xUnit - Strongly Typed Test Data
xUnit has a quirky system for consuming test data. Strongly typed test data can be specified with the MemberData attribute and the Theory attribute but it’s not intuitive.
The MemberData attribute allows you to specify a getter that returns an enumeration of object arrays. It expects the type to be IEnumerable<object[]>. The trick is to return a List with multiple object arrays in it. Here is some example code for the getting the strongly typed test data. This makes for much cleaner unit testing.

The getter for the test data:
This is the SampleData class:
This is how your unit test can consume the strongly typed data:
