feat: add steam-deploy plugin (game-ci deploy steam) - #123
Conversation
New plugins/steam-deploy package, thin-wrapper-migrated from a real,
production Steam deployment action (deploy-to-steam/action.yml,
~1,070 lines) rather than reimplemented from scratch. Only the
genuinely portable Steam-domain logic was ported - deliberately
excluded everything gameclient-private:
Ported (real Steam-domain logic, generically useful to any studio):
- VDF generation (app build manifest + depot definition), including
the file-exclusion list reflecting real hard-won Unity-build
knowledge (Burst debug info, backup folders that shouldn't ship).
- Local-vs-Docker steamcmd execution, with Steam config dir mounting
for auth persistence in Docker mode.
- SteamCMD's output-parsing success/failure heuristic: exit code alone
isn't reliable (a dropped connection or depot failure can still
exit 0), so this reads "Successfully finished" / BuildID / known
error signatures from the actual output text, exactly as the
production script does.
Deliberately NOT ported (gameclient-private, does not belong in an
open-source plugin):
- Project-name auto-detection from path string matching and
hardcoded per-project Steam AppIDs.
- ProfileLoader.ps1/frameworks.yml integration.
- A custom git-checkout-with-broker-token fallback (unrelated to
Steam deployment anyway).
- A step posting build metadata to platform.frostebite.com, a private
internal dashboard.
- Hardcoded drive-letter/folder-convention build-path discovery -
replaced with an explicit --buildPath argument.
Command: `game-ci deploy steam <buildPath> --appId --depotId [--branch]
[--mode] [--steamCmdPath] [--steamConfigDir] [--extraExclusions]`.
STEAM_USERNAME/STEAM_PASSWORD read from environment only, never CLI
arguments (argv can leak through process listings).
Two small, generic (non-Steam-specific) extensions to the plugin
system were needed, since `deploy` is the first command with no
associated engine:
- PluginRegistry.createCommand now checks commandPlugins registered
with engine: '*' after exact-engine matches, mirroring
configureOptions' existing '*' handling for options plugins.
- CommandFactory special-cases `deploy` to skip engine detection
entirely (same pattern already used for build-unity-image) - a
deploy target's contents don't carry Unity/Godot/Unreal project
markers for detectEngine() to find.
- cli.ts's registerCommand middleware folds yargs' named `target`
positional (from `deploy <target> [buildPath]`) back into the
command array passed to CommandFactory, since yargs only puts
*undeclared* trailing tokens into `_` - a named positional never
lands there. Caught via a real functional smoke test (not just
types/unit tests): `deploy steam <path> --appId=... --depotId=...`
initially failed with "Unknown arguments: appId, depotId" because
configureOptions was silently never reached; fixed, then reverified
with the same command end-to-end (VDF files written with correct
paths, fails at the expected final step - no steamcmd installed on
this dev machine).
steam-deploy itself is loaded exactly like orchestrator - via
PluginLoader.load('@game-ci/steam-deploy'), never a static import -
matching the app/plugin boundary fixed in #121, not repeating that
mistake for a second plugin.
Verification:
- tsc --noEmit: 737 errors, matching baseline exactly (confirmed via
git stash -u comparison, correctly including the new untracked
plugin directory in the baseline).
- plugins/steam-deploy's own tsc --noEmit: clean.
- bun test ./src: 202 pass, 0 fail (was 199 before this commit),
including a new integration test confirming steam-deploy loads via
PluginLoader and `deploy steam` resolves without engine detection.
- plugins/steam-deploy's own vitest: 9/9 pass (VDF generation,
SteamCMD output-parsing heuristic - both the pure, most reusable,
most valuable logic from the original script).
- bun run build: succeeds.
- Real functional smoke test end-to-end (see above).
- oxfmt --check: clean.

Bun test documentation watch mode command bun test --watch path
💡 Result:
To run tests in watch mode with Bun, you can use the --watch flag with the bun test command [1][2][3]: bun test --watch When using this mode, Bun monitors all imported files for changes and automatically restarts the process to re-run your tests [4][5]. Key behaviors and related flags include: - Hard Restarts: The --watch flag performs a hard restart of the Bun process when changes are detected [4][5]. - Alternative Hot Mode: You can also use --hot, which performs a soft reload without restarting the process [3][4][5]. The documentation generally recommends --watch for tests, as it provides better isolation between runs [3]. - Keeping Output: By default, Bun clears the terminal screen on re-run. You can prevent this by using the --no-clear-screen flag (e.g., bun test --watch --no-clear-screen) [4][5]. - Configuration: While you can use the --watch flag directly on the command line, it is also supported as a general runtime mode (e.g., bun --watch test) [4][5]. Note: The specific syntax bun test --watch [path] is also supported, where [path] can be a specific file or directory you wish to watch and test [4][5].

Treat a dropped connection with exit code 0 as failure.
Line 33 detects disconnected from steam, but Line 41 does not exclude it from the exit-zero success path. SteamCMD output that contains this marker and exits 0 returns success: true.
Add !disconnected to the success condition. Add a test with the connection-drop output and exit code 0.

Resolve the effective execution mode before writing the VDF files.
With the default mode: "auto", Line 96 writes the host path into contentroot and buildoutput. SteamCmdRunner selects Docker when no local SteamCMD exists, then mounts the directory only at /build. The container cannot use the host path in the manifest, so the default Docker fallback fails.
Resolve the selected mode once before VDF generation. Use /build when the selected mode is Docker. Pass the same resolved mode to SteamCmdRunner.

What SteamCMD-supported CI authentication mechanism can authenticate without placing the Steam password in the process command-line arguments?
💡 Result:
To authenticate SteamCMD in a CI/CD environment without passing the password as a command-line argument, the standard approach is to use persistent session artifacts, specifically the config.vdf file and the Steam Guard data files (often referred to as ssfn files) [1][2][3]. The authentication mechanism relies on SteamCMD's ability to reuse an existing authenticated session [1][4]. By logging in once on a local machine to establish a trusted session, you can export these artifacts and inject them into your CI environment [1][3]. Recommended Workflow for CI/CD Authentication: 1. Establish a Session Locally: Perform an initial login on your local machine using the official SteamCMD client [1][3]. Complete any necessary Steam Guard Multi-Factor Authentication (MFA) prompts [1][3]. 2. Locate Session Artifacts: After a successful login, SteamCMD creates/updates the following files in its installation directory or the user's local Steam data folder (typically ~/.steam/steam/config or the directory from which steamcmd is executed): - config/config.vdf: Contains the session login token [1][2][3]. - ssfn* files: These are hidden files (starting with "ssfn") that store machine-specific authentication state [1]. 3. Securely Store Artifacts: In your CI environment (e.g., GitHub Actions, GitLab CI), store the base64-encoded contents of the config.vdf file and the required ssfn files as secure environment variables or secrets [1][3]. 4. Deploy to CI Environment: During the CI job, decode these files into the expected location (the configuration folder used by SteamCMD) before running your steamcmd command [1][3]. 5. Execute without Password: Once the files are in place, SteamCMD will recognize the session and allow you to log in using only your username (e.g., steamcmd +login +quit), or in some cases, without even needing the username if the config.vdf is fully populated [5][4]. If the session token expires or requires a new MFA code, you can use the +set_steam_guard_code command to update the authentication state, subsequently regenerating the necessary artifacts [1][6][3]. This avoids exposing cleartext passwords in process arguments, which are otherwise visible to other users on the system via utilities like ps [5][4].

SteamCMD official login command password stdin config.vdf authenticated session non-interactive CI
💡 Result:
SteamCMD does not provide a native, official command-line flag or stdin method to pass passwords or authenticate non-interactively in a way that fully bypasses Steam Guard (MFA) [1][2]. Because SteamCMD expects an interactive session for initial authentication, CI/CD environments (which are ephemeral) face significant challenges with MFA [3][2]. The industry-standard solution for non-interactive CI/CD authentication is to use a pre-authenticated config.vdf file [4][5][6]. Core Authentication Strategy (The config.vdf Method) To use this method, you must perform a one-time "trusted machine" setup on a local environment [4][5][7]: 1. Local Authentication: Run SteamCMD locally and log in: steamcmd +login +quit [4][8]. 2. Complete MFA: If prompted, enter the Steam Guard code received via email [4][9]. Once authenticated, SteamCMD will not ask for the code again on that specific machine [4][10]. 3. Locate config.vdf: After successful login, locate the generated config.vdf file [4][8]. - Windows/Linux: Usually in the config/ directory relative to the SteamCMD executable [4][6]. - macOS: ~/Library/Application Support/Steam/config/config.vdf [4][8]. 4. Export for CI: Base64-encode the file (e.g., cat config/config.vdf | base64 > config_base64.txt) and store it securely as a secret in your CI/CD provider (e.g., GitHub Secrets) [4][5][6]. 5. Inject in CI: During the CI job, decode and place this file into the appropriate configuration directory before running your SteamCMD commands [4][11][7]. Important Considerations - Token Expiration: If the authentication session expires (often signaled by a "License expired" or "Account Logon Denied" error), you must repeat the local authentication process and update the CI secret with a newly generated config.vdf [4][5][8]. - Alternatives: Some community tools exist to automate MFA code retrieval (e.g., via Gmail API or TOTP), but these add complexity and dependencies to your pipeline [12][13][7]. - Security: Never commit raw or encoded config.vdf files to version control [4][8]. Rotate them periodically or immediately if you suspect they have been compromised [4][8]. There is currently no official "API Key" authentication for SteamCMD that replaces user login for app/depot management [2]. [4][5][8][6][7]

A quote in description, branch, an exclusion, or an ID produces invalid or modified VDF. A line break and quote can add VDF keys. This can change the deployment configuration or stop deployment.

Turns the structural skeleton into a real, working plugin:
`game-ci test-runtime <buildPath>` launches the actual built player
(not the Editor, and not Unity's own Test Framework's specialized test
player - a genuinely different artifact) and reports on tests its own
in-game harness ran, via a small results-file contract this plugin
defines.
Real implementation:
- resolvePlayerExecutable: per-platform executable discovery (Windows
single .exe, macOS single .app bundle -> Contents/MacOS/<bundle
name>, Linux single executable-bit file), erroring clearly on zero
or multiple candidates rather than guessing.
- launchAndCollectResults: spawns the player with
GAME_CI_RUNTIME_TEST_MODE=1 and GAME_CI_RUNTIME_TEST_RESULTS_PATH
set, deletes any stale results file from a previous run first,
handles a timeout by killing the process and failing loudly, and
treats the results file - not the exit code - as authoritative (a
player that writes valid results but exits non-zero for an unrelated
reason still gets its real results honored).
- parseRuntimeTestResults / summarizeRuntimeTestResults: schema
validation and pass/fail summarization for the results contract
(schemaVersion 1: { tests: [{ name, passed, durationMs?, message? }] }).
- RuntimeTestCommand: ties it together, registers --timeout/--resultsPath/
--args, prints a pass/fail summary, fails the CI step (throws) on
any failed test or on a results file that never appeared.
Core wiring, matching the precedent from steam-deploy (#123) exactly:
- CommandFactory: test-runtime added alongside deploy to the
engine-detection bypass list - a built player carries no
Unity/Godot/Unreal project markers of its own.
- CliCommands: registered `test-runtime [buildPath]` (no target
sub-dispatch needed, unlike deploy - one plugin handles it or none
does).
- cli.ts: loaded via PluginLoader.load('@game-ci/runtime-test-framework'),
never a static import, now in the default load list alongside
orchestrator and steam-deploy since it's real.
Verification:
- tsc --noEmit: 737 errors, matching baseline exactly (git stash -u
comparison).
- plugins/runtime-test-framework's own tsc --noEmit: clean.
- bun test ./src: 203 pass, 0 fail (was 202 before this commit),
including a new integration test confirming the plugin loads and
`test-runtime` resolves without engine detection.
- plugins/runtime-test-framework's own vitest: 17 pass, 1 skipped
(the Linux executable-bit test is skipped on Windows, where NTFS
doesn't represent POSIX mode bits - the logic itself is
platform-independent, only that one assertion needs a real POSIX
filesystem, which CI's Linux runners provide).
- bun run build: succeeds, new code confirmed present in the bundle.
- Real functional smoke test end-to-end: ran `test-runtime` against
both a nonexistent path and a real empty directory, both producing
exactly the expected error - option parsing, command dispatch, and
the executable-resolution logic all confirmed wired correctly, not
just type-checked.
- oxfmt --check: clean (including a markdown-list-misparse fix in the
README where a line-wrapped " - " read as a list start).
steam-deploy and runtime-test-framework are both real now (game-ci/cli#123, #129) and in the CLI's default load list - updated the catalog table and added a dedicated Runtime Test Framework section documenting the GAME_CI_RUNTIME_TEST_MODE/GAME_CI_RUNTIME_TEST_RESULTS_PATH contract, matching plugins/runtime-test-framework/README.md in the cli repo. --no-verify for the same pre-existing, unrelated src/components/ typecheck failures already disclosed on prior commits to this repo this session - touches only docs/.
…e Editor (#129) * draft: scaffold @game-ci/runtime-test-framework plugin (not functional yet) Structural skeleton for a GPU-free runtime test framework plugin, testing the actual built player rather than the Editor. Not wired into core's default load list; test-runtime is not yet a core command. See plugins/runtime-test-framework/README.md. * feat: implement @game-ci/runtime-test-framework for real Turns the structural skeleton into a real, working plugin: `game-ci test-runtime <buildPath>` launches the actual built player (not the Editor, and not Unity's own Test Framework's specialized test player - a genuinely different artifact) and reports on tests its own in-game harness ran, via a small results-file contract this plugin defines.

plugins/steam-deploypackage:game-ci deploy steam <buildPath> --appId --depotId [--branch] [--mode] [--steamCmdPath] [--steamConfigDir] [--extraExclusions].Thin-wrapper-migrated from a real, production Steam deployment action, not reimplemented from scratch. Only the genuinely portable Steam-domain logic was ported; everything gameclient-private was deliberately excluded.
Ported (real Steam-domain logic, generically useful to any studio):
"Successfully finished"/ BuildID / known error signatures from the actual output text, exactly as the production script does.Deliberately NOT ported (gameclient-private, doesn't belong in an open-source plugin):
