```shell
npm run dev

## Complete code coverage with Cypress

When you run the application with `npm start` it instruments the source code using [@cypress/instrument-cra](https://github.com/cypress-io/instrument-cra) module. The code coverage is collected using [@cypress/code-coverage](https://github.com/cypress-io/code-coverage) plugin and saved in `coverage` folder.
