#wait(opts = {}) ⇒ Object

Check every interval seconds to see if yield doesn’t raise an exception. Give up after timeout seconds.

Wait code from the selenium Ruby gem github.com/SeleniumHQ/selenium/blob/cf501dda3f0ed12233de51ce8170c0e8090f0c20/rb/lib/selenium/webdriver/common/wait.rb

If only a number is provided then it’s treated as the timeout value.

Examples:


wait(timeout: 20, interval: 0.2, message: 'custom message') { button_exact('Back') }.click
wait(20) { button_exact('Back') }.click

Parameters:

  • opts (Hash|Numeric) (defaults to: {}) —

    Options. If the value is Numeric, the value is set as ‘{ timeout: value }`

Options Hash (opts):

  • :timeout (Numeric) —

    Seconds to wait before timing out. Set default by ‘appium_wait_timeout` (30).

  • :interval (Numeric) —

    Seconds to sleep between polls. Set default by ‘appium_wait_interval` (0.5).

  • :message (String) —

    Exception message if timed out.

  • :ignore (Array, Exception) —

    Exceptions to ignore while polling (default: Exception)
