matham: I wonder if `has_animation_properties` is a better name? And maybe it's better if its a `@property`?
matham: Oh, Never mind, the function already exists in master. I'll let someone with animation usage review it.
gottadiveintopython: yep it override `Animation.have_prop...()`
Thanks for the review.
tshirtman: I meant for the Sequence and Parallel to have a common method, (but i'm not sure which meaning of "like" you used here, if you meant "in the same way as", then ok). i.e:

```
class CompoundAnimation(Animation):
    def have_property_to_animate(self, widget):
        …

class Sequence(CompoundAnimation):
    …

class Parallel(CompoundAnimation):
    …
```

i think is slightly better than having the exact same method in two classes.
gottadiveintopython: ah I understand what you mean.

`stop()`, `stop_property()`, `cancel()`, `have_properties_to_animate()` are completely same. So moving them to `CompoundAnimation`, the base class. I feel that doing that loose some flexibility. But anyawys I'm doing that now.
gottadiveintopython: `Sequence` and `Parallel` are really buggy while `Animation` is not.
If I continue fixing thoe bugs, this PR will become not related to the issue(#5443).
So I'm probably going to make another PR since the issue is fixed.
tshirtman: Yes, there are certainly bugs left in them, thank you for looking into it.
gottadiveintopython: np :)
well I updated the PR. Can you review it?
gottadiveintopython: thanks
gottadiveintopython: When I ran [this code](https://gist.github.com/gottadiveintopython/ac5e4e1a33a93c31bc53d6875e2b035c) on master branch, `Parallel`s were never released. I assume that's the reason why `Parallel` doesn't override `cancel_property()`. That means I should revert 3608092fcefb6ce949a5ae92a6c347569b95f7f8.
gottadiveintopython: This PR contains this hackey code:

```python
old_max_fps = None


def setUpModule():
    global old_max_fps
    old_max_fps = Clock._max_fps
    Clock._max_fps = 0.0


def tearDownModule():
    global old_max_fps
    Clock._max_fps = old_max_fps
```

Does anyone know proper way of changing `maxfps` temporarily?
gottadiveintopython: ok I'll make this PR more simple.
um should I reset commits? I mean `git reset --hard/soft xxxx`.
Since you already spent a time on reading this PR, I better keep current commits?
tshirtman: It's ok to leave the commits, we can always squash & merge in the interface, if we decide the history is not important in the end. Thank you, just let us know when you are happy about the state, so i can review again :).
gottadiveintopython: ok I got it.
I might reset commits to make this pr easier to understand though.
gottadiveintopython: This should be ok. Can you review it?

>  it also contains tests that are expected to fail, with comments about things that are currently unclear, so i'm not sure what to make of it

sorry for that unreadable test code.
I created simple code: [this](https://gist.github.com/gottadiveintopython/cc23a1ecaa6aa5ffd8a2f60445478eaf) and [this](https://gist.github.com/gottadiveintopython/7605ac5e2d0eaebbc68f124619717087)
Those are not fixed by this PR and I'm not even sure that those should be fixed or not.
tshirtman: Hm, I'm really sorry this lingered for so long, but the code looks good, it does still feel worth merging, especially people still hits the bugs with reusing composed animations from time to time.
tshirtman: Hm, I'm really sorry this lingered for so long, but the code looks good, it does still feel worth merging, especially people still hits the bugs with reusing composed animations from time to time.
gottadiveintopython: @tshirtman Hi, is it better to `git rebase master` and rewrite unit tests in pytest-style? or better to keep the current state?
tshirtman: Hey, if you are willing to, rebasing/updating would be great.
gottadiveintopython: ok, I'll do it then.
gottadiveintopython: `Parallel` never fires `on_progress`, and I think it's corrent behavior. But it might confuse the user, so we may need to document it.
tshirtman: > `Parallel` never fires `on_progress`, and I think it's a corrent behavior. But it might confuse the user, so we may need to document it.
> 
> Or maybe `Parallel` should fire `on_progress` only when `Parallel.anim1` fires `on_progress`.

hm, if we can't then it's better not to document, i don't see how only firing for anim1 would be correct, ideally it would fire for both, and have the progress value take both durations into account (so if anim 1 is 3s and anim 2 is 2s, 1s into the first animation, we'd get progress at 0.2, 1/5th of the total), but i didn't check how hard it would be to implement that.
gottadiveintopython: > we'd get progress at 0.2, 1/5th of the total

Sounds like you are confusing `Sequence` with `Parallel`. But anyways It may be better to keep the current implementation. If we change it to fire `on_progress`, it probably impact the performance, because `on_progress` usually is fired very frequently.

> if we can't then it's better not to document

Ok, got it.

:facepalm: you are right, maybe we could report based on the longest, but yeah, in any case, no need to think about that in this PR, it would be a new feature imho, to be evaluated independently.

:+1: 
gottadiveintopython: `EventCounter.assert_()` is my concern.
gottadiveintopython: @tshirtman 
I believe the PR is mergeable. Could you check if it's ok or not?

> we could report based on the longest

Yeah I agree with that way if we implement it.

kivy.animation.Sequence sends "on_complete" event while animation is still in progress
### Versions

* Python: 2.7
* OS: Linux Ubuntu 16.04
* Kivy: 1.10.1.dev0
* Kivy installation method: git clone and python setup.py install

### Description

The program uses Animation to pulse a Widget color from black to red and back again.  When the animation completes, the Widget is supposed to be black, but it is red.  Could be a canvas update problem, could be an animation bug.
