Resuming an app

[Mark Reid]

Is that possible to write a test that resumes an app that has been put into the background?

[Jani Jegoroff]

Yes, you can use adb command for that.

# send to background

adb shell input keyevent 3

# bring to foreground

adb shell am start -n <PACKAGE-NAME>/<PATH-TO-ACTIVITY>

Check your <PACKAGE-NAME> and <PATH-TO-ACTIVITY> from source code AndroidManifest.xml

[Paul Lonean]

First of all Thanks Jani for the help, but I have a question:

After I use:

And I wait for 2 seconds

And I tap the Home button (using: adb shell input keyevent 3 )

        And I resume the app (using: adb shell am start -n <PACKAGE-NAME>/<PATH-TO-ACTIVITY>)

And I enter "plonean" into input field number 1

The following scenario happened to me. The app opens, and i wait for 2 seconds (as my first step says), but after the app is in background since I tapped the Home button from the step 2, the 3rd step isn't starting. The calabash test's aren't working anymore and the strange thing is that no error were shown in the console. Do you have any ideas how to solve this?

Thanks!

[Paul Lonean]

As a update:

Initially I used:

Given /^I resume the app$/ do 

%x(adb shell am start -n com.voalte.voalteone/.activity.MainVoalteOneActivity)

end

And after some researches I understood that i should use:

Given /^I resume the app$/ do 

system('adb shell am start -n com.voalte.voalteone/.activity.MainVoalteOneActivity &')

end.

But now the problem is that after the resume is made this error is displayed in the cmd console:

    And I enter "test" into input field number 2 # calabash-android-0.5.5/lib/ca

Have you made sure that your commands works from Calabash console?

I just implemented example scenario using my application and it works fine.

Given application is launched

When I send application to background

Then application is sent to background

When I bring application to foreground

Then application is bring to foreground

And Home screen is displayed

1 scenario (1 passed)

6 steps (6 passed)

0m34.126s

Here are example background/foreground step definition implementations:

def when_send_app_to_background

  ADB.send_to_background

end

def when_bring_app_to_foreground

  ADB.bring_to_foreground('APP-PACKAGE-NAME', 'PATH-TO-ACTIVITY')

end

  

def then_app_in_background

  wait_for { app_in_background? }

end

def then_app_in_foreground

  wait_for { !app_in_background? }

end

def app_in_background?

  currentApp = `adb shell dumpsys window windows | grep -E 'mCurrentFocus'`

  !currentApp.include?('APP-PACKAGE-NAME')

end

ADB methods are implemented in my RubyGem. See https://rubygems.org/gems/android-adb-extension

[Paul Lonean]

Thanks a lot so far, but I have a question: Where should I define those adb commands? Not in calabash_steps.rb file? And if they should be defined there should I just copy paste your code written bellow and it should work?

 

Thanks

You can define methods where ever you want, depends how you have structured your code. But I would not use calabash_steps.rb.

Just call those methods from your step definitions.

[Paul Lonean]

Sorry for bothering you so much but it simply just don’t workL.

 

In another rb file I’ve defined my adb commands like this:

 

def when_send_app_to_background

  ADB.send_to_background

end

def when_bring_app_to_foreground

  ADB.bring_to_foreground('com.voalte.voalteone/.activity.MainVoalteOneActivity')

end

 

def then_app_in_background

  wait_for { app_in_background? }

end

def then_app_in_foreground

  wait_for { !app_in_background? }

end

def app_in_background?

  currentApp = `adb shell dumpsys window windows | grep -E 'mCurrentFocus'`

  !currentApp.include?('APP-PACKAGE-NAME')

end

 

 

After that in the calabash-steps.rb file I’ve defined:

 

Given /^I send app$/ do

                when_send_app_to_background

end

 

Andafter all those things I’e tried to run the Script my_first_feature.feature which contains:

Feature: Successfully Log In

 

                Scenario: Log in

                And I wait for 2 seconds

                Given I send app (the defined step)

 

And I receive in the cmd console the following error message, note that the app and scripts didn’t even start:

 

  undefined method `last' for #<Enumerator:0x2e6bc00> (NoMethodError)

Sorry again, but do you think that you can give me your skype id? It would be much easier to talk and end this.

 

Thanks.

Sure, no problem. Skype id is firstName.LastName

I’ve added you on skype, but for any edge case my Skype id is en_plonean
