So my nunit 2.6 tests run in team city, the results appear in a 'tests' tab. I just select the built in nunit build step, type the name of the file with the tests in "Runs Tests from:" and the name of the category(s) in "NUnit categories include:"
However, If I upgrade my tests and select NUnit3 from the "NUnit runner" drop down things start to go wrong.
After much googling and mucking round for command lines and console runners I can't get this working with the full 'results in a tab' level of compatibility.
There is a lot of advice out there on how to make this work, but the best articles are at least a year old and I'm not at all clear that they apply to 3.5.0
Has anyone got this fully working or is it no longer supported? Can you explain how you managed it?
NUnit 3.5.0 does work with TeamCity, but it requires that you use the NUnit TeamCity Event Listener Extension. You can install it along with the NUnit Console Runner package or use the NUnit Console Runner with Extensions which includes the TeamCity extension along with other commonly used NUnit extensions.
Once you have the extension, TeamCity should automatically add the --teamcity command line option to the nunit3-console.exe.
Check here more information on the various NUnit Runner NuGet packages and what is included in each.
You add these packages to one of your test projects. That will cause them to be installed in the package directory of your solution root. From there, the built in NUnit 3 step will work, just update the executable location to point to 3.5.0. See the Getting Started With NUnit and TeamCity document. I would use the Case 4, NUnit Build Step.
If you only want to test certain categories, you will need to add your --where clause as an additional command line parameter.
I am using an NUnit 3 runner in a TeamCity 9.1.6 step. I've chosen "JetBrains dotCover" as the .NET Coverage tool, and now I'd like this step to use the xxx.sln.DotSettings file that we've put in source control and that we're sharing across devs in Visual Studio, rather than to duplicate settings to TeamCity Filters, Attribute Filters etc. Is this possible in TeamCity?
It is not possible from the box now. It is a great idea, could you create an issue here https://youtrack.jetbrains.com/
But there is a simple workaround:
you could parse dotSettins manually on the first step
publish configuration parameters using ##teamcity[setParameter name='ddd' value='fff'] TeamCity service message (see for details https://confluence.jetbrains.com/display/TCD9/Build+Script+Interaction+with+TeamCity)
use those configuration parameters in the appropriate fields for dotCover like %ddd%
I'm currently moving one of our projects to DNX (.NET Core now) and I was forced to update to nunit3. Because of other considerations, we run compile the test project as a console app with its own entry point, basically self-hosting the NUnit runner.
I now need to report the results to TeamCity via the XML Reporter, which doesn't seem to parse Nunit3 TestResults.xml files.
Any advice on how to work around this?
The NUnit 3 console has the option to produce results formatted in the NUnit 2 style.
Use the option:
--result=[filename];format=nunit2
Docs: https://github.com/nunit/nunit/wiki/Console-Command-Line
To add to the answer above:
NUnitLite inherits the --result CLI parameter which seems to do the trick.
Another option, which I went for in the end is using the --teamcity CLI parameter:
dotnetbuild --project:<path to project directory> -- --teamcity
which will integrate with TC's service messages. This will also do real-time updates.

I've installed NUnit Test Adapter for VS2012 + 2013. When I first installed the Adapter tests were showing up, but they stopped showing up for some reason today. After building, rebuilding, cleaning, restarting, nothing shows up in Test Explorer. Why would this be happening? I'm using VS2013 Ultimate.
If you're using a NUnit3+ version, there is a new Test Adapter available.
Go to "Tools -> Extensions and Updates -> Online" and search for "NUnit3 Test Adapter" and then install.
If your test project is set to target a 64bit platform, the tests won't show up in the NUnit Test Adapter.
My test assembly is 64-bit. From the menu bar at the top of visual studio 2012, I was able to select 'Test' -> 'Test Settings' -> 'Default Processor Architecture' -> 'X64'. After a 'Rebuild Solution' from the 'Build' menu, I was able to see all of my tests in test explorer. Hopefully this helps someone else in the future =D.
Check for NUnit versions mismatch. The currently available NUnit Test Adapter only works for NUnit version 2.6.4 and below.
To downgrade NUnit from version 3.x go to
Package Manager Console > update-package NUnit -version 2.6.4
http://jeremybytes.blogspot.co.ke/2015/11/review-of-unit-testing-makes-me-faster.html
In my situation the 'NUnit3 Test Adapter' has been disabled.
To re-enable it go to menu
Tools->Extensions and Updates...
On the left side select 'Installed'->'All'.
On the upper right corner search for 'nunit'.
If you have 'NUnit3 Test Adapter' installed, with the found item you can enable/disable it.
This answer seems pretty basic but wasn't completely obvious to me at first. If you (re)build the solution it only builds the projects that are configured to build in the Build -> Configuration Manager
This was my issue, I must have inadvertently changed a build configuration settings or something that caused my test projects not to build (when they previously were). So the Test Explorer window was looking at dlls that were out of date. It became clear to me this was the case after doing a Clean and seeing most of my tests disappear and not come back after a rebuild...further inspection of bin folder showed that these projects weren't being built at all.
I had a working setup (for NUnit2 and NUnit3 depending on the solution, and multiple versions of Visual Studio between 2012 and 2017), and it suddenly stopped working one day: no tests detected in any solution or version of VS.
In my case, it helped to delete %localappdata%\Temp\VisualStudioTestExplorerExtensions. After a restart of VS, everything worked as before.
If you are using VS 2017 and .net core ,as said here, you should add references to the test framework NUnit 3.6.1, to the test runner NUnit3TestAdapter 3.8.0-alpha1 and to the test SDK Microsoft.NET.Test.Sdk 15.0.0.

NUnitTestAdapter.WithFramework
Ctrl+R,A to build/run tests
Using NUnitTestAdapter.WithFramework makes sure there are little/no inconsistencies across versions of NUnit and NUnit Adapter (i.e. "it just works")
Check whether you have stated
[TestFixureSetUp]
and
[Test]
in the test class
sample:
namespace ClassLibrary1
{
public class SimpleCalculator
{
public Calculator _calculator;
[TestFixtureSetUp]
public void initialize()
{
_calculator = new Calculator();
}
[Test]
public void DivideTest()
{
int a = 10;
int b = 2;
int expectedValue = a/b;
int actualValue = _calculator.Divide(a, b);
Assert.AreEqual(expectedValue, actualValue, "Functionality not working properly!");
}
}
}
I had to uninstall then re-install the xunit.runner.visualstudio nuget package. I tried this after trying all the above suggestions, so may be it was a mixture of things.
One other cause to this problem is if you open a project from a mapped drive - Visual Studio handles such projects properly, but apparently Nunit doesn't support them.
Copying the project to a physical fixed the issue.
I also found that when I uninstalled nunit v3.2.1, the nunit framework reference for v3.2.1 was still in my project in solution explorer.
Solution Explorer > ProjectName > References
If you right click it will show the version. Remove this
Then Right click on References > Add Reference.
Search for the version 2.x version and add then rebuild solution.
That worked for me!
I experienced the problem mentioned by op
My case was that I was handed an old project and the tests were actually part of the system under test. I assume they were using the external test runner.
this task chain resolved the issue for me
created a test project,
moved the test files there
added references so the test project would compile
added the Nunit and Nunit adapter NuGet packages to the test project
recompiled
i was able to successfully run the Nunit tests.
If you are using the TestCaseSource attribute, ensure the source exists and respects the documentation, otherwise your tests will not be discovered.
I had a similar issue where the tests where not being discovered. I had the correct version of NUnit, versions matched up between NUnit and adapter, and the tests where tagged correctly. I was running VS 2017 Enterprise not as an administrator. After starting VS as administrator the tests appeared.
I started a new solution with a test project in it, and compared it against my original, problem project. The original, for some reason, had an app.config in it. I excluded that file from the project and saw my tests reappear in the test explorer.
I had this problem too but the cause was different. I'm using VS2017 with F# 4.0.
Firstly, the console in Visual Studio does not give you enough details why the tests could not be found; it will just fail to the load the DLL with the tests. So use NUnit3console.exe on the command line as this gives you more details.
In my case, it was because the test adapter was looking for a newer version of the F# Core DLL (4.4.1.0) (F# 4.1) whereas I'm still using 4.4.0.0 (F# 4.0). So I just added this to the app.config of the test project:-
<dependentAssembly>
<assemblyIdentity name="FSharp.Core" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="4.4.0.0" />
</dependentAssembly>
i.e. redirect to the earlier F# core.
I had the same problem, when suddenly any test didn't appeared on Test Explorer window.
I has the updated version of "NUnit3TestAdapter"
and after lots of searches and efforts,
I found that I need set the following values in project properties:
[In Solution Explorer window: right click on Project > Properties]
Under Build tab, set Platform=x64, and set Platform target=x86 or Any CPU
Build the project and all tests will be appear on Test Explorer window.
Important note:
I came to a solution after seeing the next msg in the output window:
"Test run will use DLL(s) built for framework Framework45 and platform X86. Following DLL(s) will not be part of run: AutomationTests.dll is built for Framework Framework45 and Platform X64."
I had some msbuild.exe processes that were hung. I don't know if that was my problem or not, but it took me a lot of trail and error with reinstalling various NUnit adaptors before I found the hung processes.
Just to add my $.02 here, I ran into a similar issue just yesterday, where 168 of my tests were missing. I tried most everything in this post - most especially making sure my version(s) of NUnit were the same - all to no avail. I then remembered that I had my tests divided into playlists; and these do not update automatically as you add new tests. So, when I deleted the playlists, BAM!, all of my tests were back once more.
I use NUnit 3 and tried most of the other solutions I saw here. None of those worked for me.
Even though already selected, reselecting the "Playlist: All Tests" option in test explorer showed all hidden tests in my case. I need to do this after every rebuild.
Make sure your test class is public. I often make this mistake then I just look at the code for 5 minutes what is going on.

NUnit3TestAdapter (NUnit 3 in my case ..)
After installation it should be possible to use the default TestExplorer included with the installation of Visual Studio.
If your test project is not x86, the tests will not be found until you tell the test runner the correct target platform.
Prior to Visual Studio 2022, this was the "Test/Test Settings/Default Processor Architecture" option.
In VS2022 you need to create a 'runsettings' file and set the test project to use it. In that file you can specify the Target Platform, like this:
<?xml version="1.0" encoding="utf-8" ?>
<RunSettings>
<!-- Configurations that affect the Test Framework -->
<RunConfiguration>
<TargetPlatform>x64</TargetPlatform>
</RunConfiguration>
</RunSettings>
You still also need to include the Nunit3TestAdapter and Microsoft.NET.Test.Sdk nugets (and make sure the project actually built, and check the various other more obscure mistakes mentioned in other answers)
Make sure your tests are properly marked with the Test attribute. If all of the tests are marked with only the Explicit attribute, the TestAdapter doesn't recognize the fixture.
I remember doing this in an older version of Team City in which the NUnit Runner failed, so I tried running NUnit using the Command Line Runner instead.
I think there was an option in the Command Line Runner settings which let you specify the kind of output file: NUnit result.xml was one of them. Doing this, you could see the test result breakdown in the Web GUI, just like when the NUnit Runner worked.
But I don't see this in the latest Team City (6.5.5). Can it still be done?
PS: Before anyone asks, I can't use Team City's NUnit Runner because NUnit has a bug which will be fixed in the soon to come 2.6.0 version. Said bug does not occurr when running nunit-console
This could be done using importdata TeamCity message, this is really helpful when you are running NUnit tests manually executing nunit-console.exe from an MSBuild script, for instance using NUnit MSBuild Community Task, but keep in mind that TeamCity provides built in NUnit tests runner so you do not need this low level TeamCity scripting. Anyway you can import report in this way:
<Message
Text="##teamcity[importData type='nunit' path='...\TestResults.xml']"
Importance="High"/>
See Importing XML Reports
If you prefer to run code coverage, code inspection, test tools or
duplicate finders directly from build script, not as a build runner,
you can use the importData service messages to import generated xml
reports into TeamCity.
The functionality was still there, found it by accident when looking at another build configuration. Importing an XML is now a "Build Feature", see:
