A theory is a parametric unit test that allows you to represent a set of unit tests sharing the same structure. To refactor our own test cases, we'll need to define a test method with the [Theory] attribute, and for each test case with data, we'll need to add an [InlineData(input, output)] attribute. This is also the test framework I use on most of my projects. More details can be found on xUnit’s Github page. xUnit.net is a free, open source, community-focused unit testing tool for the .NET Framework.
