در عکس ارسال شده، تست‌های نوشته شده برای تمامی لایه‌ها به صورت جدا ایجاد شده‌است.
تست مربوط به UserService:

در عکس بالا قسمت‌هایی که تست شده‌اند، با رنگ سبز مشخص می‌شود و اگر قسمتی از کد تست نشده باشد، با رنگ قرمز مشخص می‌شود. 

برای مثال در عکس زیر مشخص شده‌است که برای فایل ApplicationConfiguration هیچ تستی نوشته نشده‌است.

اگر از CICD استفاده میکنید، می‌توانید در قسمت CI پروژه، هربار دستورات بالا را اجرا کنید و Code coverage مربوط به هر Build را به صورت جداگانه در کنار فایل‌های آپلود شده داشته باشد.
نکته: برای اجرای دستورات بالا و ساخت گزارش باید ورژن SDK نصب شده بر روی سیستم شما برابر 2.2.401 یا بیشتر باشد و ورژن Microsoft.NET.Test.Sdk برابر 16.5.0 یا بیشتر باشد.
