### Question:
Utils { public static synchronized Map<String, String> getPackageInfo(Context context) { Map<String, String> packageInfo = new HashMap<String, String>(); packageInfo.put(Device.VERSION_CODE, asEmpty(String.valueOf(getVersionCode(context)))); packageInfo.put(Device.VERSION_NAME, asEmpty(String.valueOf(getVersionName(context)))); packageInfo.put(Device.PACKAGE, asEmpty(context.getPackageName())); return packageInfo; }  static synchronized Map<String, String> getMemoryInfo(Context context); static synchronized boolean hasExternalMemory(); static synchronized long getTotalExternalMemorySize(); static synchronized long getAvailableExternalMemorySize(); static synchronized long getTotalInternalMemorySize(); static synchronized long getAvailableInternalMemorySize(); static synchronized long getTotalRAM(Context context); static synchronized boolean isConnected(Context context); static synchronized boolean isWifiEnabled(Context context); static synchronized String getNetworkType(Context context); static synchronized Map<String, String> getDisplayInfo(Context context); static synchronized String getScreenDensity(Context context); static synchronized int getScreenHeight(Context context); static synchronized int getScreenWidth(Context context); static synchronized String asEmpty(String value); static synchronized String getCountryCode(Context context); static synchronized String getCountryName(Context context); static synchronized Map<String, String> getLocaleInfo(Context context); static synchronized String getLanguageCode(Context context); static synchronized String getLanguageName(Context context); static synchronized String getTimezone(); static synchronized String getVersionName(Context context); static synchronized String getVersionCode(Context context); static synchronized Map<String, String> getPackageInfo(Context context); static synchronized Map<String, String> getBuildInfo(); static synchronized String getUUID(Context context); static final String NETWORK_TYPE_WIFI; static final String NETWORK_TYPE_MOBILE; }### Answer:
@Test public void shouldBeAbleToGetPackageInfo() { Map<String, String> packageInfo = Utils.getPackageInfo(context); assertThat(packageInfo.get(Device.VERSION_NAME), is(notNullValue())); assertThat(packageInfo.get(Device.VERSION_CODE), is(notNullValue())); assertThat(packageInfo.get(Device.PACKAGE), is(notNullValue())); }
