Calabash Launcher

Calabash Launcher is a macOS app that helps you run and manage Calabash iOS tests on your Mac.

  • Instead of having to run and configure test runs in console, you can use a simple user interface which helps you to pick up needed devices, languages, tags, builds and other parameters.
  • Instead of having to search elements by quering view hierarchy again and again, you can click on the element under search and get its class name, accessibility label and/or accessibility id.

Test Runner

The Test Runner runs tests on a variety of configurations. It supports:

  • Running tests on a simulator
  • Running tests on a physical device
  • Running tests in different languages
  • Test tags
  • Console output

Element Inspector

With the Element Inspector you can inspect your apps view hierarchy to get elements query strings in hierarchy tree representation.

It supports:

  • Device element highlighting
  • Accessing an element's address
  • Accessing an element's localized object (by reading all .strings and .json files in the project)
  • The visual representation of the device

Project Status

This project is under active development, and it is heavily used at XING SE.


In order to run the application you have to make sure that your machine meets the following requirements.

  • MacOS Sierra or newer
  • Xcode 9.0 or newer
  • iOS Simulators >= 10.1
  • Ruby >= 2.2.0 (2.3.1 is preferred)
  • bundler >= 1.15.0
  • calabash-ios >= 0.20.5

Xcode Configuration

After you have cloned the project to your mac, open the project in Xcode. Before you start to build the project you need to add a developer team to the project. Use your Apple ID to sign in and to create a personal team.

XCode - Adding a developer team

Once the team is added, hit the build button and the calabash launcher will start in a few seconds.

Using the Test Runner

When opening Calabash Launcher the first time, it will ask you to give the path to the repository with your Calabash tests and (optionally) your Cucumber profile.

Calabash Launcher Setup

Provide the required data and press save. After a restart of the Calabash Launcher, you will be able to configure your testrun by choosing a simulator, the language and the Cucumber tag to execute.

Test Runner

Running on physical devices

To run tests on physical devices, the device's IP and app's bundle ID should be provided in the device configuration dialog:

Using the Element Inspector

⚠️ Currently the Element Inspector is limited to iPhone 6, iPhone 7 and iPhone 8. Please make sure that one of these devices is launched when you search for elements. ⚠️

Element Inspector

  • Clicking on the right window in the view will sync the Inspector with the simulator (and it will be automatically synced every 5 seconds)
  • Clicking on an element in the synchronised window will show the element's class, accessibility id and accessibility label.
  • Clicking on a nested menu of an element will show you the element hierarchy.


  • Calabash Launcher will not work if you cannot run bundle exec calabash-ios console from your terminal. Sometimes the problem could live in the Ruby installation and/or conflicts with readline. To fix the problem, please re-install Ruby.
  • You can reset Calabash Launcher's settings via the Reset to Defaults Settings menu item.
