How to run a github-actions step, even if the previous step fails, while still failing the job

Question

I'm trying to follow an example Github has for testing my build with github actions, and then compressing the test results and uploading them as an artifact. https://help.github.com/en/actions/automating-your-workflow-with-github-actions/persisting-workflow-data-using-artifacts#uploading-build-and-test-artifacts

I'm having trouble with what to do when my tests fail though. This is my action. When my tests pass everything works great, my results are zipped an exported as an artifact, but if my tests fail, it stops the rest of the steps in the job, so my results never get published.

I tried adding the continue-on-error: true https://help.github.com/en/actions/automating-your-workflow-with-github-actions/workflow-syntax-for-github-actions#jobsjob_idstepscontinue-on-error
This makes it continue after it fails and uploads my test results. but then the job is marked as passed, even though my test step failed. Is there some way to have it upload my artifact even if a step fails, while still marking the overall job as failed?

    steps:
    - uses: actions/checkout@v1    
    - name: Test App
      run: ./gradlew test

    - name: Archive Rest Results
      uses: actions/upload-artifact@v1
      with:
        name: test-results
        path: app/build/reports/tests

Answer 1

You can add

if: always()

to your step to have it run even if a previous step fails https://help.github.com/en/actions/automating-your-workflow-with-github-actions/contexts-and-expression-syntax-for-github-actions#job-status-check-functions

Addon: if you have following sitution. 2 steps i.e. build > deploy and in some cases i.e. workflow_dispatch with input parameters you might want to skip build and proceed with deploy. At the same time you might want deploy to be skipped, when build failed.
Logically that would be something like skipped or not failed as deploy conditional.
if: always() will not work, cause it will always trigger deploy, even if build failed.
Solution is pretty simple:
if: ${{ !failure() }}
Mind that you cannot skip brackets when negating in if:, cause it reports syntax error.
