Jordi Enric 6c6ac567b1 feat(studio): workers list behind the workers flag (FE-4188) (#49193)
## What

The Workers list page at `/project/[ref]/workers`, behind
`useFlag('workers')`. Reads `GET /v2/projects/{ref}/workers`.

- Sidebar and command-menu entries, both hidden when the flag is off
- Name search, state and access filters, pagination
- Read-only

Gating, in order: flag off redirects to the project home; a 404 from the
API means the project is outside the alpha allow-list ("not enabled for
this project"); a 403 means the caller lacks the permission
(`NoPermission`); anything else is an `AlertError`.

`parseWorker` in `data/workers/workers.utils.ts` is the only place the
API shape becomes the view model. It validates with zod, so a drifted
response fails the query instead of half-rendering a row.

## How to test

Only on the **Mockamaster** project in staging — it is the one project
in the alpha allow-list, and standing a worker up anywhere else is
involved right now.

1. Staging dashboard → Mockamaster → **Compute** in the sidebar
2. Expect the `dashboard-test` worker: state `Active`, runtime Deno,
private, US West, 2 GB · 1 vCPU · 1 inst
3. Open any other project's `/workers` URL → "Compute is not enabled for
this project"
4. Turn the `workers` flag off → the sidebar entry disappears and the
URL redirects to the project home

UI Testing Notes

Rules

  • All tests should be run consistently (avoid situations whereby tests fails "sometimes")

  • Group tests in folders based on the feature they are testing. Avoid file/folder based folder names since those can change and we will forget to update the tests.

Examples: /logs /reports /projects /database-settings /auth

Custom Render and Custom Render Hook

customRender and customRenderHook are wrappers around render and renderHook that add some necessary providers like QueryClientProvider, TooltipProvider and NuqsTestingAdapter.

Generally use those instead of the default render and renderHook functions.

import { customRender, customRenderHook } from 'tests/lib/custom-render'

customRender(<MyComponent />)
customRenderHook(() => useMyHook())

Mocking API Requests

To mock API requests, we use the msw library.

Global mocks can be found in tests/lib/msw-global-api-mocks.ts.

To mock an endpoint you can use the addAPIMock function. Make sure to add the mock in the beforeEach hook. It won't work with beforeAll if you have many tests.

beforeEach(() => {
  addAPIMock({
    method: 'get',
    path: '/api/my-endpoint',
    response: {
      data: { foo: 'bar' },
    },
  })
})

API Mocking Tips:

  • Keep mocks in the same folder as the tests that use them
  • Add a test to verify the mock is working

This will make debugging and updating the mocks easier.

test('mock is working', async () => {
  const response = await fetch('/api/my-endpoint')
  expect(response.json()).resolves.toEqual({ data: { foo: 'bar' } })
})

Mocking Nuqs URL Parameters

To render a component that uses Nuqs with some predefined query parameters, you can use customRender with the nuqs prop.


customRender(<MyComponent />, {
  nuqs: {
    searchParams: {
      search: 'hello world',
    },
  },
})

<Popover> vs <Dropdown>

When simulating clicks on these components, do the following:

// for Popovers
import userEvent from '@testing-library/user-event'
await userEvent.click('Hello world')

// for Dropdowns
import clickDropdown from 'tests/helpers'
clickDropdown('Hello world')
