I have a customer who installed our package in their sandbox and their tests are failing in our namespace (That's just the information that the stacktrace shows).
The weird thing is that their tests are failing even without our apex trigger, I already had a call with them and I was not able to see the whole log due the limit restriction in size.
Our Apex Trigger logic is wrapped in a whole try/catch, so I don't see what else could affect them.
Have you ever seen a similar behavior?
Do you know what else could affect third party tests besides an apex trigger?
Thanks in advance.
