javascript - Migrate to angular 2 -


i got legacy application written in angular 1 needs fixed.

i'm required write unit tests in order modifications app, questions are:

  1. is there framework can use write unit tests works in angular 1 , 2 without having modify them (or not much).
  2. how migrate thing? without having work, administration says should kept on angular 1, find angular 1 not angular 2 (probably because 2 reminds me of react more, , i'm react developer). thing every single page has module, controller , view (yes every single page), there no reusable components whatsoever, uses history api routing (in tangled way), if how change page page use angular 2 instead of 1?

eg. module

angular.module('catmodule') .config(function ($stateprovider) {   $stateprovider     .state('cats', {       url: '/cats',       templateurl: 'cats/cats.html',       controller: 'catsctrl',       authenticate: true     }); });

controller:

angular.module('catmodule') .controller('catsctrl', function ($scope, $http, $firebaseobject) {    $scope.catnumber = 10;     //main spagetthi here... d: });

view:

<div>we got {{catnumber}} cats</div>

i need rough ideas, no need specific; have figure out things myself later anyway.

there's no such thing universal unit tests, need write different ones, doesn't mean can't copy or re-use of logic. best thing do, following official migration guide. can have 2 different versions working alongside. hardest part setting webpack , tooling, if not used that.

my advice? don't try fix isn't broken. angular 1 being used since 2009, lot has changed since then, it's still framework. if admnistration not willing move angular 2 , don't have support, keep doing angular 1.

because migration going stumble upon lot of difficulties, have learn angular 2, webpack, typescript , although go angular without typescript, won't find as documentation. have make 2 frameworks work alongside , re write unit tests. think twice before jumping migration.

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
