https://github.com/cucumber/cucumber/wiki/Hooks#tagged-hooks
UPDATED for Calabash 0.17 and run-loop 2.0.2
This project contains an example of how to use Cucumber tags and Before hooks to re-install apps and clear application data on simulators and devices.
https://github.com/calabash/ios-smoke-test-app/
In particular, see these two files:
ideviceinstaller wrapper
support/01_launch.rb
I won't reproduce the entire 01_launch.rb example here, but here are the hooks:
Before("#no_relaunch") do
#no_relaunch = true
end
Before('#reset_app_btw_scenarios') do
if xamarin_test_cloud? || LaunchControl.target_is_simulator?
ENV['RESET_BETWEEN_SCENARIOS'] = '1'
else
LaunchControl.install_on_physical_device
end
end
Before('#reset_device_settings') do
if xamarin_test_cloud?
ENV['RESET_BETWEEN_SCENARIOS'] = '1'
elsif LaunchControl.target_is_simulator?
target = LaunchControl.target
instruments = RunLoop::Instruments.new
xcode = instruments.xcode
device = instruments.simulators.find do |sim|
sim.udid == target || sim.instruments_identifier(xcode) == target
end
RunLoop::CoreSimulator.erase(device)
else
LaunchControl.install_on_physical_device
end
end
Before do |scenario|
launcher = LaunchControl.launcher
options = {
#:uia_strategy => :host
#:uia_strategy => :shared_element
:uia_strategy => :preferences
}
relaunch = true
if #no_relaunch
begin
launcher.ping_app
attach_options = options.dup
attach_options[:timeout] = 1
launcher.attach(attach_options)
relaunch = launcher.device == nil
rescue => e
RunLoop.log_info2("Tag says: don't relaunch, but cannot attach to the app.")
RunLoop.log_info2("#{e.class}: #{e.message}")
RunLoop.log_info2("The app probably needs to be launched!")
end
end
if relaunch
launcher.relaunch(options)
launcher.calabash_notify(self)
end
ENV['RESET_BETWEEN_SCENARIOS'] = '0'
# Re-installing the app on a device does not clear the Keychain settings,
# so we must clear them manually.
if scenario.source_tag_names.include?('#reset_device_settings')
if xamarin_test_cloud? || LaunchControl.target_is_physical_device?
keychain_clear
end
end
end
The key is recognize the difference between testing on simulators and devices and testing on the Test Cloud and locally.
You can reset the application settings and content before every Scenario using the RESET_BETWEEN_SCENARIOS env variable.
$ RESET_BETWEEN_SCENARIOS=1 cucumber
You can also implement a backdoor method to reset your app to a good known state. This example is a bit wonky and out of date, but I have used it to great effect in the past - it really speeds up tests - briar-ios-example You can do all kinds of things with backdoors: log users in/out, reset databases, wipe user preferences, add/remove files from the sandbox.
