Don't resolve :(

But, I'm just testing methods in my page and ignore slides in tag....

Thx

The error is coming from here in swiper.js:

/*=========================
  Translate/transition helpers
  ===========================*/
// Cleanup dynamic styles
function cleanupStyles(s) {
    // Container
    removeClass(s.container, s._classNames);
    s.container.removeAttribute('style');

Ahah, there's actually an earlier error:

Uncaught TypeError: this._plt.timeout is not a function

Which is because we don't mock timeout in platformmock

Fixing the above is trivial, but afterwards it seems that initSlides (which creates slides.component) is not called.

Spent ages trying to figure out why the slides weren't being initialised, but it goes back to the first error:

        this._plt.timeout(function () {
            _this._initSlides();
        }, 300);

If we mock out the timeout function to do nothing.. then nothing will happen

We were missing five functions from PlatformMock necessary for the Slides to work. If you update your copy of PlatformMock you should find they will test fine now.

Thx, but this error continues....

HTML:

<div class="colgroup top-space">
    <ion-slides>

      <ion-slide>
        <img src""img>
      </ion-slide>

      <ion-slide>
        <img src""img>
      </ion-slide>

      <ion-slide>
        <img src""img>
      </ion-slide>

    </ion-slides>
  </div>

Plataform mock added 5 functions...

I Tried make this Mock but I don´t know the Slides namespace

export class SwiperMock{ public initSwiper(): void {}; public startAutoplay(): boolean { return true;}; public stopAutoplay(): void {}; public pauseAutoplay(): void {}; public updateAutoHeight(): void {}; public updateContainerSize(): void {}; public updateSlidesSize(): void {}; public currentSlidesPerView(): number {return 1}; public update(): void {}; public fixLoop(): void {}; public slideTo(): boolean {return true}; public onTransitionStart(): void {}; public onTransitionEnd(): void {}; public slideNext(): any { return {}}; public slidePrev(): any { return {}}; public slideReset(): boolean {return true;}; public disableTouchControl(): boolean {return true;}; public enableTouchControl(): boolean {return true;}; public destroySwiper(): void {};

I'm testing a page and facing the same problem 'Error during cleanup of component'. The problem is here components/slides/swiper/swipper.js:

function cleanupStyles (s) {
     s.container.removeAttribute('style');
    // Wrapper
    s._wrapper.removeAttribute('style');
}

this function is called inside another function destroySwiper() but the attributes container and _wrapper are missing so I get a TypeError by calling removeAttribute on undefined :-(
