Android Cucumber Espresso

#android-cucumber-espresso A template project to demonstrate the usage of Cucumber along with Espresso for acceptance testing on Android.

It was strongly inspired by the official example [1] but with one major difference: Activities could be started with a dedicated step definition. This is important if you want to test multiple activities.

##Introduction This talk [2] provides some basic introduction to the domain. It covers an overview of Cucumber, Gherkin, Features, Steps and Espresso.

##Setup In order to incorporate Cucumber into your test routines a few adoptions has to be performed in your project setup:

• In your build.gradle

• Specify a dedicated test application id (Note: This is mandatory, it won't work otherwise) and a custom CucumberInstrumentationRunner

testApplicationId "com.android.example.test"
testInstrumentationRunner "com.android.example.test.CucumberInstrumentationRunner"

• Add assets to your sourceSets so that Cucumber is able to find your features

 sourceSets {
  androidTest { assets.srcDirs = ['src/androidTest/assets'] }
}

• Add Cucumber dependencies (Note: There is a bug which requires the following declaration)

androidTestCompile('info.cukes:cucumber-android:1.2.4') {
  exclude module: 'cucumber-jvm-deps'
  exclude module: 'guava'
}
androidTestCompile 'info.cukes:cucumber-jvm-deps:1.0.3'
