### Question:
CustomTranslationCacheServiceImpl implements CustomTranslationCacheService { @Override public void addCustomTranslation(final String key, final String locale, final String customTranslation) { Map<String, String> localeAndCustomTranslation = Maps.newHashMap(); localeAndCustomTranslation.put(locale, customTranslation); getTenantCustomTranslationsCache().put(key, localeAndCustomTranslation); } CustomTranslationCacheServiceImpl(); @Override void addCustomTranslation(final String key, final String locale, final String customTranslation); @Override void updateCustomTranslation(final String key, final String locale, final String customTranslation); @Override void manageCustomTranslation(final String key, final String locale, final String customTranslation); @Override void removeCustomTranslations(final List<String> keys); @Override String getCustomTranslation(final String key, final String locale); @Override Map<String, Map<String, String>> getCustomTranslations(); @Override boolean isCustomTranslationAdded(final String key); @Override boolean isCustomTranslationActive(final String key, final String locale); @Override void loadCustomTranslations(final List<Entity> customTranslations);  }### Answer:
@Ignore @Test public void shouldAddCustomTranslation() { String key = "key"; String locale = "pl"; String translation = "translation"; customTranslationCacheService.addCustomTranslation(key, locale, translation); verify(customTranslations).put(key, localeAndCustomTranslation); }
