在单元测试中排除IStringLocalizer / GetString

Question

我在asp.net核心的控制器中使用IstringLocalizer来读取共享资源。 在我有一个方法：

          foreach (var category in urlCategories)
        {
            if (category == _localizer.GetString("CategoryWebshop")) model.SelectedIndustries.Add(1);
            else if (category == _localizer.GetString("CategoryStore")) model.SelectedIndustries.Add(2);
            else if (category == _localizer.GetString("CategoryWebsite")) model.SelectedIndustries.Add(3);
            else if (category == _localizer.GetString("CategoryService")) model.SelectedIndustries.Add(4);
            else if (category == _localizer.GetString("CategoryProduction")) model.SelectedIndustries.Add(5);
            else if (category == _localizer.GetString("CategoryTrade")) model.SelectedIndustries.Add(6);
            else if (category == _localizer.GetString("CategoryRestaurant")) model.SelectedIndustries.Add(7);
            else if (category == _localizer.GetString("CategoryRealEstate")) model.SelectedIndustries.Add(8);
        }

在单元测试中，本地化程序的GetString不允许测试获得100％

如何解决问题或跳过/排除测试部分？ 感谢
