Objective

A repository at /home/interview/repo has a Node.js application with a test suite. The team needs a two-stage pipeline where the first job runs tests and the second job creates a summary report from those results. The repository has upload-artifact and download-artifact actions available locally at .github/actions/.

Task

Complete the workflow at .github/workflows/artifact-handoff.yml that triggers on pull_request events using container images (node:20-slim). Job A (test-job) should check out code, run ./run-tests.sh, and upload test-results.txt as an artifact named test-results. Job B (report-job) should depend on Job A using needs, download the test-results artifact, count passed tests with grep -c "PASS:", save the count to summary.txt as "Total Passed Tests: X", and upload it as a test-summary artifact.

Explanation

Step 1: Test Job Uploads Artifact

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

After running the tests, the test job uploads test-results.txt as an artifact. This file is stored by GitHub Actions and can be downloaded by other jobs in the same workflow.

Step 2: Report Job Downloads Artifact

report-job:
  needs: test-job
  steps:
    - uses: ./.github/actions/download-artifact
      with:
        name: test-results

needs: test-job ensures the report job waits for the test job to finish. Then download-artifact retrieves the test-results artifact that was uploaded in the previous job. The file appears in the working directory as test-results.txt.

Step 3: Create Summary

- name: Create summary report
  run: |
    PASSED_COUNT=$(grep -c "PASS:" test-results.txt || echo "0")
    echo "Total Passed Tests: $PASSED_COUNT" > summary.txt

grep -c "PASS:" counts the number of lines containing "PASS:" in the test results. The -c flag returns the count instead of the matching lines. || echo "0" is a fallback: if grep finds no matches it exits with code 1, so || echo "0" catches that and outputs "0" instead of failing the step. The count is then written to summary.txt.
