Unsupported test framework error in NUnit
I am using NUnit testing with Visual Studio 2013. We are using NUnitTestAdapter for integration of test run of NUnit with Visual Studio.
Visual Studio 2013 NUnit is version="3.0.1" NUnitTestAdapter version="2.0.0" .Net Framework 4.5.2
All packages are latest & installed from Nuget. There is no build error. We are getting error in test result window:
Attempt to load assembly with unsupported test framework in D:\JuniorAchievement\Git\jaums\JA.UMS.Tests\bin\Debug\JA.UMS.Tests.dll
while running or debugging test using Visual Studio Test Explorer.
Test is able to run on one machine with same code on Visual Studio 2013 ultimate. We all other have Visual Studio 2013 professional version, although I doubt it has nothing to do with the problem.
Please Help.
Update
__________
After update to NUnit3 Test Adapter no error but still no test are discovered.
Somehow both Adapter are available but with Nuget & VS extension I can find only NUnit3 Test Adapter.
Installed NUnit3 Test Adapter from https://visualstudiogallery.msdn.microsoft.com/0da0f6bd-9bb6-4ae3-87a8-537788622f2d
Answer
It looks like you are trying to run NUnit3 tests with the NUnit2 Test Adapter. This is not supported.
You need to install the NUnit3 Test Adapter through Tools > Extensions and Updates in Visual Studio.
