Native builds not working using npm run ionic-e2e:build:android

Question

I have an Ionic Angular mobile app and i want to execute native tests using the npm run ionic-e2e:build:android and npm run ionic-e2e:run:android commands but im getting the following error:

npm ERR! Missing script: "ionic-e2e:run:android"
npm ERR!

Do i need to install something else in order to make it work?

I am following this guide: https://ionicframework.com/blog/introducing-the-ionic-end-to-end-testing-reference-example/

Thanks in Advance
