Visual Studio 2010 is not recognized Unit Test

Question

In an existing solution, I added a new test project. In my Project Project.cs file, I have a class decorated with the [TestClass] attribute and a method decorated with the [TestMethod] attribute. I checked that Configuration Manager has the build flag set for the test project (since my Google search was found, there was a problem for others with this problem). I set up a test project as my initial project for the solution. When I try to run a test, I get "I can not start a test project because the project does not contain any tests." I am really new to unit testing. What am I missing?

[TestClass] public class UnitTest1 { [TestMethod] public void TestMethod1() { Whole bunch of stuff Assert.Inconclusive("Done"); } } 

Update. So, I opened a new instance of VS, went to File => New => Project => Test Project. Do not touch or edit anything. I went directly to the cs file, and here is its entire contents:

 using Microsoft.VisualStudio.TestTools.UnitTesting; namespace TestProject2 { public class Inspection { public bool SubmitInsp() { return true; } } [TestClass] public class UnitTest1 { [TestMethod] public void TestMethod1() { Inspection insp = new Inspection(); bool result = insp.SubmitInsp(); Assert.IsTrue(result); } } } 

Same error about a project that does not contain any test when I try to run it. Also found this in the output of the assembly "Could not load file or assembly" ~ \ my documents \ visual studio 2010 \ Projects \ TestProject2 \ bin \ Debug \ TestProject2.dll or one of its dependencies. The operation is not supported. (Exception from HRESULT: 0x80131515) "

I do not know that unit tests become much simpler. What the hell???

Answer 1

In test projects saved in a network folder or anywhere locally on my computer, this problem occurs. I created another test project and saved it on my flash drive, it works fine. I don’t know if this is because my machine is 64-bit or because its virtual machine or something, but I think I just need to check everything on external storage devices.

I managed to get this to work by modifying the devenv.exe configuration file found here:

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe.config .

Add the following line to the <runtime> section, then restart Visual Studio:

 <loadFromRemoteSources enabled = "true" />

Answer 3

I had the same problem when tests in a working test project were suddenly not recognized.

Comparing the project file with one of the other working test projects showed me that the <ProjectTypeGuids> node was missing from the main <PropertyGroup> node.

Adding this line inside the <PropertyGroup> node solved my problem:

FROM#:

 <ProjectTypeGuids>{3AC096D0-A1C2-E12C-1390-A8335801FDAB};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids> 

VB:

 <ProjectTypeGuids>{3AC096D0-A1C2-E12C-1390-A8335801FDAB};{F184B08F-C81C-45F6-A57F-5ABD9991F28F}</ProjectTypeGuids> 

Answer 4

ansser FrstCBC did not work for me. I am on a VirtualBox machine with 64-bit versions of Windows 7 and Visual Studio 2012.

I had to move the output to a local folder : open the unit tests project properties, and on the Build tab, view the Output path . > to the local folder. Tests are now detected and can be run.

Answer 5

It was simple for me that my class and method were not public (I understand that the poster has public , but I found this post using Googling "testclate testmethod margin icons missing"). A stupid mistake on my part, but maybe this will help others.

Make sure that all .cs files are marked as Compilation in the Properties window. If it is marked as "Content", you will fall into this problem.
