Félix Malfait 6e1e98f4ab fix(server): shard the server-test unit job to stop the intermittent crash (#23009)
## Problem

`server-test` fails intermittently: exit 1 with **no `FAIL` line and no
`Test Suites:/Tests:` summary** — the jest run is aborted mid-way,
before the reporter's `onRunComplete`.

## Root cause

The `test` target runs the entire unit suite (~6,600 tests) in **one
in-band jest process on a single runner VM** (`nx.json` sets
`maxWorkers: 1` for the `ci` configuration). A few minutes in, that
process is killed by an **external `SIGKILL`** — confirmed *not* OOM
(~15 GB free at kill time, no cgroup `oom_kill`) and *not* an in-process
crash (a Node diagnostic report armed with `--report-on-fatalerror` +
`--report-uncaught-exception` writes nothing). The whole-run kill is why
it fails intermittently with no summary. `maxWorkers=2` on one VM still
dies, so the threshold is **per-VM**, not per-process.

## Fix

Shard the unit suite across VMs, the same way `server-integration-test`
already does:

- A `twenty-server` `test:ci` target runs jest directly (so `--shard`
forwards) with `dependsOn: ["^build"]` so the workspace deps are built.
- `server-test` becomes a 4-way matrix; each shard runs a quarter of the
suite, well under the kill threshold.
- `ci-server-status-check` already aggregates `server-test`, so required
checks are unchanged.

Also provides two mocks a completed run needs but the SIGKILL had been
masking in `ApplicationRegistrationService.upsertFromCatalog` unit
tests: the `MetricsService` provider and
`applicationRegistrationRepository.createQueryBuilder`.

Installation

Cloud

The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.

Build an app

Scaffold a new app with the Twenty CLI:

npx create-twenty-app my-app

Define objects, fields, and views as code:

import { defineObject, FieldType } from 'twenty-sdk/define';

export default defineObject({
  nameSingular: 'deal',
  namePlural: 'deals',
  labelSingular: 'Deal',
  labelPlural: 'Deals',
  fields: [
    { name: 'name', label: 'Name', type: FieldType.TEXT },
    { name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
    { name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
  ],
});

Then ship it to your workspace:

npx twenty app:publish --private

See the app development guide for objects, views, agents, and logic functions.

Self-hosting

Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
