Jasmine - How to spy on a function call within a function?

Question

The following is in my controller:

$scope.addRangesAndSquare = function() {     $scope.addLeftRange();     $scope.addCenterSquare();     $scope.addRightRange(); } 

And I want to spy on $scope.addLeftRange(), so that when $scope.addRangesAndSquare is called so is $scope.addLeftRange():

it('expect addLeftRange to be called after calling addRangesAndSquare', function () {     spyOn(scope ,'addRangesAndSquare');     spyOn(scope, 'addLeftRange');     scope.addRangesAndSquare();     expect(scope.addLeftRange).toHaveBeenCalled(); }); 

How can this be done?

Answer 1

By default, when you use spyOn with jasmine, it mocks that function and doesn't actually execute anything within it. If you want to test further function calls within, you'll need to call .andCallThrough(), like so:

spyOn($scope, 'addRangesAndSquare').andCallThrough(); 

that should do it.
