Bank Account Transfer System

A bank account transfer system that uses Cloud Datastore transactions to safely transfer money between accounts with automatic rollback on failures.

Capabilities

Account Management

  • Creating an account with ID "acc1" and initial balance 1000 stores the account in datastore and returns the account balance as 1000 @test

Successful Transfers

  • Creating two accounts with balances 1000 and 500, then transferring 300 from the first to the second results in final balances of 700 and 800 @test

Transfer Validation

  • Attempting to transfer 1500 from an account with balance 1000 raises an Exception and leaves both account balances unchanged @test
  • Attempting to transfer a negative amount -100 raises a ValueError @test

Transaction Rollback

  • When a transfer encounters an error after debiting the source account but before crediting the destination, the transaction rolls back and both accounts retain their original balances @test

Implementation
