Use of ABase results in "uninitialized constant Calabash (NameError)"

[Morten Gregersen]

I'm trying to use the ABase class as a base class for my screen objects. I've created my own base class for my screen object which inherits from ABase:

abd_base.rb

require 'calabash-android/abase'

class ABDBase < Calabash::ABase

    #some general stuff for all screens
end

When I run my features I get the folllowing error:

vbus-imac:Calabash bdumgr$ ANDROID_HOME=/Users/bdumgr/Downloads/android-sdk-macosx calabash-android run MyAwesome.apk -v -r android/*

It looks like it doesn't understand "include Calabash::Android::Operations" in "class Calabash::ABase".

Do I need to do anything special to use ABase?

My project structure is as follows:

Calabash

|_android

| |_screens

| | |_menu_screen.rb

| |_support

| | |_//default support files from calabash-android

| |_abd_base.rb

| |_abd_signing_base.rb

|_features

Hi Morten! Have you found any solution? I have the same issue while implementing Page Object Model. Thought it could be a Ruby issue, but updating to 2.2 didn´t work 

[Morten Gregersen]

Hi Kristina

It works for me now. I don't remember doing something special for this to work.

This is most likely an indication that your env does not properly load Calabash-Android. What is the contents of features/support/env.rb ? 

[Kristina Stemikovskaya]

Hi Tobias! 

I found the cause of the error, I forgot to include 

require 'calabash-android/operations'

in features/android/support/env.rb , only had  require 'calabash-cucumber/operations'

Now everything work fine, thanks!
