name: test-runtime-sim

description: Run simulation tests for one runtime ($ARGUMENTS — host_build_graph or tensormap_and_ringbuffer). Use when the user asks to test a single runtime in simulation.

# Run simulation tests for a single runtime specified by $ARGUMENTS

Detection procedures referenced below live in

[`../../lib/onboard-detection.md`](../../lib/onboard-detection.md).

1. Validate that `$ARGUMENTS` is one of: `host_build_graph`,

`tensormap_and_ringbuffer`. If not, list the valid runtimes and stop.

- 2. **Extract CI pins** (§D, sim jobs): `--pto-isa-commit` and

- `--pto-session-timeout`.

+ 2. **Extract CI timeout** (§D, sim jobs): `--pto-session-timeout`.

3. **Detect platform** (sim, §B).

4. Run:

```bash

pytest examples tests/st --platform <platform> --runtime $ARGUMENTS \

- --pto-session-timeout <timeout> --clone-protocol https \

- --pto-isa-commit <commit> -v

+ --pto-session-timeout <timeout> -v

```

xdist parallelism is auto-selected via `--max-parallel auto` (min of nproc

and device pool size on sim); see `docs/testing.md`.

5. Report the results summary (pass/fail counts).

6. If any tests fail, show the relevant error output.
