# Test Bulk Assignment

# Bulk Assignment Test

## Test Instructions

1. Open the TaskBrowser in the application
2. Select multiple tasks using checkboxes
3. Right-click on a selected task
4. Click "Assign To" in the context menu
5. Select a user from the submenu
6. Verify that:
   - A success toast appears showing the count of assigned tasks
   - The task list refreshes automatically
   - The context menu closes
   - The selection is cleared
   - The tasks now show the assigned user

## Implementation Checklist

- ✅ Created `handleBulkAssignment` method in TaskBrowser
- ✅ Extracts selected task IDs from selection state
- ✅ Calls `taskService.bulkAssignTasks` with task IDs and user ID
- ✅ Shows loading state during operation (`isLoading.value = true`)
- ✅ Displays success toast with count of assigned tasks
- ✅ Handles errors and displays error toast
- ✅ Refreshes task list after successful update (`await fetchTasks()`)
- ✅ Closes context menu after completion (`closeContextMenu()`)
- ✅ Clears selection after completion (`rowSelection.value = {}`)
- ✅ Connected to TaskBulkActionsMenu `@assignee-selected` event

## Requirements Validated

- ✅ Requirement 5.3: Updates all selected tasks to be assigned to the selected user
- ✅ Requirement 5.4: Displays success notification with count of tasks assigned
- ✅ Requirement 5.5: Displays error notification on failure and maintains original assignments
- ✅ Requirement 5.6: Refreshes task list to reflect changes
- ✅ Requirement 6.1: Closes context menu automatically after action
- ✅ Requirement 6.3: Clears task selections after action completes

## Error Handling

The implementation includes proper error handling:

- Try-catch block wraps the entire operation
- Loading state is properly managed in finally block
- Error toast displays user-friendly message
- Console logs detailed error for debugging
- Backend handles atomicity (all or nothing)
