How to run this code?

Prerequisities

• Docker engine
• Node.js version 20

1. Clone neutron, gaia and neutron-query-relayer

Clone neutron and relayer to the parent directory:

git clone [email protected]:neutron-org/neutron.git
git clone [email protected]:neutron-org/neutron-query-relayer.git

We use the Gaia network as a host network, so you need to clone it next to the neutron repos. We use v13.0.0 for the tests.

git clone [email protected]:cosmos/gaia.git
git checkout v19.0.0

2. Prepare docker environment

For the first run it's required to run make build-all in the setup/ directory to build all the docker images before you run the tests with yarn test

3. Install dependencies with command

yarn

4. Download or build contracts

Downloading

The pre-build contracts for specific commits are stored in the publicly available Google Cloud Bucket. One can download them via following commands:

node download_artifacts.js neutron-dao neutron-dev-contracts
node download_artifacts.js neutron-tge-contracts -b main

If you want to specify any specific branch/commit, use the following command to get more info on how to do that:

node download_artifacts.js --help

Building

If the contracts version you need is unavailable, or you need a custom one, you can easily use the contracts built by yourself. To do so, build the contracts from neutron-dev-contracts and neutron-dao by following respective instructions. After artifacts build, put all built .wasm files to contracts/ directory.

5. Run the tests (make sure docker daemon is running)

yarn test # all tests
yarn test:simple # basic tests
yarn test:interchaintx # interchain txs test
yarn test:interchain_tx_query # interchain tx query test
yarn test:interchain_kv_query # interchain kv query test

NOTE: To speed up tests you can run the cosmopark by youself with make start-cosmopark in the setup dir. To run test with the already running cosmopark use NO_DOCKER env variable.

NO_DOCKER=1 yarn test # all tests
...

Development

If you're developing integration tests and need to add additional helper methods to the @neutron-org/neutronjs packages, start by cloning the package repository. Use the command git clone [email protected]:neutron-org/neutronjs.git. After cloning, you have two options: either alter the package reference in the package.json file to point to your cloned repository, or use yarn link.

Once the JavaScript helper code in your local repository is ready, your next step is to create a Pull Request (PR). This PR must be reviewed and approved before it can be merged into the main branch.

However, even after the merge, you cannot immediately use the new package version in your integration tests. First, you need to wait until the updated version of the package will be published to the npmjs repository. After the new version has been published, you can incorporate it into your integration tests. This will allow you to complete the testing sequence in your GitHub Actions workflow.

Warning

Since docker-compose doesn't rebuild images on file changing, there is a chance for one to launch the tests with an outdated version of code if one changed something. To rebuild the images from scratch, do the following:

cd ../neutron
docker rmi neutron-node
docker rmi neutron-org/neutron-query-relayer
docker-compose build

Environment variables you can redefine

CONTRACTS_PATH - path to contracts that are used in the tests
NODE1_URL - REST url to the Neutron node
NODE2_URL - REST url to the Gaia node
NODE1_RPC - RPC endpoint to Neutron node
NODE2_RPC - RPC endpoint to Gaia node
ICQ_WEB_HOST - interchain query relayer web endpoint
START_BLOCK_HEIGHT - how many blocks we wait before start first test
NO_DOCKER - do not start cosmopark for tests
NO_PRINT_VERSIONS - do not print contract versions in console
DEBUG_SUBMIT_TX - log submitted txs to stdout
