NUnit 3.7 - May 29, 2017

This release of NUnit expands on parallel test execution to allow test methods to

be run in parallel. Please see the [Parallelizable Attribute](https://github.com/nunit/docs/wiki/Parallelizable-Attribute)

for more information.

NUnit 3.7 also drops the Portable build of the framework and replaces it with a

.NET Standard 1.3 version to compliment the .NET Standard 1.6 version. This change

enables several constraints and other features in the .NET Standard builds that

weren't available in portable like Path and Directory based asserts.

The AssertionHelper class has been deprecated because it is seldom used and has

not received any of the updates that Asserts and Constraints receive. If your code

is using the AssertionHelper class, we recommend that you migrate your asserts.

2205 Ncrunch: System.Xml.XmlException: Root element is missing, when adding NUnit 3.7.0

NUnit 3.5 - October 3, 2016

This is the first version of NUnit where the framework will be released separately from the

console runner, engine and other extensions. From this point forward, the NUnit Framework will be

released on its own schedule that is not bound to that of any other NUnit project and version numbers

may diverge over time.

This is also the first release where the NUnit Framework will not be included in the installer. Only

the console runner, engine and extensions will be available as an MSI installer. We recommend that you

use the NUnit NuGet packages for the framework, but a ZIP file with the binaries will also be available.

1739 Create separate copies of MockAssembly for framework, engine and extensions

NUnit 3.0.0 Beta 1 - March 25, 2015

A new Constraint, DictionaryContainsKeyConstraint, may be used to test that a specified key is present in a dictionary.

String arguments used in test case names are now truncated to 40 rather than 20 characters.

The class and method names of each test are included in the output xml where applicable.

The Silverlight runner now displays output in color and includes any text output created by the tests.

LevelOfParallelizationAttribute has been renamed to LevelOfParallelismAttribute.

We no longer create a separate framework build for .NET 3.5. The 2.0 and 3.5 builds were essentially the same, so the former should now be used under both runtimes.

There is now a master windows installer for the framework, engine and console runner.

440 Automatic selection of Test Engine to use

487 NUnitLite can't load assemblies by their file name

318 TestActionAttribute: Retrieving the TestFixture

482 nunit-console has multiple errors related to -framework option

504 Option --workers:0 is ignored

477 Assert does not work with ArraySegment

523 Provide an option to disable shadowcopy in NUnit v3

517 V2 FrameworkDriver does not make use of passed in TestEventListener

428 Add ExpectedExceptionAttribute to C# samples

The console now defaults to not using shadowcopy. There is a new option --shadowcopy to turn it on if needed.

The V2 framework driver now uses the event listener and test listener passed to it by the runner. This corrects several outstanding issues caused by events not being received and allows selecting V2 tests to be run from the command-line, in the same way that V3 tests are selected.

The engine API has now been finalized. It permits specifying a minimum version of the engine that a runner is able to use. The best installed version of the engine will be loaded. Third-party runners may override the selection process by including a copy of the engine in their installation directory and specifying that it must be used.

NUnit 3.0.0 Alpha 1 - September 22, 2014

Action Attributes have been added with the same features as in NUnit 2.6.3.

Does prefix operator supplies several added constraints.

TestContext now has a method that allows writing to the XML output.

TestContext.CurrentContext.Result now provides the error message and stack trace during teardown.

Console Issues Resolved (Old nunit-console project, now combined with nunit)

38 Confusing Excluded categories output

6 System.NullReferenceException on start nunit-console-x86

5 CI Server for nunit-console

NUnit 3.0.0 Release Candidate 3 - November 13, 2015

1015 Specifying .nunit project and --framework on command line causes crash

1003 Delete TeamCityEventHandler as it is not used

856 Extensions support for third party runners in NUnit 3.0

1017 Remove Assert.Multiple from framework

The engine now only sets the config file for project.nunit to project.config if project.config exists. Otherwise, each assembly uses its own config, provided it is run in a separate AppDomain by itself.

NOTE: It is not possible for multiple assemblies in the same AppDomain to use different configs. This is not an NUnit limitation, it's just how configs work!

NUnit 3.10.1 - March 12, 2018

Added a namespace to the props file included in the NuGet package to make it

compatible with versions of Visual Studio prior to VS 2017.

NUnit 2.9.3 - October 26, 2009

NUnit 3.0.0 Final Release - November 15, 2015

635 Mono 4.0 Support

NUnit 3.10 - March 12, 2018

This release adds a .NET Standard 2.0 version of the framework which re-enables

most of the features that have been missing in our earlier .NET Standard builds

like parallelism, timeouts, directory and path based asserts, etc. It also contains

numerous bug fixes and smaller enhancements. We've improved our XML docs,

fixed performance issues and added more detail to Multiple Asserts.

This release also contains source-indexed PDB files allowing developers to debug

into the NUnit Framework. This allows you to track down errors or see how the

framework works.

In order to support the .NET Standard 2.0 version, the NUnit project switched to

the new CSPROJ format and now requires Visual Studio 2017 to compile. This only

effects people contributing to the project. NUnit still supports building and

compiling your tests in older .NET IDEs and NUnit still supports older versions

of the .NET Framework back to 2.0. For contributors, NUnit can now compile all

supported targets on Windows, Linux and Mac using the Cake command line build.

NUnit 3.0.0 Alpha 3 - November 29, 2014

The -x86 command-line option is provided to force execution in a 32-bit process on a 64-bit system.

The -teamcity option is now supported.

A writeability check is performed for each output result file before trying to run the tests.

The console runner now runs tests in a separate process per assembly by default. They may still be run in process or in a single separate process by use of command-line options.

The console runner now starts in the highest version of the .NET runtime available, making it simpler to debug tests by specifying that they should run in-process on the command-line.

NUnitLite tests must reference both the nunit.framework and nunitlite assemblies.

The logic of runtime selection has now changed so that each assembly runs by default in a separate process using the runtime for which it was built.

On 64-bit systems, each test process is automatically created as 32-bit or 64-bit, depending on the platform specified for the test assembly.

331 Alpha 2 CF does not build

The NUnit and NUnitLite frameworks have now been merged. There is no longer any distinction between them in terms of features, although some features are not available on all platforms.

A number of previously unsupported features are available for the Compact Framework:

FileAssert, DirectoryAssert and file-related constraints

Generic methods as tests

RegexConstraint

TimeoutAttribute

The release includes two new framework builds: compact framework 3.5 and portable. The portable library is compatible with .NET 4.5, Silverlight 5.0, Windows 8, Windows Phone 8.1, Windows Phone Silverlight 8, Mono for Android and MonoTouch.

NUnit 3.12 - May 14, 2019

This release of NUnit finally drops support for .NET 2.0. If your application still

targets .NET 2.0, your tests will need to target at least .NET 3.5. Microsoft ended

support for .NET 2.0 on July 12, 2011. Microsoft recommends that everyone migrate

to at least .NET Framework 3.5 SP1 for security and performance fixes.

This release dramatically improves NUnit support for async tests including returning

ValueTask and custom tasks from tests, improved handling of SynchronizationContexts

and better exception handling.

The .NET Standard 2.0 version of NUnit continues to gain more functionality that

is found in the .NET 4.5 version of the framework like setting the ApartmentState

and enabling Timeout on tests.
