   and its [IBC structs](https://github.com/cosmos/ibc-go/tree/main/proto/ibc).
 - The [`ibc-telemetry`][ibc-telemetry-crate-link] crate is a library for use in the `hermes` CLI,
   for gathering telemetry data and exposing that in a Prometheus endpoint.
+- The [`ibc-test-framework`][ibc-test-framework-crate-link] crate provides the infrastructure and framework for writing end-to-end (E2E) tests that include the spawning of the relayer together with Cosmos full nodes.
 
 See the table below for more details.
 
 Includes [TLA+ specifications](docs/spec).
