angular-mock 1.5.1 TypeError: undefined is not a constructor (evaluating 'angular.element.cleanData(cleanUpNodes)')

[lazarDevelopment]

My Tests working fine with angular-mock 1.5.0 but with 1.5.1 all Tests fail with:
TypeError: undefined is not a constructor (evaluating 'angular.element.cleanData(cleanUpNodes)') in ../node_modules/angular-mocks/angular-mocks.js (line 2776) $$cleanup@../node_modules/angular-mocks/angular-mocks.js:2776:32 $$afterEach@../node_modules/angular-mocks/angular-mocks.js:2746:23

[petebacondarwin]

That is strange, since no constructor is being called in that bit of code. Perhaps you can provide some more information? A copy of a failing test, preferably one that we can run.

[lazarDevelopment]

Here you can find a test, it does nothing but every test we have fails (only for version 1.5.1, 1.5.0 is fine).

[Narretz]

It looks like you are using ui-router, is that right?
Can you try to create a test that runs here: http://plnkr.co/edit/tpl:vojSWqpk1yBjQbbPeXRH?

As a suggestion, you should also try to remove dependencies from your test, and see what exactly triggers the error (you have a lot of dependencies in the application module)

[lazarDevelopment]

Yes, using angular-ui-router(0.2.18).
Trommorow I will try to find the dependency who causes it.

+1, I am receiving a very similar error trying to test a provider.

Edit: This error occurs with ver 1.5.1, I switched back to 1.5.0 and everything works again.

@petebacondarwin undefined is not a constructor is the cryptic error PhantomJS gives when you try to call a function that is not defined. It's equivalent to Chrome's a.something is not a function error.

We're getting a similar error on Angular/Mock 1.5.1, which is not an issue on 1.5.0:

Note that we use jQuery alongside Angular.

Could this be at all related to 75373dd?

[mgol]

@nikrolls

angular.element(...).data is not a function

Do I understand it right that angular.element(...) (which is aliased to jQuery(...) if you load jQuery before Angular) returns something that doesn't have the data method? That seems weird. Could you enable "break on rejections" in Chrome DevTools and then, when you hit this line, check what exactly return the following expressions:

1. angular.element
2. angular.element(...) (substitute the dots with what you really have there)
3. ... (substitute the dots with what you had in angular.element)

Thanks!

We have a similar problem since angular v1.5.1.

        undefined

In this case the error is always thrown when the tests includes the inject() function. I guess the spyOn($location, 'path'); in the beforeEach function could be the problem.

describe('ctrl test', function () {
    beforeEach(inject(function ($controller, $location) {
        spyOn($location, 'path');
    }));

    describe('save()', function () {
        it('should work', function(){
            inject(function ($location) {
                // some test code
            });
        });
    });
});

[petebacondarwin]

@4kochi - you problem is actually that you have spied on a function but not provided an implementation for the spy. In other words, calling spyOn($location, path); overrides the $location.path method with a spy function but that spy function returns undefined. Later the router is trying to access $location.path().search, which is effectively saying undefined.search.

You need to provide an implementation for the spy: either a fake or a pass-through:

spyOn($location, 'path').andCallThrough();
spyOn($location, 'path').andCallFake(function(url) { return {...}; });

[4kochi]

Thanks for the tip @petebacondarwin I had an similar idea. But I wonder then why the exact same test code works with Angular 1.5.0? Did I miss something?

[dagda1]

I have the same issue when I use inject,e.g.

  beforeEach(inject(function($rootScope) {

  }));

[gkalpak]

@dagda1, could you provide the info mentioned in #14251 (comment) (as well as the exact stack trace for the error) ?

[KeithPepin]

I was seeing this problem as well with our tests after trying to upgrade to v1.5.2. Changing line 2776 of angular-mocks.js from:
angular.element.cleanData(cleanUpNodes);
To:
if (angular.element.cleanData) angular.element.cleanData(cleanUpNodes);

Fix the issue. In our case, we're trying to spy on angular.element for various reasons.

[gkalpak]

In our case, we're trying to spy on angular.element for various reasons.

That explains the error.

angular.element is a pretty basic "feature" and relied upon heavily internally. I wouldn't recommend stubbing it out. (Spying on it and letting things pass through should be OK though).

[gkalpak]

BTW, changing the code to if (angular.element.cleanData) angular.element.cleanData(cleanUpNodes); leads to memory leaks that can cause karma to crash on huge testsuites.
(Yes, it has happened already 😃)

[KeithPepin]

Thanks @gkalpak - unfortunately any sort of spy (even one that only calls through) seems to cause the same issue. Is there any other work around in the works or other suggestions to try?

[petebacondarwin]

@KeithPepin angular.element is a tricky beast. Do you really need to spy on it? Can you give an example of your tests?

[prestonvanloon]

@gkalpak thank you!

[varunlakhan]

@prestonvanloon : Check the version of angular and angular-mocks you are using. I was facing the same issue. When I was using angular-mocks version 1.5.5 and angular version was 1.4.7, I got the same exception. When I upgraded my angular version to 1.5.5, I did not get any errors and all the tests ran successfully.

[prestonvanloon]

Thanks @varun85jobs and @gkalpak, that was exactly my issue

[hristo-vrigazov]

Hey guys, I have an Ionic project with angular version 1.5.3 and angular-mocks 1.5.3, but I still get the same error. What could it be?

[gil13]

Hi, same problem here, I have just tried with 1.5.5 and 1.5.3 and still with problems, as temporal solution we use 1.5.0.

[hristo-vrigazov]

KeithPepin's answer fixed it for me, but I prefer not to change a library's code

[petebacondarwin]

We still don't have a proper use case for spying on angular.element. Without this we can't move forward with a fix.

[yishaic]

There is a question about this issue here as well.
My answer from there, in case it will help anyone here:

I had the same problem and what fixed it to me was to load jquery in my tests:

files: [
      'bower_components/jquery/dist/jquery.js',
      'bower_components/angular/angular.js',
      'bower_components/angular-mocks/angular-mocks.js',
...
]

took the idea from this comment because we also use jQuery alongside Angular.

[petebacondarwin]

We still need an actual running reproduction, where all the versions of angular modules used match.

[kristoff2016]

I got this issue: angular.element.parent is not a function

[gkalpak]

@kristoff2016, this doesn't seem like the same problem. Please open a new issue, providing more info, e.g. the relevant code, the exact error message, your environament (browser, OS etc). Live reproductions (using CodePen, Plnkr etc) are highly appreciated as well 😁

[oliamb]

In my case, the issue was that I was using an old version of karma-phantomjs-launcher (^0.1.4 instead of ^1.0.0) which relied on an older version of PhantomJS. With [email protected], it is working properly.

[mcranston18]

+1 upgrading karma-phantomjs-launcher and phantomjs to 2+ did the trick

[vitorarins]

The only option that worked for me until now was downgrading to angular/angular-mocks 1.5.0

[gkalpak]

It's been months since this was first reported and there is still no actual reproduction (with matching versions) posted here!! We can't fix what we can't see. 😟

I am going to close this, but would be happy to re-open if we get a reproduction.

[vitorarins]

Hi @gkalpak, thanks for taking the time. I was able to reproduce the problem, but apparently we were doing something really naughty in our code 🙈. I have saved in this plnkr. So the following code may not make much sense for you, but we did that as a work around for a very specific situation:

var elSelect = angular.element;
angular.element = function(id) {
        try {
            return elSelect.call(angular, id);
        } catch(err) {
            return $(id);
        }
    };

So this works for version 1.5.0 of angular and angular-mocks when testing, but not for 1.5.1-1.5.7. I don't know if it is this specific case or if other cases using angular.element could also break.

[gkalpak]

Thx @vitorarins. As mentioned before, it is a very "naughty" thing to overwrite such a certal component as angular.element and not at least preserve it's properties. Using the angular.extend() technique described above, you would be good though.

var ngElement = angular.element;
angular.element = angular.extend(function(id) {
  try {
    return ngElement.call(angular, id);
  } catch(err) {
    return $(id);
  }
}, ngElement);

Updated plnkr

[vitorarins]

Thank you very much @gkalpak! I hope that at least this serves as reference for other people having this problem. Again Thx a lot!

[lathaMaramganti]

Hi, I am also facing the same issue. But using angular select. In my controller I am initialising select like this.
angular.element('select').select2();

Added spy on as follows :
var ngElement = angular.element('select');
angular.element = angular.extend(function(id) {
try {
return ngElement.call(angular, id);
} catch(err) {
return $(id);
}
}, ngElement);

spyOn(ngElement, 'select2').and.callFake(function() {

    });

PhantomJS 2.1.1 (Mac OS X 0.0.0) ERROR

I had gone through this post fully and used angular 1.5.7 and jasmine 2.4.1. But still issue is not solved.

[mgol]

@lathaMaramganti It's not:

var ngElement = angular.element('select');

but:

var ngElement = angular.element;

You need to save the original function to extend it, not its invocation.
