Mock document.referrer Angular Jasmine

Question

I am trying to provide a different value for

document.referrer

for my unit tests. How can I mock it and provide a customized value?

Answer 1

Inspecting document.referrer, we find that it is a getter:

With Jasmine 2.6, you can create a spy to change the return value of any getter functions.

spyOnProperty(document, 'referrer', 'get').and.returnValue('http://foobar.com');
expect(document.referrer).toBe('http://foobar.com');

You can read more in the latest API documentation.
