Ruby Appium::TouchAction .perform returns error - Method has not yet been implemented

[mark0203]

I’m quiet new to Appium so maybe this is really simple to answer, but I just don’t know what to do next.

Setup:
Appium server 1.6.5
Ruby 2.3.3 (32 bit)
Android Phone (Nexus 5) connected via usb
gems:

• appium_lib 9.5.0 & 9.6.0
• selenium-webdriver 3.5.1

Script

require 'appium_lib'
capabilities = {
    deviceName:        'Nexus5',
    browserName:	   'chrome',
    platformName:      :android,
    newCommandTimeout: 15000,
}
appium = Appium::Driver.new(caps: capabilities)
driver = appium.start_driver
driver.get("https://www.google.nl")

Action I want to perform
Now I want to tap/press on any location on the screen (preferably on a certain element, but let’s take smaller steps)

I tried, but I get the error

irb(main):014:0> appium.tap(x:900, y:670).perform

I did read about similar issues, like TouchAction().perform() - Method has not yet been implemented
But that did not give me enough information to understand what I’m doing wrong. It must be something small since I see examples that work. If someone could point me to information to understand the issue that would also be helpful.

I read some people mentioning in the Java examles to use the Android driver.
But when I was reading this document I think I already do that with the platformName :android capability.
Also when I read this documentation about the appium_lib I used the exact copy of that code to start the driver (so far so good) but again when performing a tap I get the same error message as the one I just have with my example.
http://www.rubydoc.info/github/appium/ruby_lib/Appium/Driver

So I’m clueless about what is going wrong. Is it my setup or is it a bug?

@mark0203 same examples in case:

1. https://github.com/appium/ruby_lib/blob/master/android_tests/lib/android/specs/common/device_touchaction.rb
2. https://github.com/appium/ruby_lib/blob/master/android_tests/lib/android/specs/common/web_context.rb

How about press, release and perform mentioned the above comment?
I guess if press and release work well, tap command’s count parameter is wrong for current spec. (the tap method hasn’t been changed for three years.

[mark0203]

I forgot to mention I also tried press. Results are the same as tap.
Here I use the example where I press on a certain element

irb(main):045:0>   e =driver.find_element(:id, 'lst-ib')
=> #<Selenium::WebDriver::Element:0x..f926f926a id="0.9853208960371109-1">
irb(main):046:0>   touch_action = Appium::TouchAction.new.press(element: e, x: 0.5, y: 0.5).release(element: e)

I did read something about not needing to switch context when you test a website (because it’s not a app native/hybrid, but always a webview). If that is not the case let me know how to do this.
I tried the examples, but I’m not 100% sure how to use this (see below)

irb(main):050:0> browser.contexts = available_contexts
NameError: undefined local variable or method `available_contexts' for main:Object
        from (irb):50
        from C:/Ruby23/bin/irb.cmd:19:in `<main>'

        from (irb):51
        from C:/Ruby23/bin/irb.cmd:19:in `<main>'
irb(main):052:0>
irb(main):053:0> contexts = Appium::Device.available_contexts

I’ve confirmed the behaviour in https://github.com/appium/ruby_lib/pull/646/files and tap works well for NATIVE_APP. If webview context, current behaviour is expected: https://github.com/appium/appium/issues/9040 . You can find Touch Actions and Mobile Web for web context.

For available_contexts, I guess you should call driver.available_contexts. Could you try to driver.available_contexts after driver = appium.start_driver?
@mark0203

[mark0203]

@KazuCocoa thnx, that was the mistake I made, wrong object.

irb(main):010:0> contexts = driver.available_contexts
=> ["NATIVE_APP", "CHROMIUM"]

So now it seems to work like this

appium = Appium::Driver.new(caps: capabilities)
driver = appium.start_driver

contexts = driver.available_contexts
=> ["NATIVE_APP", "CHROMIUM"]
current_context = driver.current_context
=> "CHROMIUM"

webview_context = contexts.detect { |e| e.start_with?('WEBVIEW') }
=> nil
nativeview_context = contexts.detect { |e| e.start_with?('NATIVE_APP') }
=> "NATIVE_APP"
chromiumview_context = contexts.detect { |e| e.start_with?('CHROMIUM') }
=> "CHROMIUM"
driver.get("https://www.google.nl")

driver.set_context nativeview_context

elm = driver.find_element(:id, 'lst-ib')

tap_action = Appium::TouchAction.new.tap(element: e, x:0.5, y:0.5)
tap_action.perform

Many thanks, this was what I was looking for.
