为调用fs writeFile的编辑函数编写单元测试

const fs = require('fs');
const { editAndWriteFile } = require('./your-module');

describe('editAndWriteFile', () => {
  it('should write data to file', () => {
    const filePath = 'test.txt';
    const data = 'Hello, World!';

    editAndWriteFile(filePath, data);

    const fileContent = fs.readFileSync(filePath, 'utf8');
    expect(fileContent).toEqual(data);
  });

  it('should handle errors when writing to file', () => {
    const filePath = 'nonexistent-directory/test.txt';
    const data = 'Hello, World!';

    expect(() => {
      editAndWriteFile(filePath, data);
    }).toThrow();
  });
});
