How do I configure Jest for a Vue 3 project?

To configure Jest for a Vue 3 project, you need to install the necessary packages like jest, vue-jest, and babel-jest. Would you like a step-by-step guide?

Yes, please provide the steps.

First, install the packages using npm or yarn:

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

Next, create a jest.config.js file in your project root with the following content:

module.exports = {
  moduleFileExtensions: ['js', 'json', 'vue'],
  transform: {
    '^.+\.vue$': 'vue-jest',
    '^.+\.js$': 'babel-jest',
  },
};

What about testing single-file components?

For testing single-file components, you can use @vue/test-utils to mount your components in your tests. Would you like an example?
