subxt

substrate-subxt is a rust substrate client built to interface with the substrate chain. It provides light client support, making it possible to work with untrusted substrate nodes.

It is unique in it's support for writing integration tests, by replacing the light client with a full node. This functionality is demonstrated in sunshine-keybase.

To see these tests in action, clone the repo and run the following commands

$ git clone https://github.com/sunshine-protocol/sunshine-keybase
$ cd sunshine-keybase && cd chain/client
$ cargo test --release

Here is an example of expected output. UnknownSubscriptionId errors are usually OK.
