TypeError: Cannot read property 'length' of undefined

I'm getting following error when I run ng test in my angular 2 project .spec file.

Here is my .html => I used *ngIf="mylistobject.length < 1

<div *ngIf="mylistobject.length < 1">
        <p>No existing object</p>
</div>

Error:

@sithwin why do you think that problem in karma-jasmine?

In stack trace I see that problem in (ng:///DynamicTestModule/MemberFormComponent.ngfactory.js:518:36) at
