Detox tests run so slow that element.tap() interpreted as a longPress()

[OlivierFreyssinet-old]

Description

Detox tests run very slowly on android emulator and it causes element.tap() to be interpreted as a longPress().

Because of this, a part of my tests can't pass even if manually, the same behavior works perfectly.
I'm running the tests on a production build, and the app itself is not that slow, at all.

To give you an idea of how slow it is: for instance, swiping in a ViewPagerAndroid takes up to 8s with Detox tests (it runs at like ~1fps) while it is perfectly smooth doing it manually.

I could change the delayLongPress to more than 3000ms but if I could avoid to do that just for the tests, it would be great.

Steps to Reproduce

It's quite simple actually
React native code:

<TouchableOpacity
    onPress={this.onPress().bind(this)}
    onLongPress={this.onLongPress.bind(this)}
    testID="123456789_PersonRow"
>

Detox code:

it('should have personRow for 123456789', async () => {
    await expect(element(by.id('123456789_PersonRow'))).toBeVisible();
})
it('should tap personRow for 123456789', async () => {
    await element(by.id('123456789_PersonRow')).tap();
})

Ok so quick update: I do no longer have this problem after removing one particular looped animation (a blinker).
