How do I test Vue.js plugins effectively?

To test Vue.js plugins, you can use tools like Jest or Mocha along with Vue Test Utils. Would you like a code example?

Yes, please provide a code example for testing a simple Vue.js plugin.

Sure! Here's a basic example:

import { createLocalVue, mount } from '@vue/test-utils';
import MyPlugin from './my-plugin';

const localVue = createLocalVue();
localVue.use(MyPlugin);

test('plugin works correctly', () => {
  const wrapper = mount(MyComponent, { localVue });
  expect(wrapper.text()).toContain('Expected Output');
});

This tests if the plugin integrates correctly with a component.

What should I do if my tests are failing?

If your tests are failing, check for common issues like incorrect setup, missing dependencies, or errors in your plugin code. Debugging step-by-step can help identify the problem.
