Release Notes: December 20, 2015

xUnit.net v2 2.2 Beta 1

Core framework

• Added event assertions:
  • Assert.Raises
  • Assert.RaisesAsync
  • Assert.RaisesAny
  • Assert.RaisesAnyAsync
  Assertion is done with three lambdas:
  • A subscription lambda (i.e., handler => myClass.MyEvent += handler)
  • An unsubscription lambda (i.e., handler => myClass.MyEvent -= handler)
  • An action which causes the event to be raised
  For examples, see the unit tests.
• Added Assert.PropertyChangedAsync.
• Added support for sets to Assert.Equal.
• Added Skip property to theory data attributes.
• Added support for trait attributes at the assembly level.
• Updated NUnitXml.xslt to be compatible with NUnit 2.5 output.
• Improved console runner error message when an unknown switch is passed.
• BUG: Fixed an issue where PCL unit tests were run in desktop mode instead of PCL mode, which caused issues when linking against PCL-based extensibility libraries.
• BUG: Fixed an issue when running unit tests from UNC paths (not mapped to a drive letter).
• BUG: ArgumentFormatter was causing a null reference exception when attempting to format an unbound generic type.
• BUG: Fixed an issue where trying to perform multiple XML transformations at the same time caused a file sharing violation.

Console Runner

• Added a new JSON reporter with the -json switch.
• Made console runner exit codes consistent and predictable.
• Ensured xunit.runner.console NuGet package is marked with developmentDependency=true.

MSBuild Runner

• Added IgnoreFailures option, which allows the task to return a success exit code even when one or more tests have failed.
• Added a new JSON reporter with the json reporter type.

Extensibility

• Added additional diagnostic messages to TheoryDiscoverer.
