Overview

A class to manage interactions with CoreSimulators.

Constant Summary collapse

DEFAULT_OPTIONS =

These options control various aspects of an app’s life cycle on the iOS Simulator.

You can override these values if they do not work in your environment.

For cucumber users, the best place to override would be in your features/support/env.rb.

For example:

RunLoop::CoreSimulator::DEFAULT_OPTIONS = 60

{
  # In most cases 30 seconds is a reasonable amount of time to wait for an
  # install.  When testing larger apps, on slow machines, or in CI, this
  # value may need to be higher.  120 is the default for CI.
  :install_app_timeout => RunLoop::Environment.ci? ? 120 : 30,
  :uninstall_app_timeout => RunLoop::Environment.ci? ? 120 : 30,
  :launch_app_timeout => RunLoop::Environment.ci? ? 120 : 30,
  :wait_for_state_timeout => RunLoop::Environment.ci? ? 120 : 30,
  :app_launch_retries => RunLoop::Environment.ci? ? 5 : 3
}

Constructor Details

#initialize(device, app, options = {}) ⇒ CoreSimulator

Returns a new instance of CoreSimulator.

Parameters:

  • device (RunLoop::Device) —

    The device.

  • app (RunLoop::App) —

    The application.

  • options (Hash) (defaults to: {}) —

    Controls the behavior of this class.

Options Hash (options):

  • :quit_sim_on_init (Object) — default: true —

    If true, quit any running

  • :xcode (Object) —

    An instance of Xcode to use simulators in the initialize method.

def app_is_installed?
  !installed_app_bundle_dir.nil?
end

#install ⇒ Object

Install the app.

  1. If the app is not installed, it is installed.

  2. Does nothing, if the app is the same as the one that is installed.

  3. Installs the app if it is different from the installed app.

The app sandbox is not touched.

  installed_app_bundle
end

#launch ⇒ Object

Launch the app on the simulator.

  1. If the app is not installed, it is installed.

  2. If the app is different from the app that is installed, it is installed.
