Description
xcmonkey is a tool for doing stress testing of iOS apps. It's inspired by and has similar goals to monkey on Android.
Under the hood, xcmonkey uses iOS Development Bridge as a driver, that's why it's pretty smart and can do a lot of things, such as taps, swipes and presses. All that comes «pseudo-random» because it has access to the screen hierarchy, and so can either do actions blindly (like tapping on random points) or precisely (like tapping on the existing elements).
Prerequisites
brew install facebook/fb/idb-companion
pip3.6 install fb-idb
Installation
gem install xcmonkey
If you prefer to use bundler, add the following line to your Gemfile
:
gem 'xcmonkey'
Usage
To run a stress test
$ xcmonkey test --event-count 100 --bundle-id "com.apple.Maps" --udid "413EA256-CFFB-4312-94A6-12592BEE4CBA"
12:44:19.343: Device info: {
"name": "iPhone 14 Pro",
"udid": "413EA256-CFFB-4312-94A6-12592BEE4CBA",
"state": "Booted",
"type": "simulator",
"os_version": "iOS 16.2",
"architecture": "x86_64",
"path": "/tmp/idb/413EA256-CFFB-4312-94A6-12592BEE4CBA_companion.sock",
"is_local": true,
"companion": "/tmp/idb/413EA256-CFFB-4312-94A6-12592BEE4CBA_companion.sock"
}
12:44:22.550: App info: {
"bundle_id": "com.apple.Maps",

}
12:44:23.203: Tap: {
"x": 53,
"y": 749
}
12:44:23.511: Swipe (0.5s): {
"x": 196,
"y": 426
} => {
"x": 143,
"y": 447
}
12:44:24.355: Press (1.2s): {
"x": 143,
"y": 323
}
To repeat the stress test from generated session
xcmonkey repeat --session-path "./xcmonkey-session.json"
To describe the required point
xcmonkey describe -x 20 -y 625 --udid "413EA256-CFFB-4312-94A6-12592BEE4CBA"

fastlane integration
To get started with xcmonkey fastlane plugin, add it to your project by running:
fastlane add_plugin xcmonkey
Usage
lane :monkey_test do
bundle_id = 'com.apple.Maps'
device = 'iPhone 14'
sim = FastlaneCore::Simulator.all.filter { |d| d.name == device }.max_by(&:os_version)
udid = sim.udid
xcmonkey(udid: udid, bundle_id: bundle_id)
end
