### Question:
Utils { public static synchronized String getNetworkType(Context context) { String networkType = ""; try { ConnectivityManager cm = (ConnectivityManager) context.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE); if (cm != null) { NetworkInfo activeNetwork = cm.getActiveNetworkInfo(); if (activeNetwork != null) { int type = activeNetwork.getType(); boolean isWifi = (type == ConnectivityManager.TYPE_WIFI || type == ConnectivityManager.TYPE_WIMAX); boolean isMobile = (type == ConnectivityManager.TYPE_MOBILE); if (isWifi) { networkType = NETWORK_TYPE_WIFI; } if (isMobile) { networkType = NETWORK_TYPE_MOBILE; } } } } catch (Exception e) { networkType = ""; } return networkType; }  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 shouldBeAbleToGetDeviceNetworkType() { String networkType = Utils.getNetworkType(context); assertThat(networkType, is(notNullValue())); }
