This repository has a collection of tools to make it easier to manage environments with SNS projects and other dependencies. If this sounds vague it's because it's a bit of a kitchen sink. Some of them are described below.
The official documentation for SNS testing has moved here.
A snapshot is an archive (.tar.xz) containing local replica state.
A stock snapshot can be created with
./bin/dfx-snapshot-stock-make
Snapshots can be shared between Linux machines but Macs can only use snapshots created on the same machine (it seems).
Default pinned versions of the used canisters are defined in
bin/versions.bash. If you want the latest versions on the canisters from the
IC repo, you can run
./bin/dfx-snapshot-stock-make --ic_commit latest --ic_dir $YOUR_IC_REPO_PATH
The IC repo directory is needed to find the latest usable commit. You can also
specify a specific commit instead of latest and then you don't need to specify
--ic_dir.
If you want to customize what is included in the snapshot, you can modify
bin/dfx-stock-deploy.
The SNSes that are being deployed are configure with sns_init.yaml as well as
the parameters passed to ic-admin from bin/dfx-sns-sale-propose.
A new stock snapshot can be released by running the Create a snapshot image workflow and checking the "Make release" box.
This will cause GitHub actions to create a new snapshot, which can be found here.
Please see the GitHub workflow that tests SNS creation on Linux and Mac.
