E2E Testing: Fungible Token Flows

[TrevorJTClarke]

Unit Tests

• Add unit tests here: https://github.com/Cron-Near/treasury/blob/main/treasury/src/ft_impl.rs#L205
• Test: Can prepare for future tests: deploy basic FT, mint balance to need holders: dao, treasury, etc
• Test: can store_ft_balance_of
• Test: can get ft_balances
• Test: Can get list o supportedf ft tokens: get_ft_list
• Test: Can get list of ft tokens & its balances: ft_balances
• Test: Can make an FT transfer: ft_transfer

Workspace Tests

• Add tests here: https://github.com/Cron-Near/treasury/blob/main/e2e/src/ft_impl.rs
• Test Flow: Receive & Transfer
  • Mint some default tokens to an account
  • update internal balances using store_ft_balance_of
  • Check list of supported FT tokens get_ft_list
  • Check balances of FT tokens ft_balances
  • Transfer some FT tokens (ft_transfer) & validate (directly on the FT contract, with ft_balance_of)

Security Implications:

• TBD - TC

Examples:

# FT balance is stored on each token account, to help these are fns that can retrieve and maintain that snapshot to be used for internal accounting.
