#### General

- Tests may now be loaded and run from a shared directory specified as a UNC path.
- Tests may now be run under .NET 4.5.
- When running under a debugger, any nunit-agent process launched will break and allow the option to continue debugging the agent process as well.
- J# and old-style managed C++ samples have been removed. F# samples are now included. Code samples are no longer included in the standard installs but are available as a separate download. All samples now use VS2010 projects.

#### Development

- The source code now includes solutions for VS2010 and VS2012. The VS2008 solution has been removed.
- The NAnt build now uses NAnt 0.92.
- NSubstitute has been upgraded to version 1.4.3.

#### Framework

- When running under .NET 4.5, async test methods are now supported. For test cases returning a value, the method must return Task<T>, where T is the type of the returned value. For single tests and test cases not returning a value, the method may return either void or Task.
- The Platform attribute has been upgraded to recognize .NET 4.5, MaxOsX and XBox.
- TestCaseSource may now specify a class that implements IEnumerable without specifying the name of a method.

### NUnit 2.6 Beta 4 - Version 2.6.0.12017 - January 17, 2012

#### General

- NUnit no longer stores settings in the test configuration file, as it did in earlier versions. Specifically, we no longer recognize or support OldStyleTestCases, ApartmentState, ThreadPriority or DefaultLogThreshold in the configuration file. Further details on each of these features are included in the appropriate sections below.
- The TestRunner interface has been modified. Applications using this interface will need to be modified but general users are not effected.
- The build now uses the NAnt 0.91 final release.

#### Framework

- User-defined equality comparers specified with the Using syntax element may now be used with arrays and dictionaries. Essentially, this means that there are no longer any restrictions on the Types for which a user-defined equality comparer may be specified.
- So-called "old-style" tests, identified by having a name beginning with "Test" are no longer supported in NUnit 2.6.
- Setting a ThreadPriority for the test runner thread is no longer supported under NUnit 2.6.

#### Console

- The following new command-line options are provided:
  - -stoponerror causes execution of the test run to terminate immediately on the first test failure or error.
  - -apartment is used to specify the ApartmentState (STA or MTA) of the test runner thread. Since the default is MTA, the option is only needed to force execution in the Single Threaded Apartment.

#### Gui

- A number of new settings are available using the Settings Dialog:
  - The Tree Display page allows the user to select alternate image sets for use in the test tree. Additional user-provided image sets may be added if desired.
  - The Text Output page allows setting the threshold for capture and display of log4net output (previously controlled by the test config file).
- By default, test Cases under a Theory that fail an assumption are no longer shown in the tree. A context menu item has been added to allow the user to view them.
- The properties dialog has been redesigned to be more compact and readable.
- The context menu for the test tree has been simplified.

#### Bug Fixes

- 605034 Log4net not working with NUnit
- 708173 NUnit's logic for comparing arrays - use Comparer<T[]> if it is provided
- 719184 Platformdependency in src/ClientUtilities/util/Services/DomainManager.cs:40

- 912955 Project files missing in source code package

### NUnit 2.6 Beta 3 - Version 2.6.0.11340 - December 6, 2011

#### Framework

- The Constraint syntax now supports Is.Positive, which is interpreted as greater than zero, and Is.Negative, which is interpreted as less than zero.

#### Bug Fixes

- 892844 Not using Mono 4.0 profile under Windows
- 892845 "Mono" is not clearly shown in About box or Test Assemblies dialog
- 892847 Gui offers to load assemblies under a lower CLR version
- 893919 DelayedConstraint fails polling properties on references which are initially null
- 893991 When working directory contains # sign, it is truncated
- 898192 Feature Request: Is.Negative, Is.Positive
- 898256 IEnumerable for Datapoints doesn't work
- 898850 NUnit 2.6 beta 2 crashes on assemblies without tests

### NUnit 2.6 Beta 2 - Version 2.6.0.11324 - November 20, 2011

#### General

- NUnit's executables now use config files that allow smoother running of mixed assemblies built for .NET 2.0 under .NET 4.0.
- When opening Visual Studio formatted solutions, NUnit now uses the solution configuration by default, resulting in changed behavior from previous releases. The Settings Dialog may be used to revert NUnit to the earlier behavior, which ignored solution configurations.
- Changing the URL to be used for NUnit help through the config file is no longer supported.

#### Framework

- TestCaseAttribute now accepts Explicit and Reason named parameters.
- TestCaseSourceAttribute now accepts a Category named parameter.
- TestCaseData now supports marking individual test cases as Explicit.
- EqualConstraint now recognizes and uses IEquatable<T> if it is implemented on either the actual or the expected value. The interface is used in preference to any override of Object.Equals(), so long as the other argument is of Type T. Note that this applies to all equality tests performed by NUnit.
- When Assert.Throws() fails due to an exception of the wrong Type being thrown, the error message now includes the Message and Stack Trace from the exception.
- The constraint syntax now supports Has.Exactly(n)... in place of Has.Some... in order to allow tests over collections that must be satisfied a specific number of times.
- The Using(...) syntactic element may now be repeated multiple times in an expression, so long as each comparer applies to a different Type. NUnit will use the appropriate comparer, depending on the Type of the arguments. Among other things, this allows overriding the default NUnit comparison of collections.
- Documentation is provided for the previously undocumented TestContext. A new property TestContext.WorkDirectory allows tests to access the name of a directory to be used for file output. This directory may be specified by use of the /work option of nunit-console.

#### Gui

- The test reload functionality in the Gui has been rewritten and simplified so that the same logic is used for all cases where the visual state of the tree is to be recovered. Test results are now found even if changes to the assembly have resulted in the assignment of new ids to the tests.
- The Gui now displays invalid tests in red immediately upon load, without waiting for the user to run them. Tests marked with the IgnoreAttribute are displayed in yellow immediately as well.
- The directory containing the log files may be opened directly from the Gui by use of a new item on the Tools menu.
- Test summary results are truncated when the window size is too small. The full summary is displayed when hovering over the field.
- A number of new settings are available using the Settings Dialog:
  - The Project Editor page allows the user to select whether the NUnit Project Editor or another external program will be used when editing the settings file.
  - The Runtime Selection page allows enabling or disabling automatic detection of the target runtime for each test assembly.
  - The Advanced Loader Settings page now allows specifying the argument to use in calling SetPrincipalPolicy for each test AppDomain.
  - The Visual Studio page now includes a setting that enables or disables the use of solution configs when loading Visual Studio solution files.
  - The Internal Trace page now shows the directory path to which log files will be saved.
- The location of the settings dialog under the Windows AppData directory has been changed from Roaming to Local. Users will need to reset their preferences in some cases.

### NUnit 2.6 Beta 1 - Version 2.6.0.11240 - August 28, 2011

#### General

- NUnit is now built using .NET 3.5. All NUnit assemblies and most tests target .NET 2.0 but the full set of tests requires 3.5 to execute.
- The build script now supports building from source under .NET 4.0. The script selects either .NET 3.5 or .NET 4.0 to perform the build, depending on what is available.
- NAnt 0.91 alpha2 release is now used for building on Windows. The 0.90 release is still used on Linux.
- Support for .NET 1.0 / 1.1 is no longer included in the main distribution for NUnit but is provided as a separate package.
- NUnit Mocks is now deprecated. All classes are now marked as obsolete.
- NUnit now uses the NSubstitute mock framework its own tests. A copy of the NSubstitute dll is included in the distribution.

#### Framework

- NUnit now supports composable Action Attributes, which allow the test developer to put reusable test actions into attributes and attach these actions to suites, tests, and test cases. The actions can run arbitrary code before and after suites, tests, and test cases execute. It enables the test developer to build smaller reusable actions and to compose them in unique ways for each suite, test, or test case.

  Note: This feature is experimental and details are likely to change in the final release.

- PlatformAttribute accepts "Net-3.0", "Net-3.5", "Mono-3.0" and "Mono-3.5" as arguments. Since these frameworks all use the 2.0 runtime, the semantics of their use is slightly different from other key words. The "3.5" arguments also include "3.0" and "2.0" and the "3.0" arguments include "2.0" in their interpretation.
- TestFixtureAttribute now accepts a Category named parameter, allowing individual fixture instances to be included in or excluded from a test run.

#### Console

- The .NET 1.1 build of nunit-console no longer supports the -process or -framework option. There is no automatic runtime detection and tests execute under same runtime as the console runner itself. If this functionality is needed when running tests under .NET 1.1, use the standard console runner to execute the tests in a separate process.
- The following new command-line options are provided:
  - -result is a synonym for -xml, specifying the file to be used for output of the test results in XML form. The -xml option is still recognized but will be removed in a future release.
  - -noresult allows supressing the xml result output entirely.
  - -work is used to specify the directory to be used for output files. Any relative paths specified with the -output, -err or -result options are resolved using this directory as a base.
  - -runlist allows the user to specify a file that contains the names of the tests to be executed rather than listing them directly on the command line.

#### Gui

- The Project Editor is now a separate program, which may be executed directly or run through the Project | Edit dropdown menu of the NUnit GUI. The editor now provides two main views of the project: a property-oriented view based on the Project Editor that was built into earlier versions of the NUnit GUI and an xml view, which allows simple editing of the .nunit file.

#### PNUnit

- The PNUnit code has been updated using the latest build from the developers at Codice Software and additional examples are provided in the source.

#### Bug Fixes

- 691129 Add Category parameter to TestFixture
- 692180 Script should allow building for net-2.0 under 3.5 or 4.0
