VS2022 - JustMock ThrowElevatedMockingException with .Net 6

Hi,

I am trying to run the unit test for my .net 6 and want to see the code coverage using "Analyse Code Coverage for all Tests" in VS2022.

it successfully run all all test cases when I "run all Tests" but when I use "Analyse Code Coverage for all Tests" to run and see the code coverage, there are some test case failed throwing ThrowElevatedMockingException as below.

 Message: 
Telerik.JustMock.Core.ElevatedMockingException : Cannot mock 'System.Threading.Tasks.Task`1[System.Collections.Generic.List`1[AppHub.SingleView.AmazonFireStickPromo.Models.AccountPromoToken]] GetAccountPromoTokensAsync(System.String)'. The profiler must be enabled to mock, arrange or execute the specified target.
Detected active third-party profilers:
* {324F817A-7420-4E6D-B3C1-143FBED6D855} (from process environment)
Disable the profilers or link them from the JustMock configuration utility. Restart the test runner and, if necessary, Visual Studio after linking.

  Stack Trace:

I think run all test is successful as I use specify env.runsettings in my project file (attached file).

but the test run in "Analyse Code Coverage for all Tests" failed in some methods.

Package I used

    <PackageReference Include="JustMock.Commercial" Version="2023.1.117.1" />

Can someone help me to fix this one ?

Thanks

JustMock Profiler on Linux - Profiler not enabled

Hi there

We are trying to move our current build agents from Windows to Linux (Ubuntu 20.04) for all our dotnet6.0 applications and trying to integrate the JustMock Profiler on this machine because we depend on it in several tests.

Therefore, we followed your integration article "JustMock Integration on Linux".

We have copied the Profiler binaries to the build agent and referencing it through the environment variable:

root@8d248b92b005:/azp/Backend# printenv | grep 'CORE\|JUST'
CORECLR_PROFILER_PATH=/opt/TelerikJustMock/JustMock_2022_1_223_1_Dev/Libraries/CodeWeaver/64/libTelerik.CodeWeaver.Profiler.so
CORECLR_PROFILER={B7ABE522-A68F-44F2-925B-81E7488E9EC0}
JUSTMOCK_INSTANCE=1
CORECLR_ENABLE_PROFILING=1

The csproj definition for referencing the JustMock library looks (at the moment) like the following:

...
<ItemGroup>
    <Reference Include="Telerik.JustMock">
        <HintPath Condition="Exists('C:\Program Files (x86)\Progress\Telerik JustMock\Libraries\netcoreapp2.0\Telerik.JustMock.dll')">C:\Program Files (x86)\Progress\Telerik JustMock\Libraries\netcoreapp2.0\Telerik.JustMock.dll</HintPath>
        <HintPath Condition="Exists('/opt/TelerikJustMock/JustMock_2022_1_223_1_Dev/Libraries/netcoreapp2.0/Telerik.JustMock.dll')">/opt/TelerikJustMock/JustMock_2022_1_223_1_Dev/Libraries/netcoreapp2.0/Telerik.JustMock.dll</HintPath>
        <Private>True</Private>
    </Reference>
</ItemGroup>
...

In the tests we are calling the following method to check for the Profiler to be enabled:

public class Test_JustMockProfiler_Enabled
{
	[Fact]
	public void ProfilerMustBeEnabled()
	{
		Mock.IsProfilerEnabled.Should().BeTrue();
	}
}

Then running the tests with the 'dotnet test' command:

dotnet test /path/to/Tests.dll --no-build --no-restore -l:trx --results-directory ./TestResults/

But still we get the following error:

Error Message:
   Expected Mock.IsProfilerEnabled to be true, but found False.

Installed dotnet:

root@8d248b92b005:/azp/Backend# dotnet --info

Is there anything we are missing or doing wrong?
How do we properly enable the Profile on Linux to run in 'dotnet test'?

Thanks for your help in advance, cheers.

Exception "The profiler must be enabled to mock, arrange or execute the specified target."

Hi there

We are facing an issue on our on-premise Azure DevOps build agents, where we have JustMock installed, since the version 2.0.13 from last Thursday 6th Oct. 2022 but also with the today's version 2.0.14.

Exception:

[xUnit.net 00:00:02.79]       Telerik.JustMock.Core.ElevatedMockingException : Cannot mock 'System.DateTime'. The profiler must be enabled to mock, arrange or execute the specified target.

[xUnit.net 00:00:02.79]            at Telerik.JustMock.Mock.Arrange[TResult](Expression`1 expression)

We are using the task JustMockVSTest@2 and have no additional configurations for the JustMock Profiler set, like described in your integration guide: https://docs.telerik.com/devtools/justmock/integration/continuous-integration/tfs-azure/azure-devops

On the system there is the Profiler installed under "C:\Program Files (x86)\Progress\Telerik JustMock\Libraries\CodeWeaver\<bitness>\Telerik.CodeWeaver.Profiler.dll"

We see that the task is initializing the path to the Profiler (32bit and 64bit) to the $(System.DefaultWorkingDirectory) like:

Starting: VsTest - testAssemblies
==============================================================================
Task         : Telerik JustMock VSTest v.2
Description  : Use VSTest runner to run tests that are mocked with Telerik JustMock.
Version      : 2.7.1

==============================================================================

The specified path to 64 bit JustMock profiler is: D:\azagent\<organisation>\A1\_work\<build>\s

Running tests using vstest.console.exe runner.
======================================================

Before the Profiler was initialized with null:

Starting: VsTest - testAssemblies
==============================================================================
Task         : Telerik JustMock VSTest v.2
Description  : Use VSTest runner to run tests that are mocked with Telerik JustMock.

==============================================================================

======================================================
The specified path to 32 bit JustMock profiler is: null
The specified path to 64 bit JustMock profiler is: null
SystemVssConnection exists true
Running tests using vstest.console.exe runner.
======================================================

Is there anything we have to configure, like the absolute/relative path to the Profiler? Or is this a bug within the new release?

Thanks for your help.

Cheers

Hide hints like JMA001 in VS

In Visual Studio 2022, the first quick action is often "Create Mock". As this is used in the overlay when hovering over a method, I see "JMA001" quite often, which is not helpful when writing non-test code.

I know that I could create a .editorconfig file to suppress individual hints for every project I work on, but how can I prevent the JustMock hints from being used in the quick actions completely across projects?

System.InvalidProgramException : Common Language Runtime detected an invalid program. (justMock + xUnit + dotCover)

Hi Team

We tried executing justMock test cases in command prompt using justMock Console (licensed), dotCover and xUnit, but justMock Test execution failed and gave the error "System.InvalidProgramException : Common Language Runtime detected an invalid program."

The command we use to execute is as follows:

start /wait "" "{PATH}\JustMock\Libraries\Telerik.JustMock.Configuration.exe" /link "dotCover"

"{PATH}\JustMock\Libraries\Telerik.JustMock.Console.exe" runadvanced --profiler-path-64 "{PATH}\JustMock\Libraries\CodeWeaver\64\Telerik.CodeWeaver.Profiler.dll" --command "{PATH}\JetBrains.dotCover.CommandLineTools.2021.1.3\dotCover.exe" --command-args "cover --reporttype=html --output=CodeCoverage\\index.html --targetexecutable=\"{PATH}\xunit.runner.console.2.4.1\tools\net472\xunit.console.exe\" -- \"{PATH}\{PATH_OF_JUSTMOCK_TEST_DLL}\""

start /wait "" "{PATH}\JustMock\Libraries\Telerik.JustMock.Configuration.exe" /unlink "dotCover"

Attaching the log and test code.
