**Have 3 amigos.**

Always have a 3 amigos meeting.The 3 Amigos (in case you don't know)is a meeting where the Business Analyst presents requirements and test scenarios (collectively called a “feature”) for review by a member of the development team and a member of the quality assurance team.
This will help to build an *shared understanding* between them.

Make sure your develop the feature  as per this shared understanding and cover these test scenarios as part of testing.
