Mock date constructor with Jasmine

Question

I\'m testing a function that takes a date as an optional argument. I want to assert that a new Date object is created if the function is called without the argument.

Answer 1

for me it worked with:

spyOn(Date, 'now').and.callFake(function() {
    return _currdate;
  });

instead of .andCallFake (using "grunt-contrib-jasmine": "^0.6.5", that seems to include jasmine 2.0.0)
