Error: The profiler must be enabled (but it is !)

[Francis]

Visual Studio Professional 2019 - version 16.6.3

JustMock 2019.1.115.2 (Commercial version)

My solution has 3000+ unit tests and suddenly, 1000+ tests failed with the error :

 Message: 
    Test method Cloee2.Ws.UnitTests.Services.Business.TestConditionsAdmissionSe2.GetClasseGeneriqueNulle threw exception: 
    Telerik.JustMock.Core.ElevatedMockingException: Cannot mock 'Ch.Ne.Ceg.Cloee2.Services.CrudCloee2Helper'. The profiler must be enabled to mock, arrange or execute the specified target.
  Stack Trace: 
    ProfilerInterceptor.ThrowElevatedMockingException(MemberInfo member)
    MocksRepository.InterceptStatics(Type type, MockCreationSettings settings, Boolean mockStaticConstructor)

    TestConditionsAdmissionSe2._arrangeSearchFormations() line 523
    TestConditionsAdmissionSe2._mockGetClasseGenerique() line 913
    TestConditionsAdmissionSe2.GetClasseGeneriqueNulle() line 987

They pass in debug, but not in run.

I try to clear bin and obj folder of my solution, but nothing to do.

Any idea ?

I upgrade JustMock to version 2020.1.616.2 and the problem is gone.

I'm having this same issue now, but am on 2023.2.719.137 using VS 2022. Profiler is enabled in IDE, IsProfilerEnabled is true when debugging tests, but false when running tests normally. Is there a similar problem with this release?

[Ivo]

No there is no such known issue, please try to get the output of the following helper:

private static string GetEnvironmentEntries()
{
    var varEntries =
        Environment.GetEnvironmentVariables()
            .OfType<DictionaryEntry>()
            .Where(entry => entry.Key.ToString().StartsWith("COR_") || entry.Key.ToString().StartsWith("CORECLR_") || entry.Key.ToString().StartsWith("JUSTMOCK_"))
            .Select(entry => string.Format("{0} = {1}", entry.Key, entry.Value))
            .ToList();
    return string.Join(Environment.NewLine, varEntries.OrderBy(e => e));
}

Hello,

I have the same problem.

IDE: vs 2022

Version: 2025-1.211.365

- I've completely uninstalled and reinstalled without success, still the same problem.

[Ivo]

Aek, could you please provide an output as shown above? You need to add the code to one of your tests and debug trace the returned string.

[Aek]

Hello,
I no longer have the error mentioned after adding these two environment settings:
CORECLR_ENABLE_PROFILING 1
CORECLR_PROFILER {B7ABE522-A68F-44F2-925B-81E7488E9EC0}

When I ran the code above for the first time, I only had the JUSTMOCK_INSTANCE parameter.

Thank you very much!

[Ivo]

I am happy to hear that, Aek!
