Calabash-Android

Calabash-Android lets you run Cucumber features on your Android device or emulator. A Cucumber feature could look something like this:

Feature: Login feature
  Scenario: As a valid user I can log into my app
    Given I am a valid user
    And I enter my username
    And I enter my password
    And I press "Login"
    Then I see "Welcome to coolest app ever"

You can run your Calabash features on multiple devices using LessPainful.com.

Installation

Prerequisites

You need to have Ruby installed. Verify your installation by running ruby -v in a terminal - it should print "ruby 1.8.7" (or higher)

You should have the Android SDK installed and the environment variable ANDROID_HOME should be pointing to it.

Installation

Install calabash-android by running

  • gem install calabash-android
  • You might have to run sudo gem install calabash-android if you do not have the right permissions.

Configuration

To configure calabash run calabash-android setup in the folder you want to use for your Calabash project. You will be asked a series of questions about your app and environment. Here is an example (without any answers):

When you are through this setup your settings will be saved to .calabash_settings. You can edit this file if you have the need.
What is the package name of the app? You can find the package name in AndroidManifest.xml

What is the fully qualified name of the main activity?

What is the path to the app?

Which api level do you want to use?
It looks like you have the following versions installed:
4, 7, 8, 10, 15

Do you want to specify a keystore for signing the test app?
If now we will be using /Users/jml/.android/debug.keystore
Please answer yes (y) or no (n)
y
Please enter keystore location
 
Please enter the password for the keystore

Please enter the alias

Please enter the password for the alias

Saved your settings to .calabash_settings. You can edit the settings manually or run this setup script again

You can always run calabash-android setup again or change the file manually.

Notice: Make sure that the app you are trying to test is signed with the key store you just selected in the setup.

Generate a Cucumber skeleton

To get started with calabash it might be a good idea to run calabash-android gen. It will create a Cucumber skeleton in the current folder like this:

features
|_support
| |_app_installation_hooks.rb
| |_app_life_cycle_hooks.rb
| |_env.rb
| |_hooks.rb
|_step_definitions
| |_calabash_steps.rb
|_my_first.feature

In this skeleton you find all the predefined steps that comes with calabash. Try to take a look my_first.feature and change it to fit your app.

Writing a test

The Cucumber features goes in the features library and should have the ".feature" extension.

You can start out by looking at features/test_dummy.feature. You can extend this feature or make your own using some of the predefined steps that comes with Calabash.

Running test

To run your test:

calabash-android run

If you run the test for the first time you have to build the test server before running the test (see below). calabash-android run will run calabash-android build if it cannot find a test server.

Building the test server

Calabash will install an instrumentation along with your app on the device to run the test. Because of some app specific information we need to build the test server based on the input you provided during setup. Please note that you need to rebuild the test server every time you change the app.

You build the test server like this:

calabash-android build

Predefined steps

The predefined steps are located in the features/step_definitions folder. A compiled list of predefined steps with comments is available here
