How do you test an Android application across multiple Activities?

Question

We are building a complex Android application consisting of many screens and workflows spread across many Activities. Our workflows are similar to what you might see on a Ba

Answer 1

You could always use Robotium. It supports blackbox testing just like Selenium but for Android. You will find it at Robotium.org

Answer 2

This answer is based on the accepted answer but modified to solve the timing issue which for me became consistent after adding about a half dozen tests. @pajato1 gets the credit for solving the timing issue, as cited in the accepted answer comments.

/**
 * Creates a test Activity for a given fully qualified test class name.
 *
 * @param fullyQualifiedClassName The fully qualified name of test activity class.
 *
 * @return The test activity object or null if it could not be located.
 */
protected AbstractTestActivity getTestActivity(final String fullyQualifiedClassName) {
    AbstractTestActivity result = null;

    // Register our interest in the given activity and start it.
    Log.d(TAG, String.format("Running test (%s) with main class: %s.", getName(), fullyQualifiedClassName));
    instrumentation = getInstrumentation();

    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.setClassName(instrumentation.getTargetContext(), fullyQualifiedClassName);
    // Wait for the activity to finish starting
    Activity activity = instrumentation.startActivitySync(intent);

    // Perform basic sanity checks.
    assertTrue("The activity is null!  Aborting.", activity != null);
    String format = "The test activity is of the wrong type (%s).";
    assertTrue(String.format(format, activity.getClass().getName()), activity.getClass().getName().equals(fullyQualifiedClassName));
    result = (AbstractTestActivity) activity;

    return result;
}
