Unit testing @Page throws exception

Ionic Framework ionic-v3
1

Hi all,

When running my unit test for a piece of implementation annotated as Page, the compiled JavaScript throws ionic_angular_1.Page is not a function.

I spent a couple days setting up a build pipeline and used @lathonez setup (GitHub - lathonez/clicker: Ionic 2 + @angular/cli Seed Project : Angular2 + Typescript + Karma + Protractor + Travis) as inspiration. It could be that I missed something.

Does anybody know what the reason is for this exception?
Is there a dependency for dealing with decorators?

Any pointers are appreciated!
Ben

The stracktrace for completeness:

Hey Ben,

If you raise an issue against the clicker repo I’ll do my best to help out.

Can you paste in your package.json when you raise it?

Cheers
