# Testing
## Automated suite
```sh
cargo test
```
The suite is deterministic and headless: no network, no PTY, no sleeps, no
shared global database. Each test owns its state.
| File | Covers |
| --- | --- |
| `tests/client_core.rs` | Client command/game flows via a headless screen applying logical effects. |
| `tests/client_ui.rs` | Help, history, completion, bet parsing, display width, cursor math. |
| `tests/blackjack.rs` | Card totals, naturals, hit/stand/double, dealer bust, S17, state parsing. |
| `tests/crash.rs` | Multiplier curve, payout floor, crash-point distribution, house edge, cap. |
| `tests/protocol.rs` | Newline buffering and timeout/error classification. |
| `tests/roulette.rs` | Wheel, every bet type and payout, zero handling, cursor lattice, result parser. |
| `tests/server_core.rs` | Handler, bcrypt migration, SQL injection, transaction rollback, `plays` audit, sessions. |
| `tests/server_setup.rs` | `--init` identity generation, PKCS#12 loadability, overwrite refusal. |
| `tests/slots.rs` | Server slots payout rules and overflow handling. |
| `tests/storage.rs` | Client/server SQLite storage helpers. |
| `tests/tofu.rs` | SPKI fingerprint and TOFU decisions. |
`tests/tofu.rs` and `tests/server_setup.rs` shell out to `openssl`, so run them
on a machine where the `openssl` CLI is available.
## Development resets
The server creates `server.db` in its working directory; the client creates
`client.db` for host trust and stored credentials. While the software is in
testing, delete both after a schema or trust change:
```sh
rm -f server.db client.db
```
The audit schema is not auto-migrated from the pre-2.0 slots-only `plays`
table. Starting against an old database will fail until it is removed.
## Manual TUI checklist
There is no CI. Run this on Linux and on a Windows VM before a release.
Use an 80-column terminal because several output lines are width-sensitive.
1. Run `cargo run --bin server -- --init` once, then start the server with a
valid `identity.p12` and start the client.
2. First contact prints three lines and the 64-character fingerprint does not
wrap at 80 columns. `Connected to ...` shows a one-decimal ping.
3. `register` / `login`: backspace removes one `*` per key, Esc cancels the
prompt, Ctrl+C exits and restores the terminal.
4. `help` fits 80 columns. Tab completion wraps within 76 columns and the
cursor stays visible.
5. `play slots 50` shows a 5x3 grid, the `Pays bet x symbol x shape` lines, and
the fetched balance.
6. Space shows `Spinning...`, then the 3 rows, win text, winning-line list, and
new balance inside the same 10-line board. Winning symbols appear as
yellow/bold `{ X }` cells; the `Winning lines:` list names the payline
(e.g. `4 (V)`). The controls line is never overwritten. Slots rules and RTP:
`docs/SLOTS.md`.
7. `+` / `=` / `-` after a spin changes only the bet; no stale grid or result
lines appear.
8. `q` clears the board. Ctrl+C in a game clears the board and exits.
9. `info`, `ping`, `send hello`, and `hosts` print readable output; the host
fingerprint fits 80 columns.
10. Connect to the same server through two addresses (for example `127.0.0.1`
and the machine's LAN IP). `hosts` must list both addresses on one line
under a single fingerprint, because the certificate key is the same.
11. Windows: repeat 2-10 and confirm keys are not duplicated or printed twice.
## Manual roulette checklist
1. `play roulette` draws the full felt: 0, the 3x12 numbers, dozens, columns,
and the six outside cells, with the cursor on number 1.
2. Arrows move the cursor. On the numbers the highlighted cells show the bet:
one number (straight), two (split), four (corner). Down leaves the felt into
the dozens, then columns, then outside; Up walks back.
3. ENTER places the chip where the cursor is; `C` clears; `+`/`=`/`-` change the
chip size. The bets line lists every chip and the total.
4. Space scrolls the wheel under a fixed ball marker and ends on the winning
number.
5. Check the payouts:
- a straight pays 36x, a split 18x, a corner 9x;
- a dozen or column pays 3x;
- an outside bet pays 2x;
- `0` loses every outside bet, both dozens and every column, and pays a
straight 0.
6. The result line names the number, color and parity, the total returned and
the profit. The next spin reuses the placed chips.
## Manual terminal size check
1. Start the client in a terminal smaller than 80x24: it must print
`zagan.bet needs a terminal of at least 80x24 cells` and exit without
switching to the alternate screen or raw mode.
2. At 80x24 every game board (slots 10 lines, roulette 12, blackjack 6, crash 6)
must fit without wrapping.
## Manual blackjack checklist
1. `play blackjack` shows the ready board; Space deals.
2. The dealer's hole card is hidden while it is the player's turn. H/S/D work;
D is only offered on the first two cards and reserves the extra bet.
3. Stand and check the dealer stands on all 17s. Check a dealer bust pays the
player, and a natural blackjack pays 3:2.
4. Q during a hand forfeits the reserved bet (it is **not** refunded); Q after
a hand just leaves. Disconnecting mid-hand also forfeits it.
5. Check the audit row: `game_type = blackjack`, the total bet (including a
double), winnings, and the final cards/result in `details`. A forfeit has
`result = forfeit`, `winnings = 0`.
## Manual crash checklist
1. `play crash` shows the ready board with a 1.00x multiplier; Space starts and
reserves the bet.
2. The multiplier rises smoothly with no network traffic. Cash out with C and
confirm the board shows the cashout multiplier, the payout and the new
balance.
3. On another round, press nothing. The board must switch to `CRASHED at Xx`
by itself when the crash point is reached, and the bet must be lost.
4. Press C just as a round crashes. Either it pays or the crashed result wins;
a late cashout must never show an error over a finished round.
5. Q during a live round forfeits the bet; Q when idle just leaves.
6. Check the audit rows: one per round, `game_type = crash`, the reserved bet,
the payout, and `crash_point`/`multiplier`/`result` in `details`.
7. Confirm the crash point is absent from the `CRASH_START` line (it must only
appear once the round is over).
## Manual restart check
1. Start a blackjack hand (or a crash round) and confirm `pending_plays` has one
row while the round is live.
2. `kill -9` the server, then start it again on the same database. The log must
say `Settled 1 orphaned reservation(s) as abandoned after a restart`.
3. Confirm the balance did not change, `pending_plays` is empty, and `plays` has
one row with `winnings = 0`, `details.result = "abandoned"` and
`details.reason = "server_restart"`.
## Manual identity / credential checklist
1. Connect through one address, `register` and `login`. `hosts` shows the
fingerprint.
2. `disconnect`, then `connect` through another address that reaches the same
server (for example `10.0.0.100` when you first used `127.0.0.1`). The client
must print `Authenticated as <user>` without asking for a password.
3. `hosts` must list both addresses on one line under one fingerprint.
4. `forget-host <first address>` must say the credentials were kept and name
the remaining address. Connecting through the remaining address still
authenticates automatically.
5. `forget-host <last address>` must say trust and credentials were cleared.
The next connect is a first contact and does not authenticate.
## Manual server checks
- Register, log out, log in again (bcrypt path).
- Log in with a pre-0.3 user row (legacy SHA-256) and confirm it still works;
the row is upgraded to bcrypt.
- Spin several times and confirm `plays` grows by one row per spin while
`users.balance` changes by `winnings - bet`.
