I have one task in my CI that has failOnStandardError: true so when VSTest run any test that does not pass, and write standard error, I got error on CI and my pipeline is stop

My question is how to enforce test runner redirect standard error output to standard normal output?

thanks

Where have you set failOnStandardError. Can you please provide a sample which shows what you try to achieve.

I have azure-pipeline yaml file like below

stages:
- stage: Build
  displayName: 'Build Stage'
  jobs:
  - job: Build_Windows
    displayName: 'Build .Net framework on Windows'
    workspace:
      clean: all
    steps:
    - task: BatchScript@1
      inputs:
        filename: 'Hooshang/sbuild.bat'
        arguments: '--vrebosity=diagnostic'
        workingFolder: 'Hooshang'
        failOnStandardError: true

And I got

Because VSTest says

You can use StartProcess alias to run your test runner where you can pass settings to redirect standard error.

I use VSTest dsl in cake, so I don't know a way to say VSTest to redirect standard output

[pascalberger]

The VSTest alias can't do this. As I wrote the StartProcess alias is able to do it.

@devlead Are you like to add this feature to Test Runners?

@pascalberger It is hard to me, because I have to do many thing that VSTest runner done in past
