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 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 3.7 - 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 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.

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.

• 635 Mono 4.0 Support

NUnit 3.0.0 Release Candidate 3 - November 13, 2015

Engine

• 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!

Issues Resolved

• 856 Extensions support for third party runners in NUnit 3.0
• 1003 Delete TeamCityEventHandler as it is not used

  NOTE: The nunit3-console runner cannot run tests that reference the portable build. You may run such tests using NUnitLite or a platform-specific runner.

• TestCaseAttribute and TestCaseData now allow modifying the test name without replacing it entirely.

• The Silverlight packages are now separate downloads.

NUnitLite

• The NUnitLite runner now produces the same output display and XML results as the console runner.

Engine

• The format of the XML result file has been finalized and documented.

Console Runner

NUnit 3.0.0 Beta 5 - October 16, 2015

Framework

• Parameterized test cases now support nullable arguments.
• The NUnit framework may now be built for the .NET Core framework. Note that this is only available through building the source code. A binary will be available in the next release.

Engine

• The engine now runs multiple test assemblies in parallel by default
• The output XML now includes more information about the test run, including the text of the command used, any engine settings and the filter used to select tests.
• Extensions may now specify data in an identifying attribute, for use by the engine in deciding whether to load that extension.

Console Runner

• The console now displays all settings used by the engine to run tests as well as the filter used to select tests.
• The console runner accepts a new option --maxagents. If multiple assemblies are run in separate processes, this value may be used to limit the number that are executed simultaneously in parallel.
• The console runner no longer accepts the --include and --exclude options. Instead, the new --where option provides a more general way to express which tests will be executed, such as --where "cat==Fast && Priority==High". See the docs for details of the syntax.
• The new --debug option causes NUnit to break in the debugger immediately before tests are run. This simplifies debugging, especially when the test is run in a separate process.

Issues Resolved

• 41 Check for zeroes in Assert messages
• 254 Finalize XML format for test results
• 275 NUnitEqualityComparer fails to compare IEquatable<T> where second object is derived from T

NUnit 3.0.0 Beta 1 - March 25, 2015

General

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

Framework

• 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.
• A new Constraint, DictionaryContainsKeyConstraint, may be used to test that a specified key is present in a dictionary.
• LevelOfParallelizationAttribute has been renamed to LevelOfParallelismAttribute.
• The Silverlight runner now displays output in color and includes any text output created by the tests.
• The class and method names of each test are included in the output xml where applicable.
• String arguments used in test case names are now truncated to 40 rather than 20 characters.

Engine

• 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.
• 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.

Console

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

Issues Resolved

• 224 Silverlight Support
• 318 TestActionAttribute: Retrieving the TestFixture
• 428 Add ExpectedExceptionAttribute to C# samples
• 440 Automatic selection of Test Engine to use

NUnit 3.0.0 Alpha 3 - November 29, 2014

Breaking Changes

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

Framework

• 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.
• 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.
• A number of previously unsupported features are available for the Compact Framework:
  • Generic methods as tests
  • RegexConstraint
  • TimeoutAttribute
  • FileAssert, DirectoryAssert and file-related constraints

Engine

• 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.

Console

• 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.
• The -x86 command-line option is provided to force execution in a 32-bit process on a 64-bit system.
• A writeability check is performed for each output result file before trying to run the tests.
• The -teamcity option is now supported.
