Release Notes: November 6, 2016

We will be deprecating dotnet-test-xunit once .NET CLI Preview 3 ships. The new Visual Studio runner (2.2 beta 4) supports .NET Core tests from the command line (dotnet test) as well as inside the next release of Visual Studio "15". There will be no more stand-alone .NET Core runner package.

Special Thanks

We wanted to highlight the amazing work that Hugh Bellamy has done recently. The majority of the new features that shipped in Beta 4 were provided by him, and there's more to come. Kudos, Hugh!

xUnit.net 2.2 v2 Beta 4

Core framework

Added support to [MemberData] to allow it to use members from derived types.
Dramatically improved support for generics in test methods (for complete coverage, see the unit tests).
Added support for theory methods with optional parameters.
Added support for theory methods with params arrays.
Added support for inherited traits attributes on test classes.
Added support for serializing multi-dimensional arrays in theory data.
Added a completion timestamp to xUnit v2 XML, and the HTML report.
Added a guard against theory data enumerators throwing.
Added a guard against theory data providers returning null.
More performance improvements.
BUG: Fixed an issue with serializing negative zero floats/doubles.
BUG: Fixed a bug with invalid characters written to ITestOutputHelper.

Assertion library

Assert.All now includes the faulty item in the failure message.
Improve compatibility of Assert.Equal when given two equivalent collections that are different types (f.e., string[] and List<string>).
Added a guard against IEnumerable implementations throwing.

Console runner

Added wildcard support (* and ?) in the -method command line option.

Extensibility

There is a slight breaking contract with XunitFilters wherein IncludedMethods was changed from exposed as HashSet<string> to ICollection<string>, in order to better support the new wildcard method feature. Hopefully this will have minimal impact on runner authors.

Visual Studio Runner 2.2 Beta 4

For information on using xUnit.net from within Visual Studio, see Running tests with Visual Studio in the Getting Started documentation.

Added support for .NET Core with .NET CLI Preview 3.
