Question

How can I spy on a getter property using jasmine?

var o = { get foo() {}, };

spyOn(o, \'foo\').and.returnValue(\'bar\'); // Doesn\'t work.

Answer 1

You can do this if you are unable to use the latest jasmine (2.6.1)

const getSpy = jasmine.createSpy().and.returnValue('bar')
Object.defineProperty(o, 'foo', { get: getSpy });
