Objective

A repository at /home/interview/repo has a test suite but no automated testing on pull requests. The repository has the upload-artifact action available locally at .github/actions/upload-artifact.

Task

Complete the workflow at .github/workflows/pr-tests.yml so that it triggers on pull request events, runs the test suite ./run-tests.sh, and uploads the test results from test-results.txt as an artifact named test-results using ./.github/actions/upload-artifact. The artifact upload should run even if tests fail.

File Path

• Workflow: /home/interview/repo/.github/workflows/pr-tests.yml
• Test suite: /home/interview/repo/run-tests.sh

name: pr-tests

on:
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Run tests
        run: ./run-tests.sh

      - name: Upload test results
        if: always()
        uses: ./.github/actions/upload-artifact
        with:
          name: test-results
          path: test-results.txt

Explanation

Step 1: Checkout the Repository

- uses: actions/checkout@v4

Same as any workflow, the runner starts empty. actions/checkout pulls the repo code so we can run the test script and access the local upload-artifact action.

Step 2: Run the Test Suite

- name: Run tests
  run: ./run-tests.sh

This executes the test script, which writes results to test-results.txt. If any test fails, the script exits with a non-zero code, which would normally stop the workflow.

Step 3: Upload Artifacts with if: always()

- name: Upload test results
  if: always()
  uses: ./.github/actions/upload-artifact
  with:
    name: test-results
    path: test-results.txt

if: always() is the key here. Without it, this step would be skipped when the test step fails (since GitHub Actions stops on failure by default). With if: always(), the upload runs regardless of whether previous steps passed or failed. The uses: ./.github/actions/upload-artifact references a local action bundled in the repo. name sets the artifact identifier and path points to the file to upload.
