GUI Sandbox

The existing pytest scenario tests/gui/test_daily_workflow_smoke.py drives MainWindow through four unchanged representative programs. QSettings, the tool library, logs, HTML and NC exports use pytest temporary storage. No fixture is rewritten and the user library is never opened or changed.

# Visible simulation demonstration
.\scripts\ps1\start-sandbox.ps1
# Offscreen regression, without GPU rendering claims
.\scripts\ps1\start-sandbox.ps1 -Automated

bash scripts/sh/start-sandbox.sh
bash scripts/sh/start-sandbox.sh --automated

Use -DelayMs 1500 or --delay-ms 1500 to change presentation pauses. The launchers preserve pytest exit status; PowerShell restores its environment and Bash confines overrides to the child process. Visible mode requires a visible Qt platform; automated mode selects offscreen and disables presentation pauses.

Presentation and regression

Both modes run the same configuration, export, statistics, tool-library and STL assertions. Visible mode keeps setup dialogs off the screen and removes pauses between individual configuration checks. Time is spent on tool motion, playback, stock changes and completed scenes. Configuration widgets are still real widgets; WA_DontShowOnScreen suppresses their presentation, not their behavior.

Stage	Input	Demonstration and assertions
FANUC milling	milling/fanuc/flange_plate_benchmark.nc	Complete M30 execution, installed T2/T4 geometry, render scene and full logical playback. Options persistence, HTML statistics and expanded export/reimport remain regression checks.
3-axis GPU Stock Removal	Same flange	Only with an actual visible OpenGL 4.3+ widget. Real GPU playback and readback must show a lower remaining material height, allocated GPU buffers and complete replay. The machined stock remains visible before the next stage.
FANUC turning	turning/lathe_cycles_example.nc	Saved T0101-T0606 specifications, G71/G76 execution and full Stock Removal playback. The bore grows during internal threading while the outside stock contour stays intact. Rewind/replay restores identical final material intervals.
SINUMERIK 3+2	milling/sinumerik/5ax_test.mpf, stl/test6.stl	Angled AC table, changing tool orientations, toolpath/playback and positioned STL. Origin/translation assertions remain.
SINUMERIK impeller	milling/sinumerik/impeller.mpf, stl/test7.stl	Angled BC table, saved T60 taper-ball geometry, playback in 10% sections and final scene. Rotation/section/undo assertions remain; TRANS warnings are reported.

All NC paths above are relative to tests/fixtures. Large multi-axis examples use brief real playback and slider sections to keep the demonstration bounded. The flange and turning stock visit every logical motion. Visible full playback uses an 8 ms precise timer; regression mode uses a zero timer interval. Waits process Qt events and have explicit deadlines. The final summary remains visible for at least three seconds. Unexpected warnings or modal dialogs fail the stage.

GPU availability

The GPU stage checks the actual graphics widget context and its OpenGL version before enabling removal. Offscreen/minimal platforms, missing/invalid contexts and OpenGL versions below 4.3 produce an explicit SKIPPED (...) stage in stdout and the summary. The rest of Sandbox continues. An offscreen PASS confirms model and workflow assertions only; it does not validate visible GPU rendering. Once an adequate context is available, a rendering/removal failure fails the test instead of being converted into a skip. There is no CPU material-removal fallback.

Isolated setup

File > New clears the editor, toolpath, STL and stock before every input. G54-G59 offsets are zero. Configured Home is X=150, Y=0, Z=10 for turning (diameter display), X=0, Y=0, Z=100 for flange/test6, and X=0, Y=0, Z=300 for the impeller. Milling GPU stock uses automatic bounds, 2 mm resolution and accuracy preset 1.

Turning stock is diameter 130 mm, no initial bore, length 55 mm, front Z=1 mm, resolution 0.1 mm. The isolated saved boring tool T0303 uses tip orientation 2; T0505 is the ID groove and T0606 the internal thread tool. The impeller library snapshot is T60/D1: diameter 4 mm, taper 6 degrees, flute/body 25 mm each and total length 50 mm. Exact library resolution and unchanged fixture source are asserted.

STL checks preserve test6 origin and Z=-100 placement; test7 rotates Z by 90 degrees, sections at Y=0 and undoes only the section, then displays edges. Both temporary export files and HTML reports are re-read and checked before the scenario ends.
