Apple Container

Run Tests in Linux Container (Apple container CLI)

Run RustPython tests inside a Linux container using Apple's container CLI. NEVER use Docker, Podman, or any other container runtime. Only use the container command.

Arguments

• Test command to run (examples: test_io, test_codecs -v, test_io -v -m "test_errors")

Prerequisites

• The container CLI is installed via brew install container.
• The dev image rustpython-dev is already built.

Workflow

1. Check whether the test container is already running:

   container list 2>/dev/null | grep rustpython-test
   

2. Start the container if it is not running:

   container run -d --name rustpython-test -m 8G -c 4 \
       --mount type=bind,source="$(pwd)",target=/workspace \
       -w /workspace rustpython-dev sleep infinity
   

3. Run the requested test command inside the container:

   container exec rustpython-test cargo run --release -- -m test <test-args>
   

4. Report results:

• Show pass/fail summary and expected failures / unexpected successes.
• Highlight new failures compared to macOS results, if available.
• Do not stop or remove the container after testing.

Notes

• The workspace is bind-mounted, so local code changes are immediately available in the container.

• Use container exec rustpython-test sh -c "..." for any command inside the container.

• Rebuild after code changes with:

  container exec rustpython-test sh -c "cargo build --release"
  

• Stop the container when explicitly requested:

  container rm -f rustpython-test
