e846d45ce6 chore(studio): retry flaky unit tests in CI (#48939)
<!-- ccr-slack-attribution -->
_Requested via [Slack
thread](https://supabase.slack.com/archives/C063LNYJJKS/p1786454906416269?thread_ts=1786454906.416269&cid=C063LNYJJKS)_

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Chore / CI reliability. One-line config change to
`apps/studio/vitest.config.ts`.

## What is the current behavior?

**Before:** the `Studio Unit Tests & Build Check` workflow sometimes
goes red on `master` for no reason anyone can act on. Since 2026-07-29
it failed 3 out of 82 test executions (3.7%), every time at job `test
(1)`, step `Run Tests`. Every one of those three passed on a re-run with
no code change:

- https://github.com/supabase/supabase/actions/runs/31495760766
(`4587d177`, Aug 11)
- https://github.com/supabase/supabase/actions/runs/31409667566
(`b04d1485`, Aug 10)
- https://github.com/supabase/supabase/actions/runs/31203465483
(`777c02c2`, Aug 7)

Each failure also posts a Slack alert to #team-frontend-alerts via
`.github/workflows/studio-master-alert.yml`, so someone gets pinged,
opens the run, clicks re-run, and it goes green.

## What is the new behavior?

**After:** a test that fails in CI gets up to two more attempts before
the job is marked failed. A genuinely broken test still fails all three
attempts and still goes red. Locally nothing changes — the first failure
is the result you see, so you are never waiting on retries while
debugging.

## Additional context

**How:** added `retry: IS_CI ? 2 : 0` to the `test` block of
`apps/studio/vitest.config.ts`, with `const IS_CI = !!process.env.CI`
matching the pattern already used in
`e2e/studio/playwright.config.ts:51` (`retries: IS_CI ? 5 : 0`).

**Known limitation — we do not know which test is flaking.** The GitHub
Actions log downloads for those three runs were not retrievable, and the
API only surfaces `Process completed with exit code 1`. So this treats
the symptom without naming the cause.

The natural follow-up is to upload a JUnit or JSON vitest report as an
artifact with `if: always()`, which would name the flaking test on the
next failure. That is deliberately **not** in this PR — it is a workflow
change and was scoped out.

One more honest caveat: per-test retry only helps if the failure is an
assertion or timeout inside a test. If the real cause is a worker crash
or OOM, retrying will not save the run. That is a live possibility here
— the workflow sets `NODE_OPTIONS: '--max_old_space_size=3072'` with the
in-repo comment "Default is 2 GB, increase to have less frequent OOM
errors", which says someone has already hit memory pressure in this job.

So: worth landing as a cheap reduction in false alarms, but if the 3.7%
does not drop, the report artifact is the next step rather than more
retries.

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
