Since the Documentation for xunit is new, you may need to create initial versions of those related topics. My Setup. Using the [Theory] attribute to create parameterised tests with [InlineData] xUnit uses the [Fact] attribute to denote a parameterless unit test, which tests invariants in your code. [Theory] and [InlineData] (along with sister attributes [ClassData] and [MemberData] , see the below blog post by Andrew Lock for more on them) save developers a lot of time when trying to write closely-related groups of unit tests.
