NUnit 3.0 Alpha 2 发布了，NUnit 是 JUnit 的 .NET 版，支持所有 .NET 语言，完全使用 C# 编写，并进行完全重新设计以利用很多高级的 .NET 语言特性，例如定制属性以及其他相关的反射功能。
与 Alpha 1 版本比较，该版本改进内容包括：
Breaking Changes
* The console runner no longer displays test results in the debugger.
* The NUnitLite compact framework 2.0 build has been removed.
*
All addin support has been removed from the framework. Documentation of
NUnit 3.0 extensibility features will be published in time for the beta
release. In the interim, please ask for support on the nunit-discuss
list.
General
* A separate solution has been created for Linux
* We now have continuous integration builds under both Travis and Appveyor
* The compact framework 3.5 build is now working and will be supported in future releases.
New Features
* The console runner now automatically detects 32- versus 64-bit test assemblies.
* The NUnitLite report output has been standardized to match that of nunit-console.
* The NUnitLite command-line has been standardized to match that of nunit-console where they share the same options.
* Both nunit-console and NUnitLite now display output in color.
*
ActionAttributes now allow specification of multiple targets on the
attribute as designed. This didn't work in the first alpha.
*
OneTimeSetUp and OneTimeTearDown failures are now shown on the test
report. Individual test failures after OneTimeSetUp failure are no
longer shown.
* The console runner refuses to run tests build with
older versions of NUnit. A plugin will be available to run older tests
in the future.
