So far the `bridge-hub-test-utils` contained a tests set for testing BridgeHub runtime that is bridging with the remote **parachain**. But we have https://github.com/paritytech/polkadot-sdk/pull/2540 coming, which would add Rococo <> Bulletin chain bridge (where Bulletin = standalone chain that is using GRANDPA finality). Then it'll be expanded to Polkadot BH as well. So this PR adds the same set of tests to the `bridge-hub-test-utils`, but for the case when remote chain is the chain with GRANDPA finality. There's a lot of changes in this PR - I'll describe some: - I've added `BasicParachainRuntime` trait to decrease number of lines we need to add to `where` clause. Could revert, but imo it is useful; - `cumulus/parachains/runtimes/bridge-hubs/test-utils/src/test_data` is a submodule for generating test data for the test sets. `from_parachain.rs` is used in tests for the case when remote chain is a parachain, `from_grandpa_chain.rs` - for the bridges with remote GRANDPA chains. `mod.rs` has some code, shared by both types of tests; - `cumulus/parachains/runtimes/bridge-hubs/test-utils/src/test_data` is a submodule with all test cases. The `mod.rs` has tests, suitable for all cases. There's also `wth_parachain.rs` and `with_grandpa_chain.rs` with the same meaning as above; - I've merged the "core" code of two previous tests - `relayed_incoming_message_works` and `complex_relay_extrinsic_works` into one single `relayed_incoming_message_works` test. So now we are always constructing extrinsics and are dispatching them using executive module (meaning all signed extensions are also tested). New test set is used here: https://github.com/paritytech/polkadot-sdk/pull/2540. Once this PR is merged, I'll merge that other PR with master to remove duplicate changes. I'm also planning to cleanup generic constraints + remove some unnecessary assumptions about used chains in a follow-up PRs. But for now I think this PR has enough changes, so don't want to complicate it even more. --- Breaking changes for the code that have used those tests before: - the `construct_and_apply_extrinsic` callback now accepts the `RuntimeCall` instead of the `pallet_utility::Call`; - the `construct_and_apply_extrinsic` now may be called multiple times for the single test, so make sure the `frame_system::CheckNonce` is correctly constructed; - all previous tests have been moved from `bridge_hub_test_utils::test_cases` to `bridge_hub_test_utils::test_cases::from_parachain` module; - there are several changes in test arguments - please refer to https://github.com/paritytech/polkadot-sdk/compare/sv-tests-for-bridge-with-remote-grandpa-chain?expand=1#diff-79a28d4d3e1749050341c2424f00c4c139825b1a20937767f83e58b95166735c for details.

NOTE: We have recently made significant changes to our repository structure. In order to streamline our development process and foster better contributions, we have merged three separate repositories Cumulus, Substrate and Polkadot into this repository. Read more about the changes here.
Polkadot SDK
The Polkadot SDK repository provides all the resources needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way. The Polkadot SDK comprises three main pieces of software:
Polkadot
Implementation of a node for the https://polkadot.network in Rust, using the Substrate framework. This directory
currently contains runtimes for the Polkadot, Kusama, Westend, and Rococo networks. In the future, these will be
relocated to the runtimes repository.
Substrate
Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network. Additionally, it allows for the development of self-sovereign blockchains that operate completely independently of Polkadot.
Cumulus
Cumulus is a set of tools for writing Substrate-based Polkadot parachains.
