Wait for finalized on transfer of money for tests

e2e-tests/README.md

@@ -7,10 +7,29 @@ This crate contains e2e test scenarios for the aleph-node.
 The most basic way to run (assuming a local node is listening on 9944) is:
 
 ```bash
-$ NODE=ws://127.0.0.1:9944 cargo test name_of_one_test
+$ NODE_URL=ws://127.0.0.1:9944 cargo test name_of_one_test
 ```
 
 Note that the particular test cases might require different numbers of launched nodes, validators, or a particular
 configuration of the launched nodes, see the documentation for a particular test case for details.
 
 Additional options are passed to the tests via env variables. See `src/config.rs` for docs on available options.
+
+## Running on devnet (or other-net)
+
+You can also run the tests on some other network. For example, to run the contract test for the `adder` contract on
+devnet:
+
+1. Prepare an account with some money, note the seed of the account.
+2. Deploy the contract to devnet:
+
+```bash
+contracts/adder$ NODE_URL=wss://ws.dev.azero.dev AUTHORITY="$THE_SEED" ./deploy.sh
+```
+
+3. Run the tests:
+
+```bash
+e2e-tests$ RUST_BACKTRACE=1 SUDO_SEED="$THE_SEED" NODE_URL=wss://ws.dev.azero.dev:443 \
+  ADDER=$DEPLOY_ADDRESS ADDER_METADATA=../contracts/adder/target/ink/metadata.json cargo test adder -- --nocapture
+```
