[FEATURE] Flow Emulator Test Environment

[tombeckenham]

Issue to be solved

Currently we are performing testing manually on testnet and mainnet. As we start to introduce automated testing, we need a way of creating and using accounts (wallets) that have specific conditions such as specific balances, coins, or nfts. We then need to be able to move and send nfts and tokens repeatedly and expect the same result.

Whatever solution we come up with has to work both with unit tests (using vitest) and with e2e testing (using playwright). Unit tests are run automatically using vitest as part of the ci process.

We have just setup e2e testing using playwright, but the branch / PR is yet to be merged (as of when this issue has been created).

Suggest A Solution

There are several ways we can approach a solution.

I'd suggest one of these solutions:

1. Use the Flow emulator to run the tests, or
2. Create a set of mock data that can be loaded used by tests. You may be able to use flow emulator to generate this data

Please work with @Peppermint1020 to come up with the data sets and conditions.

It would be ideal if we can avoid having to create a separate test build but it may be unavoidable. If so, this build should be created in parallel on ci to the main build.

The solution should work on CI, AND locally so that engineers can run tests in watch mode locally.
