How can I test that a function has not been called?

Question

I'm testing router and have two functions, and I need to test if first function was called and second was not. There is method toHaveBeenCalled but there is no method to test if function was not called. How can I test that?

I have code like this:

var args, controller, router; beforeEach(function() {     controller = {         foo: function(name, id) {             args = [].slice.call(arguments);         },         bar: function(name) {         }     };     spyOn(controller, "foo").and.callThrough();     spyOn(controller, "bar").and.callThrough();     router = new route();     router.match('/foo/bar/{{id}}--{{name}}', controller.foo);     router.match('/foo/baz/{{id}}--{{name}}', controller.bar);     router.exec('/foo/bar/10--hello'); }); it('foo route shuld be called', function() {     expect(controller.foo).toHaveBeenCalled(); }); it('bar route shoud not be called', function() {     // how to test if bar was not called? }); 

Answer 1

Use the not operator:

expect(controller.bar).not.toHaveBeenCalled();
