        $scope.name = 'bob';

Answer 1

Try:

beforeEach(module('myApp'));

instead of:

beforeEach(module('myapp.controllers'));

Answer 2

I'm just guessing here, as I don't have Phantom to run on Linux... but $scope is expected to be a Scope object.

Try injecting $rootScope , and either use that, or create a $new() child scope from it:

beforeEach(inject(function($controller, $rootScope) {
    //get controller from $controller provider
    scope = $rootScope.$new(); 
    ctrl = $controller('IndexController', {
        $scope: scope
    }); 
}));
