Upgrading Microsoft.NET.Test.Sdk from 16.9.4 to 16.10.0: tests are ignored silently
Description
We have a pipeline in Azure DevOps which stopped running tests after we upgraded Microsoft.NET.Test.Sdk
to 16.10.0
.
Last running version seems to be: 16.9.4
Steps to reproduce
actual dotnet test command:
/opt/hostedtoolcache/dotnet/dotnet test /home/vsts/work/1/s/tests/Something.Tests/Something.Tests.csproj --logger trx --results-directory /home/vsts/work/_temp --no-build -c Release -s /home/vsts/work/1/s/CodeCoverage.runsettings /p:CollectCoverage=true /p:CoverletOutputFormat=opencover -- RunConfiguration.DisableAppDomain=true
Note: I noticed that running the command with --collect:"XPlat Code Coverage"
and removing /p:CollectCoverage=true /p:CoverletOutputFormat="opencover"
seems to work, but I need the latter since I need the reports.

Expected behavior
Starting test execution, please wait...
A total of 1 test files matched the specified pattern.

Actual behavior
The annoying thing is that it fails silently and we actually noticed this by mistake, we thought everything is fine since the job finishes successfully and without any errors.

Environment
Please share additional details about the test environment.
- Operating system
Azure Pipelines: ubuntu-18.04
- Build version of vstest.console
Microsoft (R) Test Execution Command Line Tool Version 16.8.0
- Package version of MSTest framework and adapter
- Other installed packages and their versions on the test project
Got around this for a bit by downgrading MSTest*
to 2.2.3
but it stopped working again recently.
At one point I randomly removed <Deterministic>false</Deterministic>
which fixed it briefly. Upgrading the packages broke it again and going back doesn't fix it anymore.
Visual Studio 2022 Preview 3.1 targeting dotnet 6 on preview 7.

@kiwimato were you getting any code coverage reports on 16.9.4 ?
@jakubch1 yes, actually downgrading Microsoft.NET.Test.Sdk
to 16.9.4
made code coverage work again.
Could you please paste output of command when using 16.9.4? Is the report opencover?
This is an example of working output. And yes it's an opencover report.

Thanks for info. In 16.10.0 we added support for dynamic code coverage in Linux. Unfortunately there is a bug in old version of TestPlatform which is causing this behaviour.
You have 2 options:
- Switch to dynamic code coverage. To do that you need to upgrade your dotnet version to latest stable and disable opencover (remove:
/p:CollectCoverage=true /p:CoverletOutputFormat=opencover
). This should give you better AzDo integration. If you upload your trx file to AzDo you will see coverage number in AzDo and even diff code coverage for PRs. - Continue using OpenCover and disable dynamic code coverage. To do that just remove your runsettings (your runsettings are enabling dynamic code coverage)
@jakubch1 @MarcoRossignoli Is this issue specifically related to mstest? It seems to be more of a Test Platform issue to me (in which case I will transfer it). Also, I think it can be closed.
@kiwimato is this issue still present?
Closing this issue. Feel free to ping if you have any other problem.
Thank you.
