How do I test that the method has been called in jasmine?

I think you want to use toHaveBeenCalledWith():

it("should show that method doSomething is called with zero arguments", function() {
    // Ensure the spy was called with the correct number of arguments
    // In this case, no arguments
    expect(func.doSomething).toHaveBeenCalledWith();
});

If spy function has been called exactly once, use toHaveBeenCalledOnceWith matcher:

expect(mySpy).toHaveBeenCalledOnceWith('', 'link', "1", "1");

---

It combines toHaveBeenCalledTimes(1) and toHaveBeenCalledWith() matchers.

Coming with Jasmine 3.6.
