What are some examples of Test-Driven Development in Vue.js?

Test-Driven Development (TDD) in Vue.js involves writing tests before implementing features. For example, you can start by writing a test for a component that displays a list of items.

Can you show me a simple test case for a Vue component?

Sure! Here's a simple test case using Jest and Vue Test Utils:

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

describe('MyComponent.vue', () => {
  it('renders a list of items', () => {
    const items = ['Item 1', 'Item 2'];
    const wrapper = shallowMount(MyComponent, { propsData: { items } });
    expect(wrapper.findAll('li').length).toBe(items.length);
  });
});

What tools do I need to get started with TDD in Vue.js?

You'll need a testing framework like Jest, and Vue Test Utils for component testing. You can also use Cypress for end-to-end testing.

Are there any best practices for TDD in Vue.js?

Yes! Some best practices include writing clear and concise tests, keeping your tests isolated, and ensuring your tests cover both happy and edge cases.
