How can I test APIs in a Vue.js application?

You can use libraries like Axios for making API calls and Jest or Mocha for testing your Vue components.

Can you show me an example of a test case?

Sure! Here's a simple test case using Jest:

import { shallowMount } from '@vue/test-utils';
import MyComponent from '@/components/MyComponent.vue';

test('fetches API data', async () => {
  const wrapper = shallowMount(MyComponent);
  await wrapper.vm.fetchData();
  expect(wrapper.vm.data).toBeDefined();
});

What about mocking API responses?

You can use libraries like jest.mock to mock Axios calls. This way, you can simulate API responses without making real requests.

Are there any best practices for API testing in Vue?

Yes! Some best practices include testing edge cases, using mock data, and ensuring your tests are isolated and repeatable.
