# Checking the code coverage Run every instrumented test suite in the workspace, picking the fastest compiled device backend for the host, then make sure everything is within required limits. Makefile is the source of truth for the gated values, and the code coverage setup. ## Step 1: detect the device Run this once at the start and echo the chosen device: ```bash if [[ "$OSTYPE" == "darwin"* ]]; then DEVICE=metal elif command -v nvidia-smi >/dev/null 2>&1 && nvidia-smi >/dev/null 2>&1; then DEVICE=cuda else DEVICE=cpu fi echo "Device: $DEVICE" ``` `$DEVICE` selects the backend feature for every suite in Step 2, including `test.unit`. Passing the same device through every target keeps the cmake hash stable, so llama.cpp is compiled once and reused across all suites. ## Step 2: run the suites Translate `$DEVICE` into the value the Makefile expects. `TEST_DEVICE` holds **only** the backend name (`cuda` / `metal` / `vulkan` / `rocm`), or empty for CPU since there is no `cpu` feature: ```bash [ "$DEVICE" = "cpu" ] && FEAT= || FEAT="$DEVICE" ``` Then run exactly: ```bash make coverage TEST_DEVICE="$FEAT" ``` ## Step 4: report After all suites finish, sum up the results in an actionable report. Make sure all code coverage gates are met.
