葫芦/红宝石while循环未结束

Question

In short i have a custom step definition to scroll down a page of search results until a text string is found.

It's scrolling down and finding the text string

But the while loop is not ending, despite it correctly scrolling down and stopping when the text string is found.

This is obviously causing me no end of but hurt.

Then /^I scroll until I see the "This is a test" text$/ do 
  q = query("android.widget.TextView text:'This is a test'")
  while q.empty?
    scroll("android.view.View id:'search_listView'", :down)
    q = query("android.widget.TextView text:'This is a test'")
  end
end

is the ruby that I've been using.

Answer 1

Which version of Calabash do you use? I have written similiar step definition and it works perfectly for me (Calabash 0.5.1, Ruby 2.1.2).

Here is the code (I think it's more universal and simple):

Then /^I scroll down until I see '(.*?)' text$/ do |text|
  while element_does_not_exist("TextView marked:'#{text}'")
    scroll_down
  end
end

Both element_does_not_exist() and scroll_down are Calabash Ruby API's functions.

Instead scroll_down you can try to use your function to scroll specified ScrollView.

(edit: Sorry, I didn't look at comments ;))

Try This...

def scroll_to_text(text)
  element = "android.widget.TextView text:'#{text}'"
  if !element_exists(element)
    wait_poll(:until_exists => element, :timeout => 60, :screenshot_on_error => true) do
      scroll("android.view.View id:'search_listView'", :down)
    end
  end
end

This method will give you a screenshot and raise an error if it didn't find the text scrolling after 60 seconds. you can modify to use as you wanted. (I just get the code from your post so if something is wrong at the first time try modifying this).
