### Question:
Utils { public static synchronized int getScreenHeight(Context context) { int height = 0; try { WindowManager wm = (WindowManager) context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); Point size = new Point(); display.getSize(size); height = size.y; } catch (Exception e) { height = 0; } return height; }  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 shouldBeAbleToGetDeviceScreenHeight() { long screenHeight = Utils.getScreenHeight(context); assertThat(screenHeight, is(notNullValue())); }
