…haskar#56, alihaskar#50) - mkdocs.yml: replace placeholder site_description with the real description from pyproject.toml (alihaskar#56) - interface.py: split the broad except in plot() so DataValidationError is reported with stage="validation" (fixable input) separately from server/runtime failures reported with stage="server" (alihaskar#50) - test_interface.py: assert the validation stage is reported Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Splitting the broad except in plot() left the generic (server/runtime) except branch unexercised once validation errors took their own branch, dropping interface.py coverage below 100%. Add a test that forces a ChartServer startup failure and asserts stage="server". Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The migration to the mirrored tests/<pkg>/** layout never created the data package mirror, so check_test_layout.py failed with a missing tests/pycharting/data/test_ingestion.py. Two problems compounded it: - The flat tests/test_data_ingestion.py and tests/test_data_slicing.py were deleted in the migration without a mirrored replacement. Restore them, merged into tests/pycharting/data/test_ingestion.py with the class layout the checker enforces: TestDataValidationError and TestDataManager (get_chunk slicing folded in), plus module-level functions for validate_input behaviour. - .gitignore had an unanchored `data/` rule (for local sample data) that silently ignored tests/pycharting/data/. Anchor it to `/data/`. check_test_layout.py now exits 0 and data/ingestion.py stays at 100%. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Pull request overview
Restores test-layout parity for pycharting.data by reintroducing a mirrored ingestion test suite under tests/pycharting/data/ and fixing a .gitignore rule that previously prevented that directory from being committed.
Changes:
- Add
tests/pycharting/data/test_ingestion.pyto mirror and coversrc/pycharting/data/ingestion.py(validation +DataManager.get_chunk). - Add
tests/pycharting/data/__init__.pyto complete the mirrored test package structure. - Anchor the
.gitignoredata/rule to/data/so it no longer matchestests/pycharting/data/.

…alihaskar#45, alihaskar#47, alihaskar#49) alihaskar#45 — Test the pragma-excluded websocket/auto-shutdown paths Removed the 5 `# pragma: no cover` markers on the concurrency-critical paths (websocket heartbeat, _monitor_connection stale/disconnect branches, _run_server exception handler, and plot()'s blocking loop) and covered them with tests that drive the handlers directly — no real sockets or timing races. Coverage 100%. alihaskar#47 — Eliminate test-suite flakiness (xdist worker crash, sleep-based readiness) Added tests/pycharting/conftest.py with: - a `wait_until` polling helper replacing fixed `time.sleep` readiness waits, and - a `FakeUvicornServer` / `fake_uvicorn` fixture so behaviour tests exercise the full ChartServer lifecycle without binding real ports. Only the two genuine integration tests still start a real server (now waited on via health polling). Suite went from ~88s to ~9s and passes 10/10 consecutive runs under `-n auto` with no worker crashes. alihaskar#49 — Type the session registry and route responses - `_data_managers` is now `dict[str, DataManager]`. - Route responses use concrete Pydantic models (InitDataResponse, SessionInfo, SessionListResponse, DeleteSessionResponse, StatusResponse). - `plot()` returns a `PlotResult` TypedDict and `get_server_status()` a `ServerStatus` TypedDict instead of `dict[str, Any]`. This surfaced (and fixed) an unchecked-None in `_repr_html_`. `ty` stays clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Fixes the
check_test_layout.pyparity failure for thedatapackage.Root cause
The migration to the mirrored
tests/<pkg>/**layout created mirrors forapiandcorebut never created thedatamirror — the flattests/test_data_ingestion.pyandtests/test_data_slicing.pywere deleted without replacement, sodata/ingestion.pyhad no test file at all.Two problems compounded it:
Missing mirror. Restored both deleted suites, merged into a single
tests/pycharting/data/test_ingestion.py. Organized to satisfy the checker's class-parity rule (eachTest<Class>must map to a source class):TestDataValidationError— every case that raisesDataValidationErrorTestDataManager— construction, properties, repr, andget_chunkslicing (folded in, sinceget_chunkis aDataManagermethod)validate_inputbehaviour (it's a free function, so unconstrained).gitignoreswallowed the dir. An unanchoreddata/rule (meant for local sample data) matchedtests/pycharting/data/— which is why the mirror could never be committed. Anchored it to/data/.Verification
