Testing Nova custom tool

Testing a Nova custom tool, especially the frontend, can be a bit tricky since it involves a mix of Vue.js components and Laravel Nova's backend. However, you can approach this by using a combination of PHPUnit for the backend and Jest or Vue Test Utils for the frontend.

Here's a general approach to testing your Nova custom tool:

Backend Testing with PHPUnit

For the backend, you can write tests as you would for any other Laravel feature. Use PHPUnit to test your controllers, policies, and any other PHP code that your Nova tool relies on.

// Example PHPUnit test for a Nova tool controller

public function test_controller_returns_expected_response()
{
    $response = $this->get('/nova-vendor/my-custom-tool/endpoint');

    $response->assertStatus(200);
    $response->assertSee('Some expected content');
}

Make sure to set up your testing environment correctly, including any necessary configuration for Nova.

Frontend Testing with Jest and Vue Test Utils

For the frontend, you can use Jest alongside Vue Test Utils to test your Vue components. Here's a simple example of how you might test a Vue component:

1. Install Jest and Vue Test Utils if you haven't already:

npm install --save-dev jest vue-jest @vue/test-utils babel-jest

1. Configure Jest to handle .vue files by adding a jest.config.js file:

module.exports = {
  moduleFileExtensions: [
    'js',
    'json',
    // tell Jest to handle `*.vue` files
    'vue'
  ],
  transform: {
    // process `*.vue` files with `vue-jest`
    '.*\.(vue)$': 'vue-jest',
    // process js with `babel-jest`
    '.*\.(js)$': 'babel-jest'
  }
};

1. Write a test for your Vue component:

import { shallowMount } from '@vue/test-utils';
import MyCustomComponent from '@/path-to-your-component/MyCustomComponent.vue';

describe('MyCustomComponent', () => {
  test('renders correctly', () => {
    const wrapper = shallowMount(MyCustomComponent);
    expect(wrapper.element).toMatchSnapshot();
  });

  // Add more tests to verify functionality, like event handling, computed properties, etc.
});

1. Run your Jest tests:

jest

Remember to mock any dependencies your components might have, such as API calls or other Nova-specific functionality. You can use jest.mock() to mock modules or mockImplementation() to mock functions.

By combining PHPUnit for backend tests and Jest with Vue Test Utils for frontend tests, you can comprehensively test your Nova custom tool. Make sure to write tests as you develop to ensure that each part of your tool is working as expected.
