# Deploy Release Test Use this skill only when manually running the entire Next.js deployment test suite for a pull request. Treat package validation as a hard gate: never dispatch the workflow until the exact commit's redirected tarball responds successfully. ## Scope Do not use this workflow to sanity-check one deployment test or a focused group of tests. Follow [Running Deploy Tests Locally](../../../contributing/core/testing.md#running-deploy-tests-locally) instead: ```bash NEXT_TEST_VERSION=https://vercel-packages.vercel.app/next/commits/<commit-sha>/next pnpm test-deploy <path-to-test> ``` If a request to "run deploy tests" does not explicitly call for the entire suite, prefer the focused local workflow and scope it to the affected tests. ## Inputs - Accept a PR number or determine the PR from the current branch. - Use repository `vercel/next.js` and workflow `.github/workflows/test_e2e_deploy_release.yml`. - Require the PR head branch to exist in `vercel/next.js`. A fork branch cannot run this secret-bearing workflow; use the repository's PR adoption process first when appropriate. ## Workflow 1. Resolve the PR branch and its latest commit from GitHub, not merely from the local checkout: ```bash gh pr view <pr-number> --repo vercel/next.js \ --json number,url,headRefName,headRefOid,isCrossRepository ``` If no PR number was supplied, omit `<pr-number>` to detect the PR from the current branch. Stop if `isCrossRepository` is `true`. Record `headRefName` as the branch and `headRefOid` as the commit SHA. 2. Construct the exact package URL: ```text https://vercel-packages.vercel.app/next/commits/<commit-sha>/next ``` 3. Wait for the package to become downloadable before dispatching anything: ```bash node scripts/wait-for-preview-tarball.mjs --commit-sha <commit-sha> ``` Keep the wait in an ongoing terminal session and poll it so the user still receives progress updates. The helper uses `HEAD`, follows the redirect to Vercel Blob, and only succeeds when the final artifact is available. Do not substitute a check that accepts the initial redirect: that endpoint can redirect even while the blob still returns 404. If the helper times out or reports an authorization or build failure, do not dispatch the workflow. Report the failure and inspect the commit's `build-and-deploy` / `upload-preview-tarballs` checks if useful. 4. Resolve the PR again immediately after validation. Compare the current `headRefName` and `headRefOid` with the recorded values. If either changed, return to step 2 and validate the new commit-specific URL. Never reuse the old package URL for a moved branch. 5. Trigger the workflow from the PR branch and pass only `nextVersion`: ```bash gh workflow run test_e2e_deploy_release.yml \ --repo vercel/next.js \ --ref <pr-branch> \ -f nextVersion=https://vercel-packages.vercel.app/next/commits/<commit-sha>/next ``` Do not pass any other `-f` values. Leaving them unspecified preserves the workflow defaults, including `vercelCliVersion: vercel@latest` and empty optional overrides. 6. Find and verify the newly created run: ```bash gh run list --repo vercel/next.js \ --workflow test_e2e_deploy_release.yml \ --branch <pr-branch> \ --event workflow_dispatch \ --limit 5 \ --json databaseId,url,status,conclusion,headBranch,headSha,displayTitle,createdAt ``` Confirm that the newest matching run has: - `headBranch` equal to the PR branch - `headSha` equal to the validated commit SHA - `displayTitle` containing the exact commit-specific package URL A race can still move the branch between the final check and dispatch. If the run's `headSha` differs, report the mismatch and do not trigger another run until the new SHA's package has been validated. ## Completion Report Report the PR branch, validated SHA and package URL, workflow run URL, and its current status. Do not wait for the full deployment suite unless the user asks you to monitor it. ## Related Skills - `$pr-status-triage` - Inspect failures if the deployment workflow does not pass. - `$create-pr` - Create or update the internal PR branch before deployment testing.
