Answer 1

You get that error because your controller in test is never defined. You need to use var controller = ...
You should use controller injection like this :
beforeEach(inject(function(_$rootScope_,_$controller_){
$scope = _$rootScope_.$new();
createController = function() {
return _$controller_('EcdreportController', {
$scope : $scope
});
};
}));
and initialize the controller in each test like this :
it('Should be registered', function(){
var controller = new createController();
expect(controller).toBeDefined();
})
This way you can also pass on different parameters in each test if your controller requires any data to be passed on to.
