Spock for Android
This library allows for the Spock Framework mocks to be used on Android. As well as add some helpful features to make Android testing easier.
Usage
Setup Groovy For Android
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.2'
classpath 'org.codehaus.groovy:groovy-android-gradle-plugin:1.2.0'
}
}
apply plugin: 'com.android.application' apply plugin: 'groovyx.android'See groovy-android-gradle-plugin for more information on setting this plugin up.
Setup Dependencies
dependencies {
...
androidTestCompile "com.andrewreitz:spock-android:2.0"
...
}
Setup Android Plugin
android {
...
defaultConfig {
...
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
packagingOptions {
exclude 'META-INF/LICENSE'
}
}
Write your tests
Tests must be placed in the ./src/androidTest/groovy directory.
Write your tests like you would regular spock tests. See the spock-android-sample project and Spock Framework for more details.
Mocking
Objenesis and cglib do not work with Android. But that’s okay, using dexmaker we can still create mock objects in spock fashion. The only difference is instead of your test classes inheriting from Specification, you need to inherit from AndroidSpecification.
Note: You can not use mocked automatic getters and setters. Example mocked.getName() will work where as mocked.name will not. This is due to limitations of Android not having the java.bean package available.
Annotations
UseActivity is an field annotation to get access to your Activity during tests. You can even provide bundle arguments by supplying a BundleCreator.
Ex.
@UseActivity(MyActivity) def myActivityUseApplication is a field annotation that supplies your Application.
Ex.
@UseApplication(MyApplication) def myApplicationWithContext is a field annotation that supplies you with a context. This is not an implementation of your application.
Ex.
@WithContext def contextAll field annotations will be set during the setup fixture.
Other Notes
-
Android Studio can not run tests with spaces in the name. This is due to a limitation with how it tells the Android device how to run them. To get around this you can name tests without spaces. EX: "this_is_my_test" or just run them in gradle with
gradle connectedAndroidTest. -
Spock includes some references to Java packages that are not included in Android. You may need to use
lintOptions { disable 'InvalidPackage' }to avoid lint failures.
