Xamarin Test Cloud is now part of Visual Studio App Center! Get Started.

Calabash iOS 0.18.1

  • This release requires a server update to 0.18.1.
  • This releases requires at least run-loop 2.0.6.
  • Calabash iOS now requires ruby >= 2.0.

These two wiki pages have instructions for updating the most recent versions.


  • App bundle detection has been improved. It is not clear if the changes will work for all users. @ark-konopacki
  • calabash-ios check correctly detects the Calabash iOS server
  • Calabash::Cucumber::Formatter is now correctly imported

Thanks @ark-konopacki for various fixes and improvements.


Please do not install gems with sudo.

If you are just getting started with Ruby and Calabash on MacOS, we have a new tool: the calabash-sandbox.

For advanced users, we recommend a managed ruby.

If you are not already using bundler and Gemfile, we strongly recommend that you start.

Docs and Examples

For this release, we've updated the README and many of the wiki pages. At the moment the wiki is publicly editiable. If you see a typo or a way to improve the docs, please make the change. If the change is significant, create an issue and we can discuss.

We have also updated the following repositories:

  • LPSimpleExample
    • Getting starting with Calabash
  • iOS Smoke Test App
    • nearly 100% coverage of all the Calabash iOS gestures and behaviors
    • examples of how manage the app life cycle and reset the keychain
    • scripts that demonstrate an efficient Calabash workflow, including how to stage binaries from Xcode builds and how to submit to the Xamarin Test Cloud.
  • iOS WebView App
    • Updated with iframe examples


We've discovered the :preferences is not stable enough to use on Simulators or physical devices. The default will remain :host.

Calabash 2.0

Calabash 2.0 is in pre-release.

Please report issues with Calabash 2.0 as a GitHub issue or on Stack Overflow.

We are looking for help from the community to finish implementing Calabash 2.0. You can see what has to be done in the project GitHub issues.

Xamarin Test Cloud users: Calabash 2.0 is not yet supported on Test Cloud. Test Cloud support will be available before Calabash 2.0 is released.


This is a reminder to check out the Calabash documentation on the Xamarin site. The information there is excellent and constantly improving.
