使用带有表单输入元素的ReactBootstrap模式对React组件进行单元测试

import React from 'react';
import { render, fireEvent } from '@testing-library/react';
import { Form, Button } from 'react-bootstrap';
import ComponentName from './ComponentName';

describe('ComponentName', () => {
  it('should render correctly', () => {
    render(<ComponentName />);
    // Add assertions to verify the correct rendering
  });

  it('should have correct initial state', () => {
    const { getByLabelText } = render(<ComponentName />);
    const inputElement = getByLabelText('Input Label');
    // Add assertions to verify the initial state
  });

  it('should update state on user input', () => {
    const { getByLabelText } = render(<ComponentName />);
    const inputElement = getByLabelText('Input Label');
    fireEvent.change(inputElement, { target: { value: 'New Value' } });
    // Add assertions to verify the updated state
  });

  it('should call submit handler on form submission', () => {
    const handleSubmit = jest.fn();
    const { getByLabelText, getByText } = render(
      <ComponentName onSubmit={handleSubmit} />
    );
    const inputElement = getByLabelText('Input Label');
    const submitButton = getByText('Submit');
    fireEvent.change(inputElement, { target: { value: 'New Value' } });
    fireEvent.click(submitButton);
    expect(handleSubmit).toHaveBeenCalledWith('New Value');
  });
});
