Devops Pipeline refusing to run XUnit tests

Question

I have been really getting frustrated with getting unit tests to run in a Azure Devops Pipeline below is my YAML file contents

trigger:
- main

pool:
  vmImage: 'windows-2019'

variables:
  solution: '**/FestWise.stock*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'
  imageRepository: 'festwisestock'
  dotNetCoreVrs: '3.1.x'
  
steps:
- task: UseDotNet@2
  inputs:
    version: '$(dotNetCoreVrs)'
    packageType: 'sdk'


- task: NuGetCommand@2
  inputs:
    command: 'restore'
    restoreSolution: '**/FestWise.stock*.sln'
    feedsToUse: 'select'

- task: DotNetCoreCLI@2
  displayName: 'Restore project dependencies'
  inputs:
    command: 'restore'
    projects: '**/FestWise.Stock/FestWise.Stock.API/FestWise.StockService*.csproj'

- task: DotNetCoreCLI@2
  displayName: 'Build the project - $(buildConfiguration)'
  inputs:
    command: 'build'
    arguments: '--no-restore --configuration $(buildConfiguration)'
    projects: '**/FestWise.Stock/FestWise.Stock.API/FestWise.StockService*.csproj'

- task: DotNetCoreCLI@2
  displayName: 'Run unit tests - $(buildConfiguration)'
  inputs:
    command: 'test'
    arguments: '--no-build --configuration $(buildConfiguration)'
    publishTestResults: true
    projects: '**/*StockService.UnitTests.csproj'

the result is as follows:

Info: Azure Pipelines hosted agents have been updated and now contain .Net 5.x SDK/Runtime along with the older .Net Core version which are currently lts. Unless you have locked down a SDK version for your project(s), 5.x SDK might be picked up which might have breaking behavior as compared to previous versions.

Finishing: Run unit tests - Release

This is the furthest that i have come, it states it found the correct project but subsequently doesnt run any tests

Answer 1

So this was a drama to get figured out, for some reason it didnt want to find the build sln from the previous step and thus the --no-build argument made it not work

removing that argument solved it for me

new complete yaml (with some improvements to make it more variable dependent)

trigger:
- main

pool:
  vmImage: 'windows-2019'

variables:
  solution: '**/FestWise.stock*.sln'
  projectPath: '**/FestWise.Stock/FestWise.Stock.API/FestWise.StockService*.csproj'
  testProjectPath: '**/*/FestWise.StockService.UnitTests.csproj'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'
  dotNetCoreVrs: '3.1.x'
  
steps:
- task: UseDotNet@2
  inputs:
    version: '$(dotNetCoreVrs)'
    packageType: 'sdk'


- task: NuGetCommand@2
  inputs:
    command: 'restore'
    restoreSolution: $(solution)
    feedsToUse: 'select'

- task: DotNetCoreCLI@2
  displayName: 'Restore project dependencies'
  inputs:
    command: 'restore'
    projects: $(projectPath)

- task: DotNetCoreCLI@2
  displayName: 'Build the project - $(buildConfiguration)'
  inputs:
    command: 'build'
    arguments: '--no-restore --configuration $(buildConfiguration)'
    projects: $(projectPath)


- task: DotNetCoreCLI@2
  inputs:
      command: "test"
      includeNuGetOrg: true
      projects: $(testProjectPath)
      publishTestResults: true
