Jest test with CKEditor problem while testing

If you are using TypeScript and trying to write Jest tests for code that involves CKEditor, you may encounter some difficulties. CKEditor is a popular rich text editor that allows users to format and style their text. However, when it comes to testing code that uses CKEditor, there are a few challenges that need to be addressed.

One common problem is that CKEditor is not easily mockable or configurable in a Jest test environment. This can make it difficult to test code that relies on CKEditor functionalities. However, there are a few solutions that can help you overcome this problem.

Solution 1: Mocking CKEditor

The first solution involves mocking CKEditor in your Jest tests. By creating a mock version of CKEditor, you can simulate its behavior and test your code without actually using the real CKEditor instance.

Here’s an example of how you can mock CKEditor in your Jest tests:

jest.mock('ckeditor', () => ({
  create: jest.fn(() => ({
    setData: jest.fn(),
    getData: jest.fn(),
    destroy: jest.fn(),
  })),
}));

This code creates a mock version of CKEditor’s create method, which returns an object with mock implementations of setData, getData, and destroy methods. You can customize these mock implementations as per your test requirements.

Solution 2: Using a Testing Library

Another solution is to use a testing library that provides utilities for testing code that involves CKEditor. One such library is @testing-library/react, which offers a set of testing utilities specifically designed for React applications.

Here’s an example of how you can use @testing-library/react to test code that uses CKEditor:

import { render, screen } from '@testing-library/react';
import CKEditor from 'ckeditor';

test('renders CKEditor component', () => {
  render();
  const editorElement = screen.getByRole('textbox');
  expect(editorElement).toBeInTheDocument();
});

In this example, we render the CKEditor component using @testing-library/react‘s render function and then use screen.getByRole to retrieve the editor element. Finally, we assert that the editor element is in the document using expect.

These are just two possible solutions to the problem of testing code that involves CKEditor in a Jest environment. Depending on your specific requirements and testing setup, you may need to explore other options or customize these solutions further.

Remember, testing is an essential part of the development process, and finding ways to effectively test code that involves external dependencies like CKEditor is crucial for maintaining code quality and reliability.

Happy testing!
