Are you deploying Test class with Trigger ? if no then please add same in change set
Are you using SeeAllData in your test class ? if yes then removew seeAllData and create test data in test class
Hi Chauhan,

Any update on whether you were able to get around this issue? Was it an issue with a missing test class, or with SeeAllData=true but missing data? Or was it something else?

If something else, did you get test class failures along with the 0% code coverage error? Or did all your unit tests pass, with the 0% code coverage error the only error that was raised?
