Xunit.EnumMemberData

Xunit.EnumMemberData is a library containing one attribute ([EnumMemberData]) to simplify using enums when writing theories (parameterized unittests) using xunit.

By type of enum

[Theory] [EnumMemberData(typeof(Gender))] public void TestWithAllEnumValues_UsingEnumMemberData_ByType(Gender gender) { _outputWriter.WriteLine($"Gender: {gender}"); }

By property (or method) with simple return value

[Theory] [EnumMemberData(nameof(Genders))] public void TestWithAllEnumValues_UsingEnumMemberData_ByProperty(Gender gender) { _outputWriter.WriteLine($"Gender: {gender}"); } // Normally, xunit uses return values like IEnumerable<object[]> public static IEnumerable<Gender> Genders { get { return Enum.GetValues(typeof(Gender)).Cast<Gender>(); } }
