Running Xcode UI Tests from Linux, using Docker
This document describes how to run Xcode UI Tests, such as the Facebook WebDriverAgent (or the Appium fork),
xcuitrunner command-line utility, running in a Docker container on Linux.
This setup consists of two Docker containers:
usbmuxd, the USB multiplexer for iOS devices.
usbmuxdallows Linux programs to communicate with iOS devices. It acts as a daemon.
usbmuxdruns in a background container.
xcuitrunner, the command-line utility that launches the Xcode UI Test. If you want to run multiple Xcode UI Tests in parallel, you can run start multiple containers running
This document describes how to run the
xcuitrunner on CentOS Linux using Docker. Instructions for other Linux distributions
You need to install Docker before you can run Docker containers. You can use the Community Edition, Docker CE.
Install the required packages
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
Add the Docker repository
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install docker-ce docker-ce-cli containerd.io
sudo systemctl start docker
Run the following commands to download and launch the
usbmuxd Docker image. This command
launches a background Docker container running
usbmuxd, which automatically starts
when the system reboots.
sudo docker run \ --privileged \ -v /dev/bus/usb:/dev/bus/usb \ -v /var/lib/lockdown:/var/lib/lockdown \ -v /var/run:/var/run \ --name usbmuxd \ --restart always \ quamotion/usbmuxd \ usbmuxd -f -v
To check whether the Docker container is running, you can run:
sudo docker ps
To test the connectivity with your iPhone, connect your iPhone using an USB cable. You should see a Trust pop up on the device. Trust the computer.
Then, open a Bash shell inside the usbmuxd Docker container:
sudo docker exec -it usbmuxd /bin/bash
You can now run various commands, such as
idevice_id -l to list all iOS devices, or
idevicesyslog to show the system logs.
To exit the Bash shell inside your
usbmuxd container, simply type
You need to share some files between your host (the computer on which you run Docker) and the container (which is running
xcuitrunner). This includes your Quamotion license file, the Developer Disk images, and your developer profile.
sudo docker run quamotion/xcuitrunner.
Store these files in
/var/lib/xcuitrunner, and then make that folder available inside your container by
mounting it as a volume.
Use the following command to launch the xcuitrunner:
sudo docker run \ -it \ --net host \ -v /var/run:/var/run \ -v /var/lib/xcuitrunner:/var/lib/xcuitrunner \ quamotion/xcuitrunner \ /app/xcuitrunner \ run \ -l /var/lib/xcuitrunner/.license \ -d /var/lib/xcuitrunner/quamotion.developerprofile \ -p [PASSWORD] \
