Run e2e tests

Before you can run the test, you have to install a Substrate node with pallet-contracts. By default, e2e tests require that you install substrate-contracts-node. You do not need to run it in the background since the node is started for each test independently. To install the latest version:

cargo install contracts-node --git https://github.com/paritytech/substrate-contracts-node.git

If you want to run any other node with pallet-contracts you need to change CONTRACTS_NODE environment variable:

export CONTRACTS_NODE="YOUR_CONTRACTS_NODE_PATH"

And finally execute the following command to start e2e tests execution.

cd integration_tests
cargo test --features e2e-tests
