The reason for this attribute is to let the users create their own implementation of test categories. - test framework (discovery, etc) deals with TestCategoryBaseAttribute. - The reason that TestCategories property is a collection rather than a string, is to give more flexibility to the user. For instance the implementation may be based on enums for which the values can be OR'ed in which case it makes sense to have single attribute rather than multiple ones on the same test.

Users can use this to plug-in custom assertions through C# extension methods.

Users can use this to plug-in custom assertions through C# extension methods. For instance, the signature of a custom assertion provider could be "public static void ContainsWords(this StringAssert customAssert, string value, ICollection substrings)" Users could then use a syntax similar to the default assertions which in this case is "StringAssert.That.ContainsWords(value, substrings);" More documentation is at "https://github.com/Microsoft/testfx-docs".
