I am just starting to work with QuantLib project. There are quite a few BOOST unit tests defined, hence the question: is there an easy way to run these tests selectively from Visual Studio (and see results)?
I've only used unit testing in .Net languages so far, and there you can either use the built-in test runner if you use MsTest, or some add-on (I used Resharper and TestDriven.NET) for other frameworks. There you can choose which tests you run, and you can run them with the debugger attached (which is unfortunately useful sometimes). Are there similar add-ons for BOOST tests in unmanaged C++?
Yes you can!
If your boost unit test project is defined correctly, then you can run the entire test project from VS10 debugger by clicking
right click on project --> Debug --> Start new instance
This will run the tests inside VS framework which will give you all the debugger goodies.
For running specific test suites/cases, just edit the project command line arguments under
right click on project --> Properties --> General --> Debugging
and add the parameters according to the links in the other answers
you can run any test case or test suite via command line. running tests by name
it even allows wildcards.
ReSharper C++ supports discovery and selective running/debugging of Boost tests (with Boost 1.59 and later).
I'm using the Boost Unit Test Adapter. It's free and has a very nice output. It can also list the time the single tests consumed and you can start single tests and group of tests.
You can download it here:

I have a Windows 8 Store App with two projects within the solution - one project exclusively for tests. I have added NUnit and NUnit Test Adapter (https://www.nuget.org/packages/NUnitTestAdapter/1.0.0) for this through nuget.
My tests are detected - but I cannot run or debug them. Looking at the test output window, I get the following error:
Could not find test executor with URI 'executor://nunittestexecutor/'. Make sure that the test executor is installed and supports .net runtime version 4.0.30319.34003.
I am not using resharper and I am using Visual Studio Professional 2012 Update 3 on Windows 8.1. References for the test project are as follows:
Based on my comments above, below is a workaround. Unfortunately at this stage, Windows 8.1 store Unit Test project types, using NUnit extension wouldn't work due to the different .NET targets. I tried with different Test Unit Adapters including an NUnitTestAdapterWithFramework.
It seems that the issue you haveing was occurring with standard .NET libraries targeting NUnit test adapter but the above NUnitTestAdapterWithFramework must have fixed those issue. See the Q & A section of the NUnitTestExtension
But unfortunatly it seems that this still of an issue that hasn't been fixed for Win8 Store App type Unit Testing. Pretty sure xUnit.NET also not compatible yet with different .NET target types (i,e WinRT)
So what are the options?
a. For your group, you can change them to use MSTest framework. Outcome - Problem Solved no issues.
b. Workaround "linked project". Outcome - Can't *guarantee** but this should also work.
With option 'b'
In your comment you mentioned.
but I'm still not sure what it does or how to implement a 'linked
project', do you have any more information on this? Also, as this is
for a group university project, I was hoping i wouldn't have to force
too many workarounds
When you think about it, it is not really hard work around. It is simple and I'm sure your group would be able to apply this workaround easily.
Please follow the below steps.
Create a separate class library in your solution (you can target .NET framework 4).
Then add NUnit assemblies and the NUnit test adapter as usual.
Right click on this project and select 'Add' then 'Existing Item'
Select the Win8 Store Unit Test project and locate the Unit Test file you want to add. When you add the file, make sure you select 'Add As a Link' button. Please see below.
Now rebuild the solution, close and re-open the UnitTest explorer and you should be able to run those tests.
*The reason I said can't guaranteed. I haven't really written Unit tests against Win8 App. So if your SUT (System Under Test) require special configuration it might cause issues. But I'm not sure.
Finally creating a link files are not that hard if everything works you can continue to do this until NUnit has the support for Win8 Unit Testing. Or the other option is simply change all your Unit Tests to use MSTest framework if possible.
In our solution we have several test projects. Most of them contain unit tests that run fast but some are for integration, acceptance and UI tests which take quite some time to finish.
Now I'd like to have a convenient way of running only the unit tests. Either by using the hotkey to run all or using the new feature to run tests after each build.
Unfortunately VS also runs all the slow tests as well. In VS10 I grouped the tests in Test View by project and selected only the ones containing unit tests. It's not as easy as I wished it to be but at least it was possible. Now there doesn't seem to be a way around running all tests in a solution.
The only alternative that I see at the moment is to remove all but the unit tests from the solution but this would limit the refactoring capabilities.
So does anyone know how to easily group and run only unit tests in the new VS?
In Visual Studio 2012 Update 1 CTP, Test Explorer has added the option to group tests by Project or Traits (Categories).
Please go to this link to see what's new there.
You can use the search filter in Unit Text Explorer.
In the new Test Exlorer shipped with 2012, you can group tests by 'Test Results', 'FileName',... etc but in RTM build group/search by 'TestCategory' is not present from Test Explorer. However there is a filter in commandline and TeamBuild based on TestCategory (Running selective unit tests in VS 2012 RC using TestCaseFilter) in VS2012.
From a member of VS dev Team, they understood the importance of this missing feature. It is in the backlog, and it should be available in furutre builds/updates.
The following blog provides more details: http://blogs.msdn.com/b/vikramagrawal/archive/2012/07/23/running-selective-unit-tests-in-vs-2012-rc-using-testcasefilter.aspx
As of Visual Studio 2012 Update 2 (currently on CTP) now we are able to run a subset of unit test using "Playlists" or based on "Lists & Classes". More information here: http://blogs.msdn.com/b/visualstudioalm/archive/2013/01/30/first-ctp-for-visual-studio-update-2.aspx#playlists
Original Answer:
AFAIK, The new unit testing framework in VS2012 "supports selective execution based on filtering condition through TestCaseFilter". Unfortunately, currently there is not support to do this through the user interface but it is in the product group's backlog. You can use this approach through Test Build or command line. Please refer to the following blog: http://blogs.msdn.com/b/vikramagrawal/archive/2012/07/23/running-selective-unit-tests-in-vs-2012-rc-using-testcasefilter.aspx
EDIT: Following the MSDN documentation to use test categories to group tests.
http://msdn.microsoft.com/en-us/library/dd286595.aspx
Also, refer to this question: How to exclude certain tests in the Visual Studio 2012 Test Runner?
It shows an example of filtering based on the test path.
I'd recommend using TestDriven.Net. Group all Unit Testing projects in one solution folder, and all other tests in another. Then just right click the "Unit Tests" folder and choose "Run All Tests". I always favor this great test runner of the VS native testing tools.
Another approach is using NCrunch - It runs all you tests in the background while you code. It handles integration tests pretty well, as they run in parallel, in the background so it doesn't block you (you also choose which test projects are run). One catch though - I believe it doesn't support VS2012 yet, but probably soon.
I was also missing this feature... (We did the same as you did: grouping by project or sometimes by namespace). But I found that I could somehow workaround this using the test explorer search capabilities:
https://msmvps.com/blogs/deborahk/archive/2012/09/16/searching-and-grouping-in-vs-2012-test-explorer.aspx
In my case I could identify the specific tests I needed to run using the search filter on FullName (use dropdown on search box, or type FullName:"UnitTest")
Its not the same, but it works for me
We're using JIRA with Bamboo as build server for continuous integration.
But I have a native C++ project (using Visual Studio 2010), and apparently Microsoft doesn't support unit tests for native C++ code. There's some tools like WinUnit or cfix that seem to do the job, but neither do I know about their compatibility to Bamboo, nor do I know which tool is the best / easiest to use / has the most features / has best VS compatibility ...
Does someone have experience with that?
Just as a heads up, my current project is using c++ with bamboo for CI. We use googletest for our testing framework. If you have the build run with --gtest_output=xml:{file or Directory} it will produce xml output that can parsed by Bamboo's JUnit Parse task.
I played a bit with CppUnit. The way it works is that you create an executable project which you fill with your test cases. When run, it runs your tests. I think cfix does that but I've never used it for user mode testing. To run the tests as part of your build process, put in a post build step for your test project that runs the test exe. It'll run when you build your Visual Studio solution.
I have 80+ VS2010 solutions, each contains some unit test projects.
All solutions are merged into one big solution before build process.
All tests (or some test subset) are executed after the successful build.
I want to enable test code coverage for all tests to get exact code coverage for all output assemblies.
My question is: how to enable code coverage without using Visual Studio?
Note: I'm using TFS2010 (MSBuild) to build merged solution. VS 2010 Premium is installed on the build server. MSTest is used for test execution.
You can use JetBrain's TeamCity Professional. It is a CI server that supports executing unit tests and calculating code coverage. It is free for small installations.
I think you need to consider deploying a code coverage tool, see here for a comparison (provided you implement .net).We use NCover, which integrated in our TFS-Build in it's console variant and, although it's not trivial to set it up, we 're very satisfied with it.In this post I had briefly described how we inserted NCoverin our build, this might we useful to you even if you go with another tool.
If you create a Vsmdi file in your large solution (ms test will usually do this for you) you can use this to tell the build which assemblies you want to instrument.
This will only provide code coverage for assemblies that have tests run against them. If you're using testrun.config files to decide which tests you want to run, this should be all you need. The code coverage results should then be published to the build drop location
Edit:
This blog post looks like it covers setting up code coverage
From reasons I won't get into, all our unit tests are using the VSTS test framework. I now want to create an MSBuild script that runs the tests, but I don't want to use mstest.exe from various reasons (it's slower, requires Visual Studio installation everywhere, I need to maintain testrunconfig, etc.)
I've seen that TestDriven.net and TeamCity are able to run VSTS tests 'NUnit style', without using mstest.exe. Are you aware of any standalone command line utility that does this?
You can execute Team System Tests (MSTest) in NUnit if you use a special NUnit Addin that recognizes the MS Test Attributes (TestClass, etc).
Exact Magic Software has an open-source "test-adapter" that can do this.
UPDATE: I've reworked Exact Magic's Msts NUnit Adapter for NUnit 2.5.2.
Download here: http://snippetware.googlecode.com/files/ExactMagic.MstsAdapter.zip
Read more about it here: http://www.bryancook.net/2009/10/mstest-nunit-adapter.html
It seems like TeamCity is simply leveraging Gallio to run VS tests. Gallio appears to have msbuild integration and sounds perfect but after a closer look it seems that it would require a VS install just like MSTest as it appears to depend on MS exes:
The plugin enable condition was not satisfied: '${process:DEVENV.EXE} or
${process:VSTESTHOST.EXE} or
${process:QTAGENT.EXE} or
${process:QTAGENT32.EXE} or
${process:QTDCAGENT.EXE} or
${process:QTDCAGENT32.EXE}'.
Host process exited with code: 0
That being said it sounds like at least one person has got it working:
Christoph De Baene - Running MSTest without Visual Studio
It is possible to run MSTests without installing Visual Studio. See how-do-i-use-mstest-without-visual-studio.
I did this so that I could run my tests as part of my CI process. (I am using CC.NET for my CI solution).
I am in a similar situation as you, in that I want to use TestDriven.NET to get code coverage stats. But, I am running into problems. My first problem is that I am using AssemblyInitialize attributes to initialize a database connection. This isn't supported by NUnit so about half of my tests fail whereas they run fine under MSTest.
So, it seems that translating tests from one test framework to another has pitfalls. If you are aware of that, then go forth, but it might be better to try and keep consistent on one test framework.
We run VSTS tests using msbuild TestToolsTask on a Cruise Control server. This does not use the MSTEST executable -- the condition you ask for -- but does use a variety of TFS dependencies.
Note that we are migrating tests off of the VSTS test framework for NUnit, mostly because we can create extensions for NUnit to perform useful tasks.
