## Send Money Use Case

```gherkin

Feature: Send Money

  Scenario: Transaction succeeds

    Given a source account

    And a target account

    When money is send

    Then send money succeeds

    And source account is locked

    And source account withdrawal will succeed

    And source account is released

    And target account is locked

    And target account deposit will succeed

    And target account is released

    And accounts have been updated

```
