What Mastra Smoke Test does

Mastra Smoke Test is a specialized tool designed for developers working with Mastra projects, facilitating both local and cloud-based smoke testing. This skill enables users to verify the functionality of various components such as the Studio UI, agents, tools, workflows, and memory management. With a structured approach to testing, it ensures that all critical aspects of a project are functioning as expected before deployment.

The smoke testing process is guided by a series of reference files that outline the necessary steps for each test. Users begin by identifying the state of the alpha versioning pull request, which determines the subsequent actions. Depending on whether the pull request is open or merged, users are directed to specific reference files to follow for their smoke testing workflow. This systematic approach minimizes the risk of overlooking important tests and helps maintain project integrity.

In addition to alpha testing, Mastra Smoke Test supports stable release workflows, allowing users to recover from partial publish failures and perform targeted feature checks. The tool emphasizes the importance of thorough testing, urging users to complete all tests unless they encounter a genuine blocker. This ensures that the deployment process is as smooth and reliable as possible.

Overall, Mastra Smoke Test is an essential tool for any developer working with Mastra, providing a clear and organized framework for ensuring the quality and reliability of their projects before they go live.

When to use it

Use Mastra Smoke Test when preparing to deploy a Mastra project to ensure all features and components are operational.

When not to use it

This tool is not suitable for testing projects that do not utilize the Mastra framework or for scenarios requiring extensive functional testing beyond smoke tests.

What you can build with it

Deploying to Staging

Before deploying a Mastra project to staging, run the smoke tests to ensure all components are functional.

Local Development Verification

Use the smoke tests during local development to verify that your changes do not break existing functionality.

Preparing for Production Release

Run comprehensive smoke tests before a production release to catch any critical issues that could affect users.

Mastra Smoke Test

Comprehensive smoke testing for Mastra projects.

Release smoke workflows

Use progressive disclosure: stay in this file until the workflow branches, then read only the reference for the branch you are on. references/release-smoke.md is a short index if you need the full map.

Alpha release branch point

Before alpha smoke testing, identify the alpha versioning PR state. Prefer the standard Changesets release branch:

gh pr view changeset-release/main \
  --json number,title,state,url,headRefName,baseRefName,isDraft,mergeable,reviewDecision,updatedAt,mergedAt,mergeCommit

Expected shape:

title: chore: version packages (alpha)
head: changeset-release/main
base: main

If that branch lookup fails, search open and recently merged PRs:

gh pr list --state open --search 'version packages alpha in:title' --limit 20
gh pr list --state merged --search 'version packages alpha in:title' --limit 20

Then branch:

  • If the versioning PR is open, read references/alpha-versioning-pr.md.
  • If the versioning PR is merged, read references/alpha-publish.md.
  • If no versioning PR exists, report that and wait for the scheduled alpha versioning flow or user direction.

Do not create the alpha smoke-test project until the automatic alpha publish workflow has completed and the intended packages are installable.

Stable release branch point

If the user is running the stable/full release workflow, read references/stable-release-smoke.md. If that workflow fails after some packages publish, switch to references/stable-partial-publish-recovery.md.

Scope and targeted checks

After the release package is published and before running smoke tests, read references/release-scope-discovery.md to identify changed features. Use the default generated project for the baseline checklist, then add targeted checks for changed features the generated project does not exercise.

When scope discovery identifies a branch:

  • For general changed-feature coverage, read references/targeted-feature-smoke.md.
  • For storage/provider schema or migration changes, read references/storage-provider-migration-smoke.md.

⚠️ Mandatory Test Checklist

Use task_write to track progress. Run ALL tests unless --test specifies otherwise.

Do not skip tests unless you hit an actual blocker. "Seemed complex" or "wasn't sure" are not valid reasons. Attempt everything - only stop a test when you literally cannot proceed. Report what you tried and what blocked you.

#TestReferenceWhen Required

3Toolsreferences/tests/tools.md--test tools or full

10Experimentsreferences/tests/experiments.md--test experiments or local full
11Studio Deployreferences/tests/studio.md--test studio (cloud only)
12Server Deployreferences/tests/server.md--test server (cloud only)

Full staging and production runs skip Experiments as not applicable; the companion worker is a local build artifact. A targeted --test experiments run therefore requires --env local.

Execution Flow

  1. Read the reference file for each test you're about to run
  2. Execute the steps in that reference file
  3. Mark the test complete before moving to the next

Partial Testing (--test)

If --test is provided:

  1. Always run Setup (step 1)
  2. Run only the specified test(s)
  3. Skip other tests

Example: --test agents,traces → Run steps 1, 2, and 5 only.

Local Studio Browser Smoke

For local release smoke tests, do both API/curl checks and a Studio browser pass unless --skip-browser is explicitly requested or browser access is genuinely blocked. API checks prove runtime endpoints work; browser checks prove the Playground/Studio UI can load, submit forms, and display results.

Before opening the browser:

  1. Confirm the dev server is alive on the expected port:

    curl -s -o /dev/null -w '%{http_code}\n' http://localhost:4111
    lsof -i :4111 || true
    
  2. If the process died, restart it from the generated project and wait for readiness:

    cd "$SMOKE_DIR/smoke-project"
    pnpm run dev > "$SMOKE_DIR/logs/dev-server-browser.log" 2>&1 &
    
    for i in {1..60}; do
      code=$(curl -s -o /dev/null -w '%{http_code}' http://localhost:4111 || true)
      [ "$code" = 200 ] && break
      sleep 1
    done
    
  3. Use browser tools to navigate to http://localhost:4111. If networkidle times out but domcontentloaded succeeds and the UI is usable, continue and note the timeout.

Recommended browser task list:

1. Verify Studio shell loads
2. Smoke test agent chat UI
3. Smoke test tools UI
4. Smoke test workflows UI
5. Smoke test observability, scorers, and MCP pages
6. Report browser smoke results

Run these page checks:

AreaRouteWhat to verify
Studio shell/ or /agentsSidebar/nav visible, Mastra version visible, no crash/error overlay
Agents/agents → agent chatAgent list shows expected agent, chat input is visible, sending What's the weather in Tokyo? returns a coherent response, tool call badge/result appears when expected
Tools/tools → tool detailTool list shows get-weather, input form renders, submitting a city such as Paris displays JSON result with weather fields
Workflows/workflows → workflow detailWorkflow list shows weather-workflow, graph/details render, running with a city such as Berlin completes as success, steps show timings/output controls
Traces/observabilityRecent agent/workflow traces appear, including runs triggered during the browser pass
Scorers/scorersRegistered scorers appear with names/descriptions, e.g. Tool Call Accuracy, Completeness, Translation Quality
MCP/mcpsPage loads. Empty state is a pass for default templates: No MCP Servers yet

If a browser interaction does not expose enough text in the accessibility snapshot, inspect document.body.innerText or take a screenshot, then record the visible evidence. Do not rely only on API output for browser smoke.

Append browser results to $SMOKE_DIR/smoke-report.md with a separate section, for example:

## Studio Browser Smoke Results

| Area         | Result | Evidence                                                          |
| ------------ | ------ | ----------------------------------------------------------------- |
| Studio shell | PASS   | Browser loaded localhost:4111; sidebar/nav visible; version shown |
| Agents UI    | PASS   | Weather Agent chat returned Tokyo weather and displayed tool call |
| Tools UI     | PASS   | get-weather form returned Paris weather JSON                      |
| Workflows UI | PASS   | weather-workflow Berlin run completed as success                  |
| Traces UI    | PASS   | Recent agent/workflow traces listed                               |
| Scorers UI   | PASS   | Expected scorers listed                                           |
| MCP UI       | PASS   | Expected empty MCP state shown                                    |

Call out separately whether browser smoke was local Studio only or cloud Studio/deployed server.
