How to identify test data in Open Data views?

[SAPSupport]

May I know how can I distinguish testmail receiver from the email open data?

I want to collect the email performance data of customers who receive the email after email campaign launch, excluding the testmail data.

A possible way is to link email campaigns V2 view and performance data view using a JOIN (send, click, bounce, others) and filter out the entries which "campaign_type = test".
