arc-bench is a benchmark for requirement-to-application generation. It
evaluates whether a generation system can transform multi-modal web application
requirements into a runnable implementation whose behavior is validated by
end-to-end Playwright tests.
The benchmark is organized as a set of web application tasks. Each task pairs a requirement package with an executable test suite, so different generators can be compared against the same inputs and behavioral checks. This repository contains:
arc-bench/webapp/<app>/requirements/: structured requirements for the benchmark web apps;arc-bench/webapp/<app>/tests/: Playwright tests for those apps;arc-bench/webapp/<app>/project/: optional reference implementation for an app;scripts/run-playwright.jsandplaywright.config.ts: the benchmark test runner;Dockerfile: an optional containerized benchmark execution environment.
The benchmark itself is generator-agnostic. Any implementation, whether it is produced by a generator or written as a reference implementation, is responsible for starting successfully, initializing the data required by the requirements, and exposing one entry URL. The benchmark runner is responsible only for running the selected app's tests against that URL.
Requirement counts are the number of atomic requirement nodes in
requirements.yaml. Test counts are the number of Playwright test(...) cases.

The benchmark usage is independent of any particular generation method:
arc-bench/webapp/<app>/requirements/
-> generate a runnable web application with a chosen method
-> the implementation starts, initializes required data, and exposes an entry URL
-> run arc-bench/webapp/<app>/tests/ against that URL
Install the local test runner when running tests directly on the host:
npm install
npm run test:installRun one benchmark application's tests against a running application:
npm run test -- --app bookstack --target-url http://127.0.0.1:3301If the application is already deployed and you only have an entry URL, pass the
URL with --target-url. The runner uses that URL as Playwright's baseURL.
No environment variables are required for this path.
npm run test -- --app bookstack --target-url https://your-app.example.comTo run the same tests inside the Docker benchmark environment, use:
npm run test:docker -- --app bookstack --target-url https://your-app.example.comWhen the application is running on the host machine, a localhost URL must be
reachable from inside Docker. The npm wrapper rewrites localhost,
127.0.0.1, and 0.0.0.0 to host.docker.internal for the container:
npm run test:docker -- --app bookstack --target-url http://127.0.0.1:3301Docker test outputs are exported to:
docker-output/test/<app>/
|-- test-results/
`-- playwright-report/
The Docker image in this repository provides a benchmark execution environment: Node.js, Playwright browsers, the benchmark runner, and benchmark files. For an already-running implementation, the Docker test command only needs the selected app and the entry URL.
Reference implementations can be placed under:
arc-bench/webapp/<app>/project/
The reference app must listen on PORT and expose a health endpoint at
/api/health. It must initialize the database or other seed data required by
the requirements during startup. It does not own or execute the benchmark E2E
tests.
Build or rebuild the benchmark image after changing Docker scripts or the test runner:
npm run docker:buildThe image prepares the benchmark test environment and the Playwright Chromium
browser cache used by the benchmark runner. It does not include reference
implementation source code or reference node_modules.
If a run reports a missing path such as
/ms-playwright/chromium_headless_shell-xxxx/..., rebuild the image. That error
means the image's browser cache does not match the benchmark runner's
@playwright/test version.
Run the 12306 reference implementation in Docker, then execute the benchmark
tests against the URL exposed inside the container:
npm run reference -- --app 12306Equivalent shorthand:
npm run reference:12306This command does not require manually setting PORT, TARGET_URL,
PLAYWRIGHT_BASE_URL, or ARC_TEST_DATE. The wrapper chooses the container
port, starts the reference implementation, and calls the benchmark runner with
the resulting URL.
The reference flow performs the following steps in one fresh container:
mount arc-bench/webapp/12306/project/
mount arc-bench/webapp/12306/tests/
-> copy source to /workspaces/reference/12306/project
-> install dependencies inside the Linux container
-> build the frontend if package.json defines `build`
-> start the reference backend on PORT=3301
-> wait for http://127.0.0.1:3301/api/health
-> run `npm run test -- --app 12306 --target-url http://127.0.0.1:3301`
This section is an application example of the benchmark using ARC (Agentic Requirement Compiler) as the generation method. This repository is not a standalone implementation of the ARC compiler; the compiler and its application templates are provided through Git submodules.
Install the following for the ARC baseline example:
- Docker Desktop on Windows/macOS or Docker Engine on Linux;
- access to an OpenAI-compatible model API.
Clone the benchmark repository and initialize the ARC compiler submodule and its nested submodules:
git submodule sync --recursive
git submodule update --init --remote --recursiveThe environment file belongs to the ARC compiler submodule. Read the configuration instructions in:
agentic-requirement-compiler/README.md
Create the compiler environment file from the template.
Linux/macOS:
cp agentic-requirement-compiler/.env_example \
agentic-requirement-compiler/.envWindows PowerShell:
Copy-Item `
agentic-requirement-compiler\.env_example `
agentic-requirement-compiler\.envEdit agentic-requirement-compiler/.env according to the ARC compiler README.
At minimum, configure the model API credentials and model name. The file is
passed to Docker at runtime and is excluded from the Docker image.
For one application, the complete flow is:
arc-bench/webapp/<app>/
|-- requirements/ input requirements and reference assets
`-- tests/ Playwright tests for the generated app
ARC compiles `arc-bench/webapp/<app>/requirements/`
-> generated backend starts on port 3301
-> /api/health becomes available
-> Playwright tests run from `arc-bench/webapp/<app>/tests/`
-> application, logs, raw results, and HTML report are exported
The recommended ARC baseline command performs all steps in one isolated
container. The examples below use bookstack; replace it with another benchmark
app name as needed.
If you add or modify arc-bench/, apps.config.json, scripts/, or
docker/entrypoint.sh, rebuild the image before running the container again.
The image copies those files at build time.

The container entrypoint performs:
arc compile
-> PORT=3301 npm run start
-> wait for http://127.0.0.1:3301/api/health
-> npm run test -- --app <app-name>
The container exits with:
0when compilation, startup, and tests succeed;- a non-zero status when compilation fails, the health check fails, or tests fail.
The one-container command above is recommended for complete reproduction. The following commands are useful when debugging or running one stage separately.
Linux/macOS:
docker build --progress=plain -t arc-reproduction:latest .Windows PowerShell:
docker build --progress=plain -t arc-reproduction:latest .Parameter meanings:
docker build: builds an image from theDockerfile;--progress=plain: prints complete build logs;-t arc-reproduction:latest: assigns the image name and tag;.: uses the current repository as the Docker build context.
This command runs ARC compilation without starting the generated application or running Playwright.

--cleanParameter meanings:
--entrypoint arc: bypasses the default Docker entrypoint and calls the installed ARC CLI directly;compile: compiles a requirement directory into an application;/opt/arc/arc-bench/webapp/bookstack/requirements: the requirement directory inside the image;-o /export/bookstack/application: the generated application output directory;--type web: selects web application generation;--clean: removes an existing output directory before compilation;--mount ...:/export: persists the container output underdocker-output/bookstack/applicationon the host.
The default entrypoint already starts and tests a newly generated application. To test an existing generated application, mount it into a fresh container, start its backend, wait for the health endpoint, and run Playwright.

Otherwise, use the complete one-container command.
