I am setting up a new solution with Angular 6, Karma and Jasmine. However to my surprise the specs list is getting the following class as undefined:

```
<li class="undefined" id="spec-spec1" spec-suite-id="suite3">
<a href="?spec=Router%3A%20App%20looks%20async%20but%20is%20synchronous">
   looks async but is synchronous
</a>
</li>

```

Using Angular 5 the result looks as follows: Specs that are running are clearly shown in green and skipped spec are shown in grey

How to debug this in Angular 6 generated test using CLI ?
