How can I test Vue 3 components effectively?

You can use tools like Vue Test Utils and Jest to test Vue 3 components. Would you like a brief overview of how to set them up?

Yes, please explain how to set up Vue Test Utils.

First, install Vue Test Utils and Jest using npm. You can run npm install --save-dev @vue/test-utils jest. Then, create a test file for your component.

What should I include in the test file?

In the test file, import your component and Vue Test Utils. Write tests using describe and it blocks to check the component's behavior.

Can you give me an example of a simple test?

Sure! Here's a simple test: it('renders a message', () => { const wrapper = mount(MyComponent); expect(wrapper.text()).toContain('Hello World'); });
