Running E2E tests

⚠️ Note: This guide supports ink! v5 by default. For experimenting with ink! v6, please refer to our migration guide.

Make sure you are in your contract's directory:

cd flipper

If you look at the contract source, you will notice it has end-to-end tests at the end of the lib.rs file.

The ink! e2e tests are run against substrate-contracts-node. Pop CLI will download the latest release binary for your platform.

Run the e2e tests:

 pop test contract --e2e
