Azure devops not running MS test unit tests

Question

Ran into a strange issue with Azure Dev ops. I am trying to build my project in Azure Dev ops.

.Net Project structure looks like this in VS:

Solution
--src
--Test
----Test Proj. 1
----Test Proj. 2

And my azure-pipeline.yml looks like this:

trigger:
- main

pool:
  vmImage: 'windows-latest'

variables:
  solution: '**/*.sln'
  BuildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

steps:
- task: NuGetToolInstaller@1
- task: UseDotNet@2
  inputs:
    packageType: 'sdk'
    version: '3.1.x'
    includePreviewVersions: true
- task: DotNetCoreCLI@2
  displayName: Restore
  inputs:
    command: 'restore'
    projects: '**/*.sln'
    feedsToUse: 'config'
    nugetConfigPath: 'nuget.config'

- task: VSBuild@1
  inputs:
    solution: 'Project.sln'
    msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:DesktopBuildPackageLocation="$(build.artifactStagingDirectory)\WebApp.zip" /p:DeployIisAppPath="Default Web Site"'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'
    msbuildArchitecture: x64
- task: VSTest@2
  displayName: Test
  inputs:
    testAssemblyVer2: |
      **\*.UnitTest.dll
      !**\obj\**
    vsTestVersion: latest
    runSettingsFile: test\test.runsettings
    codeCoverageEnabled: true
    platform: $(BuildPlatform)
    configuration: $(BuildConfiguration)
    diagnosticsEnabled: true
    runInParallel: true

It is not able to find any test cases to run, and completes the step without running any test.

Is there something that I am missing here? or do I have to specify something else in the config?

My Test project.csproj file contains this:

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>

    <IsPackable>false</IsPackable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="CsvHelper" Version="18.0.0" />
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.7.1" />
    <PackageReference Include="MSTest.TestAdapter" Version="2.1.1" />
    <PackageReference Include="MSTest.TestFramework" Version="2.1.1" />
    <PackageReference Include="coverlet.collector" Version="1.3.0" />
  </ItemGroup>

For those seeing this thread whose problem is not due to the path being incorect: Check you have an appropriate test adapter for the framework you're using. In the above case it was MSTest so MSTest.TestAdapter nuget package would need to be installed in each test project

Azure devops not running MS test unit tests

According to your settings for Test files is:

  **\*.UnitTest.dll
  !**\obj\**

You should make sure that the name of your test project ends with .UnitTest, like Test.UnitTest, otherwise, the generate dll file should not be *.UnitTest.dll.

To resolve this issue, you could use test as a matching keyword(Make sure your test project name contains the test keyword):

**\*test*.dll
!**\*TestAdapter.dll
!**\obj\**

If above not help you, please try to share your test project name and the log of your test task.

Thanks Leo, my test projects name has "Tests" in the end, so it was getting skipped
