 ## Compile and Test Environment

 If the Antigravity/Gemini console/server is not running in the OpenBMC unittest
 container, all compile and testing tasks should be redirected to the container.
 **Always use the `openbmc/ubuntu-unit-test` Docker container for all build and
 test commands.** Otherwise, directly start the task on the bare server, given it
 has been in the container.

 Always compile and run tests in the Docker container.

 Use `.vscode/settings.json` and `.devcontainer/devcontainer.json` to setup the
 docker environment.

 ## Meson Configuration

 To configure Meson inside the OpenBMC unit test container, run the following
 command from the workspace root:

 ```bash
 docker run --rm -v "${PWD}:/ws" -w /ws openbmc/ubuntu-unit-test:2025-W36-725b9a7cb31b8fdf meson setup build_docker
 ```

 ## Object Mapper Setup

 To run the real Object Mapper (`mapperx`) inside the OpenBMC unit test
 container, use the following command in a separate terminal:

 ```bash
 docker run --rm -v "${PWD}:/ws" -w /ws openbmc/ubuntu-unit-test:2025-W36-725b9a7cb31b8fdf bash -c "LD_LIBRARY_PATH=/usr/local/lib/x86_64-linux-gnu/:/usr/local/lib/ /usr/local/libexec/phosphor-objmgr/mapperx --service-namespaces='xyz.openbmc_project' --interface-namespaces='xyz.openbmc_project'"
 ```
