Fix ShadowAccessibilityManager to keep static instance

1) Shadows.shadowOf(mAccessibilityManager).setEnabled(true)
2) AccessibilityManager.getInstance(mContext).isEnabled()

Calling 1) does not make 2) return true, and 2) is the common pattern
that can be found in the Android framework, so we cannot enable
accessibility in robolectric tests correctly.

The reason is that the current implementation creates new instance
each time, while setEnabled() and other methods only apply to
the current instance. This can be fixed by keeping a static instance, an
approach similar to AccessibilityManager.getInstance().

Build Status

Robolectric is a testing framework that de-fangs the Android SDK so you can test-drive the development of your Android app.

Usage

Here's an example of a simple test written using Robolectric:

@RunWith(RobolectricTestRunner.class)
@Config(constants = BuildConfig.class)
public class MyActivityTest {

  @Test
  public void clickingButton_shouldChangeResultsViewText() throws Exception {
    Activity activity = Robolectric.setupActivity(MyActivity.class);

    Button button = (Button) activity.findViewById(R.id.press_me_button);
    TextView results = (TextView) activity.findViewById(R.id.results_text_view);

    button.performClick();
    assertThat(results.getText().toString(), equalTo("Testing Android Rocks!"));
  }
}

Install

Starting a New Project

If you'd like to start a new project with Robolectric tests you can refer to deckard (for either maven or gradle) as a guide to setting up both Android and Robolectric on your machine.

Gradle

testCompile "org.robolectric:robolectric:3.2.1"

Maven

<dependency>
   <groupId>org.robolectric</groupId>
   <artifactId>robolectric</artifactId>
   <version>3.2.1</version>
   <scope>test</scope>
</dependency>

Building And Contributing

Robolectric is built using Gradle. Both IntelliJ and Android Studio can import the top-level build.gradle file and will automatically generate their project files from it.

You will need to have portions of the Android SDK available in your local Maven artifact repository in order to build Robolectric. Copy all required Android dependencies to your local Maven repo by running:

./scripts/install-dependencies.rb

Robolectric supports running tests against multiple Android API levels. The work it must do to support each API level is slightly different, so its shadows are built separately for each. To build shadows for every API version, run:

./gradlew clean assemble install compileTest

Using Snapshots

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.

Gradle

repositories {
    maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
}

dependencies {
    testCompile "org.robolectric:robolectric:3.2.2-SNAPSHOT"
}

Maven

<repository>
  <id>sonatype-snapshpots</id>
  <url>https://oss.sonatype.org/content/repositories/snapshots</url>
</repository>

<dependency>
   <groupId>org.robolectric</groupId>
   <artifactId>robolectric</artifactId>
   <version>3.2.2-SNAPSHOT</version>
   <scope>test</scope>
</dependency>
