# mflux testing

This repo uses pytest with image-producing tests. Always preserve outputs for inspection and **never** update reference images unless explicitly asked.

## When to Use

- You need to run tests (fast/slow/full) or debug failing tests.
- There are image/golden mismatches and you need to report paths/output for review.

## Instructions

- Prefer the Makefile test targets:
  - `make test-fast` (fast tests, no image generation)
  - `make test-slow` (slow tests, image generation)
  - `make test` (full suite)
- Always keep `MFLUX_PRESERVE_TEST_OUTPUT=1` on test runs (already built into the Makefile test targets).
- If a change affects defaults, config resolution, metadata fields, or CLI behavior, add or update tests that cover the changed behavior directly instead of relying only on manual verification.
- If tests fail:
  - Summarize the failing test names and the key assertion output.
  - Point to any generated images/artifacts on disk for manual review.
- Do **not** regenerate/replace reference (“golden”) images unless the user explicitly requests it.

## Manual validation (config resolution + local model paths)

Use when a change touches model config resolution, `mflux-save`, or the model’s generate CLI, or when a PR fixes local model-path handling for the model under investigation. Refer to the `mflux-cli` skill to find the correct generate command for the model you are testing.

- Run a local-path quantize/save:
  - Use the `mflux-cli` skill to look up the correct command and flags.
  - Verify CLI usage with the command’s `--help` before running it.
  - Save to a known location (e.g., Desktop) to make follow-up steps explicit.
- Run generation from the saved model using the correct model-specific generate CLI:
  - Use the `mflux-cli` skill to find the generate command and required flags.
  - Verify CLI usage with the command’s `--help` before running it.
- If the model has multiple size variants, repeat the above for each variant to confirm the correct overrides are applied.
- Do not commit output artifacts; delete or leave them untracked.
