# Test Tasks
# Runs tests across all sub-packages: pathfinder → bindings → core (dependency order)
# Each sub-package has its own pixi.toml; the -e environment propagates via PIXI_ENVIRONMENT_NAME
# Each sub-package has its own pixi.toml; the active environment is forwarded
# explicitly via -e "$PIXI_ENVIRONMENT_NAME" in each inner pixi run.

# Usage: pixi run test | pixi run -e cu12 test | pixi run -e cu13 test
