Configuring Robolectric 2.0

In Robolectric 1.x, it was necessary to extend RobolectricTestRunner if you wanted to configure things differently.

From 2.0 on, most configuration can be accomplished using either the @Config annotation or by adding a special file on your classpath.

You can add the @Config annotation to individual test methods, or entire test classes.

If you'd like to apply a configuration to your entire project, create a file called "org.robolectric.Config.properties", and place it on your classpath. If you're using maven, you could put it in src/test/resources.

Example:

@Config(qualifiers="fr-land")
public void shouldDisplayThingsInFrench() {
  ...
}

Configurable values currently include which manifest to use, the SDK level and qualifiers to report, and the list of additional shadows to enable. See the @Config annotation documentation for details.

Also, remember that Robolectric will now look for a test version of your Application class, where you can do additional configuration which used to require subclassing RobolectricTestRunner.
