Basic Example

Let's use launchTestNode with the counter contract from the Fuel dApp tutorial.

Note: you will have to change the import paths of the contract factory and bytecode to match your folder structure.

Summary

1. The launched variable was instantiated with the using keyword.
2. launchTestNode spun up a short-lived fuel-core node, deployed a contract to it and returned it for testing.
3. The deployed contract is fully typesafe because of launchTestNode's type-level integration with typegen outputs.
4. Besides the contract, you've got the provider and wallets at your disposal.
