#### 3. DataElementForm.test.tsx
```typescript
import React from 'react'
import { render, screen, fireEvent, waitFor } from '@testing-library/react'
import userEvent from '@testing-library/user-event'
import { DataElementForm } from './DataElementForm'
// Mock the DHIS2 hooks
jest.mock('@dhis2/app-runtime', () => ({
useDataMutation: () => [
jest.fn().mockResolvedValue({ success: true }),
{ loading: false }
]
}))
describe('DataElementForm', () => {
const mockOnSubmit = jest.fn()

})
it('renders all form fields', () => {

#### 4. Usage Example
```typescript
import React, { useState } from 'react'
import { DataElementForm } from './components/DataElementForm'
import { AlertBar } from '@dhis2/ui'
export const DataElementsPage: React.FC = () => {
const [showForm, setShowForm] = useState(false)
const [message, setMessage] = useState<string | null>(null)
const handleFormSubmit = (result: any) => {
setMessage('Data element created successfully!')
setShowForm(false)
setTimeout(() => setMessage(null), 5000)
}
return (
<div className="data-elements-page">
<h1>Data Elements Management</h1>
{message && (
<AlertBar success duration={5000}>
{message}
</AlertBar>
)}
{showForm ? (
<DataElementForm onSubmit={handleFormSubmit} />
) : (
<Button primary onClick={() => setShowForm(true)}>
Create New Data Element
</Button>
)}
</div>
)
}
```
