I have a custom trigger written on a managed package object. When I run All tests, the trigger shows 100% coverage in SB. However, I am not able to find the class that covers it. I downloaded all the classes in my IDE and searched for the object API name. However, it does not pull up anything.
Also, while deploying to production, it fails.
Can a managed package test class cover a non-managed package trigger? And could it have failed in Production because we ran Default tests?
