is a one stop shop for building containers
$ ./docker/build.sh

# Run tests
$ make test

# Run published images of full system
$ make up

Submodules are updated automatically as commits land in master in the respective repositories through a Github action.

The submodules can be updated with:

$ git submodule update

There are two ways to run up.sh.

This is the recommended way to use this repository for building an application on the Optimistic Ethereum protocol.

Docker images are built and automatically published to Dockerhub. Docker will automaticaly use images found locally. To pull the latest images, use the command:

$ docker-compose pull

To start all of the services, run the command:

$ make up

Particular Docker images can be used by specifying an environment variable at runtime. <service_name>_TAG will be templated into the docker-compose.yml files at runtime.

To run the docker image ethereumoptimism/go-ethereum:myfeature, use the command:

$ GETH_L2_TAG=myfeature make up

This is helpful when making changes to multiple repositories and testing the changes across the whole system. See the docker repository for instructions on building custom images locally.

This is the recommended way to use this repository when developing the Optimistic Ethereum protocol itself.

The submodules can be mounted in at runtime so that any changes to the submodules can be observed in the context of the whole system. Any compiled code must be built inside of a Docker container so that it is compiled correctly. The Makefile is used for this purpose.

To build all local submodules, run the command:

$ make all

To compile only a specific service, the -s flag can be used. The possible services can be found in the docker-compose.build.yml file.

To build only go-ethereum, run the command:

$ make geth-l2

To specify using the submodules with up.sh, use the -l flag:

$ make up-local

To run all of the tests:

$ make test

This script is used to run each of the integration-tests test suites against the whole system. Each package in the integration-tests repo gets its own fresh state, meaning that the tests cannot run in parallel unless each test suite has its own instances of each of the Optimistic Ethereum services.

To run only a specific test suite:

$ make test-<test-suite>

The -p flag is used to set the PKGS environment variable and is used to specify which test suite runs. The possible test suites are found in the integration tests repository, in the packages directory.

Set PKGS to the package name to run a particular package. If PKGS is unset, each test suite will run in sequence. The name of a test suite can be found in its package.json as the .name property without the @eth-optimism prefix. Note that the name must match the name of the directory containing the test suite for the automation to work. If PKGS contains multiple packages delimated by a comma, the results will be non-deterministic and the tests should be expected to fail.

The optional directory contains additional service files that will be used if the name of the test suite has a corresponding file optional/<test-suite>-service.yml. This is useful for adding additional services that are not required for all test suites.
