Step unsuccessful: java.lang.NullPointerException (RuntimeError) #298

Closed angeliaw closed 10 years ago

angeliaw commented 11 years ago

Then I should see "text" while trying to run above sentence in feature, it failed with below exception.

Step unsuccessful: java.lang.NullPointerException (RuntimeError) /Users/.../.rvm/rubies/ruby-1.9.3-p448/lib/ruby/1.9.1/timeout.rb:69:in `timeout'

Calabash-android -v 0.4.11

meredrica commented 11 years ago

Same here. The strange thing is that it sometimes works. Here's what calabash-android console gives:

    irb(main):003:0> performAction('assert_text', 'some_text', true)
    RuntimeError: Step unsuccessful: java.lang.NullPointerException
        from /home/meredrica/.gem/ruby/2.0.0/gems/calabash-android-0.4.14/lib/calabash-android/operations.rb:278:in     `block in perform_action'
        from /usr/lib/ruby/2.0.0/timeout.rb:66:in `timeout'
        from /home/meredrica/.gem/ruby/2.0.0/gems/calabash-android-0.4.14/lib/calabash-android/operations.rb:267:in     `perform_action'
        from /home/meredrica/.gem/ruby/2.0.0/gems/calabash-android-0.4.14/lib/calabash-android/operations.rb:52:in     `performAction'
        from (irb):3
        from /usr/bin/irb:12:in `<main>'
    irb(main):004:0>

the text is absolutely there and I can find it with query

Could you post the relevant stacktrace from logcat?

The screen has an admob view, a map, the actionbar compat and some textviews and imageviews, if that's any useful info. It might be the admob view that's causing problems since the stack looks like robotium tries to look for text in a webview

angeliaw commented 10 years ago

thank you very much. we rolled back to 0.4.6 instead for testing, now it seems to work fine on latest version.

jonasmaturana commented 10 years ago

@angelia Do you mean that the problem is gone in the newer version of Calabash? Which version are you running?

Thanks

This seems like a duplicate of #293, my application has an embedded WebView.

TobiasRoikjer commented 10 years ago

The action assert_text was removed in the latest release of calabash-android. The new ruby wrapper assert_text(text, should_find=true) can be used as a direct alternative and it should not cause a NPE. The document migrating to calabash-android 0.5 contains more information about the removed actions.
