It seems like you're using a project generated using an old version of the Angular CLI.
The latest CLI now uses webpack and has a lot of improvements including a simpler
workflow, a faster build, and smaller bundles.

To get more info, including a step-by-step guide to upgrade the CLI, follow this link:

I had the same issue, to fix it I had to

1. update ionic cli to the latest version
2. create a new project: https://ionicframework.com/docs/v2/intro/installation/
3. replace the src directory in the new project with your existing one (delete src/app/main.dev.ts, main.prod.ts if you have them, you don’t need them in the newer versions)
4. set up the testing environment: https://www.joshmorony.com/introduction-to-testing-ionic-2-applications-with-testbed/ or https://github.com/lathonez/clicker
5. ng test

EDIT:

I found out the tests were working because I had the latest @angular/cli installed globally, and I was running the commands with ng test. I am still trying to make it work with local version. By then try to npm install -g @angular/cli and then ng test
