Assert that element is not visible on the screen

Hi guys, I am having difficulties to assert that certain text is not visible on the screen. I have tried my luck with RSpec Expectations, and different approaches which would be working for web app. However with Appium it does not seem to work.

Here is the link of what I have tried: http://stackoverflow.com/questions/38372530/appium-how-does-one-assert-that-certain-text-is-not-displayed-on-the-screen

There are many examples, how to assert that something IS visible, and that is working as expected. However when its vice versa then it is not going smoothly.

What is your experience in this situation?

Environment

* Mobile app - iOS
* Appium 1.5.2 + Cucumber + WatirWebdriver + Ruby + RSpec Expectations

I’m using Appium Ruby bindings and here is an example what I do in such cases:

[1] pry(main)> wait_true { ignore { text('text that is not visible on screen') }.nil? }
true

Same example with a text that is visible on screen:

[2] pry(main)> wait_true { ignore { text('Media') }.nil? }
Selenium::WebDriver::Error::TimeOutError: timed out after 30 seconds

No problem - hope this brief explanation helps.

wait_true { ignore { text('text that is not visible on screen') }.nil? }

wait_true, ignore and text are Appium Ruby binding methods and can be found from project: https://github.com/appium/ruby_lib

text will return the first “textfield” element with given text. Since such element is not going to be found it will throw an exception. We will catch exception with ignore block. When text is not found ignore block will return nil. Finally we use wait_true block to poll that return value is nil meaning text is not visible on the screen.
