Welcome to Calabash for iOS

Calabash is an automated testing technology for Android and iOS native and hybrid applications. This repository contains support for iOS, for Android, see Calabash Android.

This document explains how to install Calabash. For introductory information about the rationale behind Calabash see

Introducing Calabash.

This guide explains how to setup and use Calabash for iOS

After completing this guide you will be able to run tests locally against the iOS Simulator. You can also interactively explore and interact with your application using the Calabash console.

Finally, you will be able to test your app on real, non-jailbroken iOS devices via the LessPainful service.

This guide was writting using XCode 4.2, but should also work for XCode versions >= 4.0.

NOTE about Xcode 4.3 after upgrading to Xcode 4.3, I needed to install the command line tools from the preferences pane under "Downloads" in Xcode. Then I had to do

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

Installation

Prerequisites

You need to have Ruby installed. This is installed by default on MacOSX. Verify by running ruby -v in a terminal - it should print "ruby 1.8.7" (or higher).

Fast track

Note: Fast track installation works for most iOS projects, but there are some project setups where it does not. If it doesn't work in your project, you should read the section "Manual setup with Xcode" below.

Note: If you are an existing user of Calabash iOS, don't run setup. Instead you can update to the latest version by running. gem update calabash-cucumber (or possibly sudo gem update calabash-cucumber) and from your project directory (containing calabash.framework) run calabash-ios download.

Otherwise, follow these steps:

In a terminal, go to your iOS project

cd path-to-my-ios-project (i.e. directory containing .xcodeproj file)

Install calabash-cucumber gem (this make take some time because of dependencies)

gem install calabash-cucumber
(Note you may need to run sudo gem install calabash-cucumber if you get ERROR: While executing gem ... (Gem::FilePermissionError)).

Setup your project for Calabash-iOS.

calabash-ios setup (Answer the questions and read the output :)

Generate a skeleton features folder for your tests

calabash-ios gen

In Xcode, build your project using the -cal scheme

Run the generated test!

cucumber

If all goes well, you are now ready to write your first test. Start by editing the file features/my_first.feature.

Proceed by reading details about installation below, or moving on to the Getting started guide.

Important notice

The Calabash framework uses private Apple APIs to synthesize touch events. This means that you should double check that calabash.framework is not included in the .ipa file you submit to App Store. This is usually done by creating a separate build configuration or target for the version of your app running calabash tests.

Installation details

If fast track setup doesn't work for you, or you're interested in what's going on you can read the installation details here.

Preparing your application.

To use Calabash for iOS in your app, you must do two things: link with our framework: calabash.framework, and install a ruby gem as described below. (You also need to link with Apple's CFNetwork framework if you are not already using this.)

There are two primary ways of linking with the framework. Either you can create a whole separate target by duplicating your production target from Xcode. Alternatively you can create a special build configuration for your existing target. The second option is easiest to maintain and setup, but there are some situations where it cannot be used. Particularly, you must ensure you are not accidentally loading calabash.framework which may happen if you use -all_load or -ObjC linker options. In this case you must make a separate target for calabash (see Manual setup with Xcode below).

Ruby and calabash-cucumber gem.

Make sure ruby and ruby gems is on your path.

krukow:~/examples$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.1.0]
krukow:~/examples$ gem -v
1.8.10

Install the calabash-cucumber gem.

krukow:~$ gem install calabash-cucumber
Successfully installed calabash-cucumber-0.9.23
1 gem installed
Installing ri documentation for calabash-cucumber-0.9.23...
Installing RDoc documentation for calabash-cucumber-0.9.23...

You now have two options: automated setup using the calabash-ios tool or manual setup. Both are described below.

Automated setup using the calabash-ios tool

Verify that you have installed calabash-cucumber correctly by running calabash-ios from the command line:

krukow:~/tmp/sample$ calabash-ios
Usage: calabash-ios <command-name> [parameters]
<command-name> can be one of
    help
     prints more detailed help information.
    gen
     generate a features folder structure.
    setup (EXPERIMENTAL) [opt path]?
     setup your XCode project for calabash-ios)
  ...

Make sure you are in the directory containing your project. Then run calabash-ios setup and answer any questions it might ask :)

Note that calabash-ios will backup your project file:

krukow:~/tmp/sample$ calabash-ios setup
Checking if Xcode is running...
----------Info----------
Making backup of project file: /Users/krukow/tmp/sample/sample.xcodeproj/project.pbxproj
...

The project file is copied to project.pbxproj.bak. In case something goes wrong you can move this file back to project.pbxproj (in your .xcodeproj) folder.

Setup will modify your xcode project file to use Calabash iOs. You should now have a new Scheme named [target]-cal in Xcode:

calabash-ios setup does the following:

add the calabash.framework to your Frameworks folder
add $(SRCROOT) to framework search path
link with calabash.framework (target can be chosen)
link with Apple's CFNetwork.framework
create a new Build configuration: Calabash
ensure calabash.framework is loaded in Calabash configuration
create a new scheme name -cal. This scheme launches the Calabash configuration for your target

Note that calabash.framework is added to your target, but only forced to load in the Calabash build configuration. Hence it is stripped from your other build configurations. But this stripping only occurs if you don't force the load by other means such as setting Other Linker Flags: -ObjC or -all_load. It is your responsibility to ensure that you are not loading calabash.framework in the app you submit to App Store.

Manual setup with Xcode

Instructions:

Step 1/3: Duplicate target.

Select your project in XCode and select your production target for your app.
Right click (or two-finger tap) your target and select "Duplicate target"
Select "Duplicate only" (not transition to iPad)
Rename your new target from ".. copy" to "..-cal"
From the menu select Edit Scheme and select manage schemes.
Rename the new scheme from ".. copy" to "..-cal"

Step 2/3: Link with framework.

Download the latest version of calabash-ios at https://github.com/calabash/calabash-ios/downloads.
Unzip the file.
Use Finder to open the folder that contains calabash.framework.
Drag calabash.framework from Finder into you project's Frameworks folder in Xcode. Make sure that (i) Copy items into destination group's folder (if needed) is checked and (ii) only your "-cal " target is checked in Add to targets.
You must also link you -cal target with CFNetwork.framework (unless your production target is already linking with CFNetwork). To do this click on your -cal target in XCode. Click on Build Phases, expand Link Binary with Libraries, click + to add CFNetwork.framework.

Step 3/3: cal-Target Build Settings

Click on your project and select your new "-cal" target.
Select "Build Settings".
Ensure that "All" and not "Basic" settings are selected in "build settings".
Find "Other Linker Flags" (you can type "other link" in the search field).
Ensure that "Other linker flags" contains: -force_load "$(SRCROOT)/calabash.framework/calabash" -lstdc++

Note: Now that you have created a separate target, new files that you add to your project are not automatically added to your -LP target. Make sure that any new files you add to your production target are also added to your -LP target.

This screenshot is a reference for you build settings.

Test that `calabash.framework` is loaded.

Make sure you select your "..-cal" scheme and then run you app on 4.x/5 simulator.

Verify that you see console output like

2012-01-19 LPSimpleExample[4318:11603] Creating the server: <HTTPServer: 0x7958d70>
2012-01-19 LPSimpleExample[4318:11603] HTTPServer: Started HTTP server on port 37265
2012-01-19 LPSimpleExample[4318:13903] Bonjour Service Published: domain(local.) type(_http._tcp.) name(Calabash Server)

You should now be able to explore Calabash.
