ibc-testkit 0.57.0

Maintained by `ibc-rs`, serves as a versatile library that provides essential abstractions and implementations, fulfilling a dual role of enabling rigorous integration testing for the `ibc-rs` implementation while also aiding host chains in addressing a broad spectrum of testing scenarios during their integrations with `ibc-rs`.
