移动应用程序上的多语言测试（android/ios）

Question

我们正在为我们的产品开发移动应用程序。由于这些应用程序支持多种语言（英语、法语、意大利语、德语等），因此如何在语言正确与否的情况下对其进行自动化测试。我们必须逐字逐句手动完成。如果有任何方法，我们可以在开发环境中或通过电话自动进行语言测试和验证。

Answer 1

如果您正确使用了 strings.xml，您的应用就没有理由出错。要对您想要的任何功能进行自动化 ui 测试，您可以使用 espresso。你应该把这个类放在 androidTest 下 espresso 中的示例测试如下所示。

@RunWith(AndroidJUnit4.class)
public class MainActivityTest {

 @Rule
public ActivityTestRule<MainActivity> mainActivityTestRule = new ActivityTestRule<>(MainActivity.class);

@Test
public void changeLocalization() {
    changeLocal(TURKISH_ABBREVATION); // For french it is "fr"
    onView(withText(TURKISH_TEXT)).check(matches(isDisplayed())); // This is where the magic happens. If you want to check all texts you should add all of them but one is enough to see if strings are translated.
}
public void changeLocal(String language) {
    Context context = InstrumentationRegistry.getTargetContext();
    LocaleHelper.setLocale(context, language);
}

用于更改语言环境的语言环境助手类（您可以在 SO 中找到）

public final class LocaleHelper {

    private static final String SELECTED_LANGUAGE = "Locale.Helper.Selected.Language";

    /**
     * Prevents the util class from being instantiated.
     */
    private LocaleHelper() {
    }


    public static Context onAttach(Context context) {
        final String lang = getPersistedData(context, Locale.getDefault().getLanguage());
        return setLocale(context, lang);
    }

    public static Context onAttach(Context context, String defaultLanguage) {
        final String lang = getPersistedData(context, defaultLanguage);
        return setLocale(context, lang);
    }

    public static String getLanguage(Context context) {
        return getPersistedData(context, Locale.getDefault().getLanguage());
    }

    public static Context setLocale(Context context, String language) {
        persist(context, language);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            return updateResources(context, language);
        }

        return updateResourcesLegacy(context, language);
    }

    private static String getPersistedData(Context context, String defaultLanguage) {
        final SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getString(SELECTED_LANGUAGE, defaultLanguage);
    }

    private static void persist(Context context, String language) {
        final SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        final SharedPreferences.Editor editor = preferences.edit();

        editor.putString(SELECTED_LANGUAGE, language);
        editor.apply();
    }

    @TargetApi(Build.VERSION_CODES.N)
    private static Context updateResources(Context context, String language) {
        final Locale locale = new Locale(language);
        Locale.setDefault(locale);

        final Configuration configuration = context.getResources().getConfiguration();
        configuration.setLocale(locale);
        configuration.setLayoutDirection(locale);

        return context.createConfigurationContext(configuration);
    }

    private static Context updateResourcesLegacy(Context context, String language) {
        final Locale locale = new Locale(language);
        Locale.setDefault(locale);

        final Resources resources = context.getResources();

        final Configuration configuration = resources.getConfiguration();
        configuration.locale = locale;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            configuration.setLayoutDirection(locale);
        }

        resources.updateConfiguration(configuration, resources.getDisplayMetrics());
        return context;
    }
}

当然你应该在gradle中添加espresso的必要依赖
