Repository to hold XCM activities and exercises for the Polkadot Blockchain Academy.
Inside each folder module you will either find a README.md file describing the activity/coding exercise or you will find a coding exercise itself to be done.
For most of these exercises you will be using the xcm-simulator.
The xcm-simulator allows you to create a test environment in which to test messages received between two runtimes.
You can use the decl_test_parachain macro to declare a parachain specifying the runtime, router and test-externality to use.
You can use the decl_test_relay_chain macro to declare a parachain specifying the runtime, xcmConfig and test-externality to use.
Finally the decl_test_network macro allows you to create a network with the parachains and relay declared.
You can take a look at the main example for the exercises to get a sense on how the simulator works.
