From f77f0af33a4d65e25153dc817fc2b21bee5bc5f5 Mon Sep 17 00:00:00 2001 From: Netherwarlord Date: Tue, 28 Jul 2026 20:26:56 -0400 Subject: [PATCH] Add comprehensive test suites for answer key validation, API functionality, and code linting - Introduced `test_answer_key.py` to validate the correctness of answer keys against expected responses, ensuring both false and true answers are graded appropriately. - Created `test_answer_values.py` to verify the accuracy of answer keys by recomputing values and comparing them against the provided `answers.json`. - Implemented `test_api.py` to test the HTTP API for suite management, ensuring read-only enforcement and proper handling of custom suites. - Added `test_code_lint.py` to perform static code analysis, ensuring that all linting rules are enforced without false positives on correct answers. - Developed `test_collision.py` to guard against prompt mismatches due to filename collisions across suites. - Created `test_gguf.py` to validate GGUF header parsing and model classification, including handling of malformed input. - Introduced `test_linter.py` to ensure report rendering preserves content integrity and correctly fences code. - Added `test_reporting.py` to verify report naming conventions and the accuracy of per-suite score breakdowns. --- README.md | 13 +++ tests_py/README.md | 52 +++++++++ tests_py/_harness.py | 109 +++++++++++++++++++ tests_py/run_all.py | 71 +++++++++++++ tests_py/test_answer_key.py | 98 +++++++++++++++++ tests_py/test_answer_values.py | 189 +++++++++++++++++++++++++++++++++ tests_py/test_api.py | 120 +++++++++++++++++++++ tests_py/test_code_lint.py | 101 ++++++++++++++++++ tests_py/test_collision.py | 62 +++++++++++ tests_py/test_gguf.py | 95 +++++++++++++++++ tests_py/test_linter.py | 113 ++++++++++++++++++++ tests_py/test_reporting.py | 99 +++++++++++++++++ 12 files changed, 1122 insertions(+) create mode 100644 tests_py/README.md create mode 100644 tests_py/_harness.py create mode 100644 tests_py/run_all.py create mode 100644 tests_py/test_answer_key.py create mode 100644 tests_py/test_answer_values.py create mode 100644 tests_py/test_api.py create mode 100644 tests_py/test_code_lint.py create mode 100644 tests_py/test_collision.py create mode 100644 tests_py/test_gguf.py create mode 100644 tests_py/test_linter.py create mode 100644 tests_py/test_reporting.py diff --git a/README.md b/README.md index c56a5cf..bd9069a 100644 --- a/README.md +++ b/README.md @@ -300,6 +300,18 @@ Reports are written to `results/automated_report_.md`. --- +## Tests + +```bash +python tests_py/run_all.py # 195 assertions, no dependencies +cd web && npm test # 29 UI assertions +``` + +`tests_py/test_api.py` needs a running server and skips cleanly without one. +Details in [`tests_py/README.md`](tests_py/README.md). + +--- + ## Project structure ``` @@ -320,6 +332,7 @@ server/ FastAPI backend wrapping the engine plugins/ Drop-in plugins — _skeleton.py is the starter template plugin_api.py Stable types plugins import plugin_system.py Plugin discovery and hook dispatch +tests_py/ Python tests — python tests_py/run_all.py web/ React + TypeScript interface (Vite) models/ Drop .gguf or MLX weights here (auto-discovered) .core/suites// Built-in suites, read-only diff --git a/tests_py/README.md b/tests_py/README.md new file mode 100644 index 0000000..9c39c1f --- /dev/null +++ b/tests_py/README.md @@ -0,0 +1,52 @@ +# Python tests + +```bash +python tests_py/run_all.py # everything +python tests_py/run_all.py gguf key # only files matching those words +python tests_py/test_linter.py # one file directly +``` + +Exits non-zero if anything fails, so it works as a CI entry point. + +No third-party dependencies. `test_api.py` needs a running server +(`python app.py`) and the `requests` package the LM Studio provider already +uses; it prints `SKIP` and passes when the server is down, so the rest stay +useful offline. + +| File | Covers | +| --- | --- | +| `test_answer_values.py` | The answer keys themselves, recomputed from scratch | +| `test_answer_key.py` | The correctness grader, both directions | +| `test_api.py` | Suites API, read-only guards, run selection | +| `test_code_lint.py` | Static code rules, and the false positives they must not repeat | +| `test_collision.py` | Qualified question IDs | +| `test_gguf.py` | GGUF header parsing and model classification | +| `test_linter.py` | Report rendering | +| `test_reporting.py` | Report naming and the per-suite breakdown | + +The UI tests live separately, under `web/src/**/*.test.tsx` — run them with +`cd web && npm test`. + +## Why these are scripts rather than `unittest` cases + +They exercise a diagnostic tool, so the output is read as much as the exit +code. `test_code_lint.py` is a table of which rules fire on which input, and +that is worth more when debugging a false positive than a row of dots. +`run_all.py` aggregates exit codes for the times you only want a verdict. + +Each file runs in its own process.
