Create Postman collection to test every single endpoint in the BankAccountAccess module

### Creating a Postman Collection for Testing Endpoints in the `BankAccountAccess` Module

To thoroughly test the endpoints in the `BankAccountAccess` module, we'll create a structured Postman collection. This collection will include tests for creating, modifying, viewing, and deleting `BankAccountAccess` objects, as well as testing various roles such as `HolderAccess`, `SeniorManagerAccess`, `ManagerAccess`, `AgentAccess`, `AuditorAccess`, and `PoAAccess`.

Here's a detailed approach to creating the Postman collection for each of these operations:

### 1. **Base URL and Environment Setup**
- First, define your environment variables in Postman:
- `base_url`: The base URL for your API, e.g., `http://localhost:8080/api/`
- `token`: An authorization token for secure endpoints if necessary.

The base structure for all requests would be `{{base_url}}/bank-account-access`.

### 2. **Create BankAccountAccess**
- **Endpoint**: `POST /bank-account-access`
- **Description**: This endpoint is used to create a `BankAccountAccess` entry.
- **Request Body**:
```json
{
"accountId": "12345",
"entityId": "67890",
"scope": ["read_balance", "manage_access", "execute_payment"],
"weight": 1.0,
"conditions": {
"monetary_limit": 10000,
"time_constraint": "2024-12-31",
"location_constraints": ["US", "EU"]
},
"status": "active",
"policies": ["standard_policy"]
}
```
- **Test Scenarios**:
- Successfully create a new `BankAccountAccess` entry.
- Handle validation errors (e.g., missing `accountId` or `entityId`).

### 3. **Get All BankAccountAccess Records**
- **Endpoint**: `GET /bank-account-access`
- **Description**: This endpoint retrieves a list of all `BankAccountAccess` entries.
- **Test Scenarios**:
- Retrieve the list of all bank account access records.
- Handle empty lists if no access records exist.

### 4. **Get Specific BankAccountAccess by ID**
- **Endpoint**: `GET /bank-account-access/{id}`
- **Description**: Retrieves a specific `BankAccountAccess` entry by its ID.
- **Path Variable**: `{id}` is the unique ID of the `BankAccountAccess` entry.
- **Test Scenarios**:
- Successfully retrieve a specific `BankAccountAccess` entry.
- Handle cases where the `BankAccountAccess` entry does not exist (404 error).

### 5. **Update BankAccountAccess**
- **Endpoint**: `PUT /bank-account-access/{id}`
- **Description**: Updates an existing `BankAccountAccess` entry.
- **Path Variable**: `{id}` is the unique ID of the `BankAccountAccess` entry to update.
- **Request Body**:
```json
{
"scope": ["read_balance", "execute_payment"],
"weight": 0.5,
"status": "restricted"
}
```
- **Test Scenarios**:
- Successfully update an existing `BankAccountAccess` entry.
- Handle validation errors for invalid or incomplete updates.

### 6. **Delete BankAccountAccess**
- **Endpoint**: `DELETE /bank-account-access/{id}`
- **Description**: Deletes a `BankAccountAccess` entry by its ID.
- **Test Scenarios**:
- Successfully delete an existing `BankAccountAccess` entry.
- Handle attempts to delete non-existing entries (404 error).

### 7. **Test Scenarios for Access Roles**

#### 7.1 **HolderAccess**
- **Endpoint**: `POST /bank-account-access/holder-access`
- **Description**: This endpoint automatically creates `HolderAccess` when a new account is created.
- **Test Scenarios**:
- Create an account and ensure that `HolderAccess` is automatically generated.
- Suspend `HolderAccess` when transferring account ownership.

#### 7.2 **SeniorManagerAccess**
- **Endpoint**: `POST /bank-account-access/senior-manager-access`
- **Description**: Creates `SeniorManagerAccess` for managing `ManagerAccess` roles.
- **Test Scenarios**:
- Successfully create `SeniorManagerAccess`.
- Test updating or suspending `SeniorManagerAccess`.

#### 7.3 **ManagerAccess**
- **Endpoint**: `POST /bank-account-access/manager-access`
- **Description**: Creates and manages `ManagerAccess` for the account.
- **Test Scenarios**:
- Successfully create and modify `ManagerAccess`.
- Limit the scope of `ManagerAccess` to prevent unauthorized actions.

#### 7.4 **AgentAccess**
- **Endpoint**: `POST /bank-account-access/agent-access`
- **Description**: Grants `AgentAccess`, allowing the agent to impersonate the holder in specific processes.
- **Test Scenarios**:
- Test the creation of `AgentAccess` and ensure it does not grant permission to manage access.

#### 7.5 **AuditorAccess**
- **Endpoint**: `POST /bank-account-access/auditor-access`
- **Description**: Grants read-only access to auditors for reviewing account data.
- **Test Scenarios**:
- Test that auditors can view account data without modifying it.
- Validate that unauthorized users cannot access the same data.

#### 7.6 **PoAAccess**
- **Endpoint**: `POST /bank-account-access/poa-access`
- **Description**: Grants `Power of Attorney` access, allowing the user to act on behalf of the account holder.
- **Test Scenarios**:
- Create and test `PoAAccess` with different scopes.
- Ensure revocation of `PoAAccess` is handled properly.

### 8. **Error Handling and Edge Cases**
- Include tests for:
- Invalid data (e.g., missing fields or incorrect formats).
- Unauthorized access (e.g., attempting to modify access without proper permissions).
- Expired or suspended access statuses.

### 9. **Testing Open Banking Use Cases (Optional)**
- Since `PoAAccess` and `ThirdPartyAccess` can implement open banking concepts, you can include additional test cases for:
- **Account Information Consent** (read-only access to account information).
- **Payment Initiation Consent** (initiating payments on behalf of the account holder).
- **Confirmation of Funds Consent** (verifying available funds).

### 10. **Postman Collection Structure**
Organize the Postman collection into folders for easy navigation:
- **Authentication**: If your API requires authentication, have a folder for login and token generation.
- **BankAccountAccess**:
- `POST` Create `BankAccountAccess`.
- `GET` All `BankAccountAccess` entries.
- `GET` BankAccountAccess by ID.
- `PUT` Update `BankAccountAccess`.
- `DELETE` Delete `BankAccountAccess`.
- **Access Roles**:
- HolderAccess.
- SeniorManagerAccess.
- ManagerAccess.
- AgentAccess.
- AuditorAccess.
- PoAAccess.

### 11. **Environment Variables and Pre-Scripts**
- Use Postman environment variables (e.g., `{{token}}`, `{{base_url}}`) to make the requests reusable across different environments (development, staging, production).
- Include pre-scripts to handle token refresh or any required setup steps before making the API requests.
