xUnit1015

Cause

This rule is triggered when a [MemberData] attribute does not point to a member.

Reason for rule

The [MemberData] attribute must point to a valid data member to provide data, or else it will fail at runtime. Using nameof is a good way to get compiler and Intellisense help to ensure you are using a valid member name.

How to fix violations

To fix a violation of this rule, update the name used in [MemberData] to point to at a data member.
