NUnit V2 2.5.3

NUnit 2.5.3 - Version 2.5.3.9345 - December 11, 2009

Note: This is the first release of NUnit on Launchpad.

New Features

* Test execution under .NET 4.0 is now supported. It may be selected in the
  Gui runner or using the console runner /framework option. NUnit test projects
  may specify .NET 4.0 as the required framework to be used for loading the
  project. PlatformAttribute allows testing for .NET 4.0.

* The distribution now includes nunit-agent-x86.exe, which is used for running
  tests in a separate process under nunit-x86.exe or nunit-console-x86.exe when
  the target framework is .NET 2.0 or greater.

* Static methods Contains.Substring() and Contains.Item() have been added to the
  NUnit syntax for compatibility with NUnitLite.

* Non-public test fixtures are now allowed in all cases, whether the
  TestFixtureAttribute is present or not.

* Abstract classes may now be marked with TestFixtureAttribute to indicate that
  derived classes are to be treated as test fixtures. The abstract class is no
  longer marked as invalid.

* Fixtures without tests are no longer shown as non-runnable but are simply
  executed. If the fixture setup or teardown does not cause an error, they are
  reported as inconclusive.

Bug Fixes

* Reloading tests in the Gui no longer uses the default runtime if a different
  runtime was previously selected.

* Thread principal is now saved before each test and restored afterward eliminating
  failures under .NET 4.0.

* Assume.That() overload with a message no longer results in test failure.

* An expected Result of null is now handled correctly on parameterized tests.

* Duplicate caching of metadata has been eliminated, resolving a load performance
  problem when many methods are inherited from a base class.

* The names of nested generic and non-generic classes are now displayed correctly.

* Assert.Catch<T> now correctly returns exception type T rather than System.Exception.

* ValueSourceAttribute now works correctly when used with an external type.

* The /domain=None option on nunit-console once again works correctly.

* Parameterized test fixture names are now displayed with the actual arguments used
  so that failures may be associated with the correct instantiation of the fixture.

* Test labels for generics are now displayed correctly by the console runner and
  in the Gui text output tab.

* Generic fixtures without type attributes provided are now shown as non-runnable
  rather than causing a runtime error. (1)

* Use of an unknown file type in the console command line no longer causes an error. (2)

* A number of tests that ran incorrectly under Linux have been fixed.

* A number of tests failing under .NET 4.0 have been fixed.

Notes

   1. As a side effect of this fix, TestFixtureAttribute on a base class is
      overridden by a TestFixtureAttribute on the derived class.

   2. This was originally reported as "crash when using /option in linux."
