### Question:
BooleanPreference extends AbsPreference<Boolean> { @Override public Boolean get() { return getPreferences().getBoolean(getKey(), getDefaultValue()); } BooleanPreference(SharedPreferences preferences, String key);  BooleanPreference(SharedPreferences preferences, String key, boolean defaultValue); @Override Boolean get(); @Override void set(Boolean value); @SuppressLint("CommitPrefEdits") void set(boolean value);  }### Answer:
@Test public void getValue() { boolean expected = false; String key = "testKey2"; preferences.edit().putBoolean(key, expected).commit(); BooleanPreference preference = new BooleanPreference(preferences, key); boolean result = preference.get(); assertThat(result).isFalse(); }
