Development Cycle

In order to keep the ccip-develop branch in working condition, we need to make sure the integration test written in the CCIP repo will pass.

As such, part of CI will run this integration test combined with your latest pushed change.

Follow the steps below to ensure that we don't run into any unexpected breakages.

1. Create a PR on chainlink-ccip with the changes you want to make.
2. CI will run the integration test in the CCIP repo after applying your changes.
3. If the integration test fails, make sure to fix it first before merging your changes into the ccip-develop branch of chainlink-ccip. You can do this by:
   • Creating a branch in the CCIP repo and running go get github.com/smartcontractkit/chainlink-ccip@<your-branch-commit-sha>.
   • Fixing the build/tests.
4. Once your ccip PR is approved, merge it.
5. Go back to your chainlink-ccip PR and re-run the integration test workflow.
6. Once the integration test passes, merge your chainlink-ccip PR into ccip-develop, however do not delete the branch on the remote.
7. Create a new PR in ccip that points to the newly merged commit in the ccip-develop tree and merge that.
