# Scrabble Game — Testing
|
|
|
|
How the project is tested and the gate every stage must pass. Read before adding
|
|
tests or touching CI.
|
|
|
|
## Layers
|
|
|
|
- **Go unit tests** — table-driven where it helps; `testing` + standard library.
|
|
Every functional change ships with regression coverage. Run:
|
|
`go test -count=1 ./backend/...` (the module list grows with the workspace).
|
|
- **Integration** *(Stage 1+)* — Postgres-backed tests behind the `integration`
|
|
build tag spin a throwaway `postgres:17-alpine` via `testcontainers-go`. They
|
|
live in `backend/internal/inttest` and run with
|
|
`go test -tags=integration -count=1 -p=1 ./backend/...` (needs Docker), guarded
|
|
by a separate CI workflow (`integration.yaml`; Ryuk disabled, serial). Slow.
|
|
- **UI** *(introduced with the UI in Stage 7)* — Vitest (unit) + Playwright
|
|
(e2e), mirroring the chosen plain-Svelte + Vite toolchain.
|
|
- **Engine** *(Stage 2+)* — correctness of scoring and move generation is owned
|
|
by `scrabble-solver`'s own GCG-backed tests. `backend/internal/engine` adds, on
|
|
top of the embedded solver: per-variant smoke tests (load all three committed
|
|
DAWGs and validate a known word, including Эрудит), bag draw/return determinism
|
|
and exchange accounting, the `Game` end-conditions (empty bag with an empty
|
|
rack, and six scoreless turns) with end-game rack scoring, and
|
|
**dictionary-independent history replay** (`ReplayBoard` reproduces a full
|
|
greedy game's final board from decoded records alone), and the **resignation
|
|
win/loss rule** (the resigner keeps their score yet loses). The engine tests
|
|
read the DAWGs from `BACKEND_DICT_DIR` (or the sibling `scrabble-solver`
|
|
checkout) and fail loudly when it is absent.
|
|
- **Game domain** *(Stage 3+)* — `backend/internal/game` adds pure unit tests
|
|
(the GCG writer, the away-window / effective-deadline boundaries, the hint
|
|
budget, the live-game cache and per-game lock, payload round-trips) plus
|
|
Postgres-backed integration tests in `inttest` (full lifecycle to a natural
|
|
end, **journal-replay equivalence**, the turn-timeout sweep with away-window
|
|
grace, resign win/loss and statistics, the hint allowance-then-wallet policy,
|
|
word-check and complaint capture, and per-game-lock serialisation). Stage 4 adds
|
|
the engine's **multi-player drop-out** cases (continue after one resign,
|
|
last-survivor win, the tile-disposition bag effect) and a domain integration test
|
|
for a 3-player **timeout that continues**. The engine also gains a `Candidates`
|
|
ranked/decoded test (Stage 5).
|
|
- **Social & lobby** *(Stage 4+)* — `backend/internal/social` unit-tests the chat
|
|
**content filter** (links/emails/phones plus obfuscated forms) and
|
|
`backend/internal/lobby` unit-tests the in-memory **matchmaker** (FIFO pairing,
|
|
cancel, per-variant pools, plus the Stage 5 **robot substitution** reaper and
|
|
`Poll` delivery) with fake game-creator and robot-provider seams. Postgres-backed
|
|
`inttest` covers the friend request/accept lifecycle with the block/toggle guards,
|
|
the per-user block (and its severing of friendships), chat post/list with the IP,
|
|
content and block-visibility rules, the nudge turn/rate-limit rules, the
|
|
invitation flow (all-accept starts the game, decline cancels, lazy expiry,
|
|
inviter-only cancel), and the email confirm-code flow (request/confirm, taken
|
|
email, expiry and attempt-cap) with a fixture mailer.
|
|
- **Robot** *(Stage 5+)* — `backend/internal/robot` unit-tests the pure strategy:
|
|
the ≈ 40% play-to-win split over many seeds, the right-skewed move-delay
|
|
(bounds, ~10-min median, determinism), the margin selection (win/lose, in-band
|
|
and out-of-band fallbacks, no-play exchange/pass), the sleep window with drift
|
|
and the midnight wrap, and mix restart-stability. Postgres-backed `inttest`
|
|
drives a robot through a full auto-match to a natural end (asserting a robot
|
|
statistics row), the matchmaker substitution end-to-end (enqueue → reap →
|
|
`[human, robot]`, discoverable via `Poll`), and a proactive 12-hour nudge.
|
|
|
|
## Principles
|
|
|
|
- A green run must not depend on cached state: use `-count=1` in CI.
|
|
- Tests that need infrastructure fail loudly (`t.Fatal`) when it is unavailable
|
|
rather than silently skipping coverage.
|
|
- No network or real platform calls in unit tests; validate platform
|
|
credentials behind an interface seam and test with fixtures.
|
|
|
|
## Per-stage CI gate
|
|
|
|
Every completed stage is exercised on `gitea.iliadenisov.ru` before it is marked
|
|
done in [`../PLAN.md`](../PLAN.md):
|
|
|
|
1. Commit the stage on its `feature/*` branch.
|
|
2. Push to `origin`.
|
|
3. Watch the run to completion — never hand-roll a poll loop:
|
|
`python3 ~/.claude/bin/gitea-ci-watch.py` (launch in the background).
|
|
4. Only after every workflow that fired is green may the stage be marked done.
