wierd error when running unit test with ionic 2

Question

I'm building an ionic 2 application with karma and jasmine for unit testing and suddenly I get this error when running my unit tests.

Does someone know where the problem is and what the problem is?

Answer 1

The problem is that I used localStorage in my unit test. I deleted that and it fixed my problem.
