CDEvents in Action #7: Instrument Any CI Step in a Few Lines

Webhook integrations (ep#3, ep#4) tell you when a pipeline started and whether it passed. They don't tell you which test suites ran, which failed, or how long each step took. send --run fills that gap.

The Pattern

Prefix any CI command with cdviz-collector send --run <type> [options] --:

# before
npm test

# after — expects npm test to produce JUnit XML output
cdviz-collector send --run testsuiterun_junit \
  --url "$CDVIZ_URL" \
  --header "Authorization: Bearer $CDVIZ_TOKEN" \
  -- npm test

The collector runs your command normally. When it exits, it emits testSuiteRun.started + testSuiteRun.finished CDEvents with parsed test results included. Your exit code is preserved — CI still fails if tests fail.

[!NOTE]
Authentication: --header "Authorization: Bearer $TOKEN" is shown here for clarity. HMAC signature authentication is also supported and may be preferred depending on your server configuration. See the send documentation for options.

Choose the Right --run Type

[!TIP]
More options, custom run types, and output path overrides are available — see the send --run reference.

CI Auto-Detection

Branch, commit SHA, and job name are read automatically — no --metadata flags needed for those:

GitHub Actions Example

Install the binary once, then wrap each step:

- name: Install cdviz-collector
  run: |
    curl --proto '=https' --tlsv1.2 -LsSf https://github.com/cdviz-dev/cdviz-collector/releases/latest/download/cdviz-collector-x86_64-unknown-linux-musl.tar.xz \
      | tar xJ -C /usr/local/bin --strip-components=1 cdviz-collector-x86_64-unknown-linux-musl/cdviz-collector
    chmod +x /usr/local/bin/cdviz-collector


- name: Build
  run: |
    cdviz-collector send --run taskrun \
      --url "${{ secrets.CDVIZ_URL }}" \
      --header "Authorization: Bearer ${{ secrets.CDVIZ_TOKEN }}" \
      -- npm run build

- name: Test # expects JUnit XML output from npm test
  run: |
    cdviz-collector send --run testsuiterun_junit \
      --url "${{ secrets.CDVIZ_URL }}" \
      --header "Authorization: Bearer ${{ secrets.CDVIZ_TOKEN }}" \
      -- npm test

Add CDVIZ_URL and CDVIZ_TOKEN as repository secrets (Settings → Secrets and variables → Actions). See the GitLab CI and Jenkins guides for equivalent setups.

Cross-Reference with an Artifact (Optional)

If you built a Docker image earlier in the pipeline, pass its digest with --metadata to link test results to that exact image:

cdviz-collector send --run testsuiterun_junit \
  --metadata "tested_artifact_id=pkg:oci/my-app@sha256:$IMAGE_SHA" \
  --url "$CDVIZ_URL" \
  --header "Authorization: Bearer $CDVIZ_TOKEN" \
  -- npm test

CDviz records a testedAgainst link between the test run and the artifact — useful for tracing which image version a test failure was against.

What You Get

• Test trend dashboards — pass/fail rates per suite over time
• Step durations — how long build, test, and deploy steps take per commit
• Failure context — which suite failed, on which branch, at which commit
• Artifact traceability — which tests ran against which image (when tested_artifact_id is set)
