NUnit for MSBuild
This page describes how to use NUnit from MS build.
To use NUnit prior to 3.0 from MSBuild, see Working with TeamCity-provided NUnit task
To use NUnit 3.0 and above from MSBuild, see Working with NUnit 3.0
Working with NUnit Task in MSBuild Build
The information in this section is applicable if you are using NUnit prior to version 3.0. For later versions, refer to the section below.
This section assumes that you already have an MSBuild build script with a configured
NUnit task in it, and want TeamCity to track test reports without making any changes to the existing build script. Otherwise, consider adding NUnit build runner as one of the steps for your build configuration.
Using NUnitTeamCity task in MSBuild Build Script
TeamCity provides a custom
NUnitTeamCity task compatible with the
NUnit task from MSBuild Community tasks project. If you provide the
NUnitTeamCity task in your build script, TeamCity will launch its own test runner based on the options specified within the task. Thus, you do not need to have any NUnit runner, because TeamCity will run the tests.
In order to correctly use the
NUnitTeamCity task, perform the following steps:
Make sure the
teamcity_dotnet_nunitlaunchersystem property is accessible on build agents. Build agents running Windows should automatically detect these properties as environment variables. If you need to set them manually, see defining agent specific properties for more information.
Configure your MSBuild build script with
NUnitTeamCitytask using the following syntax:<UsingTask TaskName="NUnitTeamCity" AssemblyFile="$(teamcity_dotnet_nunitlauncher_msbuild_task)" /> <NUnitTeamCity Assemblies="@(assemblies_to_test)" />
The following attributes are supported by
Execution mode on a x64 machine. Supported values are: x86, x64 and ANY.
.NET Framework to use: v1.1, v2.0, v4.0, ANY. By default, the MSBuild runtime is used. Default is v2.0 for MSBuild 2.0 and 3.5. For MSBuild 4.0 default value is v4.0.

List of third-party NUnit addins to be used. For more information on using NUnit addins, refer to NUnit Addins Support page.
True to fail task, if any test fails.
List of assemblies to run tests with.
Set true, if you want to run each assembly in a new process.
NUnit task also supports additional attributes. For the list of available attributes refer to the Using NUnitTeamCity task in MSBuild Build Script section.
If you need the TeamCity test runner to support third-party NUnit addins, refer to the NUnit Addins Support section for the details.
Example (part of the MSBuild build script):
Be sure to replace "
." with "
_" when using System Properties in MSBuild scripts. For example, use
TeamCity also provides Visual Studio Solution Runner for solution files of Microsoft Visual Studio 2005 and above. It allows you to use MSBuild-style wildcards for the assemblies to run unit tests on.
Run NUnit tests using specific NUnit runner version:
Run NUnit tests with custom addins with NUnit 2.4.6:
Run NUnit tests with custom addins with NUnit 2.4.6 in per-assembly mode:
To make a TeamCity independent build script, consider the following trick:
The MSBuild property
TEAMCITY_VERSION is added to msbuild when started from TeamCity.
Working with NUnit 3.0
The information in this section is applicable if you are using NUnit 3.0 and above. For earlier versions of NUnit, refer to the section above.
Starting from version 3.0, NUnit supports TeamCity natively, so there is no need to use a special task for MSBuild as it was done for the earlier NUnit versions. The simplest way is to run the NUnit console via the standard Exec task. For example:
The NUnit console returns the number of failed tests as the positive exit code and, in case of the NUnit test infrastructure failure, as the negative exit code.
TeamCity controls the test execution progress, but the NUnit infrastructure exceptions may not allow TeamCity to collect the required information. That is why the IgnoreExitCode="True" attribute needs to be set, which will ignore the positive exit codes and will not interrupt the build due to several failed tests. The Error task will stop the build in case of the test infrastructure errors for the negative exit codes.
Besides the project file, you can define the MSBuild version and platform, the target, you can use profiles and other settings.
