### Question:
Utils { public static synchronized long getTotalRAM(Context context) { long totalRAM = 0; try { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) { ActivityManager.MemoryInfo mi = new ActivityManager.MemoryInfo(); ActivityManager activityManager = (ActivityManager) context.getApplicationContext().getSystemService(Activity.ACTIVITY_SERVICE); activityManager.getMemoryInfo(mi); return mi.totalMem; } else { RandomAccessFile reader = new RandomAccessFile("/proc/meminfo", "r"); String load = reader.readLine().replaceAll("\\D+", ""); totalRAM = (long) Integer.parseInt(load); reader.close(); } } catch (IOException e) { totalRAM = 0; } return totalRAM; }  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 shouldBeAbleToGetDeviceTotalRAM() { long totalRAM = Utils.getTotalRAM(context); assertThat(totalRAM, is(notNullValue())); }
