Error while trying to tap.

Hi There,

I am getting below error while I tried to use the API on Andorid phone thru Appium on Mac box.

I recently used this gem (for Android Chrome browser) after reading an appium issue. https://github.com/appium/appium/issues/3896

Also encountered the 'script' must be a string error. Here's the error in IRB console:

I'm traveling right now so I can't take a closer look, but can you try using Version 1.1.0 or even 1.0.0 and see if the error persists? I might know why this is happening. Let me know if either worked or not please.

It's working with touch_action -v 1.1.0. The element was tapped and page responded.

Tried other gestures as well, doubletap worked.

I'm aware that the filed issue relates to 'TAP', but other gestures seems to be not working. i.e. swipe down using element.touch_action(:flick, axis: 'y', distance: 100, duration: 60) did not do anything against the mobile web page. (http://coenraets.org/apps/angular-directory/#/employees)

element = driver.find_element(:xpath, '//html/body/div/div[3]/ul/li[1]/a') => # element.touch_action(:flick, axis: 'y', distance: 500, duration: 60) => nil Am I missing something in this :flick action?

I was able to go to the bottom of the page using: driver.execute_script("arguments[0].scrollIntoView(true);", element_at_the_bottom_of_the_page)

[Ricardonacif]

The flick action won't work as a mobile scroller. It will only work for swiping elements that are specifically listening for touch events. Like this one: http://hammerjs.github.io/

[blago]

Makes sense. Thanks for explaining that.

Tried the available touch_action gestures against this element on that page. element = driver.find_element(:id, 'hitarea')

They all worked with -v 1.1.0 on Android's Chrome browser.

[Ricardonacif]

Awesome, I think I'll rollback the to that version. I did somethings on the code in a hurry to accomplish one other thing, and looks like I messed up.

[Ricardonacif]

Rolledback the code (use 1.3.0). @PushkarPahare can you update the gem now to 1.3.0 and see if it is working?

[Ricardonacif]

@PushkarPahare did it work?
