How to unit test angularjs controller with $location service

Answer 1

This is how my test ended up working.

describe('OpponentsCtrl', function() {
    var scope, rootScope, ctrl, location;

    beforeEach(inject(function($location, $rootScope, $controller) {
        location = $location;
        rootScope = $rootScope;
        scope = $rootScope.$new();
        ctrl = $controller(OpponentsCtrl, {$scope: scope});
    }));

    it('should change location when setting it via show function', function() {
        location.path('/new/path');
        rootScope.$apply();
        expect(location.path()).toBe('/new/path');

        // test whatever the service should do...
        scope.show('/test');
        expect(location.path()).toBe('/test');

    });
});
