BOOST_AUTO_TEST_CASE ( PCBExprGeometryDependentFunctionDetection )

Test that PCBEXPR_UCODE correctly identifies geometry-dependent functions during compilation.

Regression test for PNS track drag performance. The geometry-dependent flag controls whether segment-by-segment DRC evaluation is performed during routing. When no geometry-dependent functions exist in clearance rules, the expensive per-segment evaluation is skipped.

◆ BOOST_AUTO_TEST_CASE() [3/3]

BOOST_AUTO_TEST_CASE ( PNSLayerRangeSwapBehavior )

Test that PNS_LAYER_RANGE(1, 0) is swapped to (0, 1).

This is a minimal regression test for https://gitlab.com/kicad/code/kicad/-/issues/20355 The actual fix is in pns_kicad_iface.cpp syncPad() which skips creating an INNER_LAYERS SOLID on 2-layer boards. This test verifies the layer range behavior that motivated the fix.

		PNS_TEST_FIXTURE	)

Test that inheritTrackWidth selects the correct track based on cursor proximity.

Regression test for https://gitlab.com/kicad/code/kicad/-/issues/19123 When a pad has multiple tracks of different widths, the router should inherit the width of the track closest to the cursor, not just the minimum width.

◆ BOOST_FIXTURE_TEST_CASE() [3/4]

BOOST_FIXTURE_TEST_CASE	(	PNSSegmentSplitPreservesLockedState	,

Test that splitting a locked PNS segment preserves the locked marker on both halves.

Regression test for https://gitlab.com/kicad/code/kicad/-/issues/21564 When a locked track is split by a new route connecting to its middle, both resulting segments must retain the locked state.
