How to fail the build pipeline if "Tests Failed" in azure pipelines? - azure-devops

Question

I want to fail the build pipeline if a single test failed with azure pipelines.
Azure can successfully detect that my tests entered a failed state however it gives a success state to the entire build pipeline:
The question is how to make azure give a failed build state if the tests stage failed?
Here's my azure-pipelines.yml :
# Build ASP.NET Core project using Azure Pipelines
# https://learn.microsoft.com/azure/devops/pipelines/languages/dotnet-core?view=vsts
pool:
vmImage: 'Ubuntu 16.04'
variables:
buildConfiguration: 'Release'
steps:
- script: |
dotnet build --configuration $(buildConfiguration)
dotnet test dotnetcore-tests --configuration $(buildConfiguration) --logger trx
dotnet publish --configuration $(buildConfiguration) --output $BUILD_ARTIFACTSTAGINGDIRECTORY
- task: PublishTestResults#2
inputs:
testRunner: VSTest
testResultsFiles: '**/*.trx'
- task: PublishBuildArtifacts#1

Answer 1

The original answer didn't work for me, but it looks like there was a lot of discussion on this, and there's now a failTaskOnFailedTests param for the task. That seems to work.
- task: PublishTestResults#2
inputs:
testRunner: VSTest
testResultsFiles: '**/*.trx'
failTaskOnFailedTests: true
I'm still surprised this wasn't default behavior.

Answer 2

Try to add failOnStandardError: 'true' in the task inputs:
- task: PublishTestResults#2
inputs:
testRunner: VSTest
testResultsFiles: '**/*.trx'
failOnStandardError: 'true'
