End-to-end tests

[han-so1omon]

What needs to be done

Run end-to-end tests with Lisbon or Berlin testnet on new release version

Why it needs to be done

Currently there are no end-to-end tests in a live environment. As a result, there are too many day-zero bugs

Acceptance Criteria

• Establish end-to-end tests using a framework capable of making live RPC calls, such as axios or postman
• Ensure that all [integration/regression tests] are running in the live test environment, replacing mock responses with real responses where appropriate (for example with the testnet version of Balanced)
• Ensure that end-to-end tests run as a part of the contract and frontend release pipelines
• Ensure that release pipeline only succeeds when end-to-end tests yield Success
