Testfx: Updating VS 2017 to 15.4.5 stopped discovering MsTest 1.2 tests

Description

Today I upgraded VS 2017 to 15.4.5 and it stopped discovering any tests in any of my projects/solutions.

Actual behavior

Can you turn on the following diagnostic logs and share them here please:

1. In VS, go to Tools-> Options-> Test-> Logging.Set the logging level to "Diagnostics" and clean build your solution. Logs would show up in Output -> Tests pane in VS.
2. Set TPTrace to 4 in %ProgramFilesx86%\Microsoft Visual Studio\2017\Enterprise\Comon7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.discoveryengine*.exe.config. Logs for this would go to %temp%. Refer this blog post here.

Let me try. Small addition: it's %ProgramFiles(x86).

also experiencing this, created an out of the box unit test project and can't discover tests.

[12/4/2017 16:26:38 Error] c:\Temp\VisualStudioTestExplorerExtensions\MSTest.TestAdapter.1.2.0/build/_common/Microsoft.VisualStudio.TestPlatform.MSTest.TestAdapter.dll
This seems to be an issue with adapter dll not getting loaded from appropriate location.

@abatishchev, @twilly86 : Can you guys try deleting this folder "c:\Temp\VisualStudioTestExplorerExtensions", restart VS and do discovery again?
If this still doesn't work, can you also try deleting "/packages" folder(containing all nuget packages required for that solution) which is created at solution level.

[abatishchev]

For me it has self-fixed but I cleared %temp% at some point of time

[jayaranigarg]

We are glad to hear that the issue got fixed. Please feel free to reopen this thread if you still face any problem.

Experiencing the same issue while running the mstest from command line.
mstest.exe /testcontainer:abc.dll

Says:

Clearing %temp% & package directory doesn't work for me.

[jayaranigarg]

@santoshaher11 : Running MSTestV2 tests is not supported with mstest.exe. Please use vstest.console.exe to run MSTestV2 based tests.

[TheFanatr]

I seem to be having the same error even though MSTest is still finding my tests; some of them are simply failing for no reason, then the inner exception says System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.TestPlatform.Utilities, Version=15.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.. Is this a separate issue, or does it have something to do with my code? The outer exception says that a type initializer for one of my classes threw an exception; this seems misleading because it basically implies that my type initializer failed because it was trying to access Microsoft.TestPlatform.Utilities, though I know for a fact that it doesn't even touch anything to do with unit testing.
Full test result:
Message: Test method Test1.DecoderTests.TestDecodeDate threw exception: System.TypeInitializationException: The type initializer for 'Decoder.Client' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.TestPlatform.Utilities, Version=15.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

[jayaranigarg]

@TheFanatr : What is the target framework for your project (net46/netcore)? What are the versions of nuget packages that you are using? If possible, can you share a repro project with us?

Also, please provide us diagnostics logs for your scenario. This doc should help.

[abatishchev]

Should we reopen the issue since more people are coming with having it? Thanks.

[jreusseradesa]

I recently upgraded to MSTest 2.0 on a fresh install of VS2017.
Am experiencing same issue as OP.

[jacksondaw]

I am experiencing the same issue.

I took a look at the error and the stack trace, neither provided much information, but the fusion log seems to give a little more detail of where the error is occurring. If you still need a repro, let me know

[DouglasMarsh]

I'm running VS 2017 Pro 15.5.6. Same issue.

Test discovery is completely broken.
Based on diagnostic logs. The test runners are failing to load.
This is both from VS and using dotnet test

Microsoft.VisualStudio.TestPlatform.MSTest.TestAdapter: Failed to load assembly. Reason:System.BadImageFormatException

xunit.runner.visualstudio.dotnetcore.testadapter: Failed to load assembly. Reason:System.BadImageFormatException

I can get xunit test to run from command-line using:
dotnet xunit --fxversion 2.0.5
Or by specifying RuntimeVersion in the csproj.

[jacksondaw]

I have been ignoring this issue for the past couple weeks, because I figured out if I run the tests without debugging from the test explorer they execute without any issues. Just this morning, I was able to resolve the issue for myself by closing Visual Studio, deleting both the .vs directory and the TestResults directory, then reopening VS. Stupidly, I did them both at the same time, so I cannot tell you which one actually fixed the issue.

Also, I just opened Douglas Marshall's project and when trying to run the original tests it said "No test is available in ..."

In an attempt to debug the issue, I added a new test project both regular MSTest and .Net Core and added a test and they both worked normally. So I went back into the .csproj file for UnitTestProject and xUnitProject and changed it to match a newly created project and it worked without any issues. The RuntimeFrameworkVersion element seems to be the culprit, for my setup.

Remove:

<RuntimeFrameworkVersion>2.0.5</RuntimeFrameworkVersion>

Let me know if either one of these "fixes" is unclear?

[DouglasMarsh]

Your fix didn't work for me.
however I have isolated it to .Net Core Unit Tests.
A Full Framework test executes with no issues.

I initially started with a OTB unit test template and added RuntimeFrameworkVersion was based on the workaround documented in issue https://github.com/xunit/xunit/issues/1573

[abatishchev]

My tests are on full .net only

[jayaranigarg]

@DouglasMarsh : We apologize for the inconvenience. Thank you for sharing repro project with us. However, we are able to run tests just fine and the issue is not reproing for us.
Can you please share following information with us:

1. Go to C:\Program Files\dotnet\shared\Microsoft.NETCore.App and share with us which all versions of dotnet is installed on your machine?
2. In VS, go to Tools->options->Projects and Solutions->Build and run, and change MSBuild project build output verbosity to "Diagnostics" and share the logs appearing in "Build" window with us?
3. Build your project from command line with diag switch enabled i.e. dotnet test -d "LogFile.txt" and share this log file with us?

[DouglasMarsh]

dotnet versions: 1.05, 1.1.2, 2.0.0, 2.0.3, 2.0.5

[ebol2000]

We had a similar problem that we were able to fix.

Scenario
We had a solution with multiple version of the framework, namely 1.1.11 and 1.1.18 in use by two distinct unit test projects.

Resolution
Once I had upgraded both to use the same version (the 1.1.18) then my tests started becoming visible again.

Problem
There appears to be a conflict somewhere when VS is referencing the two versions within the same solution. This is just my theory based on the observed behavior. Perhaps someone could investigate a potential compatibility issue. If true, the behavior of VS always pulling in the latest version from NuGet regardless of what other versions are already being referenced within the solution will only spread this problem. On the other hand, perhaps this is only a collision of specific versions of MSTest.

[cltshivash]

@abatishchev Could you please confirm if the issue is present post update to 15.6.2 and using the same adapater version in your solution ?

[abatishchev]

@cltshivash unfortunately I cannot. I switched team and now fighting with CloudBuild to recognize MsTest from NuGet rather then use the built-in. You can imagine :)

[ShreyasRmsft]

Was able to repro this issue with VS 15.6.3 and MsTest versions 1.2.0 and 1.3.0 used by 2 projects in the same solution

[joanjane]

Same here with VS 15.6.4. Removed AppData/Local/Temp/VisualStudioTestExplorerExtensions folder and worked fine again. The original folder VisualStudioTestExplorerExtensions/MSTest.TestAdapter.1.2.0/bin/_common was empty, instead I had another folder with expected files VisualStudioTestExplorerExtensions/1.2.0/bin/_common.

Hope it helps!

[spottedmahn]

VS 15.6.6, same results as @joanjane.

I closed VS, delete VisualStudioTestExplorerExtensions and then it started to work again.

Developer Community Issue

[spottedmahn]

Supposedly fixed in 15.7 preview 4. Source.

[jayaranigarg]

Closing the issue for now. Please feel free to re-open if you hit this again after updating to 15.7 Preview 4 and above.

[MohammadHazara]

@abatishchev
I am also having trouble running test script on CloudBuild. Did you solved your problem and how?

[abatishchev]

@MohammadHazara CloudBuild? The only system I know of this name is Microsoft internal. Are you working for Microsoft?
