Release Notes
NUnit 2.6 Final Release - Version 2.6.0.12051 - February 20, 2012
General
- 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'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.
- 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.
- 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
- DefaultLogThreshold
- Changing the URL to be used for NUnit help through NUnit's config file
is no longer supported.
Development
- NUnit is now built using .NET 3.5 or higher. All NUnit assemblies and most tests
target .NET 2.0 but the full set of tests requires 3.5 or greater to execute.
The build script selects either .NET 3.5 or .NET 4.0 to perform the build,
depending on what is available. A Visual Studio 2008 solution is also provided.
- NAnt 0.91 release is now used for building.
- The Windows installer is now built using WiX 3.5, upgraded from 2.0.
- The TestRunner interface has been modified. Applications using this
interface will need to be modified but general users are not effected.
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.
- The following Attributes have changes in NUnit 2.6:
- 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.
- PlatformAttribute accepts "Windows8", "Windows2012Server", "Net-3.0",
"Net-3.5", "Mono-3.0" and "Mono-3.5" as arguments.
Note: Since the 3.0 and 3.5
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.
- The following additions have been made to the Constraint syntax:
- User-defined equality comparers specified with the Using syntax
element may now be used with collections, arrays and dictionaries. The
Using(...) syntactic element may 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, arrays and dictionaries.
- Is.Positive may be used as a synonym for Is.GreaterThan(0).
- Is.Negative may be used as a synonym for Is.LessThan(0).
- Has.Exactly(n)... may be used in place of Has.Some...
in order to allow tests over collections that must be satisfied a
specific number of times.
- 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.
- Visual Basic users may now use Assert.ByVal rather than Assert.That()
to avoid errors when the first argument is a property with a non-public setter.
- 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.
- 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:
- -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.
- -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.
- 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.
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.
- 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 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.
- 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).
- 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.
- 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.
- 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.
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.
