visual-studio unit-testing

Solution 1:^[1]

In Nunit, if there is an exception in loading test setup or execution it will result in above. From Visual studio menu open debug=>output and select Test window and see are there any exceptions thrown when tests are run. In my case in project1 i have nunit2 (refernce), in project2 i have nunit3 which referred project1 which is causing conflict and unable to execute.

if you resolve the exception it should work

Check if you have runsettings file in your solution or if there is one selected under VS -> Test -> Configure Run Settings. If this is chosen, uncheck it. Remove the file. This fixed for me.

Solution 3:^[3]

In Case anyone is still struggling with this, installing "MSTest.TestAdapter" solved my issue.

Solution 4:^[4]

For me a simple "Clean Solution" worked.

Solution 5:^[5]

Ensure the access modifier of the class is public instead of internal. If it is internal none of the [Fact]s in the class will register as tests within the Test Explorer, nor will they run.

Solution 6:^[6]

Here in my case the issue was different . In VS Unit tests are being identified based on Test class. In my case , there were no access modifier for the class and which caused the issue .VS unable to identify the test methods for the particular class.

 class ControllerTests
{    
    public Controller _Controller;
   
    [TestMethod()]
}

After adding public to the class ,it worked fine. Public class ControllerTests {
public Controller _Controller;

    [TestMethod()]
}

Solution 7:^[7]

Installing Microsoft.NET.Test.Sdk package from nuget package manager solved my issue. I also have xunit and xunit.runner.visualstudio package installed.
