We are facing an issue while deploying Apex Trigger to production.
Please find the issue below.

Failure Message: "System.UnexpectedException: No more than one executeBatch can be called from within a testmethod. Please make sure the iterable returned from your start method matches the batch size, resulting in one executeBatch invocation.", Failure Stack Trace: "External entry point"

Please do the needful.
