Fix performance issues caused by 8d15a25dcbb23 The earlier commit would maintain a static list of styles, and every time a style resource was added to a theme, it would stay there until the end of time (or termination of JVM). When executing thousands of tests, this would lead to massive slowdown of test execution - over 2x increase in our company's case. Now, the duplicate styles are removed and the new one is added, which keeps the list short and performance reasonable. Change-Id: Ib7ed9321c31938577c78aab52a1d8380bf1be4e6
Robolectric is a testing framework that de-fangs the Android SDK so you can test-drive the development of your Android app.
Here's an example of a simple test written using Robolectric:
@RunWith(RobolectricTestRunner.class) public class MyActivityTest { @Test public void clickingButton_shouldChangeResultsViewText() throws Exception { Activity activity = Robolectric.setupActivity(MyActivity.class); Button pressMeButton = (Button) activity.findViewById(R.id.press_me_button); TextView results = (TextView) activity.findViewById(R.id.results_text_view); pressMeButton.performClick(); String resultsText = results.getText().toString(); assertThat(resultsText, equalTo("Testing Android Rocks!")); } }
For more information about how to install and use Robolectric on your project, extend its functionality, and join the community of contributors, please visit http://robolectric.org.
If you'd like to start a new project with Robolectric you can use deckard (for either maven or gradle). These project will guide you through setting up both Android and Robolectric on your machine.
testCompile "org.robolectric:robolectric:2.4"
<dependency> <groupId>org.robolectric</groupId> <artifactId>robolectric</artifactId> <version>2.4</version> <scope>test</scope> </dependency>
Robolectric requires the Google APIs for Android (specifically, the maps JAR) and Android support-v4 library. To download this onto your development machine use the Android SDK tools and then run the following to install them to your local Maven repository (you will need to have the ‘Android Support Repository’ installed):
mvn install:install-file -DgroupId=com.google.android.maps \ -DartifactId=maps \ -Dversion=18_r3 \ -Dpackaging=jar \ -Dfile="$ANDROID_HOME/add-ons/addon-google_apis-google-18/libs/maps.jar" mvn install:install-file -DgroupId=com.android.support \ -DartifactId=support-v4 \ -Dversion=19.0.1 \ -Dpackaging=jar \ -Dfile="$ANDROID_HOME/extras/android/m2repository/com/android/support/support-v4/19.0.1/support-v4-19.0.1.jar"
You will need to either replace or have ANDROID_HOME
set to your local Android SDK for Maven to be able to install the jar.
Robolectric is built using Maven. Both Eclipse (with the M2Eclipse plug-in) and IntelliJ can import the pom.xml
file and will automatically generate their project files from it.
Guides on to extending Robolectric can be found here and the contributor guidlines can be found here.
If you would like to live on the bleeding edge, you can try running against a snapshot build. Keep in mind that snapshots represent the most recent changes on master and may contain bugs.
